K8S 部署 ingress-nginx (三) 启用 https

部署 https 证书

cd ~/ingress

# 生成私钥 tls.key, 密钥位数是 2048
openssl genrsa -out tls.key 2048

# 使用 tls.key 生成自签证书
openssl req -new -x509 -key tls.key -out tls.crt -subj /C=CN/ST=GuangDong/L=Guangzhou/O=DevOps/CN=tomcat.klvchen.com

kubectl create secret tls tomcat-ingress-secret --cert=tls.crt --key=tls.key
kubectl get secret
kubectl describe secret tomcat-ingress-secret

vi ingress-tomcat-tls.yaml
