STEPS TO REPRODUCE

• Use the latest kubernetes core collection ( according to this, it is 2.2.3 )
• drain cluster node with the settings described in the kubernetes core collection readme linked documentation for k8s_drain
• receive error about unsupported parameters for kubernetes.core.k8s_drain --> delete_options.delete_emptydir_data

- name: cordon and drain node 1
  kubernetes.core.k8s_drain:
    api_key: "{{ rancher_api_key }}"
    host: "{{ rancher_ds1_cluster_url }}"
    name: node1
    state: drain
    delete_options:
      terminate_grace_period: 120
      ignore_daemonsets: yes
      delete_emptydir_data: yes

EXPECTED RESULTS

A drained node even when pods with local dir data would be deployed there.

ACTUAL RESULTS

The k8s_drain module in the latest kubernetes.core collection seems to be missing the delete_emptydir_data parameter as described in the documentation. Or the documentation is not the right one for the 2.2.3 release of kubernetes.core.

fatal: [localhost]: FAILED! => {"changed": false, "msg": "Unsupported parameters for (kubernetes.core.k8s_drain) module: delete_options.delete_emptydir_data. Supported parameters include: host, proxy_headers, delete_options, proxy, ca_cert (ssl_ca_cert), state, api_key, client_cert (cert_file), client_key (key_file), validate_certs (verify_ssl), password, context, kubeconfig, persist_config, name, username."}

@kagehisa Thanks for reporting this issue. The delete_emptydir_data will be released kubernetes.core 2.3.0 release. The documentation link provided is for the latest devel branch (which will be cut to 2.3.0 once it is released). So you will have to wait for 2.3.0 release to get this feature. Thanks.

I'm going to go ahead and close this issue as it is resolved by #322 in the upcoming release.
