fix(values): consistent usage of postgresql.adminPasswordKey

[muja]

Description of the change

Consistently use adminPasswordKey. Overriding this value currently leads to buggy behavior because it is not consistently used everywhere. Specifically the hard-coded postgres-password in one of the extraEnvVars is causing issues and downstream values files cannot override that easily.

Additional Information

Since janus-idp.postgresql.secretName is not used anymore, could be considered to delete it, but it might break downstream charts which use that helper.

Checklist

• Chart version bumped in Chart.yaml according to semver.
• Variables are documented in the values.yaml and added to the README.md. The pre-commit utility can be used to generate the necessary content. Use pre-commit run -a to apply changes.
• JSON Schema template updated and re-generated the raw schema via pre-commit hook.
• List tests pass for Chart using the Chart Testing tool and the ct lint command.

Hi @rm3l

I believe I was missing a .. Should be fixed now.

[muja]

It seems that the context differs for the two invocations. The invocations on line 111/112 happen from the upstream chart, where the .Values.global look like this (weirdly):

{
    "auth": {
        "backend": {
            "enabled": true,
            "existingSecret": "",
            "value": ""
        }
    },
    "clusterRouterBase": "apps.example.com",
    "dynamic": {
        "includes": [
            "dynamic-plugins.default.yaml"
        ],
        "plugins": []
    },
    "host": "",
    "imagePullSecrets": [],
    "imageRegistry": ""
}

while the invocation in line 239/240 happens from the postgres chart, from who's POV they look like this:

{
    "auth": {
        "backend": {
            "enabled": true,
            "existingSecret": "",
            "value": ""
        }
    },
    "clusterRouterBase": "apps.example.com",
    "dynamic": {
        "includes": [
            "dynamic-plugins.default.yaml"
        ],
        "plugins": []
    },
    "host": "",
    "imagePullSecrets": [],
    "imageRegistry": "",
    "postgresql": {
        "auth": {
            "database": "",
            "existingSecret": "",
            "password": "",
            "postgresPassword": "",
            "secretKeys": {
                "adminPasswordKey": "",
                "replicationPasswordKey": "",
                "userPasswordKey": ""
            },
            "username": ""
        },
        "service": {
            "ports": {
                "postgresql": ""
            }
        }
    },
    "storageClass": ""
}

This causes the error. Any idea how to resolve this?

[muja]

That missing section is defined in the postgres chart's values.yaml file and when the invocation happens in the upstream chart, those values are not yet set/merged. I'm not a helm chart expert so I'm not sure what would be a good way to resolve this other than specifying empty objects in the values file:

global:
  postgresql:
    auth: {}
upstream:
  auth: {}

[muja]

using this helper here changes the name property from rhdh-chart-postgresql to rhdh-chart-backstage. Is that a breaking change / problem?
