如果在kubernetes中使用rabbitmq运算符部署了rabbitmq，如何启用rabbitmq插件“ rabbitmq_delayed_message_exchange”

问题描述

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

我尝试将 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

然后我运行了kubectl apply -f definition.yaml

但是我的 pod日志显示了以下内容：

...
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.
...

日志中没有没有任何引用。插件。

我走进了Rabbitmq吊舱并跑了： rabbitmq插件列表

我也发现了这一点

How to install rabbitmq plugin on kubernetes?

但是没有参考到 rabbitmq运算符，并且在 2018年6月中被询问。同样，在rabbitmq运算符配置中，也没有使用生命周期挂钩来挂载ez文件的任何参考。

我想到的

1个想法是创建自己的 rabbitmq图像，并引用 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，但是我找不到任何在Rabbitmq运算符中使用volumeMounts的引用。 / p>

是否有首选方式或任何其他方式启用它？

解决方法

此插件可以通过使用已安装插件的自定义Docker Rabbitmq映像来启用：

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：为了获得不变的结果或万一您不能依赖外部更改，请将插件下载到您的计算机上并使用COPY而不是RUN curl ...确保具有Rabbitmq_delayed_message_exchange您计算机中的.ez文件。

• 将图像推送到容器注册表。

然后将 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。
