4.x delete script fails to delete cloudformation due to route53 hostedzone

[kaovilai]

hostedzone is unable to delete due to existing A records leftover from openshift-install

A records leftover are of this record name pattern

• api.cluster-guid.guid.base_domain
  • elb with tag uuid: <guid>
• *.apps.cluster-guid.guid.base_domain
  • elb with tag kubernetes.io/cluster/<cluster-name>: owned

where <cluster-name> is of pattern cluster-<shortened-guid>-<5-alphanumerics>
where <shortened-guid> is leftmost 13 characters from <guid>

can be fixed by deleting records in the hostedzone prior to deleting cloudformation stack.

As a workaround, you can iterate over all records via route53_info

    - name: grab zone id
      community.aws.route53_zone:
        zone: xn--mitlinuxwrdasnichtpassiert-ohc.de
      register: AWSINFO

    - name: grab Route53 record information
      community.aws.route53_info:
        query: record_sets
        hosted_zone_id: "{{ AWSINFO.zone_id }}"
      register: RECORDS

    - debug:
        var: RECORDS

and delete all records or just filter them ...
maybe this helps until the bug is fixed.

Because of the next related bug you'll hit, here comes the next workaround :)
When you're iterating over RECORDS.ResourceRecordSets, you can keep all properties.

    - name: remove all records
      community.aws.route53:
        state: absent
        hosted_zone_id: "{{ AWSINFO.zone_id }}"
        record: "{{ item.Name }}"
        type: "{{ item.Type }}"
        value: "{{ item.ResourceRecords |  map(attribute='Value') | list }}"
        ttl: "{{ item.TTL }}"
        overwrite: yes
      with_items: "{{ RECORDS.ResourceRecordSets }}"

This works for all non alias records.
When you also have alias records, you must exclude then with when: when: item.AliasTarget is not defined and run a 2nd task where you just delete the alias records.

Got poc working with ansible-collections/community.aws#801. Thanks @markuman !

Next up item that is not removed

• 3 OpenShift master/worker nodes. Tracking in 4.x delete script does not remove ocp4 cluster master/worker nodes. #189
