Mysql max_allowed_packet configuration

Hi!

You can use the command tool to increase the max_allowed_package to… 64MB with this:

    tests: &tests
      docker:
        - image: my-main-image:latest
        - image: mariadb:10.3
          environment:
            MYSQL_ALLOW_EMPTY_PASSWORD: 1
          command: [--max-allowed-packet=67108864]

That’s for mariadb, and I guess it’s similar for mysql. Here is a command to be able to see all available commands:
docker run -it --rm mariadb:10.3 --verbose --help

Here are all options you can configure for a docker executor: https://circleci.com/docs/2.0/configuration-reference/#docker
