更新Istio-IngressGateway TLS证书 [英] Updating Istio-IngressGateway TLS Cert

问题描述

我有一个场景，我需要每24小时更新一次Ingress网关tls cert (/etc/istio/ingressgateway-certs/tls.crt)和密钥.我能够使用C#Kubernetes客户端获取原始字节并创建机密，但但是除非Ingress Gateway重新启动，否则它不会获取更新的证书.是否可以通过代码来实现重新启动入口网关部署?

I have a scenario where I need to update the Ingress gateway tls cert (/etc/istio/ingressgateway-certs/tls.crt) and key every 24 hours. I am able to fetch the raw bytes and create the secret using C# Kubernetes client, but unless the Ingress Gateway restarts, it does not pick up the updated certs. Is there a way to do that through code without restarting the ingress-gateway deployment?

任何其他建议也将受到高度赞赏.

Any other suggestions is also highly appreciated.

推荐答案

您正在通过文件引用来安装证书/密钥. Istio现在支持SDS，因此您可以通过credentialName 挂载证书.此模式将检测到新证书，而无需重新启动.来自文档:

You are mounting your cert/key by file reference. Istio supports SDS now, so you can mount the cert by credentialName . This mode will detect a new cert without restarting. From docs:

 apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: mygateway
spec:
  selector:
    istio: ingressgateway # use istio default ingress gateway
  servers:
  - port:
      number: 443
      name: https
      protocol: HTTPS
    tls:
      mode: SIMPLE
      credentialName: httpbin-credential # must be the same as secret
    hosts:
    - httpbin.example.com

顺便说一句:文档指出...

Btw: docs state that...

秘密名称不应以istio 或prometheus开头，并且秘密不应包含令牌字段.

The secret name should not begin with istio or prometheus, and the secret should not contain a token field.
