[转]K8S 安装 Dashboard

-------------

1、在 master 节点执行

本例 k8s 是 v1.17.2，对应的 dashboard 是 v2.0.0-rc5 这个版本，

具体去这里查看对应的版本 Releases · kubernetes/dashboard · GitHub

wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-rc5/aio/deploy/recommended.yaml

# 创建 pod
kubectl apply -f recommended.yaml
2、查看，成功创建

[root@master1 ~]# kubectl get pods --all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE
default nginx-5578584966-ch9x4 1/1 Running 1 8h
kube-system coredns-9d85f5447-qghnb 1/1 Running 38 6d13h
kube-system coredns-9d85f5447-xqsl2 1/1 Running 37 6d13h
kube-system etcd-master1 1/1 Running 8 6d13h
kube-system kube-apiserver-master1 1/1 Running 9 6d13h
kube-system kube-controller-manager-master1 1/1 Running 8 6d13h
kube-system kube-flannel-ds-amd64-h2f4w 1/1 Running 5 6d10h
kube-system kube-flannel-ds-amd64-z57qk 1/1 Running 1 10h
kube-system kube-proxy-4j8pj 1/1 Running 1 10h
kube-system kube-proxy-xk7gq 1/1 Running 7 6d13h
kube-system kube-scheduler-master1 1/1 Running 9 6d13h
kubernetes-dashboard dashboard-metrics-scraper-7b8b58dc8b-5r22j 1/1 Running 0 15m
kubernetes-dashboard kubernetes-dashboard-866f987876-gv2qw 1/1 Running 0 15m
3、 删除现有的dashboard服务，dashboard 服务的 namespace 是 kubernetes-dashboard，但是该服务的类型是ClusterIP，不便于我们通过浏览器访问，因此需要改成NodePort型的

# 查看 现有的服务
[root@master1 ~]# kubectl get svc --all-namespaces
NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
default kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 6d13h
default nginx NodePort 10.102.220.172 <none> 80:31863/TCP 8h
kube-system kube-dns ClusterIP 10.96.0.10 <none> 53/UDP,53/TCP,9153/TCP 6d13h
kubernetes-dashboard dashboard-metrics-scraper ClusterIP 10.100.246.255 <none> 8000/TCP 61s
kubernetes-dashboard kubernetes-dashboard ClusterIP 10.109.210.35 <none> 443/TCP 61s
# 删除
kubectl delete service kubernetes-dashboard --namespace=kubernetes-dashboard
4、创建配置文件

vim dashboard-svc.yaml

# 内容
kind: Service
apiVersion: v1
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard
namespace: kubernetes-dashboard
spec:
type: NodePort
ports:
- port: 443
targetPort: 8443
selector:
k8s-app: kubernetes-dashboard


# 执行
kubectl apply -f dashboard-svc.yaml
5、再次查看服务，成功

[root@master1 ~]# kubectl get svc --all-namespaces
NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
default kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 6d13h
default nginx NodePort 10.102.220.172 <none> 80:31863/TCP 8h
kube-system kube-dns ClusterIP 10.96.0.10 <none> 53/UDP,53/TCP,9153/TCP 6d13h
kubernetes-dashboard dashboard-metrics-scraper ClusterIP 10.100.246.255 <none> 8000/TCP 4m32s
kubernetes-dashboard kubernetes-dashboard NodePort 10.110.91.255 <none> 443:30432/TCP 10s
7、想要访问dashboard服务，就要有访问权限，创建kubernetes-dashboard管理员角色

vim dashboard-svc-account.yaml

# 结果
apiVersion: v1
kind: ServiceAccount
metadata:
name: dashboard-admin
namespace: kube-system
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
name: dashboard-admin
subjects:
- kind: ServiceAccount
name: dashboard-admin
namespace: kube-system
roleRef:
kind: ClusterRole
name: cluster-admin
apiGroup: rbac.authorization.k8s.io


# 执行
kubectl apply -f dashboard-svc-account.yaml
8、获取 token

[root@master1 ~]# kubectl get secret -n kube-system |grep admin|awk '{print $1}'
dashboard-admin-token-bwgjv


# 复制下面的 token,后面登陆的时候要用到
[root@master1 ~]# kubectl describe secret dashboard-admin-token-bwgjv -n kube-system|grep '^token'|awk '{print $2}'
eyJhbGciOiJSUzI1NiIsImtpZCI6IkJOVUhyRElPQzJzU2t6VDNVdWpTdzhNZmZPZjV0U2s1UXBFTzctNE9uOFEifQ.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.kEK3XvUXJGzQlBI4LIOp-puYzBBhhXSkD20vFp9ET-rGErxmMHjUuCqWxg0iawbuOndMARrpeGJKNTlD2vL81bXMaPpKb4Y2qoB6bH5ETQPUU0HPpWYmfoHl4krEXy7S95h0mWehiHLcFkrUhyKGa39cEBq0B0HRo49tjM5QzkE6PNJ5nmEYHIJMb4U62E8wKeqY9vt60AlRa_Re7IDAO9qfb5_dGEmUaIdr3tu22sa3POBsm2bhr-R3aC8vQzNuafM35s3ed8KofOTQFk8fXu4p7lquJnji4yfC77yS3yo5Jo3VPyHi3p5np_9AuSNYfI8fo1EpSeMsXOBH45hu2w
10、访问

https://192.168.2.102:30432

把上面的 token 粘贴到令牌
