Kubernetes部署dashboard

Kubernetes集群安装

鲲鹏arm64架构下安装KubeSphere

linux安装部署k8s(kubernetes)和解决遇到的坑

dashboard部署

$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml# 开启本机访问代理　proxy代理只能本机访问
$ kubectl proxykubectl proxy --address='0.0.0.0' --port=8001
kubectl proxy --address='0.0.0.0' --port=30099 --accept-hosts='^*$'

访问
http://192.168.1.53:30099/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login

加了允许外部访问，使用token 登录无反应，跳过登录进入后，有问题，看不了内容

kubectl -n kube-system describe $(kubectl -n kube-system get secret -n kube-system -o name | grep namespace) | grep token　获取token

创建用户

参考:
https://www.cnblogs.com/RainingNight/p/deploying-k8s-dashboard-ui.html

创建服务账号, 首先创建一个叫admin-user的服务账号，并放在kube-system名称空间下
# admin-user.yaml
apiVersion: v1
kind: ServiceAccount
metadata:name: admin-usernamespace: kube-system执行kubectl create命令
kubectl create -f admin-user.yaml绑定角色, 默认情况下，kubeadm创建集群时已经创建了admin角色，我们直接绑定即可
# admin-user-role-binding.yaml
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:name: admin-user
roleRef:apiGroup: rbac.authorization.k8s.iokind: ClusterRolename: cluster-admin
subjects:
- kind: ServiceAccountname: admin-usernamespace: kube-system执行kubectl create命令
kubectl create -f  admin-user-role-binding.yaml获取Token, 现在我们需要找到新创建的用户的Token，以便用来登录dashboard
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')

然后把Token复制到登录界面的Token输入框中，登入后显示如下

查看pod

kubectl get pods --namespace kube-system
get pods -n kube-system | grep -v Running
kubectl get services --namespace kube-system

kubeadm 部署的k8s集群 Dashboard遇到的问题

使得pod不会分配到到master节点上
kubectl delete -f　https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yamlwget https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yamlcat kubernetes-dashboard.yaml

执行命令
kubectl delete -f kubernetes-dashboard.yaml  kubectl create -f kubernetes-dashboard.yaml 

配置　type: NodePort　让外部访问
https://192.168.1.53:30001/#!/namespace?namespace=default

使用token登录
kubectl -n kube-system describe $(kubectl -n kube-system get secret -n kube-system -o name | grep namespace) | grep token
