In subsequent tasks, you can use the $(FOO) syntax to have Azure Pipelines replace the variable with some value.Set the value with the command echo "#vsosome value".In a script task, you need to print a special value to STDOUT that will be captured by Azure Pipelines to set the variable.įor example, to pass the variable FOO between scripts: Passing variables between tasks in the same job The work below is based on the official documentation, adding some examples and explaining how to pass variables between stages. The same concepts would apply to developers working with PowerShell or Batch scripts, although the syntax of the commands will be slightly different. I’ll focus on pipelines running on Linux, and all examples show bash scripts. The examples below are about using multi-stage pipelines within YAML documents. One recurrent question is: how do you pass variables around tasks? While passing variables from a step to another within the same job is relatively easy, sharing state and variables with tasks in other jobs or even stages isn’t immediate. This is very powerful, as it lets developers define their pipelines to continuously build and deploy apps, using a declarative syntax, and storing the YAML document in the same repo as their code, versioned. They have recently enabled support for multi-stage pipelines defined in YAML documents, allowing the creation of both build and release (CI and CD) pipelines, in a single azure-pipelines.yaml file. This is a quick reference on passing variables between multiple tasks in Azure Pipelines, a popular CI/CD platform. Passing variables between steps, jobs, and stages: explained
