Our goal is to support both MySQL and PostgreSQL as a backend wherever we need a database. Our latest addition in this area was PostgreSQL support for reporting, which will be released in the next few weeks. We don’t have PostgreSQL support for Icinga Certificate Monitoring yet. But it has already been worked on and the pull request for it is waiting to be tried. We would be happy to receive feedback in this regard so that we can fully merge PostgreSQL support as soon as possible.

While developing Docker images for Icinga 2, Icinga Web 2 and Icinga DB we stumbled over OpenShift which doesn’t allow images to run as root by default. One has to enable that explicitly. Also admins of K8s environments being more permissive by default may decide not to allow running as the superuser. So we’ve added a USER directive to our Dockerfiles to make our customers‘ compliance departments happy.
