Health Check for Docker Containers

Description

This Ansible role is designed to ensure the health of Docker containers running on a system. It includes a script that checks for unhealthy or exited Docker containers and sets up a systemd service and timer to regularly execute this check.

Files

• vars/main.yml: Variable definitions for the script's directory.
• handlers/main.yml: Handlers to reload and restart the systemd service and timer.
• files/health-docker-container.sh: The script that checks the container health.
• tasks/main.yml: Tasks to create necessary directories, copy scripts, and create systemd service and timer.
• templates/health-docker-container.service.j2: Systemd service template.
• templates/health-docker-container.timer.j2: Systemd timer template.
• meta/main.yml: Meta information declaring dependencies for the role.

Usage

To use this role, include it in your playbook and set the path_administrator_scripts variable to the desired path for the health check scripts.

Ensure that the systemd_notifier dependency is satisfied for error notifications.
