一、部署Dashboard主节点
介绍
1.1、查看集群状态
1.2、下载yaml文件并运行Dashboard
1.3、部署服务
1.4、创建访问账户、获取token令牌
1.5、浏览器访问Dashboard
二、安装kubectl自动补全命令主节点
2.1、安装bash-completion工具
2.2、执行bash_completion
2.3、加载kubecel completion 一、部署Dashboard主节点 前提部署好一个Kubernetes集群可以按照我上一章的文章进行部署
介绍 Kubernetes Dashboard是一个用于可视化管理和监控Kubernetes集群的Web用户界面。它提供了一种图形化的方式来查看和管理集群中的资源、应用程序和服务。使得用户可以更方便地进行操作和监控
1.1、查看集群状态 确保状态为Ready
[rootk8s-master ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
k8s-master Ready master 7m49s v1.18.0
k8s-node01 Ready none 7m20s v1.18.0
k8s-node02 Ready none 7m18s v1.18.0
1.2、下载yaml文件并运行Dashboard
# 下载yaml文件如果下载失败那就多下载几次
[rootk8s-master ~]# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml
# 修改kubernetes-dashboard的Service类型
[rootk8s-master ~]# vim recommended.yaml
apiVersion: v1
kind: Namespace
metadata:name: kubernetes-dashboard
---
apiVersion: v1
kind: ServiceAccount
metadata:labels:k8s-app: kubernetes-dashboardname: kubernetes-dashboardnamespace: kubernetes-dashboard
---
kind: Service
apiVersion: v1
metadata:labels:k8s-app: kubernetes-dashboardname: kubernetes-dashboardnamespace: kubernetes-dashboard
spec:type: NodePort # 增加ports:- port: 443targetPort: 8443nodePort: 30009 # 增加selector:k8s-app: kubernetes-dashboard
## 部分内容省略
1.3、部署服务
[rootk8s-master ~]# kubectl apply -f recommended.yaml
namespace/kubernetes-dashboard created
serviceaccount/kubernetes-dashboard created
service/kubernetes-dashboard created
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-csrf created
secret/kubernetes-dashboard-key-holder created
configmap/kubernetes-dashboard-settings created
role.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrole.rbac.authorization.k8s.io/kubernetes-dashboard created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
service/dashboard-metrics-scraper created
deployment.apps/dashboard-metrics-scraper created
# 查看kubernetes-dashboard命令空间下的资源
[rootk8s-master ~]# kubectl get pod,svc -n kubernetes-dashboard
NAME READY STATUS RESTARTS AGE
pod/dashboard-metrics-scraper-6b4884c9d5-787lm 0/1 ImagePullBackOff 0 41s
pod/kubernetes-dashboard-7b544877d5-6l4tw 0/1 ErrImagePull 0 41s
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/dashboard-metrics-scraper ClusterIP 10.111.21.8 none 8000/TCP 41s
service/kubernetes-dashboard NodePort 10.106.240.109 none 443:30009/TCP 41s
1.4、创建访问账户、获取token令牌 Dashboard支持kuberconfig和Token两种认证方式这里选择Token认证方式登录
# 创建账号dashboard-admin
[rootk8s-master ~]# kubectl create serviceaccount dashboard-admin -n kubernetes-dashboard
serviceaccount/dashboard-admin created
# 账号授权绑定cluster-admin角色
[rootk8s-master ~]# kubectl create clusterrolebinding dashboard-admin --clusterrolecluster-admin --serviceaccountkubernetes-dashboard:dashboard-admin
clusterrolebinding.rbac.authorization.k8s.io/dashboard-admin created
# 获取账号token
[rootk8s-master ~]# kubectl describe secrets -n kubernetes-dashboard $(kubectl -n kubernetes-dashboard get secret| awk /dashboard-admin/ {print $1})
Name: dashboard-admin-token-dtb6c
Namespace: kubernetes-dashboard
Labels: none
Annotations: kubernetes.io/service-account.name: dashboard-adminkubernetes.io/service-account.uid: b5885626-bc73-45ba-a7eb-b327fa576d95
Type: kubernetes.io/service-account-token
Dataca.crt: 1025 bytes
namespace: 20 bytes

1.5、浏览器访问Dashboard 访问地址https://192.168.93.101:30009 如果访问不到那就是镜像没拉取下来可以使用魔法或者私信评论免费提供 出现以下的页面代表成功 二、安装kubectl自动补全命令主节点 安装之后再使用kubectl命令的时候就可以使用tab键自动补全命令了
2.1、安装bash-completion工具 通常安装在所有master节点上
[rootk8s-master ~]# yum -y install bash-completion
2.2、执行bash_completion
[rootk8s-master ~]# source /usr/share/bash-completion/bash_completion
2.3、加载kubecel completion
# 在当前bash环境中临时设置命令补全
[rootk8s-master ~]# source (kubectl completion bash)
# 在当前bash环境中永久设置命令补全
[rootk8s-master ~]# echo source (kubectl completion bash) ~/.bashrc
[rootk8s-master ~]# source ~/.bashrc
