Dockerfile构建rabbitmq镜像，并部署到K8S集群暴露端口出来。

一、构建rabbitmq2.8.7版本镜像

背景描述：
rabbitmq 版本：RabbitMQ 2.8.7
erlang版本：otp_src_R16B03
并已事先下载好文件到本地
dockerfile文件如下：

FROM centos:centos7.4.1708
MAINTAINER xiaojun "490089459@qq.com"

RUN yum install -y gcc glibc-devel gcc-c++kernel-develm4 make ncurses-devel openssl-devel xmlto perl wget xz lsof && rpm --rebuilddb
RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo "Asia/Shanghai" > /etc/timezone

ADD otp_src_R16B03 /usr/local/src/otp_src_R16B03
WORKDIR /usr/local/src/otp_src_R16B03

RUN ./configure --prefix=/usr/local/erlang && make && make install

ENV ERL_HOME /usr/local/erlang
ENV PATH $PATH:$ERL_HOME/bin

ADD rabbitmq_server-2.8.7 /usr/local/rabbitmq
WORKDIR /usr/local/rabbitmq

ENV RABBITMQ_HOME /usr/local/rabbitmq
ENV PATH $PATH:$RABBITMQ_HOME/sbin

EXPOSE 5672
EXPOSE 55672

ENTRYPOINT rabbitmq-plugins enable rabbitmq_management && rabbitmq-server

CMD ["rabbitmq-server"]

构建镜像：

docker build -t rabbitmq .

将镜像提交到harbor！
二、K8S部署rabbitmq 单节点
背景描述：
K8S 使用三台服务器组建的新集群
后端存储使用cephfs
