How to get updates for mirrored docker images?

How are you running Renovate?

Self-hosted

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

GitHub, 37.351

Please tell us more about your question or problem

We have a values.yaml file (Helm) which contains an image we'd like to have updated.

The image is mirrored into our own internal repository but the lookup for the update needs to be done in an external one (https://registry.k8s.io/)

I did find an old discussion and issue that sounds like it might be related but I have trouble parsing the actual outcome of those and or to create a working config.

I tried

    {
      matchDatasources: ["docker"],
      registryUrls: ["https://registry.k8s.io"]
    }

but that hasn't worked.

That wouldn't work anyway as it'd need additional rewriting.

• Our mirror: docker.stackable.tech/k8s/sig-storage/csi-provisioner
• Original location: registry.k8s.io/sig-storage/csi-provisioner

Can anyone help me create a rule that helps us and/or at least point us in the direction as to why the original packageRule doesn't work?

• Our renovate config for reference
• config.js for self-hosting

Try registryAliases

[lfrancke]

Thanks! That also didn't work. I must be doing something fundamentally wrong.
But I don't want to waste your time. I'll try to dig into it at some other time. I think with your suggestions I'm at least looking in the right direction.

Can you reproduce this in a public repository we can look at?

[lfrancke]

Yes. All of our stuff is open source:

• The config
• Config for self-hosted renovate
• One example repository with an example values.yaml

Please note that we now have mirrored a newer version of these images in our repository so this was already upgraded manually

I'm just going to assume that my config is still wrong.
I did run renovate with debug logs and didn't see anything with it trying to connect to registry.k8s.io but in the stats that are printed at the end I do see that it connects to docker.stackable.tech

[rarkins]

Please create a minimal repository which we can more easily debug, if you'd still like us to take a look. Instructions will follow to clarify what I mean

[lfrancke]

Thanks. I've put it on my todo list!

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
