Pass command line arguments to services
Description
I need to start MySQL with --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci options. The docker image supports my.cnf options:
docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
I didn't find any documentation on command line arguments for services, so I'm deducing that passing arguments to services is not supported at this time. Is there any way to pass my.cnf options, except building a custom image, in gitlab-ci.yml ?
Proposal
We have the command option in docker-compose for this purpose. It would be nice to add a similar option under services for gitlab-ci.yml.
