🔐 Auth Service Integration

Merobox supports integrated authentication services with Traefik proxy and nip.io DNS resolution, enabling secure access to your Calimero nodes through web URLs.

Quick Start with Auth Service

# Start a single node with auth service
merobox run --auth-service

# Start multiple nodes with auth service
merobox run --count 2 --auth-service

# Stop everything (nodes + auth services)
merobox stop --all

What Gets Created

When you enable --auth-service, merobox automatically creates:

Traefik Proxy (proxy container) - Routes traffic and applies middleware
Auth Service (auth container) - Handles authentication and authorization
Docker Networks:
- calimero_web - External communication (Traefik ↔ Internet)
- calimero_internal - Secure backend communication (Auth ↔ Nodes)

URL Access

With Auth Service:

Node URLs: http://node1.127.0.0.1.nip.io, http://node2.127.0.0.1.nip.io, etc.
Auth Login: http://node1.127.0.0.1.nip.io/auth/login
Admin Dashboard: http://node1.127.0.0.1.nip.io/admin-dashboard

Without Auth Service:

Admin Dashboard: http://localhost:2528/admin-dashboard
Admin API: http://localhost:2528/admin-api/

Workflow Integration

Enable auth service in workflows by adding auth_service: true:

name: "My Auth Workflow"
description: "Workflow with authentication enabled"

# Enable auth service
auth_service: true

nodes:
  count: 1
  base_port: 2428
  base_rpc_port: 2528
  chain_id: "testnet-1"

steps:
  - name: "Wait for startup"
    type: "wait"
    seconds: 5

Architecture

Internet → Traefik (port 80) → Node Containers (calimero_web network)
                              ↓
                           Auth Service (calimero_internal network)

Public routes: /admin-dashboard (no auth required)
Protected routes: /admin-api/, /jsonrpc, /ws (auth required)
Auth routes: /auth/login, /admin/ (handled by auth service)

📖 Workflow Guide

Overview

Merobox workflows are defined in YAML files and executed through the bootstrap command. Workflows can include multiple steps like installing applications, creating contexts, managing identities, and executing function calls.

Workflow Structure

name: "Sample Workflow"
nodes:
  - calimero-node-1
  - calimero-node-2

steps:
  - name: "Install Application"
    type: "install"
    node: "calimero-node-1"
    path: "./app.wasm"
    outputs:
      applicationId: "app_id"

Step Types

Install Step

Installs WASM applications on Calimero nodes.

- name: "Install App"
  type: "install"
  node: "calimero-node-1"
  path: "./application.wasm" # Local path
  # OR
  url: "https://example.com/app.wasm" # Remote URL
  dev: true # Development mode
  outputs:
    applicationId: "app_id"

Context Step

Creates blockchain contexts for applications.

- name: "Create Context"
  type: "context"
  node: "calimero-node-1"
  application_id: "{{app_id}}"
  params:
    param1: "value1"
  outputs:
    contextId: "context_id"
    memberPublicKey: "member_key"

Identity Step

Generates cryptographic identities.

- name: "Create Identity"
  type: "identity"
  node: "calimero-node-2"
  outputs:
    publicKey: "public_key"

Invite Step

Invites identities to join contexts.

- name: "Invite Identity"
  type: "invite"
  node: "calimero-node-1"
  context_id: "{{context_id}}"
  grantee_id: "{{public_key}}"
  outputs:
    invitation: "invitation_data"

Join Step

Joins contexts using invitations.

- name: "Join Context"
  type: "join"
  node: "calimero-node-2"
  context_id: "{{context_id}}"
  invitee_id: "{{public_key}}"
  invitation: "{{invitation_data}}"

Create Mesh Step

Creates a context and connects multiple nodes in a single step. It automatically creates a context on the specified node, generates identities for each target node, sends invitations, and joins all nodes to the context.

- name: "Create Mesh"
  type: "create_mesh"
  context_node: "calimero-node-1"
  application_id: "{{app_id}}"
  nodes:
    - calimero-node-2
    - calimero-node-3
  capability: member # Optional, defaults to "member"
  outputs:
    context_id: contextId
    member_public_key: memberPublicKey

What it does:

Creates a context on the specified context_node
Creates identities on each node in the nodes list
Invites each node from the context node
Joins each node to the context

Parameters:

context_node: Node where the context will be created
application_id: Application ID to use for context creation
nodes: List of node names to create identities on and join to the context
capability: Optional capability for invitations (defaults to "member").

Exported variables:

context_id: The created context ID
member_public_key: The context creator's public key
public_key_{node_name}: Public key for each joined node (e.g., public_key_calimero-node-2)
public_key: If only one node is joined, also exported as just public_key

Execute Step

Executes smart contract functions.

- name: "Call Function"
  type: "call"
  node: "calimero-node-1"
  context_id: "{{context_id}}"
  method: "set"
  args:
    key: "hello"
    value: "world"
  executor_public_key: "{{member_key}}"
  outputs:
    result: "function_result"

Negative Testing with Expected Failures:

You can test error scenarios by setting expected_failure: true. When enabled, the step will continue even if the call fails, and error details are exported for assertions.

Both simple and complex output syntax are supported for error fields:

- name: "Expected Failure - Invalid Method"
  type: "call"
  node: "calimero-node-1"
  context_id: "{{context_id}}"
  executor_public_key: "{{member_public_key}}"
  method: "invalid_method_that_does_not_exist"
  args: {}
  expected_failure: true
  outputs:
    # Simple string assignment
    error_code: error_code # JSON-RPC error code
    error_type: error_type # Error type (e.g., "FunctionCallError")
    error_message: error_message # Error message
    error: error # Full error object

    # Complex dict-based assignment (also supported)
    custom_error:
      field: error_type
    custom_error_code:
      field: error_code
      target: error_code_{node_name} # Optional: custom target with node name

- name: "Assert Error Occurred"
  type: assert
  statements:
    - "is_set({{error_type}})"
    - "equal({{error_type}}, FunctionCallError)"
    - "contains({{error_message}}, not found)"
    - "equal({{custom_error}}, FunctionCallError)"

Error Handling:

JSON-RPC Errors: When a function call succeeds but returns a JSON-RPC error (e.g., invalid method, wrong arguments), error fields are extracted and exported.
Network/API Errors: When the API call itself fails (e.g., invalid context ID, network issues), error information is captured and exported.
Unexpected Success: If expected_failure: true but the call succeeds, a warning is shown and error fields are exported as None.

See workflow-examples/workflow-negative-testing-example.yml for comprehensive examples.

Wait Step

Adds delays between steps.

- name: "Wait"
  type: "wait"
  seconds: 5

Wait for Sync Step

Waits for nodes to reach consensus by verifying they have the same root hash. This is more reliable than fixed wait times because it only proceeds once nodes are actually synchronized.

- name: "Wait for Nodes to Sync"
  type: "wait_for_sync"
  context_id: "{{context_id}}"
  nodes:
    - calimero-node-1
    - calimero-node-2
  timeout: 30 # Max seconds to wait (default: 30)
  check_interval: 1 # Seconds between checks (default: 1.0)
  trigger_sync: true # Trigger sync before checking (default: true)
  outputs:
    root_hash: "synced_hash"
    elapsed_seconds: "sync_time"

Key Features:

Verifies root hash consensus across specified nodes
Fails workflow if nodes don't sync within timeout
Provides detailed sync progress logging
More reliable than fixed wait times
Captures sync metrics (time, attempts, final hash)

When to Use:

After state-changing operations (set, delete, update)
After nodes join a context
Before reading data from different nodes
In critical workflows where consistency is required

Repeat Step

Executes steps multiple times.

- name: "Repeat Operations"
  type: "repeat"
  count: 3
  steps:
    - name: "Set Value"
      type: "call"
      node: "calimero-node-1"
      context_id: "{{context_id}}"
      method: "set"
      args:
        key: "iteration_{{current_iteration}}"
        value: "value_{{current_iteration}}"
      executor_public_key: "{{member_key}}"
      outputs:
        result: "iteration_result"
    - name: "Wait"
      type: "wait"
      seconds: 2
  outputs:
    iteration: "current_iteration"

Fuzzy Test Step

Runs long-duration randomized load tests with weighted operation patterns and assertion-based validation.

- name: "Fuzzy Load Test"
  type: "fuzzy_test"
  duration_minutes: 30 # Run for 30 minutes
  context_id: "{{context_id}}"
  success_threshold: 95.0 # Pass if 95%+ assertions succeed

  nodes:
    - name: calimero-node-1
      executor_key: "{{member_public_key}}"
    - name: calimero-node-2
      executor_key: "{{public_key_node2}}"

  operations:
    # Pattern 1: Write and verify (40% of operations)
    - name: "set_and_verify"
      weight: 40
      steps:
        # Resolved args auto-captured as {{fuzzy_key}}, {{fuzzy_value}}
        - type: call
          node: "{{random_node}}" # Random node selection
          method: set
          context_id: "{{context_id}}"
          executor_public_key: "{{random_executor}}"
          args:
            key: "test_{{random_int(1, 1000)}}" # Random generators
            value: "{{uuid}}_{{timestamp}}"

        - type: wait
          seconds: 1

        # Use auto-captured {{fuzzy_key}}
        - type: call
          node: "{{random_node}}"
          method: get
          context_id: "{{context_id}}"
          executor_public_key: "{{random_executor}}"
          args:
            key: "{{fuzzy_key}}"
          outputs:
            retrieved: result

        # Use auto-captured {{fuzzy_value}}
        - type: assert
          non_blocking: true # Failures don't stop the test
          statements:
            - statement: "contains({{retrieved}}, {{fuzzy_value}})"
              message: "Value should match"

    # Pattern 2: Cross-node propagation test (30% of operations)
    - name: "cross_node_sync"
      weight: 30
      steps:
        # Args auto-captured as {{fuzzy_key}}, {{fuzzy_value}}
        - type: call
          node: calimero-node-1
          method: set
          context_id: "{{context_id}}"
          executor_public_key: "{{member_public_key}}"
          args:
            key: "sync_{{random_int(1, 500)}}"
            value: "{{timestamp}}"

        - type: wait
          seconds: 2 # Wait for propagation

        # Use auto-captured {{fuzzy_key}}
        - type: call
          node: calimero-node-2
          method: get
          context_id: "{{context_id}}"
          executor_public_key: "{{public_key_node2}}"
          args:
            key: "{{fuzzy_key}}"
          outputs:
            synced_value: result

        # Use auto-captured {{fuzzy_value}}
        - type: assert
          non_blocking: true
          statements:
            - statement: "contains({{synced_value}}, {{fuzzy_value}})"
              message: "Data should propagate across nodes"

    # Pattern 3: Random reads (30% of operations)
    - name: "random_read"
      weight: 30
      steps:
        - type: call
          node: "{{random_node}}"
          method: get
          context_id: "{{context_id}}"
          executor_public_key: "{{random_executor}}"
          args:
            key: "test_{{random_int(1, 1000)}}"

Random Value Generators:

{{random_int(min, max)}} - Random integer
{{random_string(length)}} - Random alphanumeric string
{{random_float(min, max)}} - Random float
{{random_choice([a, b, c])}} - Random choice from list
{{timestamp}} - Current Unix timestamp
{{uuid}} - Random UUID
{{random_node}} - Random node from nodes list
{{random_executor}} - Random executor key

Auto-Captured Arguments:

When a call step executes, its resolved arguments are automatically captured with a fuzzy_ prefix:

args.key → {{fuzzy_key}}
args.value → {{fuzzy_value}}
args.amount → {{fuzzy_amount}}

This allows subsequent steps to reference the exact values used in previous calls for verification.

Features:

Application-agnostic: Works with any smart contract
Weighted patterns: Control operation frequency
Non-blocking assertions: Track failures without stopping
Live progress: Periodic summaries every 60 seconds
Detailed reporting: Final report with pass rates and failure analysis

Upload Blob Step

Uploads files to blob storage and captures blob IDs for E2E testing.

- name: "Upload File to Blob Storage"
  type: "upload_blob"
  node: "calimero-node-1"
  file_path: "res/kv_store.wasm" # Path to file on local filesystem
  context_id: "{{context_id}}" # Optional: associate with context
  outputs:
    blob_id: "wasm_blob_id" # Capture the blob ID
    size: "wasm_blob_size" # Capture the blob size

# Use the blob ID in contract calls
- name: "Register Blob in Contract"
  type: "call"
  node: "calimero-node-1"
  context_id: "{{context_id}}"
  method: "register_blob"
  args:
    blob_id: "{{wasm_blob_id}}" # Use real blob ID from upload
    size: "{{wasm_blob_size}}" # Use real size from upload

Features:

Upload files from local filesystem to blob storage
Capture blob_id and size for use in subsequent steps
Optional context association via context_id
Full binary file support
Automatic error handling and validation

Dynamic Variables

Workflows support dynamic variable substitution using {{variable_name}} syntax.

Variable Sources

Step Outputs: Variables exported by previous steps
Workflow Context: Global workflow variables
Environment: System environment variables

Embedded Variables

Variables can be embedded within strings:

args:
  key: "user_{{user_id}}_data_{{iteration}}"

Variable Resolution

Variables are resolved at execution time
Missing variables cause workflow failures
Use outputs sections to export variables for later use

Output Configuration

Each step can export variables for use in subsequent steps:

outputs:
  variableName: "export_name" # Maps API response field to export name

Example Workflows

Basic Workflow: workflow-examples/workflow-example.yml - Complete example with dynamic variables
Negative Testing: workflow-examples/workflow-negative-testing-example.yml - Testing error scenarios with expected failures
Assertions: workflow-examples/workflow-assert-example.yml - Assertion and JSON assertion examples
Fuzzy Load Testing: workflow-examples/workflow-fuzzy-kv-store.yml - Long-running load test with randomized operations

Export variables from execute (call) steps

Call-like steps (type: call) return a JSON payload. You can export fields from that payload to named variables via the outputs mapping, and then reference those variables in subsequent steps using {{variable_name}}.

Example (from workflow-execute-variables-example.yml):

- name: Execute Get
  type: call
  node: calimero-node-2
  context_id: "{{ctx_id}}"
  executor_public_key: "{{member_key}}"
  method: get
  args:
    key: example_key
  outputs:
    # Simple field access
    read_value: result

    # Nested field access with automatic JSON parsing
    # If result contains { "output": "value" }, this extracts "value"
    nested_value: result.output

    # Deep nesting also works: result.data.user.name.first
    deeply_nested: result.data.user.name

- name: Echo Exported Value
  type: script
  target: local
  inline: |
    echo "Exported value is: {{read_value}}"
    echo "Nested value is: {{nested_value}}"

Syntax options:

Simple dotted path (recommended): Use dot notation to access nested fields. The system automatically parses JSON strings at each level.

outputs:
  my_value: result.output # Simple nested access
  deep_value: result.data.user.name # Deep nesting
  array_item: items.0.id # Array indexing

Dict-based syntax (legacy, still supported): For backward compatibility, you can use the explicit dict form:

outputs:
  my_value:
    field: result # top-level field name to read from
    json: true # parse JSON if the field is a JSON string
    path: output # dotted path inside the parsed JSON

Notes:

The outputs keys (e.g., read_value) become variables you can interpolate later as {{read_value}}.
For more advanced mappings (including per-node variable names), see workflow-custom-outputs-example.yml.

Running scripts in workflows (image, nodes, local) and passing args

The script step can execute a script in three ways:

target: image runs the script inside a temporary container created from the node image (before nodes are started)
target: nodes copies and runs the script inside each running Calimero node container
target: local runs the script on your host machine via /bin/sh

You can also pass arguments and reference exported variables using placeholders. Arguments are resolved before execution.

Example:

- name: Echo Exported Value
  type: script
  target: local # or "nodes" / "image"
  script: ./workflow-examples/scripts/echo-exported-value.sh
  args:
    - "{{read_value}}" # placeholder resolved from previous step outputs

Notes:

The script field must be only the path to the script; pass parameters via the args: list.
Placeholders in args are resolved using previously exported variables and workflow results.
For container targets, the script is copied into the container and executed with /bin/sh.

Assertion Steps

Assert (type: `assert`)

Statement-based assertions against exported variables and literals.

Supported forms:

is_set(A) / is_empty(A)
contains(A, B) / not_contains(A, B)
regex(A, PATTERN)
Comparisons: A == B, A != B, A >= B, A > B, A <= B, A < B
Equality helpers: equal(A, B), equals(A, B), not_equal(A, B), not_equals(A, B)

Placeholders like {{var}} are resolved before evaluation.

Example:

- name: Assert exported variables
  type: assert
  statements:
    - "is_set({{context_id}})"
    - "{{count}} >= 1"
    - "contains({{get_result}}, 'hello')"
    - "regex({{value}}, '^abc')"
    - "equal({{a}}, {{b}})"

JSON Assert (type: `json_assert`)

Compare JSON-like values (Python dict/list or JSON strings).

Supported forms:

json_equal(A, B) / equal(A, B)
json_subset(A, B) / subset(A, B) (B must be subset of A)

Example:

- name: Assert JSON equality of get_result
  type: json_assert
  statements:
    - "json_equal({{get_result}}, {'output': 'assert_value'})"

🎯 Local Blockchain Environments

Merobox offers two ways to run isolated tests without connecting to public networks. These options are mutually exclusive.

Local NEAR Sandbox (--near-devnet) A real, ephemeral NEAR blockchain instance running locally.

Best for: Full E2E testing and contract logic verification.
Behavior: Executes actual WASM smart contracts and state transitions.

Mock Relayer (--mock-relayer) A lightweight service that mimics the Relayer API.

Best for: Fast connectivity checks and node startup validation.
Behavior: Returns successful responses without executing real logic.

❌ Restriction: You cannot use --mock-relayer and --near-devnet simultaneously. The workflow will fail if both are enabled.

Local NEAR Sandbox

Merobox allows you to run workflows against a local ephemeral NEAR blockchain (Sandbox) instead of the public Testnet. This enables faster E2E testing without needing testnet tokens or RPC access.

Requirements

You need the compiled WebAssembly (.wasm) files for the Calimero context contracts:

calimero_context_config_near.wasm
calimero_context_proxy_near.wasm

How to Run

Use the --near-devnet flag and point to your contracts directory:

merobox bootstrap run workflows/my-test.yml \
  --near-devnet \
  --contracts-dir ./path/to/wasm/files

What happens during the run:

Sandbox Start: Merobox downloads and starts near-sandbox locally on port 3030.
Contract Deployment: It creates a root account (calimero.test.near) and deploys the registry contracts.
Node Configuration: It generates funded NEAR accounts for every node in your workflow (e.g., node-1.test.near).
Config Injection: It overrides the node's config.toml to point to the local sandbox RPC (http://host.docker.internal:3030 for Docker nodes).
Cleanup: The sandbox and all chain data are destroyed when the workflow finishes.

Configuration Files

Workflow Configuration

Workflows are defined in YAML files with the following structure:

name: "Workflow Name"

# Data cleanup options
nuke_on_start: false # Nuke all data before starting workflow
nuke_on_end: false # Nuke all data after completing workflow

# Image management
force_pull_image: false # Force pull Docker images even if they exist locally

# Node lifecycle
restart: false # Restart nodes at beginning
stop_all_nodes: true # Stop nodes after completion

# Network configuration
bootstrap_nodes: # Custom bootstrap nodes for DHT connectivity
  - "/ip4/x.x.x.x/udp/4001/quic-v1/p2p/<peer_id>"
  - "/ip4/x.x.x.x/tcp/4001/p2p/<peer_id>"

nodes:
  count: 2
  prefix: "node-name"
  # ... node configuration

steps:
  - name: "Step Name"
    type: "step_type"
    # ... step-specific configuration

Configuration Options:

nuke_on_start: When true, performs complete data cleanup (containers + data) before workflow starts. Ensures clean slate.
nuke_on_end: When true, performs complete data cleanup after workflow completes. Useful for CI/CD and testing.
force_pull_image: When set to true, forces Docker to pull fresh images from registries, even if they exist locally. Useful for ensuring latest versions or during development.
auth_service: When set to true, enables authentication service integration with Traefik proxy. Nodes will be configured with authentication middleware and proper routing.
config_path: Specify custom config.toml path for nodes. Supports both shared config for all nodes and per-node overrides. Skips node initialization when custom config is provided. See Custom Config Path for details.
near_devnet: When set to true, spins up a local NEAR Sandbox that is used for context management during the workflow running.
contracts_dir: Path to directory containing required WASM contracts (required when near_devnet is true).
bootstrap_nodes: List of multiaddr strings for DHT bootstrap nodes. When specified, nodes will connect to these peers for network discovery. Works independently of e2e_mode. Each multiaddr must end with a /p2p/<peer_id> component (e.g., "/ip4/63.181.86.34/tcp/4001/p2p/12D3KooW...").

Docker Image Management

Merobox provides automatic Docker image management to ensure your workflows always have the required images:

Automatic Image Pulling

Remote Detection: Automatically detects when images are from remote registries
Smart Pulling: Only pulls images that aren't available locally
Progress Display: Shows real-time pull progress and status

Force Pull Options

CLI Flag: Use --force-pull with the run command for individual operations
```
merobox run --image ghcr.io/calimero-network/merod:edge --force-pull
```

Workflow Configuration: Set force_pull_image: true in your workflow YAML

name: "My Workflow"
image: ghcr.io/calimero-network/merod:edge
force_pull_image: true # Will force pull all images
nodes:
  count: 2
  # ... other node configuration   ```

Use Cases

Development: Always get latest images during development
Testing: Ensure consistent image versions across environments
CI/CD: Force fresh pulls in automated workflows
Production: Update images without manual intervention

Environment Variables

CALIMERO_IMAGE: Docker image for Calimero nodes
DOCKER_HOST: Docker daemon connection string
LOG_LEVEL: Logging level (DEBUG, INFO, WARNING, ERROR)
RUST_BACKTRACE: RUST_BACKTRACE level (0, 1, full)
CALIMERO_AUTH_FRONTEND_FETCH: Set to 0 to use cached auth frontend (default is 1 for fresh fetch)
CALIMERO_WEBUI_FETCH: Set to 0 to use cached WebUI frontend (default is 1 for fresh fetch)

Custom Config Path

Merobox allows you to specify custom config.toml files for workflow nodes, enabling you to reuse existing node configurations without relying on Docker image initialization.

Usage in Workflows

You can specify a custom config path at two levels:

Shared config for all nodes:

nodes:
  config_path: ./custom-config.toml  # All nodes use this config
  calimero-node-1:
    port: 2428
    rpc_port: 2528
  calimero-node-2:
    port: 2429
    rpc_port: 2529

Per-node config override:

nodes:
  config_path: ./default-config.toml  # Default for all nodes
  calimero-node-1:
    port: 2428
    rpc_port: 2528
    # Uses default config
  calimero-node-2:
    port: 2429
    rpc_port: 2529
    config_path: ./special-config.toml  # Override for this node

Features

Shared or Per-Node: Specify a default config for all nodes or override per-node
Skip Initialization: When custom config is provided, node initialization is skipped
Docker & Binary Mode: Works with both Docker containers and native binary (--no-docker) mode
Path Resolution: Supports both absolute and relative paths
Validation: Validates config file existence before attempting to use it

Example

See workflow-examples/workflow-custom-config-example.yml and workflow-examples/custom-config.toml for a complete example.

Note: Custom config path is not supported with count mode (bulk node creation).

Log Level Configuration

Merobox provides flexible logging configuration for Calimero nodes through both CLI flags and workflow variables.

CLI Usage

# Use different log levels
merobox run --log-level info
merobox run --log-level warn
merobox run --log-level error
merobox run --log-level trace

# Use complex RUST_LOG patterns for specific module debugging
merobox run --log-level "info,calimero_context::handlers::execute=debug,calimero_node::handlers::network_event=debug"
merobox run --log-level "warn,calimero_server::ws=trace"

# Bootstrap workflows with custom log level
merobox bootstrap run workflow.yml --log-level "info,calimero_context::handlers::execute=debug"

Workflow Configuration

name: "My Workflow"
log_level: "info,calimero_context::handlers::execute=debug" # Set log level for all nodes in this workflow
nodes:
  count: 2
  # ... other node configuration

Available Log Levels

error: Only error messages (least verbose)
warn: Warning and error messages
info: Informational, warning, and error messages
debug: Debug, info, warning, and error messages (default)
trace: All messages including trace-level details (most verbose)

Complex RUST_LOG Patterns

RUST_LOG supports sophisticated logging configuration with module-specific levels:

# Set global level to info, but enable debug for specific modules
merobox run --log-level "info,calimero_context::handlers::execute=debug,calimero_node::handlers::network_event=debug"

# Set global level to warn, but enable trace for WebSocket handling
merobox run --log-level "warn,calimero_server::ws=trace"

# Multiple module-specific levels
merobox run --log-level "info,calimero_context::handlers::execute=debug,calimero_node::handlers::network_event=debug,calimero_server::ws=debug"

Pattern Syntax:

global_level - Sets the default log level
module::path=level - Sets specific level for a module path
Multiple patterns separated by commas
Use quotes to prevent shell interpretation of special characters

Usage Examples

# Production setup with minimal logging
merobox run --count 3 --log-level warn

# Development with maximum verbosity
merobox run --count 2 --log-level trace

# Workflow with custom log level
merobox bootstrap run production-workflow.yml --log-level info

Auth Service Integration

Merobox supports integration with Calimero's authentication service using Traefik as a reverse proxy. When enabled, nodes are automatically configured with:

Authentication Features

Protected API Endpoints: JSON-RPC and admin API routes require authentication
Public Admin Dashboard: Admin dashboard remains publicly accessible
WebSocket Protection: WebSocket connections are also authenticated
Automatic Routing: Traefik handles routing to node-specific subdomains

Network Configuration

Docker Networks: Automatically creates calimero_web and calimero_internal networks
Traefik Labels: Adds proper routing labels for each node
CORS Support: Configured CORS middleware for web access

Auth Frontend Management

Merobox provides flexible options for managing auth service frontend updates:

Fresh Frontend (Default): By default, auth service fetches fresh frontend resources (CALIMERO_AUTH_FRONTEND_FETCH=1)
Cached Mode: Use --auth-use-cached flag or set CALIMERO_AUTH_FRONTEND_FETCH=0 to use cached auth frontend
Custom Images: Specify custom auth images with --auth-image flag or auth_image in workflow config
Workflow Config: Set auth_use_cached: true in workflow YAML to use cached auth frontend

Environment Variable Usage:

# Use cached auth frontend for all auth service operations
export CALIMERO_AUTH_FRONTEND_FETCH=0
merobox run --auth-service

# Or set for single command
CALIMERO_AUTH_FRONTEND_FETCH=0 merobox run --auth-service

Node WebUI Frontend Management

Merobox provides flexible options for managing node WebUI frontend updates:

Fresh Frontend (Default): By default, nodes fetch fresh WebUI frontend resources (CALIMERO_WEBUI_FETCH=1)
Cached Mode: Use --webui-use-cached flag or set CALIMERO_WEBUI_FETCH=0 to use cached WebUI frontend
Custom Images: Specify custom node images with --image flag or image in workflow config
Workflow Config: Set webui_use_cached: true in workflow YAML to use cached WebUI frontend

Environment Variable Usage:

# Use cached WebUI frontend for all node operations
export CALIMERO_WEBUI_FETCH=0
merobox run --count 2

# Or set for single command
CALIMERO_WEBUI_FETCH=0 merobox run --count 2

Usage Examples

CLI Usage:

# Start nodes with auth service
merobox run --count 2 --auth-service

# Start nodes with custom auth image
merobox run --count 2 --auth-service --auth-image ghcr.io/calimero-network/mero-auth:latest

# Use cached auth frontend (instead of default fresh fetch)
merobox run --count 2 --auth-service --auth-use-cached

# Use cached WebUI frontend for nodes (instead of default fresh fetch)
merobox run --count 2 --webui-use-cached

# Use cached mode for both auth and WebUI
merobox run --count 2 --auth-service --auth-use-cached --webui-use-cached

# Run workflow with auth service
merobox bootstrap run workflow.yml --auth-service

# Run workflow with custom auth image
merobox bootstrap run workflow.yml --auth-service --auth-image ghcr.io/calimero-network/mero-auth:latest

# Run workflow with cached auth frontend
merobox bootstrap run workflow.yml --auth-service --auth-use-cached

# Run workflow with cached WebUI frontend
merobox bootstrap run workflow.yml --webui-use-cached

# Run workflow with both auth and WebUI in cached mode
merobox bootstrap run workflow.yml --auth-service --auth-use-cached --webui-use-cached

# Stop auth service stack
merobox stop --auth-service

Workflow Configuration:

name: "Frontend Management Workflow"
# Auth service configuration (fresh frontend is default, use cached if needed)
auth_service: true # Enable auth service for this workflow
auth_image: "ghcr.io/calimero-network/mero-auth:edge" # Custom auth image
auth_use_cached: true # Use cached auth frontend instead of fresh (optional)

# Node configuration (fresh WebUI is default, use cached if needed)
image: "ghcr.io/calimero-network/merod:edge" # Custom node image
webui_use_cached: true # Use cached WebUI frontend instead of fresh (optional)

nodes:
  count: 2
  prefix: "calimero-node"
steps:
  # ... your workflow steps

Access Patterns:

Node 1 API: http://calimero-node-1.127.0.0.1.nip.io/jsonrpc (protected)
Node 1 Dashboard: http://calimero-node-1.127.0.0.1.nip.io/admin-dashboard (public)
Auth Service: http://localhost/auth/ (authentication endpoints)

Automatic Service Management

When auth service is enabled, Merobox automatically:

Starts Traefik Proxy: Automatically pulls and starts traefik:v2.10 container
Starts Auth Service: Automatically pulls and starts ghcr.io/calimero-network/calimero-auth:latest container
Creates Docker Networks: Sets up calimero_web and calimero_internal networks
Configures Node Labels: Adds proper Traefik routing labels to node containers
Sets up Authentication: Configures forward authentication middleware
Enables CORS: Configures CORS for web access

Service Management:

Start: Services are started automatically when --auth-service flag is used
Stop: Use merobox stop --auth-service to stop Traefik and Auth service
Status Check: Services are checked and reused if already running

🛠️ Development Guide

Testing with Merobox

Merobox can be used as a lightweight test harness for your Python projects. Use the built-in helpers in merobox.testing to spin up ephemeral Calimero nodes for integration tests and tear them down automatically.

Basic Cluster Management

Context manager:

from merobox.testing import cluster

with cluster(count=2, prefix="ci", image="ghcr.io/calimero-network/merod:edge") as env:
    # env["nodes"] -> ["ci-1", "ci-2"]
    # env["endpoints"]["ci-1"] -> http://localhost:<rpc_port>
    ...  # call your code against the endpoints

Pytest fixture:

# conftest.py
from merobox.testing import pytest_cluster

merobox_cluster = pytest_cluster(count=2, scope="session")

# test_example.py
def test_something(merobox_cluster):
    endpoints = merobox_cluster["endpoints"]
    assert len(endpoints) == 2

Workflow-based Pretest Setup

For more complex test scenarios, you can run entire Merobox workflows as pretest setup:

Context manager:

from merobox.testing import workflow

with workflow("workflow-examples/workflow-example.yml", prefix="pretest") as env:
    # env["workflow_result"] -> True/False (workflow execution success)
    # env["nodes"] -> List of nodes created by the workflow
    # env["endpoints"] -> RPC endpoints for each node
    # env["manager"] -> DockerManager instance

    # Your test logic here
    # The workflow environment is automatically cleaned up on exit

Pytest fixture:

# conftest.py
from merobox.testing import pytest_workflow

merobox_workflow = pytest_workflow(
    workflow_path="workflow-examples/workflow-example.yml",
    prefix="pretest",
    scope="session"
)

# test_example.py
def test_with_workflow_setup(merobox_workflow):
    workflow_result = merobox_workflow["workflow_result"]
    assert workflow_result is True

    nodes = merobox_workflow["nodes"]
    endpoints = merobox_workflow["endpoints"]
    # ... your test logic

Options for workflow testing:

workflow_path: Path to the workflow YAML file
prefix: Node name prefix filter
image: Custom Docker image
chain_id: Blockchain chain ID
wait_for_ready: Whether to wait for nodes to be ready
scope: Pytest fixture scope (function, class, module, session)

See testing-examples/ for runnable examples including workflow pretest setup.

📋 Requirements

Python: 3.9 - 3.11
- Note: Python 3.12+ is currently not supported. The Near Sandbox feature uses py-near dependency relies on ed25519 package (that uses SafeConfigParser, which was removed in Python 3.12) that is limited by Python 3.11. Please use Python 3.11 or older.
Docker: 20.10+ for Calimero nodes
OS: Linux, macOS, Windows
- Note: Linux/macOS required for near-sandbox local devnet. Windows platform is not currently supported (you may try using WSL).

🚀 Releases & Publishing

Automated Release Process

Merobox uses a fully automated release pipeline. When you bump the version, everything else happens automatically!

How to Release

# 1. Update version in ONE place only
vim merobox/__init__.py  # Change __version__ = "0.1.28"

# 2. Commit and push to master
git add merobox/__init__.py
git commit -m "chore: bump version to 0.1.28"
git push origin master

# 3. That's it! The automation handles:
#    ✓ Creates git tag (v0.1.28)
#    ✓ Builds binaries for all platforms
#    ✓ Creates GitHub release
#    ✓ Publishes to PyPI

What Happens Automatically

Auto-Tagging (~ 5 seconds)
- Detects version change in __init__.py
- Creates and pushes tag vX.Y.Z
- Comments on commit with status
Build Binaries (~ 5-10 minutes)
- macOS x64 & arm64
- Linux x64 & arm64
- Generates SHA256 checksums
Create Release (~ 30 seconds)
- Publishes GitHub release with binaries
- Auto-generates release notes
Publish to PyPI (~ 1 minute)
- Builds Python package (sdist + wheel)
- Publishes to PyPI
- Publishes to TestPyPI (optional)

Version Management

Single Source of Truth: merobox/__init__.py
Dynamic Reading: pyproject.toml reads version from __init__.py automatically
No Duplication: Update version in one place only!

Workflow Pipeline

Version Bump → Auto-Tag → Build Binaries → GitHub Release → PyPI
   (manual)    (automated)   (automated)     (automated)   (automated)

Required Secrets

Configure these in GitHub repository settings:

PYPI_API_TOKEN - PyPI publishing token (required)
TEST_PYPI_API_TOKEN - TestPyPI token (optional)

Manual Publishing (Backup)

If you need to publish manually:

# Build package
make clean
make build

# Check package
make check-build

# Publish to PyPI
make publish

# Or publish to TestPyPI
make test-publish
