[buildah/podman] MYSQL_* environment variables not working as expected

[o-alquimista]

I'm using Buildah to build an image based on this one, and Podman to run it. Environment variables, such as MYSQL_ROOT_PASSWORD, are not working as expected. The root user in mariadb is not assigned with the chosen password. Instead, it remains without a password, allowing me to login by simply running mysql -u root.

This is how I define the env. variable:

workingcontainer=$(buildah from docker.io/library/mariadb:10.5)

buildah config --env MYSQL_ROOT_PASSWORD="example_password" $workingcontainer

# other tasks...
# unmount and commit new image

Then I run the local image I just created. It is actually set inside the container. I confirmed that with echo $MYSQL_ROOT_PASSWORD on the running mariadb container.

My guess is that there is something wrong with the entrypoint scripts that perform the initial setup. But then the same setup works as expected when I use Docker instead of Podman/Buildah.

Things I've tried:

• Define the env. variables when running the container, in addition to defining it in the image build process:

  podman run (...) --env MYSQL_ROOT_PASSWORD=example_password image_name

Closing as not a bug. The problem originates from something else in my build setup, as I was unable to reproduce this issue with a simpler test case.

Oh good. I was starting to look and assume that the entrypoint was overwritten. I'll look at your other issue soon.
