Rancher部署k8s集群

rancher部署k8s集群

前提条件：

docker已经安装

一、Docker快速安装

sudo docker run -d --name=rancher2 --privileged --restart=unless-stopped -p 9080:80 -p 9443:443 rancher/rancher:v2.5.11

剩下步骤按要求一步一步来

二、部署私有网络下的LB开源方案metallb

在kubectl终端下执行一下命令

# 安装metallb.yaml
kubectl apply -f https://gitee.com/cyneck/metallb/raw/master/manifests/metallb.yaml

# 查看metallb-system命名空间是否生成
kubectl get all -n metallb-system

配置负载均衡私有网络下的地址池

kubectl apply -f - << EOF

apiVersion: v1
kind: ConfigMap
metadata:
  namespace: metallb-system
  name: config
data:
  config: |
    address-pools:
    - name: default      # 默认命名空间上
      protocol: layer2
      addresses:
      - 192.168.0.150-192.169.0.240  #自己的局域网地址池区间

EOF   #输入EOF，输入文件结束

ingress

kubectl apply -f - << EOF
