Podman OpenRC Restart Policy Manager

This OpenRC init script manages the startup and shutdown of Podman containers based on the restart-policy=always. It ensures that the containers are started automatically on system boot and stopped on system shutdown, and that they only start once networking is available.

Features

• Automatically starts Podman containers with restart-policy=always on system boot.
• Stops containers on system shutdown.
• Ensures containers start only after the network is up.
• Configurable for different users and Podman setups.

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/podman-openrc-restart-policy-manager.git
   cd podman-openrc-restart-policy-manager
   

2. Copy the script to the OpenRC init.d directory:

   sudo cp podman-container.sh /etc/init.d/podman-container
   

3. Make the script executable:

   sudo chmod +x /etc/init.d/podman-container
   

4. Enable the service to start on boot:

   sudo rc-update add podman-container default
   

5. Start the service:

   sudo service podman-container start
   

Configuration

The script uses the following configurable variables:

• PODMAN: The path to the Podman executable.
  Default: /usr/bin/podman
  To override, set the PODMAN environment variable:

  export PODMAN="/usr/local/bin/podman"
  

• CONTAINER_USER: The user under which the Podman containers should run.
  Default: root
  To override, set the CONTAINER_USER environment variable:

  export CONTAINER_USER="youruser"
  

These variables can be set globally or within the script itself to customize the behavior based on your environment.

Example configuration:

To configure the script for a custom Podman path and user, create or modify the /etc/env.d/99-podman file:

PODMAN="/usr/local/bin/podman"
CONTAINER_USER="podmanuser"

Troubleshooting

• If you encounter issues with containers not starting, check the logs with:

  sudo tail -f /var/log/messages
  

• Ensure that Podman is installed and the binary path is correct.
