Questions

What commands would you describe as essential for anyone who is starting out with Juju?

How do I upgrade Juju?

  • What is the difference between upgrading the client, the “controller model”, and other models?
  • And how do I monitor the upgrade process?

What is a charm upgrade?

  • Any advice for when a charm upgrade gets stuck?

What do I do if I want to upgrade an application from, say v9 to v10? Can a charm do that?

How do I get started writing charms?

  • Is there a boilerplate Juju charm using the operator charm tech framework I keep hearing about? If I want to do a “simple” charm how do I do it?
  • Is there an app that I might be able to try and charm? Maybe even a list of “beginners apps” that would be good to try and charm to understand juju better?

Why does juju status take so long?

Can you explain spaces and how they apply to Juju and MAAS?
