You can access a workflow's environment information using built-in environment variables. Built-in environment variables require no declaration and are available in every workflow execution.
User-defined environment variables are also supported.
List of built-in environment variables
You can use the following built-in environment variables:
GOOGLE_CLOUD_LOCATION
: The location of the workflow.GOOGLE_CLOUD_PROJECT_ID
: The project identifier of the workflow.GOOGLE_CLOUD_PROJECT_NUMBER
: The project number of the workflow.GOOGLE_CLOUD_SERVICE_ACCOUNT_NAME
: The name of the workflow execution's service account.GOOGLE_CLOUD_WORKFLOW_EXECUTION_ID
: The identifier of the workflow execution.GOOGLE_CLOUD_WORKFLOW_ID
: The identifier of the workflow.GOOGLE_CLOUD_WORKFLOW_REVISION_ID
: The identifier of the workflow revision.
Access built-in environment variables
To access an environment variable, make a call to the sys.get_env()
function
in an expression, passing the name of the environment variable as a parameter.
The name of the environment variable must be passed as a string.
For example, the following step assigns the value of the environment variable
GOOGLE_CLOUD_PROJECT_ID
to a workflow variable called projectID
:
- getProjectID: assign: - projectID: ${sys.get_env("GOOGLE_CLOUD_PROJECT_ID")}
