System Setup Script

A flexible bash script for automated installation of Java, Docker, and Docker Compose on Ubuntu/Debian systems.

한국어 문서

Features

• Java Installation: Install any OpenJDK version (8, 17, 21, 25, etc.)
• Docker Installation: Install Docker CE with proper user permissions
• Docker Compose: Install Docker Compose plugin
• Flexible Options: Skip any component with simple flags
• Order-Independent: Options can be specified in any order

Before using

On Debian/Ubuntu systems, ensure git is installed before cloning or running scripts from a repository.

sudo apt update && sudo apt install -y git

Clone this repository (replace with the actual repo URL and directory name):

git clone https://github.com/HyunwooKiim/setup.sh
cd setup.sh

Quick Start

# Make script executable
chmod +x setup.sh

# Run with default settings (Java 21 + Docker + Docker Compose)
./setup.sh

# Show guide
./setup.sh guide

Usage

./setup.sh [options...]

Options

Option	Description
guide	Show detailed usage guide
delete	Clean up script and related files
[number]	Install specific Java version (e.g., 21, 17, 11, 8)
javaless	Skip Java installation
dockerless	Skip Docker installation (automatically skips compose)
composeless	Skip Docker Compose installation
updateless	Skip system update
default	Use default configuration

Examples

# Install everything with defaults (Java 21 + Docker + Docker Compose)
./setup.sh

# Install Java 17 with Docker and Docker Compose
./setup.sh 17

# Install only Docker (no Java)
./setup.sh javaless

# Install only Java 21 (no Docker)
./setup.sh dockerless

# Install Java and Docker without Compose
./setup.sh composeless

# Install Java 11 and Docker without Compose
./setup.sh 11 composeless

# Skip system update, install only Java
./setup.sh updateless dockerless

# Multiple options (order doesn't matter)
./setup.sh javaless dockerless updateless

# Clean up script files after installation
./setup.sh delete

Delete Function

The delete option cleans up the script and related files after installation:

• If directory name is setup.sh:

  • Moves to parent directory and deletes the entire setup.sh directory

• If directory name is something else:

  • Deletes only: .git, README.md, koREADME.md, and setup.sh

# After successful installation, clean up
./setup.sh delete

Important Notes

• Option Order: Options can be specified in any order

  • ./setup.sh dockerless javaless = ./setup.sh javaless dockerless

• Automatic Dependencies:

  • Using dockerless automatically implies composeless (Docker Compose requires Docker)

• System Update:

  • System update (apt-get update && apt-get upgrade) runs by default
  • Use updateless to skip it

• Java Version:

  • Only numbers are accepted for Java version
  • Default is Java 21 (OpenJDK)
  • Common versions: 21, 17, 11, 8

• Docker Permissions:

  • Script automatically adds the ubuntu user to the docker group
  • You may need to log out and back in for group changes to take effect

Requirements

• Ubuntu/Debian-based Linux distribution
• sudo privileges
• Internet connection
