Minimal CLI Options

Argparse (WIP pull request - https://review.openstack.org/66065)

Pros

• Fast-track to completing an M1 CLI
• Relatively simple Python standard argparse library-based code
• No external (potentially changing) code dependencies
• Modeled after Trove architecture recommendations

Cons

• May be the largest porting effort to the eventual OpenStack client of any options
• No authentication handling built in (likely need to make a dependency on the python keystone client - https://github.com/openstack/python-keystoneclient)

Cliff (no pull request)

https://cliff.readthedocs.org/en/latest/ Cliff Demo App: https://github.com/dreamhost/cliff/tree/master/demoapp

[Not very familiar with this library, can someone else provide benefits?]

OSC (WIP pull request/hack - https://review.openstack.org/#/c/64703/)

Note: dtroyer is PTL

Pros

• Considered by many to be the best path for integration into the future OpenStack CLI architecture
• Integrates authentication already
• dtroyer agreed to implement two Solum plugin features to provide an example

Cons

• Not complete - some APIs may change, especially around authentication
• The plugin documentation is not complete
• No other project has implemented the OSC plugin yet (core OpenStack projects add their features directly into the OSC without plugins)
• There are discussions about potential OSC architectural changes within OpenStack; want to verify that we will not be chasing large code changes
