[Feature Request]: Ability to add an `initContainer` for the MySQL StatefulSet about incubator-devlake-helm-chart HOT 3 OPEN

@JorgeGar Can you assign me to fix it? Facing the same issue.

@ProjectsOfMLee Assigned. Please tag me on the PR too so I can take a closer look.

I am unable to run the MySQL database on the k8s cluster as the mysql user wherein I set the securityContext to runAsUser with ID 999, as available in the mysql:8 image. Running as root is not an option either, due to security concerns.

This is the log:

2023-10-24 19:36:31+00:00 [Note] [Entrypoint]: Entrypoint script for MySQL Server 8.0.27-1debian10 started.

In order to circumvent this, I need to have an initContainer where I can override the file permissions on /var/lib/mysql to chmod it recursively with 999:999 permissions.

This is a request to add the ability to instantiate a new initContainer for the MySQL DB StatefulSet.

Hi @cicdguy am I correct assuming that user 999 is mysql user? If so, it seems that’s an issue to report on MySQL’s image.
In any case, adding the ability to create an initContainer could be nice. I encourage you to open a pull request adding it to the helm chart.
