Karmada hack GuideLines

This document describes how you can use the scripts from the hack directory and gives a brief introduction and explanation of these scripts.

Scripts in this directory are mainly for the purpose which improves development efficiency and ensures development quality.

Key scripts

For end-user

• local-up-karmada.sh This script will quickly set up a local development environment based on the current codebase.

• remote-up-karmada.sh This script will install Karmada to a standalone K8s cluster, this cluster may be real, remote , and even for production. It is worth noting for the connectivity from your client to Karmada API server, it will create a load balancer service with an external IP by default, if your want to customize this service, you may add the annotations at the metadata part of service karmada-apiserver in ../artifacts/deploy/karmada-apiserver.yaml before the installing. The following is an example.

  # If you want to use a internal IP in public cloud you need to fill the following annotation, 
  # Fot the more annotation settings please read your public cloud docs
  annotations: 
    # Aliyun cloud
    #service.beta.kubernetes.io/alibaba-cloud-loadbalancer-address-type: "intranet"
    # Huawei cloud
    #kubernetes.io/elb.autocreate: '{"type":"inner"}'
    # Tencent cloud (you need to replace words 'xxxxxxxx')
    #service.kubernetes.io/qcloud-loadbalancer-internal-subnetid: subnet-xxxxxxxx

• deploy-karmada-agent.sh This script will install Karmada Agent to the specific cluster.

• undeploy-karmada.sh This script will uninstall Karmada from the specific cluster. It will uninstall Karmada from your local environment default. If you installed Karmada with remote-up-karmada.sh, please use it like this: hack/undeploy-karmada.sh <KUBECONFIG> <CONTEXT_NAME>, the same parameters as you input at the installing step.

For CI pipeline

• karmada-bootstrap.sh This script will quickly pull up a local Karmada environment too, what is different from local-up-karmada.sh is it will pull up member clusters. This is usually for testing, of course, you may also use it for your local environment.

• run-e2e.sh This script runs e2e test against on Karmada control plane. You should prepare your environment in advance with karmada-bootstrap.sh.

Some internal scripts

These scripts are not intended used by end-users, just for the development

• deploy-karmada.sh Underlying common implementation for local-up-karmada.sh, remote-up-karmada.sh and karmada-bootstrap.sh

• util.sh All util functions.
