"juju credentials" commands return different dictionaries for json and yaml output

[Francis Ginther]

This was seen with 2.0.1-xenial-amd64 and a bootstrapped maas cluster (although I don't know if this command actually requires a bootstrapped node):

ubuntu@landscape-xenial:~$ juju credentials --show-secrets scapestack --format yaml
credentials:
  scapestack:
    scapestack:
      auth-type: oauth1
      maas-oauth: [REDACTED]

ubuntu@landscape-xenial:~$ juju credentials --show-secrets scapestack --format json
{"credentials":{"scapestack":{"cloud-credentials":{"scapestack":{"auth-type":"oauth1","details":{"maas-oauth":"[REDACTED]"}}}}}}

The json version adds an extra layer, "cloud-credentials", that isn't in the yaml.

Expectation is that command would return the exact same data regardless of formatting in yaml or json.

Also seen with juju version 2.1-beta1-xenial-amd64.

There is also another extra layer in json format, "details, that isn't in the yaml.

So looking further at it, there is not much that we can do on Juju side. The problem seems to be on Json parser side - there is no json directive to say "print the contents of the map but not its name". We can do it in yaml but not in json.

So if we want to be consistent between yaml and json format, we can add the names of the maps to yaml output. So your example above would read:

$ juju credentials --show-secrets scapestack --format yaml
credentials:
  scapestack:
    cloud-credentials:
      scapestack:
        auth-type: oauth1
        details:
          maas-oauth: [REDACTED]
