Instructions on the openproject site are apparently (badly) out of date

I followed the instructions in the section "All in one container", which appear to be the same as the ones found at https://github.com/opf/openproject/tree/dev/docs/installation-and-operations/installation/docker.

Either the deploy process, as described, is broken, or I totally misunderstood the instructions. Among the problems I found:

• the container has no postgres DBMS installed (I supplied one form the outside, creating role and database)
• an additional migration step was required (prbly because the external DBMS I supplied is postgres16)
• the container listens on port 8080 (the docs say 80)
• there is no user admin (or otherwise), all records in the users tables have no login field. I added a user through psql AND the ruby console (in the container)
• After the instance is up and running a number of functions (notably create prj from template/copy porject) appear not to be working (they post a spinner that never terminates, project is not copied/created).

Start with the “All in one container” section and the linked docs/installation-and-operations/installation/docker instructions. Compare the documented deployment with the reported PostgreSQL setup, migration step, port 8080 behavior, missing user, and project-copy failures. Done when the supported setup and prerequisites are accurately documented or the reported problems are confirmed and scoped.
