--etcd-init-image string etcd init container image (default "docker.io/alpine:3.14.3")
--etcd-replicas int32 etcd replica set, cluster 3,5...singular (default 1)
--etcd-storage-mode string etcd data storage mode(emptyDir,hostPath,PVC). value is PVC, specify --storage-classes-name;value is hostPath,--etcd-replicas is 1 (default "emptyDir")
--etcd-storage-size string etcd data path,valid in pvc mode. (default "1Gi")
-h, --help help for install

Examples
kaadm install --master=192.168.1.2 --etcd-replicas 3
- 192.168.1.2 is karmada apiserver node,kaadm finds node by IP and adds
karmada.io/master=tag,Binding by label. etcd-replicas=3Is a 3-node etcd cluster.
If nothing happens, print the following information.

| Push mode |
| |
| Step 1: Member kubernetes join karmada control plane |
| |
| (In karmada)~# cat ~/.kube/config | grep current-context | sed 's/: /\n/g'| sed '1d' #MEMBER_CLUSTER_NAME |
| (In karmada)~# kubectl-karmada --kubeconfig /var/lib/karmada/karmada-apiserver.config join ${MEMBER_CLUSTER_NAME} --cluster-kubeconfig=$HOME/.kube/config |
| |
| Step 2: Create member kubernetes kubeconfig secret |
| |
| (In member kubernetes)~# kubectl create ns karmada-system |
| (In member kubernetes)~# kubectl create secret generic ${MEMBER_CLUSTER_NAME}-kubeconfig --from-file=${MEMBER_CLUSTER_NAME}-kubeconfig=$HOME/.kube/config -n karmada-system |
| |
| Step 3: Create karmada scheduler estimator |
| |
| (In member kubernetes)~# sed -i "s/{{member_cluster_name}}/${MEMBER_CLUSTER_NAME}/g" /var/lib/karmada/karmada-scheduler-estimator.yaml |
| (In member kubernetes)~# kubectl create -f /var/lib/karmada/karmada-scheduler-estimator.yaml |
| |
| Step 4: Show members of karmada |
| |
| (In karmada)~# kubectl --kubeconfig /var/lib/karmada/karmada-apiserver.config get clusters |

| Pull mode |
| |
| Step 1: Send karmada kubeconfig and karmada-agent.yaml to member kubernetes |
| |
| (In karmada)~# scp /var/lib/karmada/karmada-apiserver.config /var/lib/karmada/karmada-agent.yaml {member kubernetes}:~ |
| |
| Step 2: Create karmada kubeconfig secret |
| Notice: |
| Cross-network, need to change the config server address. |
| |
| (In member kubernetes)~# kubectl create ns karmada-system |
| (In member kubernetes)~# kubectl create secret generic karmada-kubeconfig --from-file=karmada-kubeconfig=/root/karmada-apiserver.config -n karmada-system |
| |
| Step 3: Create karmada agent |
| |
| (In member kubernetes)~# MEMBER_CLUSTER_NAME="demo" |
| (In member kubernetes)~# sed -i "s/{member_cluster_name}/${MEMBER_CLUSTER_NAME}/g" karmada-agent.yaml |
| (In member kubernetes)~# kubectl create -f karmada-agent.yaml |
| |
| Step 4: Show members of karmada |
| |
| (In karmada)~# kubectl --kubeconfig /var/lib/karmada/karmada-apiserver.config get clusters |
