The GitLab documentation describes very well how to pass variables to a downstream pipeline. But there's a problem! When authenticating with the API, you can use: A trigger token to trigger a branch or tag pipeline. You'll need the numeric project ID -- that's $CI_PROJECT_ID, if your script is running in Gitlab CI. stage: build To access environment variables in Bash, sh, and similar shells, prefix the If there are other ways than the ones I've tried, I'm very happy to hear them. and kubectl A CI/CD job token to trigger a multi-project pipeline.

When you trigger a downstream pipeline with the trigger keyword, Variables set in the GitLab UI by default are not available to When you have another or better approach how to solve this described problem, let me know and please write a comment. For example: You can use the CI/CD job token (CI_JOB_TOKEN) with the When other users try to run a pipeline with overridden variables, they receive the There are so many places that variables can be defined that it can be tricky to work out where a value should be located. Config generation script You trigger a child pipeline configuration file from a parent by including it with the include key as a parameter to the trigger key. if a pipeline fails for the main branch, its common to say that main is broken. runner for testing, the path separator for the trigger job is /. for manually-triggered pipelines. for creating a new release via the Gitlab API. In the next build steps the variable VERSION is available and contains the correct version value. with the CI/CD configuration in that file. Next use the Variables table to define variables to add to this pipeline run. There are several options available depending on where you want values to be surfaced and how regularly youll want to change them. Okey so if it erase then you need to have "needs" option or start using stages like that: Gitlab CI/CD Pass artifacts/variables between pipelines, Pass an environment variable to another job, Gitlab ci cd removes artifact for merge requests, Use artifacts from merge request job in GitLab CI, Artifact downloads between pipelines in the same project, Access a branch or tag's latest job artifacts by URL, https://gitlab.com/gitlab-org/gitlab/-/jobs/artifacts/main/raw/review/index.html?job=coverage, Config setting: Keep artifacts from each branch's most recent succesful jobs, How a top-ranked engineering school reimagined CS curriculum (Ep.

Asking for help, clarification, or responding to other answers. So, how do you solve the pain of many teams collaborating on many inter-related services in the same repository? so quoted and unquoted variables might be parsed differently. Taking Parent-child pipelines even further, you can also dynamically generate the child configuration files from the parent pipeline. I want to have this $BUILD_VERSION in the deploy/deploying, e.g. If you have some other way of finding out in the deploying job what branch name X the building job ran on, then you can download the artefact from branch X instead of always from main like I do below.

Be careful when assigning the value of a file variable to another variable. by using needs:project and the passed variable as the ref: You can use this method to fetch artifacts from upstream merge request pipeline, Push all the files you created to a new branch, and for the pipeline result, you should see the three jobs (with one connecting to the two others) and the subsequent two children. The (important section of the) yml is then: But this the API request gets rejected with "404 Not Found". To ensure consistent behavior, you should always put variable values in single or double quotes. Whats the Difference Between a DOS and DDoS Attack?

To disable variable expansion for the variable: You can use CI/CD variables with the same name in different places, but the values James Walker is a contributor to How-To Geek DevOps. You can name the child pipeline file whatever you want, but it still needs to be valid YAML. See if GitLab 14.10 (April 2022) can help: Improved pipeline variables inheritance Previously, it was possible to pass some CI/CD variables to a downstream pipeline through a trigger job, but variables added in manual pipeline runs or by using the API could not be forwarded. The relevant parts of the docs, with links and excerpts: To browse or download the latest artifacts of a branch, use one of these two urls. For problems setting up or using this feature (depending on your GitLab Then the trigger job will read the stored artifact and use it as a configuration for the child pipeline. The method used to mask variables limits what can be included in a masked variable. You can use predefined CI/CD variables in your .gitlab-ci.yml without declaring them first. To get the best use of the features provided by Gitlab, we've been trying to set up a parent-child pipeline that would trigger the execution of some of the jobs from the project C as part of the integration process for the project P. To establish such a process, we have defined our CI configuration as the following: jenkins+gitlab+ansible() zd520pyx1314 zd520pyx1314 2023-02-21 183 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. How can I pass GitLab artifacts to another stage? pass CI_MERGE_REQUEST_REF_PATH to the downstream pipeline using variable inheritance: In the job that triggers the downstream pipeline, pass the $CI_MERGE_REQUEST_REF_PATH variable: In a job in the downstream pipeline, fetch the artifacts from the upstream pipeline A single set of common steps that feed into Multiple distinct steps, dependent on artifacts from #1, that could be nicely represented by child pipelines. For example, using rules: Set the parent pipelines trigger job to run on merge requests: Use rules to configure the child pipeline jobs to run when triggered by the parent pipeline: In child pipelines, $CI_PIPELINE_SOURCE always has a value of parent_pipeline, so: You can specify the branch to use when triggering a multi-project pipeline. From this view, you can: To retry failed and canceled jobs, select Retry (): You can recreate a downstream pipeline by retrying its corresponding trigger job. You can list all variables available to a script with the export command Alternatively, if you want the merge event to actually update the main branch with the version state, just use a source-controlled VERSION file. Using the https://docs.gitlab.com/ee/ci/yaml/#triggerforward keyword you can block variables from passing to a child pipeline (and overrides global variables) trigger_child: trigger: forward: yaml_variables: false @furkanayhan can you confirm, or do you believe we have a hidden bug somewhere?
