Get version compatibility for "external" dependencies from documentation for Docker file

[zsoerenm]

How are you running Renovate?

A Mend.io-hosted app

Please tell us more about your question or problem

I've built a Docker container for Magento and I'd like to install Renovate to keep my "external" dependencies up to date. With external dependencies I mean MariaDB, Redis, Varnish, etc.

Magento provides a documentation file with a list of compatible dependencies. For example Magento 2.4.7-p3 is compatible with MariaDB 10.6. However, the latest version of MariaDB is 11.6.2 and, hence, Renovate wants to update it to 11.6.2.

Is there a way in Renovate to get the version compatibility from a documentation file?

Is there a way in Renovate to get the version compatibility from a documentation file?

No. That would require quite an extraordinary effort:

• Knowing in the first placed some arbitrary adobe.com file to check (and hope it doesn't change)
• Parsing its html
• Creating an understanding of the parsed data
• Altering lookup results based on the understanding

Is there a way to provide this data manually?
Maybe a comment in the Dockerfile?
