Finally got the time to implement some config validation for our renovate templates / presets and when running it I got a ton of fileMatch vs managerFilePatterns warnings:

 WARN: Config migration necessary
       "oldConfig": {
         "customManagers": [
           {
             "customType": "regex",

             "matchStrings": [
               "image:\\s+(?<depName>my\\.local\\.registry\\.net/[^:]+):(?<currentValue>[^\\s]+)"
             ],
             "datasourceTemplate": "docker",
             "depNameTemplate": "{{depName}}",
             "versioningTemplate": "docker"
           }
         ],
         "packageRules": [
           {
             "matchManagers": ["custom.regex"],
             "pinDigests": false,
             "groupName": "gitlab-ci-yml"
           }
         ]
       },
       "newConfig": {
         "customManagers": [
           {
             "customType": "regex",
             "managerFilePatterns": ["/^.*\\.gitlab-ci\\.yml$/"],
             "matchStrings": [
               "image:\\s+(?<depName>my\\.local\\.registry\\.net/[^:]+):(?<currentValue>[^\\s]+)"
             ],
             "datasourceTemplate": "docker",
             "depNameTemplate": "{{depName}}",
             "versioningTemplate": "docker"
           }
         ],
         "packageRules": [
           {
             "matchManagers": ["custom.regex"],
             "pinDigests": false,
             "groupName": "gitlab-ci-yml"
           }
         ]
       }

In case you are wondering, the template above:

include:
  - component: $CI_SERVER_FQDN/path/to/my/repo/lint@v0.4.0
    inputs:
      image: my.local.registry.net/my/image:v3.70.4-k8s-linting # here

Should update the image in the input field in my include block which are not recognised by gitlabci or gitlabci-include managers.

Anway, reading the docs and looking at the validation output I was under the impression that I could just replace fileMatch with managerFilePatterns add the extra slashes in the value. But instead renovate just didn't find the file anymore and wouldn't do anything, also without saying anything in the debug logs. We are running: renovate:37.440.7 but even with renovate:latest the file defined in fileMatch or managerFilePatterns was just not recognised. I reverted the change but obviously now I have the warnings open. So here's my question: should managerFilePatterns be a 1:1 replacement for fileMatch as highlighted in the validator? If yes I will dig in further, just wasn't clear to me reading the docs.

managerFilePatterns aren't supported in Renovate v37. If you're using the config validator then you need to pin it to the older version of Renovate that you're using.

Thank you very much @rarkins 👍
