Some of the ways to determine job running order: * Standard stage-based progression: https://docs.gitlab.com/ee/ci/yaml/#stage (jobs within a stage may run in parallel) * Directed Acyclic Graph (DAG)formed by use of needs:: https://docs.gitlab.com/ee/ci/yaml/#needs * Use of dependencies: to make certain jobs await others for purpose of artifacts: https://docs.gitlab.com/ee/ci/yaml/#dependencies (jobs may still run in parallel if dependencies met, regardless of the job's outcome)
