Execute a workflow

Executing a workflow runs the current workflow definition associated with the workflow.

You can pass runtime arguments in a workflow execution request and access those arguments using a workflow variable. For more information, see Pass runtime arguments in an execution request.

After a workflow execution completes, its history and results are retained for a limited time. For more information, see Quotas and limits.

Before you begin

Security constraints defined by your organization might prevent you from completing the following steps. For troubleshooting information, see Develop applications in a constrained Google Cloud environment.

Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

Roles required to select or create a project

Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
Create a project: To create a project, you need the Project Creator role (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.

If a workflow accesses other Google Cloud resources, make sure it is associated with a service account that has the correct permissions to do so. To learn what service account is associated with an existing workflow, see Verify a workflow's associated service account.
Note that to create a resource and attach a service account, you need permissions to create that resource and to impersonate the service account that you will attach to the resource. For more information, see Service account permissions.
Deploy a workflow using the Google Cloud console or the Google Cloud CLI.

Note: To send logs to Cloud Logging, make sure the service account executing the workflow has been granted a role that includes the logging.logEntries.create permission (for example, the Logs Writer role).
