When you use a `default` section with the `include` keyword, the defaults apply to all jobs in the pipeline. For example, you can use a `default` section with [`before_script`](index.md#before_script). Content of a custom configuration file named `/templates/.before-script-template.yml`: ```yaml default: before_script: - apt-get update -qq && apt-get install -y -qq sqlite3 libsqlite3-dev nodejs - gem install bundler --no-document - bundle install --jobs $(nproc) "${FLAGS[@]}" ``` Content of `.gitlab-ci.yml`: ```yaml include: '/templates/.before-script-template.yml' rspec1: script: - bundle exec rspec rspec2: script: - bundle exec rspec ``` The default `before_script` commands execute in both `rspec` jobs, before the `script` commands. ## Override included configuration values When you use the `include` keyword, you can override the included configuration values to adapt them to your pipeline requirements. The following example shows an `include` file that is customized in the `.gitlab-ci.yml` file. Specific YAML-defined variables and details of the `production` job are overridden. Content of a custom configuration file named `autodevops-template.yml`: ```yaml variables: POSTGRES_USER: user POSTGRES_PASSWORD: testing_password POSTGRES_DB: $CI_ENVIRONMENT_SLUG production: stage: production script: - install_dependencies - deploy environment: name: production url: https://$CI_PROJECT_PATH_SLUG.$KUBE_INGRESS_BASE_DOMAIN rules: - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH ``` Content of `.gitlab-ci.yml`: ```yaml include: 'https://company.com/autodevops-template.yml' image: alpine:latest variables: POSTGRES_USER: root POSTGRES_PASSWORD: secure_password stages: - build - test - production production: environment: url: https://domain.com ``` The `POSTGRES_USER` and `POSTGRES_PASSWORD` variables and the `environment:url` of the `production` job defined in the `.gitlab-ci.yml` file override the values defined in the `autodevops-template.yml` file. The other keywords do not change. This method is called *merging*. ## Override included configuration arrays You can use merging to extend and override configuration in an included template, but you cannot add or modify individual items in an array. For example, to add an additional `notify_owner` command to the extended `production` job's `script` array: Content of `autodevops-template.yml`: ```yaml production: stage: production script: - install_dependencies - deploy ``` Content of `.gitlab-ci.yml`: ```yaml include: 'autodevops-template.yml' stages: - production production: script: - install_dependencies - deploy - notify_owner ``` If `install_dependencies` and `deploy` are not repeated in the `.gitlab-ci.yml` file, the `production` job would have only `notify_owner` in the script. ## Use nested includes You can nest `include` sections in configuration files that are then included in another configuration. For example, for `include` keywords nested three deep: Content of `.gitlab-ci.yml`: ```yaml include: - local: /.gitlab-ci/another-config.yml ``` Content of `/.gitlab-ci/another-config.yml`: ```yaml include: - local: /.gitlab-ci/config-defaults.yml ``` Content of `/.gitlab-ci/config-defaults.yml`: ```yaml default: after_script: - echo "Job complete." ```
