本文介绍如何使用tls-gen库生成SSL证书，并在RabbitMQ中配置使用这些证书进行安全通信的过程。通过创建并配置HelmRelease，部署RabbitMQ实例，并在实例中启用TLS，确保消息队列服务的安全性。

生成ssl证书

克隆tls-gen库
$ git clone https://github.com/michaelklishin/tls-gen.git
$ cd tls-gen/basic

生成root ca及相关证书
$ PASSWORD=bunnies make    （设置证书密码，并生成证书）
$ ls -lha ./result         （ca, server, client证书都在里面）

验证证书
$ make verify

默认CN用的是hostname，也可以指定CN
$ CN=secure.mydomain.local PASSWORD=bunnies make

创建rabbitmq flux HelmRelease文件 rabbitmq.yaml:

---
apiVersion: flux.weave.works/v1beta1
kind: HelmRelease
metadata:
  name: rabbitmq
  namespace: default
  annotations:
    flux.weave.works/automated: "true"
spec:
  releaseName: rabbitmq
  chart:
    repository: http://mirror.azure.cn/kubernetes/charts/
    name: rabbitmq
    version: 6.7.4
  values:

      password: admin
      extraPlugins: "rabbitmq_shovel rabbitmq_shovel_management rabbitmq_federation rabbitmq_federation_management"
      extraConfiguration: |-
        ssl_options.versions.1 = tlsv1.2
        ssl_options.versions.2 = tlsv1.1

提交代码到个人的 Flux Repo

手动触发flux同步

$ fluxctl sync --k8s-fwd-ns flux

检查rabbitmq运行状态

$ kubectl get pod rabbitmq-0
NAME         READY   STATUS    RESTARTS   AGE
rabbitmq-0   2/2     Running   2          4h10m

创建测试脚本目录
$ mkdir test_scripts
$ cd test_scripts

拷贝ssl证书
$ mkdir ssl
$ cp ./result/{ca_certificate.pem,client_certificate.pem,client_key.pem} ssl/

创建发送端send.go:

package main

import (
	"crypto/tls"
	"crypto/x509"
	"io/ioutil"
	"log"

	"github.com/streadway/amqp"
)

// 只能在安装 rabbitmq 的服务器上操作
func main() {
