Output from credential-get missing project-name

[Garrett Neugent]

When first deploying on openstack, I followed this page [1] and ran the following command:

```
juju deploy charmed-kubernetes --overlay ~/openstack-overlay.yaml --trust

```

The yaml file was curl'd (and not modified) from the link provided on [1]. After some time, I noticed that the openstack-integrator unit was blocked (from juju status):

```
openstack-integrator/0* blocked idle 10 REDACTED missing required credential: project_name
```

After viewing the current credentials:

```
$ juju run -u openstack-integrator/0 'credential-get'
type: openstack
name: serverstack
region: serverstack
endpoint: http://REDACTED:5000/v3
identityendpoint: ""
storageendpoint: ""
credential:
  authtype: userpass
  attributes:
    password: REDACTED
    project-domain-name: user
    user-domain-name: user
    username: REDACTED
    version: "3"
  redacted: []
cacertificates: []
skiptlsverify: false
```

I noticed that `auth_url` and `project_name` were not present. To fix it, I added the minimum requirements to to a file with:

```
$ cat credentials
{
 "auth-url":"http://REDACTED:5000/v3",
 "username":"REDACTED",
 "password":"REDACTED",
 "project-name":"thogarre-k8s",
 "user-domain-name":"user",
 "project-domain-name":"user"
}
$ juju config openstack-integrator credentials="$(base64 ~/credentials)"
```

After this, the unit picked up the credentials and continued deployment successfully.

It looks like it's the project-name, specifically, that's missing from your credential-get output. The charm checks for either project-name or tenant-name[1] but neither is present.

The missing auth-url should be fine. The charm also checks for endpoint[2] and should use that if present.

For reference, `auth_url` comes from the `endpoint` field when using `juju trust`. Because of the variety of sources and formats that the auth info can come from, and the need to standardize it when it's sent over the relation to CK, there's a _normalize_creds function [1] that standardizes the credentials structure, and then get_credentials combines [2] the values from the different sources in a particular order (individual config fields override the combined credentials config field which overrides `juju trust`).

From discussion on Mattermost, it seems that the project-name is in the Juju client's local credentials.yaml file, so I'm not sure how it is not getting passed through, but it's definitely a required field.

here's my (redacted) credentials file and current juju version:

```
ubuntu@thogarre-bastion-2:$ cat ~/.local/share/juju/credentials.yaml
credentials:
  serverstack:
    thogarre:
      auth-type: userpass
      password: REDACTED
      project-domain-name: user
      project-name: thogarre
      user-domain-name: user
      username: thogarre
      version: "3"
ubuntu@thogarre-bastion-2:~/.kube$ juju --version
2.8.7-bionic-amd64
```

Thanks for sharing the solution. The same thing happened to me.

juju --version
