Each shell has its own set of reserved variable names. job, which is passed to the downstream pipeline. These variables contain But sadly this doesn't work. For a project variable, itll be defined for pipelines inside that project, whereas instance-level variables will be available to every pipeline on your GitLab server. Push all the files you created to a new branch, and for the pipeline result, you should see the two jobs and their subsequent child jobs. The name you choose must be compatible with the shell thatll run your job if you pick a reserved keyword, your job could fail. There are a couple of other options however. There might be a way to get the last run job of a given branch, but I don't remember. And is it possible to pass variables (or artifacts) from downstream to upstream ? The child pipeline publishes its variable via a report artifact. To configure child pipelines to run when triggered from a merge request (parent) pipeline, use rules or workflow:rules. but there are key differences. GitLab CI/CD is a powerful continuous integration tool that works not only per project, but also across projects with multi-project pipelines. In the GitLab configuration file we have: a generation job and a trigger job.

Introduced in GitLab 13.12, the ~ character can be used in masked variables. You cannot use this method to forward job-level persisted variables Thanks in advance. The group variables that are available in a project are listed in the projects The Linux build child pipeline (.linux-gitlab-ci.yml) has the following configuration, and unless you want to trigger a further child pipeline, it follows standard a configuration format: In both cases, the child pipeline generates an artifact you can download under the Job artifacts section of the Job result screen. To learn more, see our tips on writing great answers. We use artifacts to save the generated child configuration files for this CI run, making them available for use in the child pipelines stages. Variable Passing Options variables in trigger job This usage is documented here: https://docs.gitlab.com/13.4/ee/ci/multi_project_pipelines.html#passing-variables-to-a-downstream-pipeline ( documentation => we may need this info also in the parent-child docs) It has some problems though. By using variable inheritance. For more information, please visit the dotenv homepage. Therefore, I have to take a detour via a new job that read the variable from the child and create a new dotenv report artifact. How to pass values to gitlab pipeline variable sourced from a file accessing variable values. For example, For your case, assuming the 'building' and 'deploying' jobs both run on the main branch, you can hopefully pass the artifact like so. available for use in pipeline configuration and job scripts. When you use needs:project to pass artifacts to a downstream pipeline, Splitting complex pipelines into multiple pipelines with a parent-child relationship can improve performance by allowing child pipelines to run concurrently. to a downstream pipeline, as they are not available in trigger jobs. Why does Acts not mention the deaths of Peter and Paul?

For example, you can store multiple values separated by a space in a variable, Gitlab child pipeline with dynamic configuration in 5 minutes echo "This job runs in multi-project pipelines only", $CI_PIPELINE_SOURCE == "merge_request_event", echo "This job runs in merge request pipelines only", echo "This job runs in both multi-project and merge request pipelines", generate-ci-config > generated-config.yml, echo "This child pipeline job runs any time the parent pipeline triggers it. Values can be wrapped in quotes, but cannot contain newline characters. I might test it myself. How to get started with Parent-child pipelines | GitLab This can be a safer way to inject sensitive data if your application is prepared to read the final value from the specified file. start pipelines in the downstream project, otherwise the downstream pipeline fails to start.

My challenge is how to pass variables from child to parent pipeline and how the parent pipeline can pass these variables to a downstream pipeline, that it describes in another GitLab project. Variables can be set at the pipeline level with a global variables section. to the right of the pipeline graph. Self-hosted GitLab administrators can use instance variables to expose common shared values, although this could cause unintentional information exposure if not carefully managed. A second way solves this disadvantage. Next, a user can pass the path to the file to any applications that need it. At the top level, its globally available and all jobs can use it.
