news 来源：原创 2025/4/29 8:47:28

场景：单个pod，部署在主节点，基础版没有插件，进阶版多了一个插件

基础版本：

封装版本：

新增方式：在原有的镜像上将插件拷贝进来，封装多了一个插件文件到/opt/rabbitmq/plugins

封装版本的镜像是需要制作的，制作流程如下：

mkdir test && cd test

ls

tar-1.34.tar.gz   rabbitmq_delayed_message_exchange.tar

vim Dockerfile


#-----第一阶段，为了制作tar包，第二阶段应用到rabbitmq里，第三阶段时rabbitmq插件加载
#FROM swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/selectdb/alpine:latest AS builder
# 修改软件源为国内镜像
#RUN sed -i 's|https://dl-cdn.alpinelinux.org/alpine/|http://mirrors.tuna.tsinghua.edu.cn/alpine/|g' /etc/apk/repositories
# 安装完整的编译工具链和依赖库
#RUN apk update && apk add --no-cache \
#    build-base \
#    gcc \
#    make \
#    autoconf \
#    automake \
#    bison \
#    gettext \
#    libtool \
#    elfutils-dev \
#    ncurses-dev \
#    readline-dev \
#    zlib-dev \
#    musl-dev
# 复制 tar-1.34.tar.gz
#COPY tar-1.34.tar.gz /tar-1.34.tar.gz
# 解压、编译并安装 tar
#RUN tar -zxf /tar-1.34.tar.gz && \
#    cd /tar-1.34 && \
#    FORCE_UNSAFE_CONFIGURE=1 ./configure --prefix=/usr/local && \
#    make && \
#    make install && \
#    rm -rf /tar-1.34 /tar-1.34.tar.gz
# 第二阶段：使用 RabbitMQ 镜像
#FROM swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/rabbitmq:3-management
# 从第一阶段复制编译好的 tar
#COPY --from=builder /usr/local /usr/local##docker build -t rabbitmq-tar:1.1 .
##ls
##tar-1.34.tar.gz Dockerfile#----
#添加插件并且运行容器自动启动
#FROM rabbitmq-tar:1.1
# # 将本地插件包复制到容器内的 /opt/rabbitmq/plugins 目录
#COPY rabbitmq_delayed_message_exchange-3.13.0.ez /opt/rabbitmq/plugins
#启动时加载插件
#RUN rabbitmq-plugins enable --offline rabbitmq_delayed_message_exchange
#
#

#制作镜像
##docker build -t rabbitmq_delayed_message_exchange:1.4 .
##ls
##rabbitmq_delayed_message_exchange.ez Dockerfile

#然后再yaml文件里引用最新镜像即可

#测试是否自动加载插件成功
kubectl exec -it rabbitmq-0 -n middle-ware -- rabbitmq-plugins list |grep rabbitmq_delayed_message_exchange

-----

部署在新环境：pv和pvc大小，账密更改，端口更改，pv目录授权，登录31672/admin/admin123默认的，建议更改

登录curl测试：
http://10.10.10.150:31672/#/
admin/admin123

镜像基于swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/rabbitmq:3-management封装了一层，添加了tar包，还有rabbitmq_delayed_message_exchange.ez插件包，并且每次运行容器会自动启动插件


rabbitmq_delayed_message_exchange.tar是镜像包
使用的话docker load -i rrabbitmq_delayed_message_exchange.tar导入这个tar包
