Manually trigger Github Action Workflow from CLI

Motivation: the Github UI by default won't let you specify tags as input when triggering a workflow enabled with the on: workflow_dispatch event type.

Get Workflow ID

gh workflow list
Verify Docker Login      active  9450050

Trigger Workflow via API

Chose a valid tag which has the workflow definition (file) included.

⚠️ Note: It is not sufficient that the workflow just exists in the specified tag. The workflow version in that tag MUST have a on: workflow_dispatch trigger defined, otherwise "Workflow does not have 'workflow_dispatch' trigger" is returned.

echo '{"ref":"refs/tags/v0.3.1"}' | gh api repos/{owner}/{repo}/actions/workflows/9450050/dispatches --input -

On success the result will be 204, i.e. empty content. See API definition for details.

Note that the short version to specify a tag also works, e.g. '{"ref":"v0.3.1"}'
