“Github Actions” supplies a special event for workflows that can be triggered manually from the web interface. This event is
workflow_dispatch. By default, it has only one input parameter:
git branch that must be a context for the workflow execution. But the set of input parameters can be extended with custom ones.
The syntax is following:
on: workflow_dispatch: inputs: test-run: description: 'Test (y/n)?' required: true default: 'y'
And later on, the values of the inputs can be used as conditions for workflow steps:
jobs: build: steps: - name: Yes branch if: github.event.inputs.test-run == 'y' run: echo "Test = Y"
The sample workflow can be found on GitHub.
