K8S的dashboard部署与访问

先查看自己k8s版本

kubeadm version

Kubernetes Dashboard 与 Kubernetes 版本的兼容关系需严格对应

下载对应版本的yaml文件，我这里是2.7

curl -O https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml

因为recommended.yaml默认是运行集群内访问，可以改成nodeport

直接在recommended.yaml文件里加上这行即可

查看svc

kubectl get svc -n kubernetes-dashboard

查看pod

kubectl get pod -n kubernetes-dashboard

web访问

Dashboard 需要通过 Token 认证登录，需创建具有管理员权限的 ServiceAccount

cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: ServiceAccount
metadata:name: admin-usernamespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:name: admin-user
roleRef:apiGroup: rbac.authorization.k8s.iokind: ClusterRolename: cluster-admin
subjects:
- kind: ServiceAccountname: admin-usernamespace: kubernetes-dashboard
EOF

获取token

kubectl -n kubernetes-dashboard create token admin-user

把结果粘贴到web的输入栏即可

完成dashboard的部署与访问
