docker rabbitmq 安装 延迟队列 rabbitmq_delayed_message_exchange 插件

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
2022-07-09 14:08:27.502513+00:00 [info] <0.228.0> Feature flags: list of feature flags found:

2022-07-09 14:08:27.551793+00:00 [info] <0.228.0> Feature flags:   [ ] user_limits

......  省略了一些


2022-07-09 14:08:49.027571+00:00 [info] <0.840.0> started TCP listener on [::]:5672
 completed with 5 plugins.

2022-07-09 14:08:49.540134+00:00 [info] <0.685.0>  * rabbitmq_management_agent

可以看到，官方的是4个插件，现在变成了5个了，并且看到了  rabbitmq_delayed_message_exchange

5、提交Image到私服

6、后面使用的话，由   rabbitmq:3.9.20-management 改为  my-rabbitmq:3.9.20-management 即可。
