Issue details

Command to delete elasticsearch is: sudo meza delete elasticsearch <environment-name>. This fails due to not properly loading all meza variables before running. Error is:

The task includes an option with an undefined variable. The error was: 'm_meza_data' is undefined

The error appears to have been in '/opt/meza/src/playbooks/delete-elasticsearch.yml': line 23, column 7, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


    - name: Remove {{ m_meza_data }}/elasticsearch
      ^ here
We could be wrong, but this one looks like it might be an issue with
missing quotes.  Always quote template expression brackets when they
start a value. For instance:

    with_items:
      - {{ foo }}

Should be written as:

    with_items:
      - "{{ foo }}"

Adding the following as the first task in src/playbooks/delete-elasticsearch.yml solves the problem:

  tasks:
    - include_role:
        name: set-vars
