Chrome 不能打开 kubernetes Dashboard 解决方法
步骤：
mkdir key && cd key
#生成证书
openssl genrsa -out dashboard.key 2048
openssl req -new -out dashboard.csr -key dashboard.key -subj '/CN=kubernetes-dashboard-certs'
openssl x509 -req -in dashboard.csr -signkey dashboard.key -out dashboard.crt
#删除原有的证书secret
kubectl delete secret kubernetes-dashboard-certs -n kube-system
#创建新的证书secret
kubectl create secret generic kubernetes-dashboard-certs --from-file=dashboard.key --from-file=dashboard.crt -n kube-system
#查看dashboard pod，v2.0是 -n kubernetes-dashboard
kubectl get pod -n kube-system
#重启dashboard pod，v2.0是 -n kubernetes-dashboard
kubectl delete pod <pod name> -n kube-system在部署 Dashboard 时手动创建证书
- 修改配置文件
vi dashboard.yaml
---
#因为自动生成的证书很多浏览器无法使用，所以我们自己创建，注释掉kubernetes-dashboard-certs对象声明
#apiVersion: v1
#kind: Secret
#metadata:
# labels:
# k8s-app: kubernetes-dashboard
# name: kubernetes-dashboard-certs
# namespace: kubernetes-dashboard
#type: Opaque
---- 创建证书
mkdir dashboard-certs
cd dashboard-certs/
#创建命名空间
kubectl create namespace kubernetes-dashboard
# 创建key文件
openssl genrsa -out dashboard.key 2048
#证书请求，CN=可修改为实际IP或者域名
openssl req -days 36000 -new -out dashboard.csr -key dashboard.key -subj '/CN=kubernetes-dashboard-certs'
#自签证书
openssl x509 -req -in dashboard.csr -signkey dashboard.key -out dashboard.crt
#创建kubernetes-dashboard-certs对象
kubectl create secret generic kubernetes-dashboard-certs --from-file=dashboard.key --from-file=dashboard.crt -n kubernetes-dashboard备注：dashboard v2.0 namespace 是 kubernetes-dashboard
