 Container runner is the recommended approach for running containerized jobs on self-hosted runners. Container runner offers the ability to seamlessly define, publish, and use custom Docker images during job execution. Container runner also has the ability to manage dependencies or libraries through custom Docker images instead of enumerating dependencies as part of `steps` in the `.circleci/config.yml` file.
