Run Ansible Backup Playbook Remotely

In this method you can run Ansible Backup playbook on a remote workstation and target it at controller-0.

• You need to have Ansible installed on your remote workstation, along with the Ansible Backup/Restore playbooks.
• Your network has IPv6 connectivity before running Ansible Playbook, if the system configuration is IPv6.

1. Log in to the remote workstation.

2. Provide an Ansible hosts file, either, a customized one that is specified using the -i option, or the default one that resides in the Ansible configuration directory (that is, /etc/ansible/hosts). You must specify the floating IP of the controller host. For example, if the host name is _Cluster, the inventory file should have an entry _Cluster, for example:

   ---all:

   hosts:

   wc68:

   ansible_host: 128.222.100.02

   _Cluster:

   ansible_host: 128.224.141.74

3. Create an ansible secrets file.

   ~(keystone_admin)]$ cat <<EOF > secrets.yml
   vault_password_change_responses:
       yes/no: 'yes'
       sysadmin*: 'sysadmin'
       (current) UNIX password: 'sysadmin'
       New password: 'Li69nux*'
       Retype new password: 'Li69nux*'
   admin_password: Li69nux*
   ansible_become_pass: Li69nux*
   ansible_ssh_pass: Li69nux*
   EOF

4. Run Ansible Backup playbook:

   ~(keystone_admin)]$ ansible-playbook <path-to-backup-playbook-entry-file> --limit host-name -i <inventory-file> -e "backup_user_local_registry=true"

   The generated backup tar file can be found in <host_backup_dir>, that is, /home/sysadmin, by default. You can overwrite it using the -e option on the command line or in an override file.

   Warning

   If a backup of the local registry images file is created, the file is not copied from the remote machine to the local machine. The inventory_hostname_docker_local_registry_backup_timestamp.tgz file needs to copied off the host machine to be used if a restore is needed.
