ssl - 如果定义了 k8s API tls 密码，则 k8s 上的 Rabbitmq 对等发现失败

Question

我使用 helm chart 在 k8s 上部署 2 个 RabbitMQ pod。图表可以很好地部署和集群。然后为 k8s API 添加一个 tls 定义:

--tls-cipher-suites=TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256

然后RabbitMQ peer discovery插件集群失败。

[root@control-01]$ # kubectl get pod -o wide
oe-crmq-0                                   0/1       CrashLoopBackOff   7          33m       192.168.1.186   worker-01
oe-crmq-1                                   0/1       CrashLoopBackOff   7          32m       192.168.1.105   worker-02

所以我尝试在 advanced.config 中为 RabbitMQ 添加密码:

bash-4.2$ cat advanced.config
%% List allowed ciphers
[
    {ssl, [{versions, ['tlsv1.2']},
           {ssl_optons, [{ciphers, [
                            {ecdhe_rsa,aes_128_gcm,null,sha256}
                            ]}, {fail_if_no_peer_cert,false}]}]}
].

虽然这个配置并没有带来太大的改进。连接到 kubernetes.default.svc.cluster.local 时仍然超时。

将 erlang 升级到最新版本后，问题解决了。
