How to properly point just dockerhub images to local mirror

Hey folks,
I'm using renovate with internal mirrored dockerhub repostory for a while now.
Now I'm faced with an issue where new repositories using multiple docker image sources fails.

So I guess the global redirect is causing problems whenever the dependency lookup points to these new sources:

default.json

{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "extends": ["config:recommended"],
  "dependencyDashboard": true,
  "enabledManagers": ["dockerfile", "docker-compose", "woodpecker", "bun", "npm", "nodenv"],
  "packageRules": [
    {
      "matchDatasources": ["docker"],
      "registryUrls": ["https://mirror.ocram85.com"]
    }
  ]
}

config.js

module.exports = {
  platform: 'gitea',
  endpoint: 'https://gitea.ocram85.com',
  gitAuthor: 'renovate-bot <[email protected]>',
  autodiscover: true,
  prHourlyLimit: 10,
  automerge: false,
  major: {
    automerge: false,
  },
  automergeType: 'pr',
  automergeStrategy: 'squash',
  labels: ['renovate'],
  dependencyDashboardLabels: ['renovate'],
  githubTokenWarn: false,
  semanticCommits: 'enabled',
  autodiscoverFilter: ['OCram85/*', 'arkanum/*', 'renovate-bot/*', 'plugins/gitea-package'],
}

renovate.json

{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "extends": ["local>renovate-bot/config"]
}

This is my full renovate setup just to reference.

The dependency lookup error appears on every repository which contains:

• dockerhub mirrored images ✔️ - ubuntu:22.04
• additional internal repositories ❌ - myimages.ocram85.com/myuser/myimage
• additional public repositories ❌ - ghcr.io/myuser/myimage

Unfortunately I couldn't find a detailed instruction or best practice how to just redirect the dockerhub / index.docker.io located images.

Is there anyone who could help pointing into the right direction to solve this?
