Comment 1 for bug 1955133

Thanks for taking the time to raise this bug. Indeed, the instructions at the website need to be updated; thank you for pointing that out.

If you source the microstack.rc file [0] and walk through the local add cloud instructions with interactive prompt for juju [1], it should set you straight as Juju will import the certificate into the cloud configuration based on the currently configure OS_* environment values.

Alternatively, you can update your ~/.local/share/juju/clouds.yaml file to add the ca-certificates key field with the contents of the microstack self-signed certificate [2].

As a note, you'll still need to go through the steps of creating the local simplestreams metadata sources.

An example of the one on my box is shown below for clarity:

clouds:
  microstack:
    type: openstack
    auth-types: [userpass]
    endpoint: https://192.168.6.43:5000/v3
    regions:
      microstack:
        endpoint: https://192.168.6.43:5000/v3
    ca-certificates:
