+# Jobs
+
+Pipeline configuration begins with jobs. Jobs are the most fundamental element of a `.gitlab-ci.yml` file.
+
+Jobs are:
+
+- Defined with constraints stating under what conditions they should be executed.
+- Top-level elements with an arbitrary name and must contain at least the [`script`](../yaml/README.md#script) clause.
+- Not limited in how many can be defined.
+
+For example:
+
+```yaml
+job1:
+  script: "execute-script-for-job1"
+
+job2:
+  script: "execute-script-for-job2"
+```
+
+The above example is the simplest possible CI/CD configuration with two separate
+jobs, where each of the jobs executes a different command.
+Of course a command can execute code directly (`./configure;make;make install`)
+or run a script (`test.sh`) in the repository.
+
+Jobs are picked up by [runners](../runners/README.md) and executed within the
+environment of the runner. What is important is that each job is run
+independently from each other.
+
+## View jobs in a pipeline
+
+When you access a pipeline, you can see the related jobs for that pipeline.
+
+Clicking an individual job shows you its job log, and allows you to:
+
+- Cancel the job.
+- Retry the job.
+- Erase the job log.
+
+## See why a job failed
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/17782) in GitLab 10.7.
+
+When a pipeline fails or is allowed to fail, there are several places where you
+can find the reason:
+
+- In the [pipeline graph](../pipelines/index.md#visualize-pipelines), on the pipeline detail view.
+- In the pipeline widgets, in the merge requests and commit pages.
+- In the job views, in the global and detailed views of a job.
+
+In each place, if you hover over the failed job you can see the reason it failed.
+
+![Pipeline detail](img/job_failure_reason.png)
+
+In [GitLab 10.8](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/17814) and later,
+you can also see the reason it failed on the Job detail page.
+
+## The order of jobs in a pipeline
+
+The order of jobs in a pipeline depends on the type of pipeline graph.
+
+- For [regular pipeline graphs](../pipelines/index.md#regular-pipeline-graphs), jobs are sorted by name.
+- For [pipeline mini graphs](../pipelines/index.md#pipeline-mini-graphs), jobs are sorted by severity and then by name.
+
+The order of severity is:
+
+- failed
+- warning
+- pending
+- running
+- manual
+- scheduled
+- canceled
+- success
+- skipped
+- created
+
+For example:
+
+![Pipeline mini graph sorting](img/pipelines_mini_graph_sorting.png)
+
+## Group jobs in a pipeline
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/6242) in GitLab 8.12.
+
+If you have many similar jobs, your [pipeline graph](../pipelines/index.md#visualize-pipelines) becomes long and hard
+to read.
+
+You can automatically group similar jobs together. If the job names are formatted in a certain way,
+they are collapsed into a single group in regular pipeline graphs (not the mini graphs).
+
+You can recognize when a pipeline has grouped jobs if you don't see the retry or
+cancel button inside them. Hovering over them shows the number of grouped
+jobs. Click to expand them.
+
+![Grouped pipelines](img/pipelines_grouped.png)
+
+To create a group of jobs, in the [CI/CD pipeline configuration file](../yaml/README.md),
+separate each job name with a number and one of the following:
+
+- A slash (`/`), for example, `test 1/3`, `test 2/3`, `test 3/3`.
+- A colon (`:`), for example, `test 1:3`, `test 2:3`, `test 3:3`.
+- A space, for example `test 0 3`, `test 1 3`, `test 2 3`.
+
+You can use these symbols interchangeably.
+
+In the example below, these three jobs are in a group named `build ruby`:
+
+```yaml
+build ruby 1/3:
+  stage: build
+  script:
+    - echo "ruby1"
+
+build ruby 2/3:
+  stage: build
+  script:
+    - echo "ruby2"
+
+build ruby 3/3:
+  stage: build
+  script:
+    - echo "ruby3"
+```
+
+In the pipeline, the result is a group named `build ruby` with three jobs:
+
+![Job group](img/job_group_v12_10.png)
+
+The jobs are be ordered by comparing the numbers from left to right. You
+usually want the first number to be the index and the second number to be the total.
+
+[This regular expression](https://gitlab.com/gitlab-org/gitlab/blob/2f3dc314f42dbd79813e6251792853bc231e69dd/app/models/commit_status.rb#L99)
+evaluates the job names: `\d+[\s:\/\\]+\d+\s*`.
+
+## Specifying variables when running manual jobs
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/30485) in GitLab 12.2.
+
+When running manual jobs you can supply additional job specific variables.
+
+You can do this from the job page of the manual job you want to run with
+additional variables. To access this page, click on the **name** of the manual job in
+the pipeline view, *not* the play (**{play}**) button.
+
+This is useful when you want to alter the execution of a job that uses
+[custom environment variables](../variables/README.md#custom-environment-variables).
+Add a variable name (key) and value here to override the value defined in
+[the UI or `.gitlab-ci.yml`](../variables/README.md#custom-environment-variables),
+for a single run of the manual job.
+
+![Manual job variables](img/manual_job_variables.png)
+
+## Delay a job
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/21767) in GitLab 11.4.
+
+When you do not want to run a job immediately, you can use the [`when:delayed`](../yaml/README.md#whendelayed) keyword to
+delay a job's execution for a certain period.
+
+This is especially useful for timed incremental rollout where new code is rolled out gradually.
+
+For example, if you start rolling out new code and:
+
+- Users do not experience trouble, GitLab can automatically complete the deployment from 0% to 100%.
+- Users experience trouble with the new code, you can stop the timed incremental rollout by canceling the pipeline
+  and [rolling](../environments/index.md#retrying-and-rolling-back) back to the last stable version.
+
+![Pipelines example](img/pipeline_incremental_rollout.png)
+
+## Expand and collapse job log sections
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/14664) in GitLab 12.0.
+
+Job logs are divided into sections that can be collapsed or expanded. Each section displays
+the duration.
+
+In the following example:
+
+- Two sections are collapsed and can be expanded.
+- Three sections are expanded and can be collapsed.
+
+![Collapsible sections](img/collapsible_log_v12_6.png)
+
+### Custom collapsible sections
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/14664) in GitLab 12.0.
+
+You can create [collapsible sections in job logs](#expand-and-collapse-job-log-sections)
+by manually outputting special codes
+that GitLab uses to determine what sections to collapse:
+
+- Section start marker: `section_start:UNIX_TIMESTAMP:SECTION_NAME\r\e[0K` + `TEXT_OF_SECTION_HEADER`
+- Section end marker: `section_end:UNIX_TIMESTAMP:SECTION_NAME\r\e[0K`
+
+You must add these codes to the script section of the CI configuration. For example,
+using `echo`:
+
+```yaml
+job1:
+  script:
+    - echo -e "section_start:`date +%s`:my_first_section\r\e[0KHeader of the 1st collapsible section"
+    - echo 'this line should be hidden when collapsed'
+    - echo -e "section_end:`date +%s`:my_first_section\r\e[0K"
+```
+
+In the example above:
+
+- `date +%s`: The Unix timestamp (for example `1560896352`).
+- `my_first_section`: The name given to the section.
+- `\r\e[0K`: Prevents the section markers from displaying in the rendered (colored)
+  job log, but they are displayed in the raw job log. To see them, in the top right
+  of the job log, click **{doc-text}** (**Show complete raw**).
+  - `\r`: carriage return.
+  - `\e[0K`: clear line ANSI escape code.
+
+Sample raw job log:
+
+```plaintext
+section_start:1560896352:my_first_section\r\e[0KHeader of the 1st collapsible section
+this line should be hidden when collapsed
+section_end:1560896353:my_first_section\r\e[0K
+```
+
+### Pre-collapse sections
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/198413) in GitLab 13.5.
+
+You can make the job log automatically collapse collapsible sections by adding the `collapsed` option to the section start.
+Add `[collapsed=true]` after the section name and before the `\r`. The section end marker
+remains unchanged:
+
+- Section start marker with `[collapsed=true]`: `section_start:UNIX_TIMESTAMP:SECTION_NAME[collapsed=true]\r\e[0K` + `TEXT_OF_SECTION_HEADER`
+- Section end marker: `section_end:UNIX_TIMESTAMP:SECTION_NAME\r\e[0K`
+
+Add the updated section start text to the CI configuration. For example,
+using `echo`:
+
+```yaml
+job1:
+  script:
+    - echo -e "section_start:`date +%s`:my_first_section[collapsed=true]\r\e[0KHeader of the 1st collapsible section"
+    - echo 'this line should be hidden automatically after loading the job log'
+    - echo -e "section_end:`date +%s`:my_first_section\r\e[0K"
+```
