Правила для запуска по определенной ветке

Используется когда вам нужно запускать pipeline при коммите в определенную ветку

Пример 1:

stages:
 - primer

rules_on_one_job:
 stage: primer
 script:
  - |
    if [ "$CI_COMMIT_BRANCH" = "$CI_DEFAULT_BRANCH" ]; then
     echo "Pipeline run for head branch"
    elif [ "$CI_COMMIT_BRANCH" = "devel" ]; then
     echo "Pipeline run for branch: devel"
    else
     echo "Pipeline run for other branch: $CI_COMMIT_BRANCH"
    fi
 tags:
  - shell

Пример 2:

stages:
 - primer
 - primer_sec

rules_branch:
 stage: primer
 script:
  - echo "run job commit in main branch"
 rules:
  - if: '$CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH' 
 tags:
  - shell

rules_2_branch:
 stage: primer_sec
 script: 
  - echo "run job commit in '$CI_COMMIT_BRANCH' branch"
 rules:
  - if: '$CI_COMMIT_BRANCH == "devel"'
 tags: 
  - shell

Запуск по тегу

Запускается только когда есть Tag

Пример файла .gitlab-ci.yml

stages:
