Migrate to new Service Containers

If you are currently still using standalone services configured under environment like MySQL for example, you can migrate them to the new services section which improves start-up times (in particular when using newer versions) and thus speeds up your entire test run.

In most cases, the new service container can be used as a drop-in replacement without requiring any changes to your code. Here is an example how this would look like for MySQL:

build:
  nodes:
    my-node:
      environment:
        mysql: 5.7   # <- remove this line

      services:
        mysql: 5.7   # <- add this line
        mariadb: 10  # <- or this one if you like
