### Deploy 3 server and 3 agent nodes with package

Source: https://kubeclipper.io/docs/deployment-docs/ha-deploy

Deploys a cluster with 3 server and 3 agent nodes, explicitly defining the installation package.

```bash
kcctl deploy --pk-file=~/.ssh/id_rsa \
--server SERVER_IPS \
--agent AGENT_IPS \
--pkg https://oss.kubeclipper.io/release/{KC_VERSION}/kc-{GOARCH}.tar.gz
```

--------------------------------

### Deploy 3 server and 3 agent nodes without explicit package

Source: https://kubeclipper.io/docs/deployment-docs/ha-deploy

Deploys a cluster with 3 server and 3 agent nodes, defaulting to the version matching the installed kcctl.

```bash
kcctl deploy --pk-file=~/.ssh/id_rsa \
--server SERVER_IPS \
--agent AGENT_IPS
```

--------------------------------

### Deploy 3 server nodes using private key

Source: https://kubeclipper.io/docs/deployment-docs/ha-deploy

```bash
kcctl deploy --pk-file=~/.ssh/id_rsa \
--server SERVER_IPS \
--pkg https://oss.kubeclipper.io/release/{KC_VERSION}/kc-{GOARCH}.tar.gz

kcctl create cluster --master $NODE --name demo --untaint-master
```

--------------------------------

### 创建 Kubernetes 集群

Source: https://kubeclipper.io/docs/faq/kcctl-create-cluster-error
