CLI: delete by multiple names or ids

CLI: delete by multiple names or ids

https://blueprints.launchpad.net/python-saharaclient/+spec/cli-delete-by-multiple-names-or-ids

In sahara-cli you can only delete an object by name or id. In several os clients, such as nova and heat, you can delete an object by providing a list of ids or names. This blueprint is about adding this feature in sahara-cli.

Problem description

The CLI does not include deletion of objects by list of names or ids.

Proposed change

  • Long term solution

Our long term goal is to have the sahara-cli more consistent with other os clients.

Current CLI usage for cluster-delete:

sahara cluster-delete [--name NAME] [--id <cluster_id>]

Nova CLI usage for delete:

nova delete <server> [<server> ...]

In nova-cli, and other os clients, you pass directly the id(s) or the name(s) of the items you want to delete. We can refactor sahara-cli to remove the –name and –id arguments. So in long term the usage of sahara cli will be:

sahara cluster-delete <cluster> [<cluster> ...]

Positional arguments:
 <cluster>  Name or ID of cluster(s).``
  • Short term solution

Note that the CLI refactoring will take substantial time, so as short term solution, can temporary use –names and –ids for all delete verbs of the CLI. And once the CLI will be refactored, we will remove all –name(s) and –id(s) arguments.

So the proposed change implies to add –names and –ids arguments which consist of a Comma separated list of names and ids:

sahara cluster-delete [--name NAME] [--id cluster_id]
                      [--names NAMES] [--ids IDS]

Alternatives

No short term solution and just depend on the CLI refactoring to provide this feature.

Work Items

  • Add delete by list of names or ids in the CLI
  • Once the CLI is refactored, remove –name(s) –id(s) arguments

Dependencies

  • For long term solution: we depend on the refactoring of the CLI
  • For short term solution: none

Testing

Update the tests to delete list of names and ids

Documentation Impact

Documentation of the CLI needs to be updated
