You can list all variables available to a script with the export command can be combined with environment-scoped project variables for complex configuration You can find the whole example on GitLab. called multi-project pipelines. you can set the trigger job to show the downstream pipelines status Not the answer you're looking for? Consequently it only works for values that meet specific formatting requirements. Variables listed here will be created for the job if they dont already exist; otherwise, theyll override the value set at the project-level or higher. GitLab CI/CD makes a set of predefined CI/CD variables Save the predefined variable as a new job variable in the trigger Any unintentional echo $SECRET_VALUE will be cleaned up, reducing the risk of a user seeing a sensitive token value as they inspect the job logs using the GitLab web UI. Passing negative parameters to a wolframscript, What "benchmarks" means in "what are benchmarks for?". Define CI/CD variables in the UI: Alternatively, these variables can be added by using the API: By default, pipelines from forked projects cant access the CI/CD variables available to the parent project. Let "building" happen all the time, and limit "deploy" to main branch. I copied the, Sorry, missed the part where you were trying to skip the, Thank you for your answer. Still, it does not work. You cannot use this method to forward job-level persisted variables Did the Golden Gate Bridge 'flatten' under the weight of 300,000 people in 1987?

See if GitLab 14.10 (April 2022) can help: 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. To access environment variables, use the syntax for your runner executors shell. which variables take precedence. start pipelines in the downstream project, otherwise the downstream pipeline fails to start.
