## README

# 环境要求

- Ubuntu 18
- 主机可以翻墙

# 使用

## master 节点部署

```shell
curl https://gitee.com/huang_juan/k8s-deploy-shell/raw/master/master.sh | sh
```

## worker 节点部署

- 部署 `kubeadm`

```shell
curl https://gitee.com/huang_juan/k8s-deploy-shell/raw/master/worker.sh | sh
```

- 在 master 节点执行下面命令，获取到 token 和 ca_hash

```shell
kubeadm token create
master_ip=$(ifconfig | grep eth0 -A 1 | grep inet | awk '{print $2}')
token=$(kubeadm token list | grep -v TOKEN | awk '{print $1}' | head -n 1)
ca_hash=$(openssl x509 -pubkey -in /etc/kubernetes/pki/ca.crt | openssl rsa -pubin -outform der 2>/dev/null | openssl dgst -sha256 -hex | sed 's/^.* //')

echo kubeadm join $master_ip:6443 --token $token --discovery-token-ca-cert-hash sha256:$ca_hash
```

- 将 worker 节点加入 k8s cluster，先在 master 节点上的生成命令，复制到 worker 节点执行

```shell
kubeadm join $master_ip:6443 --token $token --discovery-token-ca-cert-hash sha256:$ca_hash
```

- 在 worker 节点上配置 kubectl

```shell
mkdir -p $HOME/.kube
scp root@$master_ip:/etc/kubernetes/admin.conf $HOME/.kube/config
chown $(id -u):$(id -g) $HOME/.kube/config
```

## 安装 Metrics API

```shell
kubectl apply -f https://gitee.com/huang_juan/k8s-deploy-shell/raw/master/metrics-api.yaml
```
