How to allow only versions below a specific minor release when a package has a suffix

What would you like help with?

I would like help with my configuration

How are you running Renovate?

Self-hosted

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

GitLab

Please tell us more about your question or problem

We are currently running php for some of our applications and inside the dockerfile we currently use this version:

php:8.1.27-fpm

the problem we are currently facing is that Renovate with this global configuration it's not able to open any new mr:

"packageRules": [
{
"matchDatasources": ["docker"],
"matchPackageNames": ["php"],
"allowedVersions": "<= 8.2.0",
"separateMinorPatch": true
}
],

the problem is related to the suffix -fpm

we tried also this configuration:

"packageRules": [
{
"matchDatasources": ["docker"],
"matchPackageNames": ["php"],
"separateMinorPatch": true
}
],

In this case the new mr get opened with the proper suffix maintained but of course the allowedVersion property doesn't work anymore, so we also get updates for php 8.3 which we don't want

ultimatly we tried this configuration:

"packageRules": [
{
"matchDatasources": ["docker"],
"matchPackageNames": ["php"],
"allowedVersions": "<= 8.2.0",
"versioning": "regex:^(?<major>\\d+)(\\.(?<minor>\\d+))?(\\.(?<patch>\\d+))?(-(?<compatibility>.*))?$",
"separateMultipleMinor": true
}
],

this configuration respects the allowedVersions paramenter but it doesn't keep track of the patch release version, from the original patckage it tries to update it this way: php:8.1.27-fpm -> php:8.2-fpm

I'm probably missing a simple configuration here but I cannot find it, please point me in the right direction!

Thanks

Try experimenting with versionCompatibility and separating the suffix as the compatibility part

[ebeltramo96]

Perfect, it worked out prefectly by just adding:

"versionCompatibility": "^(?<version>[^-]+)(?<compatibility>-.*)?$",
