# 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
|
|
|
|
- `vars/main.yml`: 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.
