rancher配置https域名访问图文教程

本文档详细介绍了如何使用openssl生成HTTPS证书,并将其添加到证书列表中。接着,讲解了如何配置负载均衡域名,特别强调了在配置Nginx时选择服务而不是工作负载,并指定端口为80。最后,提到了验证步骤和注意事项,包括私钥去密码、DNS解析、LVS负载分发等。整个请求流程从浏览器输入HTTPS域名,经过DNS解析,到达LVS服务器,再由Nginx-ingress处理请求,直至返回结果。

1.首先参考以下教程生成证书

使用openssl生成https证书https://baijiahao.baidu.com/s?id=1649462735958571118&wfr=spider&for=pc

2.然后将证书添加到证书列表,如下图所示:

3 然后配置负载均衡域名,如下图所示: 

 

4:验证,如下图所示

注意事项:

  • 生成的私钥记得去除密码:

命令如下所示:

openssl rsa -in server.key -out server.key

  • 配置nginx 的 负载均衡域名时,添加规则那里,选择服务,不要选择工作负载,端口填写80即可!
  • 我测试的域名是,通过自己搭建的dns服务解析的,你也可以将域名配置在host文件那里,如果域名请求是通过lvs 负载分发过来的,lvs配置80端口转发请求到真实服务器即可。
  • 此处我前面搭建了lvs+keepalived做前端负载,整个请求链如下

浏览器输入https域名地址进行请求->dns服务解析域名-> 请求来到  lvs服务器->nginx-ingress->nginx 接受请求返回结果。

To configure HTTPS for Rancher, you can follow these steps: 1. **Install Certificates**: You need to install SSL certificates on your Rancher server. This can be done using Let's Encrypt or any other certificate authority. If you're using Let's Encrypt, you can use the `cert-manager` to automatically handle the certificate issuance and renewal process [^3]. 2. **Configure Ingress**: After installing the necessary certificates, you need to configure the ingress controller to use these certificates. This involves setting up an Ingress resource that references the certificate secret created by cert-manager [^5]. 3. **Update Rancher Configuration**: Update the Rancher configuration to use the HTTPS endpoint. This typically involves updating the Rancher deployment to reference the new ingress settings [^1]. 4. **Test Configuration**: Finally, test the configuration to ensure that HTTPS is working correctly. You can do this by accessing the Rancher UI via the HTTPS URL and verifying that there are no certificate warnings [^4]. Here is a sample configuration snippet for configuring an Ingress with TLS support in Kubernetes: ```yaml apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: rancher-ingress namespace: cattle-system annotations: nginx.ingress.kubernetes.io/ssl-passthrough: "true" spec: tls: - hosts: - rancher.example.com secretName: tls-rancher-ingress rules: - host: rancher.example.com http: paths: - path: / pathType: Prefix backend: service: name: rancher port: number: 443 ``` Make sure to replace `rancher.example.com` with your actual domain name and `tls-rancher-ingress` with the name of your TLS secret [^5].
