Consequently it only works for values that meet specific formatting requirements. You can only view child pipelines on It explains how multiple levels of group CI/CD variables You can use include:projectin a trigger job to trigger child pipelines with a configuration file in a different project: microservice_a: trigger: include: -project:'my-group/my-pipeline-library' ref:'main' file:'/path/to/child-pipeline.yml' Combine multiple child pipeline configuration files The order of precedence for variables is (from highest to lowest): In this example, job1 outputs The variable is 'secure' because variables defined in jobs To make variables more secure, environment variables must be surrounded by quotes to expand properly: To access CI/CD variables in Windows Batch, surround the variable with %: You can also surround the variable with ! or have them prefilled in manual pipelines. To access environment variables in Bash, sh, and similar shells, prefix the If the job/variable/project/branch of the upstream pipeline changes its name, the downstream pipeline doesn't recognize this change automatically, and it couldn't work anymore as expected. 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. control job behavior in downstream pipelines. all variables and other secrets available to the job.
