8. Build Options

In this section we’ll talk about global pipeline configuration. There are different options for global pipeline configuration. This helps to reduce code duplication in your pipeline.

8.1: Global pipeline configuration default

You can set global defaults for some keywords. Jobs that do not define one or more of the listed keywords use the value defined in the default section, therefore you can simply overwrite default values, by specifying the values explicitly in a job.

There are a couple of default settings you can define inside a default section:

  • after_script
  • artifacts
  • before_script
  • cache
  • image
  • interruptible
  • retry
  • services
  • tags
  • timeout

Let’s have a look at an example


default:
  before_script:
    - "This will be executed as default if no other before script is set"

job1:
  script:
    - echo "This script executes first. When it completes, the job's `after_script` executes."

job2:
  before_script:
    - echo "This script executes before the script block"
  script:
    - echo "This script executes first. When it completes, the job's `after_script` executes."
  after_script:
    - echo "Execute this script after the normal script."

This produces the following output:

This will be executed as default if no other before script is set
This script executes first. When it completes, the jobs `after_script` executes.

This script executes before the script block
This script executes first. When it completes, the jobs `after_script` executes.
Execute this script after the normal script.

Task 8.2: Global pipeline configuration lab

In this task you’re going to configure several things for your pipeline.

  • Create the default section
  • Create a global timeout of 5 minutes.
  • Add a retry number of 2 times to the info job, this means, that the job will be retried to succeed twice.

Edit the .gitlab-ci.yml, commit and push your changes and then verify the output of the pipeline run.

Solution

Updated .gitlab-ci.yml file for this lab:
