#
# pipelines can be triggered manually in the web
#
# Currently the file is divided into subfiles. Each stage has a different file which
# can be found here: scripts/ci/gitlab/pipeline/<stage_name>.yml
#
# Instead of YAML anchors "extends" is used.

# SAMPLE JOB TEMPLATE - This is not a complete example but is enough to build a
# simple CI job. For full documentation, visit https://docs.gitlab.com/ee/ci/yaml/
#
# my-example-job:
#   stage:                           test # One of the stages listed below this job (required)
#   image:                           paritytech/tools:latest # Any docker image (required)
#   allow_failure:                   true # Allow the pipeline to continue if this job fails (default: false)
#   needs:
#     - job:                         test-linux # Any jobs that are required to run before this job (optional)
#   variables:
#     MY_ENVIRONMENT_VARIABLE:       "some useful value" # Environment variables passed to the job (optional)
#   script:
#     - echo "List of shell commands to run in your job"
#     - echo "You can also just specify a script here, like so:"
#     - ./scripts/ci/gitlab/my_amazing_script.sh
