Docker-Kill-All

A Zsh utility that provides a convenient command to terminate all running Docker containers with enhanced reporting and container ID tracking. Works great on Pop OS and other Linux distributions.

Features

• Kill all running Docker containers with a single command
• Option to gracefully stop containers instead of force killing
• Display container IDs and names before operations
• Detailed success/failure reporting for each container
• Built-in confirmation prompt to prevent accidental termination
• Zsh command completion integration
• Error handling for Docker daemon connectivity issues

Prerequisites

• Zsh shell (can be installed via sudo apt install zsh)
• Docker installed and running
• Terminal access

Installation

Automatic Installation

# Clone the repository
git clone https://github.com/[your-username]/docker-kill-all.git

# Run the installation script
cd docker-kill-all
chmod +x add_docker_kill_all.sh
./add_docker_kill_all.sh

# Activate the function in your current session
source ~/.zshrc

Manual Installation

If you prefer to install manually, you can add the function directly to your ~/.zshrc file:

• Copy the docker-kill-all function to your ~/.zshrc file
• Activate the function source ~/.zshrc

Uninstallation

To remove the function from your Zsh, manually remove the function from ~/.zshrc

Usage

Basic usage (with confirmation prompt)

docker-kill-all

Force kill without confirmation

docker-kill-all -f

Gracefully stop containers instead of killing

docker-kill-all -s

Display help information

docker-kill-all -h

Example Output

Found 3 running containers:
  -  abc123def456 (nginx-proxy)
  -  fed987cba654 (mysql-db)
  -  123abc456def (redis-cache)

This will kill ALL running Docker containers listed above.
Are you sure you want to continue? (y/n) y

Killing all containers...

Results:
Successfully terminated containers:
  ✓ abc123def456 (nginx-proxy)
  ✓ fed987cba654 (mysql-db)
  ✓ 123abc456def (redis-cache)

All containers have been terminated successfully.

How It Works

The script adds a function to your Zsh configuration that:

1. Retrieves a list of all running Docker containers
2. Displays their IDs and names
3. Asks for confirmation (unless forced with -f)
4. Terminates each container using either docker kill or docker stop
5. Reports on the success or failure of each operation

Troubleshooting

Common Issues

• Command not found: Make sure you've sourced your .zshrc file after installation
• Docker daemon not running: Ensure Docker is running with systemctl status docker
• Permission denied: You may need to add your user to the docker group with: sudo usermod -aG docker $USER Then log out and back in

Docker Connection Issues

If you see Error: Cannot connect to Docker daemon, try:

• Check if Docker is running: systemctl status docker
• Start Docker if it's not running: sudo systemctl start docker

Compatibility

• Tested on: Pop OS 22.04, Ubuntu 20.04, Debian 11
• Requires: Zsh 5.0+ and Docker 19.03+
• Version: 1.0.0

Security Considerations

⚠️ Warning: This tool will terminate ALL running Docker containers. Use with caution in production environments. It's primarily designed for development and testing environments.
