MongoDB 4.2 is not suitable for use as a service in Gitlab CI

[romintomasetti]

What's going on here?

Using the published Docker image of MongoDB (latest as of now, so 4.2.2 but I think the problem is the same with previous versions) as a service in Gitlab CI fails because the directory /home/mongodb/ is missing.

Error saving history file: FileOpenFailed: Unable to open() file /home/mongodb/.dbshell: No such file or directory

Proposed fix

See line

mongo/4.2/Dockerfile

Line 4 in fbaaf63

RUN groupadd -r mongodb && useradd -r -g mongodb mongodb

Instead, it should be:

RUN groupadd -r mongodb && useradd -r -m -g mongodb mongodb

so that the home directory is created. Tested, it seemed to fix the issue.
