gh workflow run

 ✗ gh help workflow run
Create a workflow_dispatch event for a given workflow.

This command will trigger GitHub Actions to run a given workflow file.  
The given workflow file must support a workflow_dispatch 'on' 
trigger in order to be run in this way.

If the workflow file supports inputs, they can be specified in a few ways:

- Interactively
- via -f or -F flags
- As JSON, via STDIN
 

USAGE
  gh workflow run [<workflow-id> | <workflow-name>] [flags]

FLAGS
  -F, --field key=value       Add a string parameter in key=value format, respecting @ syntax
      --json                  Read workflow inputs as JSON via STDIN
  -f, --raw-field key=value   Add a string parameter in key=value format
  -r, --ref string            The branch or tag name which contains the version of the workflow file you'd like to run

INHERITED FLAGS
      --help                     Show help for command
  -R, --repo [HOST/]OWNER/REPO   Select another repository using the [HOST/]OWNER/REPO format

EXAMPLES
  # Have gh prompt you for what workflow you'd like to run and interactively collect inputs
  $ gh workflow run
  
  # Run the workflow file 'triage.yml' at the remote's default branch
  $ gh workflow run triage.yml
  
  # Run the workflow file 'triage.yml' at a specified ref
  $ gh workflow run triage.yml --ref my-branch
  
  # Run the workflow file 'triage.yml' with command line inputs
  $ gh workflow run triage.yml -f name=scully -f greeting=hello
  
  # Run the workflow file 'triage.yml' with JSON via standard input
  $ echo '{"name":"scully", "greeting":"hello"}' | gh workflow run triage.yml --json

Running Manually a Workflow

Set this workflow file:

➜  use-hello-world-javascript-action git:(master) cat .github/workflows/manual.yml

name: Manually triggered workflow
on:
  workflow_dispatch:
    inputs:
      name:
        description: 'Person to greet'
        required: true
        default: 'Mona the Octocat'
      home:
        description: 'location'
        required: false
        default: 'The Octoverse'

jobs:
  say_hello:
    runs-on: ubuntu-latest
    steps:
    - run: |
        echo "Hello $!"
        echo "- in $!"

This example defines the name and home inputs and prints them using the github.event.inputs.name and github.event.inputs.home contexts. If a home isn’t provided, the default value 'The Octoverse' is printed.

You can use the GitHub API to trigger a webhook event called repository_dispatch when you want to trigger a workflow for activity that happens outside of GitHub.

For more information, see “Create a repository dispatch event.”

To trigger the custom repository_dispatch webhook event, you must send a POST request to a GitHub API endpoint and provide an event_type name to describe the activity type. To trigger a workflow run, you must also configure your workflow to use the repository_dispatch event.

Now, using gh we can run it manually:

➜  use-hello-world-javascript-action git:(master) gh workflow run manual.yml -f name="PL at ULL" -f home="La Laguna"
✓ Created workflow_dispatch event for manual.yml at master

To see runs for this workflow, try: gh run list --workflow=manual.yml

➜  use-hello-world-javascript-action git:(master) gh run list --workflow=manual.yml
✓  .github  Manually triggered workflow  master  workflow_dispatch  758223539

For details on a run, try: gh run view <run-id>

➜  use-hello-world-javascript-action git:(master) gh run view 758223539
