Match only file in root directory of repo

[AKorezin]

I have a project with files

/test/docker-compose.yml
/docker-compose.yml

I want to match only file /docker-compose.yml. And I'm failed to do that.

I tried to use this config

{
  "extends": [
    "config:base",
  ],
  "pinDigests": true,
  "packageRules": [
    {
      "matchFiles": ["docker-compose.yml"],
      "pinDigests": false
    }
  ],
}

But I've got an error

{
  "validationMessage": "packageRules: Each packageRule must contain at least one selector (matchPackageRules, matchPaths, matchLanguages, matchBaseBranches, matchManagers, matchDatasources, matchDepTypes, matchPackageNames, matchPackagePatterns, excludePackageNames, excludePackagePatterns, matchCurrentVersion, matchSourceUrlPrefixes, matchUpdateTypes). If you wish for configuration to apply to all packages, it is not necessary to place it inside a packageRule at all."
}

So I tried to use this config

{
  "extends": [
    "config:base",
  ],
  "pinDigests": true,
  "packageRules": [
    {
      "matchPaths": ["/docker-compose.yml"],
      "pinDigests": false
    }
  ],
}

But it didn't match /docker-compose.yml.

How can I pin digests in /test/docker-compose.yml but not in /docker-compose.yml?

checkout matchFiles

Yes, found a bug, see #9084. Workaround:

{
  "extends": [
    "config:base",
  ],
  "pinDigests": true,
  "packageRules": [
    {
      "matchPaths": ["+(docker-compose.yml)"],
      "pinDigests": false
    }
  ],
}

see matchPaths for explanation

[AKorezin]

But it wouldn't match

/first-project/docker-compose.yml
/second-project/docker-compose.yml

So this files will remain without digests.

[viceice]

?? that rule should pin all digests excerpt /docker-compose.yml. Did you tried it?

[AKorezin]

Sorry my fault.
Placed file in /test/ directory in project.

[viceice]

yes, test folders are excluded by config:base, can be overriden by:

This is what worked for me:
"matchPaths": ["+(docker-compose.yml)"],
