docker - 如果使用 kubernetes 中的 rabbitmq 操作符部署 rabbitmq，如何启用 rabbitmq 插件“rabbitmq_delayed_message_exchange”

Question

我在kubernetes中使用rabbitmq 运算符部署了一个rabbitmq实例。我正在尝试启用rabbitmq 插件： rabbitmq_delayed_message_exchange。

我尝试将我的RabbitmqCluster定义为：

apiVersion: rabbitmq.com/v1beta1
kind: RabbitmqCluster
metadata:
  name: definition
spec:
  replicas: 1
  rabbitmq:
    additionalPlugins:
      - rabbitmq_management
      - rabbitmq_delayed_message_exchange
  service:
    type: LoadBalancer

然后我跑了kubectl apply -f definition.yaml

但我的pod 日志显示了这一点：

...
2020-10-05T15:42:15.081783023Z 2020-10-05 15:42:15.081 [info] <0.535.0> Server startup complete; 6 plugins started.

2020-10-05T15:42:15.081951576Z  completed with 6 plugins.
...

日志中没有对此插件的任何引用。

我进入我的 rabbitmq pod 并运行：rabbitmq-plugins list

所以这意味着插件没有集成。

我还发现了这个：

如何在 kubernetes 上安装 rabbitmq 插件？

但是没有提到rabbitmq操作符，它是在2018年6月被问到的。同样在 rabbitmq 操作员配置中，没有任何关于使用生命周期挂钩挂载 ez 文件的参考。

我想到的1 个想法是创建我自己的rabbitmq 图像，引用rabbitmq 官方图像并添加插件。

FROM rabbitmq:3.8.8-management

RUN apt-get update

RUN apt-get install -y curl

RUN curl -L https://github.com/rabbitmq/rabbitmq-delayed-message-exchange/releases/download/v3.8.0/rabbitmq_delayed_message_exchange-3.8.0.ez > $RABBITMQ_HOME/plugins/rabbitmq_delayed_message_exchange-3.8.0.ez

RUN chown rabbitmq:rabbitmq $RABBITMQ_HOME/plugins/rabbitmq_delayed_message_exchange-3.8.0.ez

RUN rabbitmq-plugins enable --offline rabbitmq_delayed_message_exchange

RUN rabbitmq-plugins enable --offline rabbitmq_consistent_hash_exchange

第二个想法是通过使用文件定义配置映射并使用 volumeMounts 将文件挂载到 pod 文件目录中，但我找不到任何将 volumeMounts 与 rabbitmq 运算符一起使用的参考。

是否有首选方式或任何其他方式来启用它？

可以使用安装了插件的自定义 Docker Rabbitmq 映像启用此插件：

FROM rabbitmq:3.8.8-management

RUN apt-get update

RUN apt-get install -y curl

RUN curl -L https://github.com/rabbitmq/rabbitmq-delayed-message-exchange/releases/download/v3.8.0/rabbitmq_delayed_message_exchange-3.8.0.ez > $RABBITMQ_HOME/plugins/rabbitmq_delayed_message_exchange-3.8.0.ez

RUN chown rabbitmq:rabbitmq $RABBITMQ_HOME/plugins/rabbitmq_delayed_message_exchange-3.8.0.ez

RUN rabbitmq-plugins enable --offline rabbitmq_delayed_message_exchange

RUN rabbitmq-plugins enable --offline rabbitmq_consistent_hash_exchange

注意：对于不可变的结果或如果您不能依赖外部更改，请将插件下载到您的机器并使用 COPY 而不是使用 RUN curl...确保您的机器中有 rabbitmq_delayed_message_exchange .ez 文件。

• 将您的图像推送到容器注册表。

然后将您的RabbitmqCluster定义为：

apiVersion: rabbitmq.com/v1beta1
kind: RabbitmqCluster
metadata:
  name: definition
spec:
  image: <container-registry>/<username>/rabbitmq-delayed-message-exchange:3.8.8-management
  replicas: 1
  rabbitmq:
    additionalPlugins:
      - rabbitmq_management
      - rabbitmq_delayed_message_exchange
  service:
    type: LoadBalancer

注意：将图像更改为您推送的图像。
