Disable digest for a specific manager

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.

I've defined a RegEx manager to update the version of a Docker image in a source code file. The source code does not support digest, so what I need is just the version of the image. At the same time I've a compose file where the same image is used, where I would like to pin to the SHA.

Renovate now tries to pin to the RegEx manager managed version, which fails with WARN: Error updating branch: update failure, which makes sense, since there is no SHA there.

Is there a way that I can say on the RegEx manager that it should ignore digest, but still have the digest pinning in the compose file?

Yes, use packageRules with matchManagers

Thanks for the answer. Not sure how this works for my use-case though.

My manager looks like this:

  "customManagers": [
    {
      "customType": "regex",
      "fileMatch": ["src/**/*.cs"],
      "matchStrings": [
        "// renovate:( datasource=(?<datasource>.*?))? depName=(?<depName>.*?)( versioning=(?<versioning>.*?))?( extractVersion=(?<extractVersion>.*?))?\\s.*const string \\S*[iI]mageTag = \"(?<currentValue>\\S*)\";\\s?"
      ],
      "datasourceTemplate": "docker",
      "versioningTemplate": "docker"
    }
  ]

In the *.cs file it then looks like this:

// renovate: depName=myimage
private const string MyImageTag = "1.2.3";

Beside that I currently don't have any packageRules involved

Add a package rule with matchManagers=customer and pinDigests=false
