Hello guys, I have a goal to update the API versions in Kubernetes manifest files in my repositories. I have decided to use the kubernetes-api datasource for this. However, my manifest files are stored not in plain format but as Helm templates. I have enabled debugging and see the following messages in the log:

Could you please advise on the correct way to use Renovate for updating API versions in the manifests when Helm is used?

Thank you!

Logs (if relevant)

You're asserting it's a bug?

[AntonTsaberyaby]

I'm not sure. I don't fully understand how the kubernetes-api datasource should work. Is it meant to update non-templated manifests only, or should it also update Helm manifests? Could what I'm describing be a bug?

[viceice]

I think this can be easily supported by stripping templates before parsing in kubernetes manager as we already do in other managers

[rarkins]

I'm wondering why you selected the bug option, especially if you don't understand it.

[rarkins]

I will answer once it's corrected

[AntonTsaberyaby]

Thank you for bringing this to my attention. I will correct this

[rarkins]

Renovate expects this to be valid yaml which can be parsed.

You could work around this immediately by creating a custom regex manager to parse your files.

Alternatively, please create an example reproduction and we'll see if we can build in a capability to compile or strip out the templates first before parsing.

[AntonTsaberyaby]

Ok. I will prepare an reproduction repo.

Hi there,

Get your discussion fixed faster by creating a minimal reproduction. This means a repository dedicated to reproducing this issue with the minimal dependencies and config possible.

Before we start working on your issue we need to know exactly what's causing the current behavior. A minimal reproduction helps us with this. Discussions without reproductions are less likely to be converted to Issues.

To get started, please read our guide on creating a minimal reproduction.

Good luck,

The Renovate team

[viceice]

then please create a reproduction

[AntonTsaberyaby]

The same repo https://github.com/AntonTsaberyaby/jitsi-helm/tree/main

[viceice]

it's not a minimal reproduction

[AntonTsaberyaby]

@viceice I have added renovate.json to my repository and installed the Github application. What else needs to be done to provide you with a minimal reproduction?

[rarkins]

You need to reduce the number of dependencies and amount of config to minimal. Please read the linked guide above
