+
+# Choose when to run jobs **(FREE)**
+
+When a new pipeline starts, GitLab checks the pipeline configuration to determine
+which jobs should run in that pipeline. You can configure jobs to run depending on
+the status of variables, the pipeline type, and so on.
+
+To configure a job to be included or excluded from certain pipelines, you can use:
+
+- [`rules`](../yaml/README.md#rules)
+- [`only`](../yaml/README.md#only--except)
+- [`except`](../yaml/README.md#only--except)
+
+Use [`needs`](../yaml/README.md#needs) to configure a job to run as soon as the
+earlier jobs it depends on finish running.
+
+## Specify when jobs run with `only` and `except`
+
+You can use [`only`](../yaml/README.md#only--except) and [`except`](../yaml/README.md#only--except)
+to control when to add jobs to pipelines.
+
+- Use `only` to define when a job runs.
+- Use `except` to define when a job **does not** run.
+
+### `only:refs` / `except:refs` examples
+
+`only` or `except` used without `refs` is the same as
+[`only:refs` / `except/refs`](../yaml/README.md#onlyrefs--exceptrefs)
+
+In the following example, `job` runs only for:
+
+- Git tags
+- [Triggers](../triggers/README.md#trigger-token)
+- [Scheduled pipelines](../pipelines/schedules.md)
+
+```yaml
+job:
+  # use special keywords
+  only:
+    - tags
+    - triggers
+    - schedules
+```
+
+To execute jobs only for the parent repository and not forks:
+
+```yaml
+job:
+  only:
+    - branches@gitlab-org/gitlab
+  except:
+    - main@gitlab-org/gitlab
+    - /^release/.*$/@gitlab-org/gitlab
+```
+
+This example runs `job` for all branches on `gitlab-org/gitlab`,
+except `main` and branches that start with `release/`.
+
+### `only: variables` / `except: variables` examples
+
+You can use `except:variables` to exclude jobs based on a commit message:
+
+```yaml
+end-to-end:
+  script: rake test:end-to-end
+  except:
+    variables:
+      - $CI_COMMIT_MESSAGE =~ /skip-end-to-end-tests/
+```
+
+You can use [parentheses](../variables/README.md#parentheses) with `&&` and `||`
+to build more complicated variable expressions:
+
+```yaml
+job1:
+  script:
+    - echo This rule uses parentheses.
+  only:
+    variables:
+      - ($CI_COMMIT_BRANCH == "master" || $CI_COMMIT_BRANCH == "develop") && $MY_VARIABLE
+```
+
+### `only:changes` / `except:changes` examples
+
+You can skip a job if a change is detected in any file with a
+`.md` extension in the root directory of the repository:
+
+```yaml
+build:
+  script: npm run build
+  except:
+    changes:
+      - "*.md"
+```
+
+If you change multiple files, but only one file ends in `.md`,
+the `build` job is still skipped. The job does not run for any of the files.
+
+Read more about how to use `only:changes` and `except:changes`:
+
+- [New branches or tags *without* pipelines for merge requests](#use-onlychanges-without-pipelines-for-merge-requests).
+- [Scheduled pipelines](#use-onlychanges-with-scheduled-pipelines).
+
+#### Use `only:changes` with pipelines for merge requests
+
+With [pipelines for merge requests](../merge_request_pipelines/index.md),
+it's possible to define a job to be created based on files modified
+in a merge request.
+
+Use this keyword with `only: [merge_requests]` so GitLab can find the correct base
+SHA of the source branch. File differences are correctly calculated from any further
+commits, and all changes in the merge requests are properly tested in pipelines.
+
+For example:
+
+```yaml
+docker build service one:
+  script: docker build -t my-service-one-image:$CI_COMMIT_REF_SLUG .
+  only:
+    refs:
+      - merge_requests
+    changes:
+      - Dockerfile
+      - service-one/**/*
+```
+
+In this scenario, if a merge request changes
+files in the `service-one` directory or the `Dockerfile`, GitLab creates
+the `docker build service one` job.
+
+For example:
+
+```yaml
+docker build service one:
+  script: docker build -t my-service-one-image:$CI_COMMIT_REF_SLUG .
+  only:
+    changes:
+      - Dockerfile
+      - service-one/**/*
+```
+
+In this example, the pipeline might fail because of changes to a file in `service-one/**/*`.
+
+A later commit that doesn't have changes in `service-one/**/*`
+but does have changes to the `Dockerfile` can pass. The job
+only tests the changes to the `Dockerfile`.
+
+GitLab checks the **most recent pipeline** that **passed**. If the merge request is mergeable,
+it doesn't matter that an earlier pipeline failed because of a change that has not been corrected.
+
+When you use this configuration, ensure that the most recent pipeline
+properly corrects any failures from previous pipelines.
+
+#### Use `only:changes` without pipelines for merge requests
+
+Without [pipelines for merge requests](../merge_request_pipelines/index.md), pipelines
+run on branches or tags that don't have an explicit association with a merge request.
+In this case, a previous SHA is used to calculate the diff, which is equivalent to `git diff HEAD~`.
+This can result in some unexpected behavior, including:
+
+- When pushing a new branch or a new tag to GitLab, the policy always evaluates to true.
+- When pushing a new commit, the changed files are calculated by using the previous commit
+  as the base SHA.
+
+#### Use `only:changes` with scheduled pipelines
+
+`only:changes` always evaluates as true in [Scheduled pipelines](../pipelines/schedules.md).
+All files are considered to have changed when a scheduled pipeline runs.
+
+### Combine multiple keywords with `only` or `except`
+
+If you use multiple keywords with `only` or `except`, the keywords are evaluated
+as a single conjoined expression. That is:
+
+- `only:` includes the job if **all** of the keys have at least one condition that matches.
+- `except:` excludes the job if **any** of the keys have at least one condition that matches.
+
+With `only`, individual keys are logically joined by an `AND`. A job is added to
+the pipeline if the following is true:
+
+- `(any listed refs are true) AND (any listed variables are true) AND (any listed changes are true) AND (any chosen Kubernetes status matches)`
+
+In the following example, the `test` job is only created when **all** of the following are true:
+
+- The pipeline is [scheduled](../pipelines/schedules.md) **or** runs for `main`.
+- The `variables` keyword matches.
+- The `kubernetes` service is active on the project.
+
+```yaml
+test:
+  script: npm run test
+  only:
+    refs:
+      - main
+      - schedules
+    variables:
+      - $CI_COMMIT_MESSAGE =~ /run-end-to-end-tests/
+    kubernetes: active
+```
+
+With `except`, individual keys are logically joined by an `OR`. A job is **not**
+added if the following is true:
+
+- `(any listed refs are true) OR (any listed variables are true) OR (any listed changes are true) OR (a chosen Kubernetes status matches)`
+
+In the following example, the `test` job is **not** created when **any** of the following are true:
+
+- The pipeline runs for the `main` branch.
+- There are changes to the `README.md` file in the root directory of the repository.
+
+```yaml
+test:
+  script: npm run test
+  except:
+    refs:
+      - main
+    changes:
+      - "README.md"
+```
+
+## Regular expressions
+
+The `@` symbol denotes the beginning of a ref's repository path.
+To match a ref name that contains the `@` character in a regular expression,
+you must use the hex character code match `\x40`.
+
+Only the tag or branch name can be matched by a regular expression.
+The repository path, if given, is always matched literally.
+
+To match the tag or branch name,
+the entire ref name part of the pattern must be a regular expression surrounded by `/`.
+For example, you can't use `issue-/.*/` to match all tag names or branch names
+that begin with `issue-`, but you can use `/issue-.*/`.
+
+Regular expression flags must be appended after the closing `/`. Pattern matching
+is case-sensitive by default. Use the `i` flag modifier, like `/pattern/i`, to make
+a pattern case-insensitive:
+
+```yaml
+job:
+  # use regexp
+  only:
+    - /^issue-.*$/i
+  # use special keyword
+  except:
+    - branches
+```
+
+Use anchors `^` and `$` to avoid the regular expression
+matching only a substring of the tag name or branch name.
+For example, `/^issue-.*$/` is equivalent to `/^issue-/`,
+while just `/issue/` would also match a branch called `severe-issues`.
+
+### `only` / `except` regex syntax
+
+In GitLab 11.9.4, GitLab began internally converting the regexp used
+in `only` and `except` keywords to [RE2](https://github.com/google/re2/wiki/Syntax).
+
+[RE2](https://github.com/google/re2/wiki/Syntax) limits the set of available features
+due to computational complexity, and some features, like negative lookaheads, became unavailable.
+Only a subset of features provided by [Ruby Regexp](https://ruby-doc.org/core/Regexp.html)
+are now supported.
+
+From GitLab 11.9.7 to GitLab 12.0, GitLab provided a feature flag to
+let you use unsafe regexp syntax. After migrating to safe syntax, you should disable
+this feature flag again:
+
+```ruby
+Feature.enable(:allow_unsafe_ruby_regexp)
+```

-Scheduled pipelines run on specific branches, so jobs configured with `only: branches`
-run on scheduled pipelines too. Add `except: schedules` to prevent jobs with `only: branches`
-from running on scheduled pipelines.
-
-In the following example, `job` runs only for refs that start with `issue-`.
-All branches are skipped:
-
-```yaml
-job:
-  # use regexp
-  only:
-    - /^issue-.*$/
-  # use special keyword
-  except:
-    - branches
-```
-
-Pattern matching is case-sensitive by default. Use the `i` flag modifier, like
-`/pattern/i`, to make a pattern case-insensitive:
-
-```yaml
-job:
-  # use regexp
-  only:
-    - /^issue-.*$/i

-For example, `job1` and `job2` are essentially the same:
+**Example of `only:refs` and `except:refs`**:

 job1:
-  script: echo 'test'
-
-job2:
-  script: echo 'test'
-  only: ['branches', 'tags']
-```
-
-#### Regular expressions
-
-The `@` symbol denotes the beginning of a ref's repository path.
-To match a ref name that contains the `@` character in a regular expression,
-you must use the hex character code match `\x40`.
-
-Only the tag or branch name can be matched by a regular expression.
-The repository path, if given, is always matched literally.
-
-To match the tag or branch name,
-the entire ref name part of the pattern must be a regular expression surrounded by `/`.
-For example, you can't use `issue-/.*/` to match all tag names or branch names
-that begin with `issue-`, but you can use `/issue-.*/`.
-
-Regular expression flags must be appended after the closing `/`.
-
-NOTE:
-Use anchors `^` and `$` to avoid the regular expression
-matching only a substring of the tag name or branch name.
-For example, `/^issue-.*$/` is equivalent to `/^issue-/`,
-while just `/issue/` would also match a branch called `severe-issues`.
-
-#### Supported `only`/`except` regexp syntax
-
-In GitLab 11.9.4, GitLab began internally converting the regexp used
-in `only` and `except` keywords to [RE2](https://github.com/google/re2/wiki/Syntax).
-
-[RE2](https://github.com/google/re2/wiki/Syntax) limits the set of available features
-due to computational complexity, and some features, like negative lookaheads, became unavailable.
-Only a subset of features provided by [Ruby Regexp](https://ruby-doc.org/core/Regexp.html)
-are now supported.
-
-From GitLab 11.9.7 to GitLab 12.0, GitLab provided a feature flag to
-let you use unsafe regexp syntax. After migrating to safe syntax, you should disable
-this feature flag again:
-
-```ruby
-Feature.enable(:allow_unsafe_ruby_regexp)
-```
-
-### `only`/`except` (advanced)
-
-GitLab supports multiple strategies, and it's possible to use an
-array or a hash configuration scheme.
-
-Four keys are available:
-
-- `refs`
-- `variables`
-- `changes`
-- `kubernetes`
-
-If you use multiple keys under `only` or `except`, the keys are evaluated as a
-single conjoined expression. That is:
-
-- `only:` includes the job if **all** of the keys have at least one condition that matches.
-- `except:` excludes the job if **any** of the keys have at least one condition that matches.
-
-With `only`, individual keys are logically joined by an `AND`. A job is added to
-the pipeline if the following is true:
-
-- `(any listed refs are true) AND (any listed variables are true) AND (any listed changes are true) AND (any chosen Kubernetes status matches)`
-
-In the following example, the `test` job is `only` created when **all** of the following are true:
-
-- The pipeline is [scheduled](../pipelines/schedules.md) **or** runs for `master`.
-- The `variables` keyword matches.
-- The `kubernetes` service is active on the project.
-
-```yaml
-test:
-  script: npm run test
+  script: echo
   only:
-    refs:
-      - master
-      - schedules
-    variables:
-      - $CI_COMMIT_MESSAGE =~ /run-end-to-end-tests/
-    kubernetes: active
-```
-
-With `except`, individual keys are logically joined by an `OR`. A job is **not**
-added if the following is true:
-
-- `(any listed refs are true) OR (any listed variables are true) OR (any listed changes are true) OR (a chosen Kubernetes status matches)`
-
-In the following example, the `test` job is **not** created when **any** of the following are true:
-
-- The pipeline runs for the `master` branch.
-- There are changes to the `README.md` file in the root directory of the repository.
+    - main
+    - /^issue-.*$/
+    - merge_requests
 
-```yaml
-test:
-  script: npm run test
+job2:
+  script: echo
   except:
-    refs:
-      - master
-    changes:
-      - "README.md"
+    - main
+    - /^stable-branch.*$/
+    - schedules
 ```
 
-#### `only:refs`/`except:refs`
+**Additional details:**
 
-> `refs` policy introduced in GitLab 10.0.
+- Scheduled pipelines run on specific branches, so jobs configured with `only: branches`
+  run on scheduled pipelines too. Add `except: schedules` to prevent jobs with `only: branches`
+  from running on scheduled pipelines.
+- `only` or `except` used without any other keywords are equivalent to `only: refs`
+  or `except: refs`. For example, the following two jobs configurations have the same
+  behavior:
 
-The `refs` strategy can take the same values as the
-[simplified only/except configuration](#onlyexcept-basic).
-
-In the following example, the `deploy` job is created only when the
-pipeline is [scheduled](../pipelines/schedules.md) or runs for the `master` branch:
+  ```yaml
+  job1:
+    script: echo

-#### `only:kubernetes`/`except:kubernetes`
+        - branches
+  ```
 
-> `kubernetes` policy introduced in GitLab 10.0.
+- If a job does not use `only`, `except`, or [`rules`](#rules), then `only` is set to `branches`
+  and `tags` by default.
 
-The `kubernetes` strategy accepts only the `active` keyword.
+  For example, `job1` and `job2` are equivalent:
 
-In the following example, the `deploy` job is created only when the

-#### `only:variables`/`except:variables`
+#### `only:variables` / `except:variables`
 
-> `variables` policy introduced in GitLab 10.7.
+Use the `only:variables` or `except:variables` keywords to control when to add jobs
+to a pipeline, based on the status of [CI/CD variables](../variables/README.md).
 
-The `variables` keyword defines variable expressions.
+**Keyword type**: Job keyword. You can use it only as part of a job.
 
-These expressions determine whether or not a job should be created.
+**Possible inputs**: An array of [CI/CD variable expressions](../variables/README.md#cicd-variable-expressions).
 
-Examples of variable expressions:
+**Example of `only:variables`**:

   only:
-    refs:
-      - branches
     variables:

-  except:
-    variables:

-```
-
-You can use [parentheses](../variables/README.md#parentheses) with `&&` and `||` to build more complicated variable expressions.
-[Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/230938) in GitLab 13.3:

-In this scenario, if a merge request changes
-files in the `service-one` directory or the `Dockerfile`, GitLab creates
-the `docker build service one` job.
-
-For example:
-
-```yaml
-docker build service one:
-  script: docker build -t my-service-one-image:$CI_COMMIT_REF_SLUG .
+deploy:
   only:
-    changes:
-      - Dockerfile
-      - service-one/**/*
+    kubernetes: active
 ```
 
-In this example, the pipeline might fail because of changes to a file in `service-one/**/*`.
-
-A later commit that doesn't have changes in `service-one/**/*`
-but does have changes to the `Dockerfile` can pass. The job
-only tests the changes to the `Dockerfile`.
-
-GitLab checks the **most recent pipeline** that **passed**. If the merge request is mergeable,
-it doesn't matter that an earlier pipeline failed because of a change that has not been corrected.
-
-When you use this configuration, ensure that the most recent pipeline
-properly corrects any failures from previous pipelines.
-
-##### Use `only:changes` without pipelines for merge requests
-
-Without [pipelines for merge requests](../merge_request_pipelines/index.md), pipelines
-run on branches or tags that don't have an explicit association with a merge request.
-In this case, a previous SHA is used to calculate the diff, which is equivalent to `git diff HEAD~`.
-This can result in some unexpected behavior, including:
-
-- When pushing a new branch or a new tag to GitLab, the policy always evaluates to true.
-- When pushing a new commit, the changed files are calculated by using the previous commit
-  as the base SHA.
-
-##### Use `only:changes` with scheduled pipelines
-
-`only:changes` always evaluates as true in [Scheduled pipelines](../pipelines/schedules.md).
-All files are considered to have changed when a scheduled pipeline runs.
+In this example, the `deploy` job runs only when the Kubernetes service is active
+in the project.
