k8s中使用cert-manager生成自签名证书
一、安装 cert-manager
注意查看cert-manager和K8S支持的对应版本
我的 k8sv1.28.2，cert-manager v1.12.11
下载 cert-manager.yaml 文件，执行
kubectl apply -f cert-manager.yaml
二、生成自签名证书
- cert-selfsigned.yaml
apiVersion: cert-manager.io/v1
kind: Issuer
metadata:name: selfsignednamespace: module
spec:selfSigned: {}
---
apiVersion: cert-manager.io/v1
kind: Certificate
metadata:name: selfsigned-certnamespace: module
spec:duration: 72hrenewBefore: 10hdnsNames:- zyx.module.cnsecretName: zyx-module-cn-cert-tlsissuerRef:name: selfsigned
- 执行命令
kubectl apply -f cert-selfsigned.yaml
- 查看证书
kubectl describe certificate selfsigned-cert -n module
