Github Event workflow_dispatch #

Github Action Trigger #

source

Note: This event will only trigger a workflow run if the workflow file is on the default branch.

To enable a workflow to be triggered manually, you need to configure the workflow_dispatch event. You can manually trigger a workflow run using the GitHub API, GitHub CLI, or GitHub browser interface. For more information, see “Manually running a workflow.”

on: workflow_dispatch

Providing inputs #

You can configure custom-defined input properties, default input values, and required inputs for the event directly in your workflow. When you trigger the event, you can provide the ref and any inputs. When the workflow runs, you can access the input values in the inputs context. For more information, see “Contexts.”

Notes:

• The workflow will also receive the inputs in the github.event.inputs context. The information in the inputs context and github.event.inputs context is identical except that the inputs context preserves Boolean values as Booleans instead of converting them to strings. The choice type resolves to a string and is a single selectable option.
• The maximum number of top-level properties for inputs is 10.
• The maximum payload for inputs is 65,535 characters.

This example defines inputs called logLevel, tags, and environment. You pass values for these inputs to the workflow when you run it. This workflow then prints the values to the log, using the inputs.logLevel, inputs.tags, and inputs.environment context properties.

    inputs:
      logLevel:
        description: 'Log level'
        required: true
        default: 'warning'
        type: choice
        options:
        - info
        - warning
        - debug
      tags:
        description: 'Test scenario tags'
        required: false
        type: boolean
      environment:
        description: 'Environment to run tests against'
        type: environment
        required: true

jobs:
  log-the-inputs:
    runs-on: ubuntu-latest
    steps:
      - run: |
          echo "Log level: $LEVEL"
          echo "Tags: $TAGS"
          echo "Environment: $ENVIRONMENT"          
        env:
          LEVEL: ${{ inputs.logLevel }}
          TAGS: ${{ inputs.tags }}
          ENVIRONMENT: ${{ inputs.environment }}

If you run this workflow from a browser you must enter values for the required inputs manually before the workflow will run.

You can also pass inputs when you run a workflow from a script, or by using GitHub CLI. For example:

gh workflow run run-tests.yml -f logLevel=warning -f tags=false -f environment=staging

For more information, see the GitHub CLI information in “Manually running a workflow.”

Event Payload #

source

This event occurs when a GitHub Actions workflow is manually triggered. For more information, see "Manually running a workflow."

For activity relating to workflow runs, use the workflow_run event.

To subscribe to this event, a GitHub App must have at least read-level access for the "Contents" repository permission.
