Hi Team ,
I am using a repo A which fetches the dependencies for Package this ---> us-east1-docker.pkg.dev/d-gs-secops-cp/falcon/falcon-sensor:7.11.0-16404-1.falcon-linux.x86_64.Release.US-2 and updates the same in my private registry and i can see the new dependency update.

Now i am using another repo B which checks this package from the artifact registry and updates the dependency in my another repo but the issues is it is not able to update the same package in another repo

Renovate.json is as below

    {
      customType: 'regex',
      fileMatch: [
        'abc.gotmpl$'
      ],
      matchStrings: [
        'repository:\\s+(?<depName>[^:\\n]+)\\s*\\n\\s+tag:\\s+"?(?<currentValue>[^@\\n]+)@(?<currentDigest>sha256:[a-f0-9]+)"?',
      ],
      datasourceTemplate: 'docker',
      versioningTemplate: 'docker',
    },
  ],
and a package rule as 
    {
      matchDatasources: [
        'docker',
      ],
      matchPackageNames: [
        'us-east1-docker.pkg.dev/d-gs-secops-cp/falcon/falcon-sensor',         //Ensure falcon-senor use loose versioning for non-semver tags
      ],
      versioning: 'loose',
    }
    
contents of abc.gotmpl looks like 
    repository: xxxxxxx
    tag: 7.03.0-15805.falcon-linux.x86_64.Release.US-2@sha256:xxxxxxxxx    

I think what i am doing wrong is using versioningTemplate: 'docker', Instead use something like 'loose'
Not sure if anyone can help me on this , i would be thankful

Yes try loose versioning
