24.3.9 Upgrade Automation

Cause

Additional {{ }} in one of the MM yml files

Resolution

Workaround:

In the container, modify /opt/netops-deployment-tools-package-24.3.9-RELEASE/roles/camm/tasks/03.prepare_properties_installer.yml:

always:
    - name: Delete {{ pre_and_post_upgrade_camm_availability_check }} file
      ansible.builtin.file:
        state: absent
        path: "{{ remote_installer_dir }}/{{ item }}"
      with_items:
        - "{{ pre_upgrade_discover_camm_components }}"
        - "{{ camm.properties }}"

 

The last line should be    

      - "camm.properties" 

 

and not

      - "{{ camm.properties }}"
