I've validated the issue and it's correct, the Docker images fro Kibana use RHEL not Ubuntu, so the docs aren't accurate. |
It's also based on RHEL rather than Ubuntu.

I think we need to verify if we need a version # here because we used to. I think it's also confusing to say that it's one or the other - I would guess that it's only wolfi if you specify wolfi per ## Hardened Docker images

The RHEL versions vary depending on the Elasticsearch version. For example, the 9.0.0 image uses RHEL 9.5 whereas the 9.1.0, 9.1.1, and 9.1.2 use RHEL 9.6.

Will add the link to the Wolfi section.

For my own education, why does the RHEL version matter in the context of an Elasticsearch container?

Oh sorry, only noticed that we used to specify a specific Ubuntu version. However, that version seems suspiciously old to me. (I checked and it's actually reached its end of life support in May 2025)
