3-5: Validate Docker-in-Docker UsageThe
ghcr.io/devcontainers/features/docker-in-docker:2feature spins up a fully isolated Docker daemon and requires--privilegedmode. If your workflow only needs to build or run sibling containers (talk to the host Docker daemon), mounting the host socket (via the built-in Docker-socket feature or a bind mount of/var/run/docker.sock) is both safer and faster.Please review your dev workflow and confirm whether you truly need full DinD privileges before keeping this feature.

🧹 Nitpick (assertive)
Consider adding remoteUser and workspaceFolder for better DX
By default the container runs as root in /workspaces/<repo>, which may lead to permission quirks and verbose paths. A minimal augmentation could be:
"features": {
"ghcr.io/devcontainers/features/docker-in-docker:2": {}
- }
+ },
+ "remoteUser": "vscode",
+ "workspaceFolder": "/workspace"This follows Dev Container best-practices and prevents accidental root-owned artefacts on the host.

In .devcontainer.json lines 1 to 6, the configuration lacks the remoteUser and
workspaceFolder settings, causing the container to run as root in
/workspaces/<repo>, which can lead to permission issues and verbose paths. Add a
"remoteUser" property with a non-root user (e.g., "vscode") and set
"workspaceFolder" to a simpler path like "/workspace" to improve developer
experience and follow best practices.

Pin the container image to a digest for deterministic builds
Referencing the image without a digest means every rebuild could silently pull a newer, potentially incompatible layer set. Pinning to a sha256 digest guarantees reproducibility and guards against supply-chain surprises.

In .devcontainer.json at line 2, the image reference should be pinned to a
specific sha256 digest to ensure deterministic builds. Replace the current image
tag with the full image reference including the sha256 digest to guarantee
reproducible and secure builds.
