Discussed in #33166

How are you running Renovate?

Self-hosted Renovate

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

GitLab ; Renovate 39.69.2

Please tell us more about your question or problem

When using an image with digest pointing to a specific architecture and os, renovate ensure the same architecture but can use another OS.

For example, this image:

registry.k8s.io/csi-vsphere/driver:v3.3.1@sha256:5ef2f153813565d41a41c0700d1917c077f30bbbe735fd3f9e9ba18956d65bed

which is os=linux architecture=amd64

Current behavior

Image is updated to:

registry.k8s.io/csi-vsphere/driver:v3.3.1@sha256:9245b0dbe11af8a90080e2d59a0e488bc6272b20d50eab3f643967c3d117a957

which is os=windows architecture=amd64

Expected behavior

Like for arcvhitecture, os should not be changed.

I think this is a known limitation when the manifest list doesn't contain the required image because it's not build yet. this is a regular issue on docker hub images.

[rarkins]

Should it self heal?

[viceice]

I think so

This PR is from an hour ago: https://github.com/renovate-reproductions/33166/pull/1/files

It's still windows

[sathieu]

This is not a manifest list but a manifest.
