kubernetes 安装 kubernetes-dashboard 7.x

2024-07-08

helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/

# 我的集群使用默认参数安装 kubernetes-dashboard-kong 出现异常 8444 端口占用
# 使用下面的命令进行安装，在安装时关闭kong.tls功能
helm upgrade --install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard --namespace kube-system --set kong.admin.tls.enabled=false

確認都正常

kubectl get pod -A
kubectl get svc -A

GCP 可以直接指定外部IP

kubectl patch svc kubernetes-dashboard-kong-proxy -n kube-system -p '{"spec": {"type": "LoadBalancer"}}'
kubectl get svc kubernetes-dashboard -n kube-system

一般 kubernetes 可指定 IP

kubectl patch svc kubernetes-dashboard -n kubernetes-dashboard -p '{"spec": {"type": "LoadBalancer", "externalIPs":["192.168.0.144"]}}'
