Docker_Backup

This Playbook enables Backups all persistent Volumes (no Bind Mounts) from a given List of Containers to a Folder of your choice. The Volume Data will be backed up as a compressed tar.

Requirements

  • Ansible 2.10

Playbook Variables

  • backup_location (Default /docker/backup): Defines the Backup Location of the Volumes.

  • container_list_to_backup: A Dictionary of Containers you want to backup. (Must be the same Name than in Docker).

    Example Container List:

    container_list_to_backup:
- container_name: myShinyContainer1
- container_name: myShinyContainer2

  • delete_old_backups (Default true): Controls if you want to delete old backups or not

  • backup_retention: Number of days for backups you want to get preserved. Older Backups will get deleted

Example Playbook run Command

An example Playbook Call looks like this. Ofcourse you may want to specify the Variables within your Playbook or within your Inventory:

- ansible-playbook -i hosts -e "HOSTS=myDockerHost" docker_backup.yml

Maybe you want to specify the Container Dictionary in a separate File. Then you can call the Playbook like so:

- ansible-playbook -i hosts -e "@container_list_to_backup.yml" -e "HOSTS=myDockerHost" docker_backup.yml
