Host is not allowed to connect to this MySQL server

I receive the following exception after running podman compose up -d. Seems like the mysql init script isn't running?

Reproduce the failure with podman compose up -d, then inspect the compose configuration and MySQL initialization behavior using the reported ER_HOST_NOT_PRIVILEGED error as the starting point. Done means the initialization grants the expected access and Ghost starts without the host-permission error.
