Health Check for Docker Volumes
Description
This role checks for anonymous Docker volumes that are not bound to a container and may be left over from previous operations. It provides a cleanup mechanism by identifying such volumes, excluding any that are whitelisted, and possibly taking action against them.
Files

: Variable definitions for the script's directory and whitelist.handlers/main.yml
: Handlers to reload and restart the systemd service and timer.files/health-docker-volumes.sh
: The script that checks for anonymous Docker volumes and excludes whitelisted volumes.tasks/main.yml
: Tasks to create necessary directories, copy scripts, and create systemd service and timer.templates/health-docker-volumes.cymais.service.j2
: Systemd service template, including the whitelisted volumes as a parameter.templates/health-docker-volumes.cymais.timer.j2
: Systemd timer template.meta/main.yml
: Meta information declaring dependencies for the role.
Usage
Include this role in your playbook and set the path_administrator_scripts
variable to determine where the health check scripts should reside. Define whitelisted_anonymous_volumes
in vars/main.yml
with an array of volume IDs that should be ignored by the health check.
Ensure that the systemd-notifier
dependency is satisfied for error notifications.
