[Fab-user] fabric, invoke - scaling up to support 100 hosts & SSH keys ?

OK, upgraded everything in my DEV environment to the latest versions.

What's a good strategy for scaling up to support 100 hosts & SSH keys?

My production environment uses a ~/.ssh/config file (with about 20 entries)

Can't get ~/.ssh/config working with Fabric 2.3.1 yet. (new DEV) It's not working yet, sigh...

Should I expect ~/.ssh/config to work with Fabric 2.X?

What about YAML file to bootstrap testing? YAML or JSON to get my DEV going?

Could something about my activated MiniConda DEV environment -- or the way Fabric's default config looks at the environment be causing me trouble?

Please advise.

Current production is running well (using ~/.ssh/config) -- but has a few nasty passphrase and SSH issues...

New DEV is running:
