Application Configuration

Not sure how to provide configuration since the chart cannot be even installed.

Describe the bug

Somehow helm thinks that username and password are not type string even if the error message says something different. Tried to be creative in the username and password field and fill in the base64 encoded string, just numbers, just letter. Even empty password (questions.yaml says, that it's optional).

To Reproduce

1. Open TruneNAS UI
2. Go to Apps
3. Open Available Applications
4. Scroll down or search for Prometheus (The TrueCharts one - currently in version 2.47.2_13.0.12)
5. Click Install
6. Fill all needed information
7. In the Remote Write section click Add
8. Fill the URL, Username and Password fields
9. Scroll down and click on Save
10. Wait for the error message

Expected Behavior

Install chart without any problems.

Screenshots

Additional Context

I want to store metrics in a remote Mimir instance.

I've read and agree with the following

• [X] I've checked all open and closed issues and my issue is not there.

Please update to a supported version of TrueNAS SCALE before opening a bugreport... Feel free to request reopen when updated.

[Hy3n4]

Sorry, I'm not sure what you mean by the upgrade, because I am running the latest version TrueNAS-SCALE-22.12.4.2 🤷‍♂️ If it's not supported version can you redirect me to a list of supported TrueNAS SCALE versions?

You've just edited your PR, previously you've stated to be using a non-supported older version in your PR. The list of supported versions is on the website.

[PrivatePuffin]

Even so, we do not accept bugreports for TrueNAS SCALE 22.12.4.2 either, please update to a version for which we accept bugreport, in accordance to the supported version list on the website

So, I just upgraded to TrueNAS-SCALE-23.10.0.1 and the error is still persisting and is still pretty much the same.

I've also updated the version in the original BR.

Actual error trace is below:

Hi, I've been digging a bit and it seems that prometheus api spec is expecting SecretKeySelector instead of pure paintext.

IMHO there has to be a secret file created as a part of the installation process and it should be referenced in the _prometheus.tpl template instead of passing the pure values from values.yaml.

[PrivatePuffin]

To be clear: Prometheus needs to be completely refactored from scratch. There is no use commenting on this further. so i'll lock this.

ALso: removeWrite isn't even a feature we ever aimed to support at this stage.
