阿里云ESC

创建实例

填入密码即可

云上的防火墙相关设置就是安全组

vpc 专有网络 划分私有ip 子网

vpc 隔离环境域 不同的vpc下 即使相同的子网也不互通

使用交换机继续划分子网

停止 释放 不收钱

k8s

服务器 4核8G*1 + 8核16G *2

git 创建凭证

pipeline 发邮箱 (p124)

k8s 想要发邮件 admin 账号 登录 平台管理 平台设置 通知管理 邮件

admin 工作负载 jenkinsfile 编辑配置文件 配置邮箱

两个地址都需要配置

pipeline 推送镜像

创建凭证

容器镜像服务 个人即可 创建仓库和命名空间 从一个仓库的基本信息中找到仓库地址
例如registry.cn-hangzhou.aliyuncs.com
找到命名空间 例如 jhj

deploy 部署

创建kubeconfig

拉取镜像 由于我们使用阿里云的 所以需要使用阿里云

同时在项目的配置中心 密钥处配置
密钥类型

k8s kubekey 部署

删除之前部署的kk

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

下载配置文件

export KKZONE=cn 
curl -sfL https://get-kk.kubesphere.io | VERSION=v2.2.2 sh -

生成配置文件

./kk create config --name kk-k8s

使用内部负载均衡部署

apiVersion: kubekey.kubesphere.io/v1alpha2
kind: Cluster
metadata:name: kk-k8s
spec:hosts:- {name: node1, address: 172.16.0.2, internalAddress: 172.16.0.2, user: ubuntu, password: "Qcloud@123"}- {name: node2, address: 172.16.0.3, internalAddress: 172.16.0.3, user: ubuntu, password: "Qcloud@123"}roleGroups:etcd:- node1control-plane: - node1worker:- node1- node2controlPlaneEndpoint:## Internal loadbalancer for apiservers internalLoadbalancer: haproxydomain: lb.kubesphere.localaddress: ""port: 6443kubernetes:version: v1.23.8clusterName: cluster.localautoRenewCerts: truecontainerManager: dockeretcd:type: kubekeynetwork:plugin: calicokubePodsCIDR: 10.233.64.0/18kubeServiceCIDR: 10.233.0.0/18## multus support. https://github.com/k8snetworkplumbingwg/multus-cnimultusCNI:enabled: falseregistry:privateRegistry: ""namespaceOverride: ""registryMirrors: []insecureRegistries: []addons: []

部署

./kk create cluster -f kk-k8s.yaml --with-kubeshpere v3.2.0

如果想同时部署kubeshpere 加上 --with-kubeshpere v3.2.0 即可

查看集群状态

kubectl get node -o wide

kubeshpere 默认密码为admin

kubekey官网详细的参考

https://github.com/kubesphere/kubekey/blob/master/docs/config-example.md

kubesphere 其实就是ks-installer

https://github.com/kubesphere/ks-installer/blob/master/deploy/cluster-configuration.yaml

如果想开启其他配置可以去查看api 开启配置

https://github.com/kubesphere/kubekey/tree/master/cmd/kk/apis/kubekey/v1alpha2

kk 增加节点

修改config.yaml

执行

./kk add nodes -f config.yaml

kk删除节点

执行

./kk delete node node3 -f config.yaml

集群证书管理

查看到期时间

./kk certs check-expiration -f config.yaml

更新集群证书

默认在 /etc/kubernetes/pki

执行命令更新证书

./kk certs renew -f config.yaml

1.2 2.0 插件自动安装 自动更新

应用商店

在安装后 开启一些组件 crud 中 配置项改为true
