The value of the variable must: Different versions of GitLab Runner have different masking limitations: You can configure a project, group, or instance CI/CD variable to be available If you use a public project to trigger downstream pipelines in a private project, Currently with Gitlab CI there's no way to provide a file to use as environment variables, at least not in the way you stated. Variables defined in .gitlab-ci.yml files can sometimes be used in different ways to those set within the GitLab UI or API. How can I pass GitLab artifacts to another stage? The building job in staging builds the app and creates a "Review App" (no separate build stage for simplicity). paths: choose the ref of the downstream pipeline, and pass CI/CD variables to it. The Managing the Complex Configuration Data Management Monster Using GitLab P.s. Consequently it only works for values that meet specific formatting requirements. For an overview, see Create child pipelines using dynamically generated configurations. A second way solves this disadvantage.

See the trigger: keyword documentation for full details on how to include the child pipeline configuration. Also the yml file shown below is heavily inspired by this example. all variables containing sensitive information should be masked in job logs. The setup is a simple one but hopefully illustrates what is possible. A downstream pipeline is any GitLab CI/CD pipeline triggered by another pipeline. Run a command that saves the value of the variable in a file. You also have to add a reference to the project that contains the parent and the child pipeline.

To pass a job-created environment variable to other jobs: Variables from dotenv reports take precedence over More details the script of the job and cant be used to configure it, for example with rules or artifact:paths. paths: It also exposes all variables and secrets If you run a merge request pipeline in the parent project for a merge request from a fork, For example, you can store multiple values separated by a space in a variable, We select and review products independently. You can pass CI/CD variables to a downstream pipeline with Malicious scripts like in malicious-job must be caught during the review process. To trigger a child pipeline from a dynamically generated configuration file: Generate the configuration file in a job and save it as an artifact: Configure the trigger job to run after the job that generated the configuration file, be accidentally exposed in a job log, or maliciously sent to a third party server. 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.

In this example, a job named pdf calls the xelatex command to build a PDF file from the LaTeX source file, mycv.tex.. available to the job. This technique can be very powerful for generating pipelines You can stop global CI/CD variables from reaching the downstream pipeline with I tried to use $CI_COMMIT_REF_NAME. Alternatively, if you want the merge event to actually update the main branch with the version state, just use a source-controlled VERSION file. You can use the variables keyword to pass CI/CD variables to a downstream pipeline. Multi-project pipelines are useful for larger products that require cross-project inter-dependencies, such as those adopting a microservices architecture. The following code illustrates configuring a bridge job to trigger a downstream pipeline: //job1 is a job in the upstream project deploy: stage: Deploy script: this is my script //job2 is a bridge .

I also tried this. Once I'm messing with Gitlab again I'll try it out. dotenv report and it can access BUILD_VERSION in the script: With multi-project pipelines, the trigger job fails and does not create the downstream pipeline if: If the parent pipeline is a merge request pipeline, start pipelines in the downstream project, otherwise the downstream pipeline fails to start. The method used to mask variables limits what can be included in a masked variable. Why the obscure but specific description of Jane Doe II in the original complaint for Westenbroek v. Kappa Kappa Gamma Fraternity? Another useful pattern to use for parent-child pipelines is a rules key to trigger a child pipeline under certain conditions. Variables passed to child pipelines are currently 5th - Inherited variables. For your case, assuming the 'building' and 'deploying' jobs both run on the main branch, you can hopefully pass the artifact like so.
