Wait for Workflow Action

This GitHub Action waits for a specified workflow to complete before proceeding with the next steps in your workflow. It is useful when you have dependent workflows and want to ensure that one completes successfully before continuing with the next. For example, you might want to ensure that a build or test workflow finishes successfully before starting a deployment workflow.

Inputs

Input	Description	Required	Default
GITHUB_TOKEN	GitHub token to access the repository and its APIs	Yes
workflow_id	ID of the workflow to wait for	No
run_id	If provided will wait for workflow run with specified id	No
max_wait_minutes	Maximum time script will wait to workflow run to be found in minutes	No	5
interval	Interval in seconds which will be used for GitHub API calls	No	10
timeout	Maximum time script will wait to workflow run to be finished	No	30
org_name	Organization name where the repository is located	Yes
repo_name	Repository name to monitor for the workflow run	Yes
ref	Branch reference to watch for the workflow run	No

How It Works

This action performs the following steps:

1. Retrieves the current time in ISO 8601 format.
2. Loops until the specified workflow is triggered:
   • Sends a request to the GitHub API to get the list of workflow runs for the specified workflow ID.
   • Filters the list of workflow runs based on the provided ref (branch) and the run creation time.
   • Checks if the maximum waiting time has been reached. If so, exits with an error message.
   • Sleeps for 30 seconds before checking again if the workflow has been triggered.
3. Once the workflow is triggered, loops until the workflow run is completed:
   • Sends a request to the GitHub API to get the status of the specified workflow run.
   • Checks if the status is "completed". If so, proceeds to the next step.
   • Sleeps for 30 seconds before checking again if the workflow has been completed.
4. When the workflow run is completed, checks its conclusion:
   • If the conclusion is "success", the action exits successfully.
   • If the conclusion is anything other than "success", the action exits with an error message.

Usage

To use this action, add it to your workflow file with the appropriate inputs:

- name: Wait for Workflow Action
  uses: kamilchodola/[email protected]
  with:
    GITHUB_TOKEN: ${{ secrets.REPOSITORY_DISPATCH_TOKEN }}
    workflow_id: 'workflow_name.yml'
    max_wait_minutes: '3'
    interval: '5'
    timeout: '60'
    org_name: 'your-organization'
    repo_name: 'your-repository'
    ref: '${{ github.ref }}'

In case, you already have run_id, you can pass it this way:

- name: Wait for Workflow Action
  uses: kamilchodola/[email protected]
  with:
    GITHUB_TOKEN: ${{ secrets.REPOSITORY_DISPATCH_TOKEN }}
    workflow_id: 'workflow_name.yml'
    run_id: '123123'
    org_name: 'your-organization'
    repo_name: 'your-repository'
    ref: '${{ github.ref }}'

Notes

• If the ref input is not provided or is left empty, the action will use the current github.ref as the branch reference. This is useful when you want to wait for a workflow run on the same branch that triggered the current workflow.
• The maximum wait time is specified in minutes. The default value is 3 minutes if not provided. If the workflow has not been triggered or completed after the specified maximum wait time, the action will exit with an error. You can increase this value if you expect the workflow to take longer to start or complete. Keep in mind that the GitHub Actions runner has a default timeout of 6 hours for a job, so ensure your wait time falls within this limit.
