本文档介绍了如何在Docker环境下基于rabbitmq:3.9.20-management镜像构建新的定制镜像，以包含rabbitmq_delayed_message_exchange延迟队列插件。通过编写Dockerfile，将插件文件复制到镜像中并在启动时启用插件，确保在多主机和多容器环境中无需手动安装。最后验证了插件已成功启用。

以官方的 rabbitmq:3.9.20-management 为例，默认开启的插件有4个，如下所示

2022-07-09 21:31:55.624125+08:00 [info] <0.814.0> started TCP listener on [::]:5672
 completed with 4 plugins.
2022-07-09 21:31:55.933210+08:00 [info] <0.669.0> Server startup complete; 4 plugins started.
2022-07-09 21:31:55.933210+08:00 [info] <0.669.0>  * rabbitmq_prometheus
2022-07-09 21:31:55.933210+08:00 [info] <0.669.0>  * rabbitmq_management
2022-07-09 21:31:55.933210+08:00 [info] <0.669.0>  * rabbitmq_web_dispatch
2022-07-09 21:31:55.933210+08:00 [info] <0.669.0>  * rabbitmq_management_agent

从上面的日志可以看出，默认开启的4个 rabbitmq_prometheus rabbitmq_management rabbitmq_web_dispatch rabbitmq_management_agent。

进入今天的正题，开启延迟队列 rabbitmq_delayed_message_exchange 。

方式一

容器启动后，执行exec -it，然后手工安装。好像这个也行，但是没有达到我的要求。我的要求比较高。试想一下，如果使用docker swarm（会有多主机，多个运行容器的问题，也就是说，以后会有多少个容器是未知的，所以也就不可能docker exec -it 进行安装了）。所以此方案不考滤。

方式二

那就从映像上入手呗。基于官网的说明，那就自己构造镜像（是在官网的基出上哦，不是从零开始）。docker rabbit上有这么一句

FROM rabbitmq:3.8-management
RUN rabbitmq-plugins enable --offline rabbitmq_mqtt rabbitmq_federation_management rabbitmq_stomp

好的，那就试试它吧。

整理一下过程

1、下载延迟队列插件所需的文件，并且放在和Dockerfile文件同一目录下

2、编写Dockerfile脚本

FROM rabbitmq:3.9.20-management
COPY rabbitmq_delayed_message_exchange-3.9.0.ez /plugins
RUN rabbitmq-plugins enable --offline rabbitmq_delayed_message_exchange

3、构建Image

[root@centos7-01 rabbitmq]# docker build -t my-rabbitmq:3.9.20-management .

4、测试一下生成的Image

[root@centos7-01 rabbitmq]# docker run --name  my-rab-test  my-rabbitmq:3.9.20-management

......  省略了一些
