Workflow syntax

The workflow file is written in YAML. In the YAML workflow file, you can use expression syntax to evaluate contextual information, literals, operators, and functions. Contextual information includes workflow, environment variables, secrets, and the events that triggered the workflow. When you use run in a workflow step to run shell commands, you can use specific workflow command syntax to set environment variables, set output parameters for subsequent steps, and set error or debug messages.
