Make sure you have the following set up before you begin this tutorial:

  • Github account: This tutorial clones a codebase from a Github repo. You will need a Github account so Harness can connect to Github.
  • Docker Hub account and repo: You will need to push and pull the image you build to Docker Hub. You can use any repo you want, or create a new one for this tutorial.
  • Kubernetes cluster for Harness Delegate and build farm: You'll need a Kubernetes cluster for Harness to use for the Harness Delegate and as a build farm. Ensure you have a cluster that meets the following requirements:
  • Number of pods: 3 (two pods for the Harness Delegate, the remaining pod for the build farm).
  • Machine type: 4vCPU
  • Memory: 16GB RAM. The build farm and Delegate requirements are low but the remaining memory is for Kubernetes, the Docker container, and other default services.
  • Networking: Outbound HTTPS for the Harness connection, and to connect to Docker Hub. Allow TCP port 22 for SSH.
  • Namespace: When you install the Harness Delegate, it will create the harness-delegate namespace. You'll use the same namespace for the build farm.
  • A Kubernetes service account with permission to create entities in the target namespace is required. The set of permissions should include list, get, create, and delete permissions. In general, the cluster-admin permission or namespace admin permission is enough. For more information, see User-Facing Roles from Kubernetes.
