machine: true -
resource_class: <namespace>/<resource-class>
Simple example of how you could set up a job:
version: 2.1
workflows:
build-workflow:
jobs:
- runner
jobs:
runner:
machine: true
resource_class: <namespace>/<resource-class>
steps:
- run: echo "Hi I'm on Runners!"The job will then execute using your self-hosted runner when you push the .circleci/config.yml to your VCS provider.
