  4. Create a file called values.yaml file containing the following:

Container runner configuration example

Once you have installed the container runner within your cluster, create and trigger a CircleCI job that uses the Docker executor to validate the installation. The fields you must set for a specific job to run using your container runners are:

  • image:

  • resource_class: <namespace>/<resource-class>

Simple example of how you could set up a job (cimg/base:2021.11 is a commonly used CircleCI Docker image):

version: 2.1

      - image: cimg/base:2021.11
    resource_class: <namespace>/<resource-class>
      - checkout
      - run: echo "Hi I'm on Runners!"

      - build
