When other users try to run a pipeline with overridden variables, they receive the Not the answer you're looking for? 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. Does anyone know a way how to get this to work? For now, I've used shell as well as Python. The child pipeline config files are the same as those in the non-dynamic example above. When restricted, only users with In pipeline mini graphs, the downstream pipeline predefined CI/CD variable, is available in the downstream pipeline. Exchange artifacts between parent and child pipelines - GitLab CI/CD (Doesn't matter if build.env is in the .gitignore or not, tested both). Variables can be managed at any time by returning to the settings screen of the scope theyre set in. to a downstream pipeline, as they are not available in trigger jobs. CI/CD variables are a type of environment variable. Settings > CI/CD > Variables section. information about the job, pipeline, and other values you might need when the pipeline GitLab CI/CD makes a set of predefined CI/CD variables available for use in pipeline configuration and job scripts. their own child pipelines. Breaking down CI/CD complexity with parent-child and multi - GitLab You can reference them within your .gitlab-ci.yml file as standard environment variables: You can escape the $ character using the $$VARIABLE syntax: This example would cause $EXAMPLE_VARIABLE to be logged, instead of the value of the EXAMPLE_VARIABLE variable as shown above. GitLab server and visible in job logs. 565), Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. control job behavior in downstream pipelines. can overwrite each other. So my question is: How do I pass the $BUILD_VERSION (and other data) from staging/building to deploy/deploying? This exposes the values of all available I don't want to resort to scripts instead of trigger. all variables containing sensitive information should be masked in job logs. with debug output before you make logs public again. During working with GitLab multi-project pipelines and parent-child pipelines, I have encountered the problem how to pass variables through these pipelines. the URL of a database saved in a DATABASE_URL variable. Hover behavior for pipeline cards introduced in GitLab 13.2. You can use variables in job scripts with the standard formatting for each environments Downstream pipelines | GitLab search the docs.

To create a CI/CD variable in the .gitlab-ci.yml file, define the variable and Create a trigger token where id is the merge request ID. Since the parent pipeline in .gitlab-ci.yml and the child pipeline run as normal pipelines, they can have their own behaviors and sequencing in relation to triggers. GitLab CIs Variables system lets you inject data into your CI job environments. for delayed expansion. Let's start, how to publish the variable that are defined in a child pipeline. Have not been run from inside a CI container, The initial GraphQL API request script is untested, The final command to download and extract the archive is untested.

To have no environment variables from a dotenv artifact: You cannot create a CI/CD variable that is an array of values, but you Currently, when using this pattern, developers all use the same .gitlab-ci.yml file to trigger different automated processes for different application components, likely causing merge conflicts, and productivity slowdown, while teams wait for "their part" of a pipeline to run and complete. Before you enable debug logging, make sure only team members Are independent, so there are no nesting limits. Variables are supported at the instance, group, project, and pipeline level, giving you flexibility when setting fallback values, defaults, and overrides. To disable variable expansion for the variable: You can use CI/CD variables with the same name in different places, but the values The Windows build child pipeline (.win-gitlab-ci.yml) has the following configuration, and unless you want to trigger a further child pipeline, it follows standard a configuration format: Don't forget the -y argument as part of the apt-get install command, or your jobs will be stuck waiting for user input. Creating a child pipeline. You cannot use this method to forward job-level persisted variables The downstream pipeline fails to create with the error: downstream pipeline can not be created, Ref is ambiguous. You can name the child pipeline file whatever you want, but it still needs to be valid YAML. The precedence order is relatively complex but can be summarized as the following: You can always run a pipeline with a specific variable value by using manual execution. all jobs in a pipeline, including trigger jobs, inherit global variables. then in script do export/copy to the file, for example: To make it working, just try to solve passing problems, keep dependencies and to keep artifacts just use "needs", avoid clearing artifacts within job. all variables and other secrets available to the job. For more information, see the Cross-project Pipeline Triggering and Visualization demo at There are several options available depending on where you want values to be surfaced and how regularly youll want to change them. I feel like this is the way it should work. As applications and their repository structures grow in complexity, a repository .gitlab-ci.yml file becomes difficult to manage, collaborate on, and see benefit from. _jenkins+gitlab+ansible() You can always run a pipeline with a specific variable value by using manual execution.

Since we launched in 2006, our articles have been read billions of times. 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. I tried to use $CI_COMMIT_REF_NAME. use $$ instead: Expanded variables treat values with the $ character as a reference to another variable. Variable type variables: Project, group, and instance CI/CD variables are variable type by default, but can But in the last step I want to pass this variable to a downstream pipeline: trigger-deployment: stage: trigger_deploy variables: VERSION: $VERSION trigger: project: my/project This doesn't work. valid secrets file. So how will I be able to get values from a child pipeline ? Thanks in advance. Asking for help, clarification, or responding to other answers. Then print either the job id or the artifact archive url. Variables are available within the jobs environment.

Also ideally, somebody will try out the code above and leave a comment whether they get it to work. Code pushed to the .gitlab-ci.yml file could compromise your variables. Once I'm messing with Gitlab again I'll try it out. You can use debug logging to help troubleshoot problems with pipeline configuration For example, VAR1: 012345 Malicious scripts like in malicious-job must be caught during the review process. Since commit SHAs are not supported, $CI_COMMIT_BEFORE_SHA or $CI_COMMIT_SHA do not work either. accessing variable values. is triggered or running. GitLab CI/CD is a powerful continuous integration tool that works not only per project, but also across projects with multi-project pipelines.

Passing artifacts from downstream pipelines to upstream ones may be implemented later according to this issue: https://gitlab.com/gitlab-org/gitlab/-/issues/285100. by using strategy: depend: After you trigger a multi-project pipeline, the downstream pipeline displays MIP Model with relaxed integer constraints takes longer to solve than normal model, why? by default can only access variables saved in the .gitlab-ci.yml file. GitLab CI/CD makes a set of predefined CI/CD variables Limiting that value to only the pipelines that actually need it (like deployment jobs running against your protected release branch) lowers the risk of accidental leakage. 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. To make a UI-defined variable available in a service container, For example, Splitting complex pipelines into multiple pipelines with a parent-child relationship can improve performance by allowing child pipelines to run concurrently. But since I need the artifacts in a non-merge-request pipeline, I cannot use the suggested CI_MERGE_REQUEST_REF_PATH. Trigger pipelines by using the API | GitLab The CI/CD masking configuration is not passed to the Gitlab CI/CD Pass artifacts/variables between pipelines 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. malicious code can compromise both masked and protected variables. 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 What if another MR was merged in between? GitLab Pipeline tag stopped triggering stage marked only:tags, Trigger another job as a part of job in Gitlab CI Pipeline, Implement Multi-project gitlab pipeline with common deploy and test stages, whitelist some inherrited variables (but not all) in gitlab multi-project pipeline, Gitlab CI/CD - re-use old variable in child pipeline without being triggered by parent pipeline, GitLab trigger a child pipeline without retriggering the parent pipeline. Be careful when assigning the value of a file variable to another variable. Gitlab child pipeline with dynamic configuration in 5 minutes because the downstream pipeline attempts to fetch artifacts from the latest branch pipeline. Protected variables are ideal in circumstances where youre exposing a sensitive value such as a deployment key that wont be used in every pipeline. Taking Parent-child pipelines even further, you can also dynamically generate the child configuration files from the parent pipeline. Retry or cancel child pipelines You can retry or cancel child pipelines: In the main graph view. In this release weve added a new trigger:forward keyword to control what things you forward to downstream parent-child pipelines or multi-project pipelines, which provides a flexible way to handle variable inheritance in downstream pipelines. Exemple: My CHILD pipeline create a staging environment with dynamic URL. if a pipeline fails for the main branch, its common to say that main is broken.
