# Docker Setup Script
|
||||
|
||||
A comprehensive bash script to set up Docker, Docker Compose, and GitHub CLI on Ubuntu/Debian systems with proper permissions and user configuration.
|
||||
|
||||
## Features
|
||||
|
||||
- ✅ System package updates
|
||||
- ✅ Docker Engine installation (if not present)
|
||||
- ✅ Docker Compose V2 plugin installation
|
||||
- ✅ GitHub CLI (gh) installation
|
||||
- ✅ Docker group configuration with proper permissions
|
||||
- ✅ `/srv/containers/` directory creation with ACL support
|
||||
- ✅ User added to docker group for sudo-less operation
|
||||
- ✅ Comprehensive error handling and status reporting
|
||||
|
||||
## Quick Start
|
||||
|
||||
### One-Line Installation
|
||||
|
||||
```bash
|
||||
curl -sL https://raw.githubusercontent.com/alexisskeates/docker-setup-script/main/docker-setup.sh | sudo bash
|
||||
```
|
||||
|
||||
### Manual Installation
|
||||
|
||||
```bash
|
||||
# Download the script
|
||||
curl -sL https://raw.githubusercontent.com/alexisskeates/docker-setup-script/main/docker-setup.sh -o docker-setup.sh
|
||||
|
||||
# Make it executable
|
||||
chmod +x docker-setup.sh
|
||||
|
||||
# Run it
|
||||
sudo ./docker-setup.sh
|
||||
```
|
||||
|
||||
## What It Does
|
||||
|
||||
### 1. System Updates
|
||||
- Updates package lists
|
||||
- Upgrades existing packages
|
||||
- Reports number of packages updated
|
||||
|
||||
### 2. Docker Installation
|
||||
- Checks if Docker is installed
|
||||
- Adds Docker's official GPG key and repository
|
||||
- Installs Docker Engine, CLI, containerd, and plugins
|
||||
- Enables Docker service to start on boot
|
||||
- Verifies Docker daemon is running
|
||||
|
||||
### 3. Docker Group Configuration
|
||||
- Creates docker group if it doesn't exist
|
||||
- Adds the current user to the docker group
|
||||
- Sets up proper permissions for group access
|
||||
|
||||
### 4. Docker Compose
|
||||
- Checks for Docker Compose V2 plugin
|
||||
- Installs if missing
|
||||
- Verifies installation
|
||||
|
||||
### 5. GitHub CLI
|
||||
- Checks if `gh` is installed
|
||||
- Adds GitHub CLI repository
|
||||
- Installs the latest version
|
||||
- Verifies installation
|
||||
|
||||
### 6. Container Directory Setup
|
||||
- Creates `/srv/containers/` directory
|
||||
- Sets ownership to `root:docker`
|
||||
- Applies `770` permissions (rwxrwx---)
|
||||
- Configures ACL for inherited permissions
|
||||
- Ensures all docker group members can access
|
||||
|
||||
### 7. Verification
|
||||
- Tests Docker access for the user
|
||||
- Provides summary of all installed components
|
||||
- Lists next steps for activation
|
||||
|
||||
## Post-Installation
|
||||
|
||||
After running the script, you'll need to activate the docker group membership:
|
||||
|
||||
### Option 1: Re-login (Recommended)
|
||||
```bash
|
||||
# Log out and log back in
|
||||
exit
|
||||
```
|
||||
|
||||
### Option 2: Activate in Current Session
|
||||
```bash
|
||||
# Start a new shell with docker group active
|
||||
newgrp docker
|
||||
```
|
||||
|
||||
### Verify Installation
|
||||
|
||||
```bash
|
||||
docker --version
|
||||
docker compose version
|
||||
docker ps
|
||||
gh --version
|
||||
```
|
||||
|
||||
## Requirements
|
||||
|
||||
- **OS**: Ubuntu 20.04+ or Debian 10+
|
||||
- **Privileges**: Must be run with `sudo`
|
||||
- **Network**: Internet connection required for package downloads
|
||||
|
||||
## Permissions
|
||||
|
||||
The script creates `/srv/containers/` with the following permissions:
|
||||
|
||||
```
|
||||
Owner: root (rwx)
|
||||
Group: docker (rwx)
|
||||
Others: --- (no access)
|
||||
```
|
||||
|
||||
This allows all members of the docker group to:
|
||||
- Create containers in `/srv/containers/`
|
||||
- Manage docker-compose projects
|
||||
- Share container configurations
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "Docker access requires logout/login"
|
||||
This is normal. The docker group membership requires a new login session. Use `newgrp docker` or log out/in.
|
||||
|
||||
### "Failed to update package lists"
|
||||
Check your internet connection and ensure apt sources are configured correctly.
|
||||
|
||||
### "Docker daemon is not running"
|
||||
Try: `sudo systemctl start docker` and check logs with `sudo journalctl -u docker`
|
||||
|
||||
## Security Notes
|
||||
|
||||
- The script must be run with `sudo` privileges
|
||||
- All docker group members have full access to `/srv/containers/`
|
||||
- Docker group membership is equivalent to root access
|
||||
- Only add trusted users to the docker group
|
||||
|
||||
## Directory Structure
|
||||
|
||||
After installation, you'll have:
|
||||
|
||||
```
|
||||
/srv/containers/ # Root directory for all containers
|
||||
├── (your projects) # Docker Compose projects
|
||||
└── ...
|
||||
```
