Linux多节点部署KubeSphere

Linux节点部署 kubesphere
2023-06-13 09:17:12 时间

一、准备环境

  • 4c8g （master）
  • 2c4g * 2（worker）
  • centos7.9
  • 内网互通
  • 每个机器有自己域名
  • 防火墙开放 30000~32767 端口

二、使用 KubeKey 创建集群

1、下载 KubeKey

export KKZONE=cn


curl -sfL https://get-kk.kubesphere.io | VERSION=v1.1.1 sh -

chmod +x kk

2、创建集群配置文件

./kk create config --with-kubernetes v1.20.4 --with-kubesphere v3.1.1

3、创建集群

./kk create cluster -f config-sample.yaml

这里需要修改一下 config-sample.yaml

config-sample.yaml 示例文件:

apiVersion: kubekey.kubesphere.io/v1alpha1
kind: Cluster
metadata:
  name: sample
spec:
  hosts:
    - {
        name: k8s-master,

        internalAddress: 10.0.2.15,
        user: root,
        password: 123456,
      }
    - {
        name: k8s-node1,
        address: 10.0.2.7,
        internalAddress: 10.0.2.7,
        user: root,
        password: 123456,
      }
    - {
        name: k8s-node2,
        address: 10.0.2.8,
        internalAddress: 10.0.2.8,
        user: root,
        password: 123456,
      }

      - k8s-master
    worker:
      - k8s-node1
      - k8s-node2

报错：conntrack is required.

# 解决方式
yum install -y conntrack

4、查看进度

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f
