现状

目前市面上和官方均只有rocketmq x86架构下的docker镜像，而随着国产化和信创适配的需求越来越多，显然现有的x86架构下的docker镜像不能满足多样化的需求，因此我们需要根据官方发布的版本制作满足需求的多架构镜像，以在不同cpu架构下部署使用。

 rocketmq官方网站：RocketMQ · 官方网站 | RocketMQ

关于rocketmq的介绍请阅读官方文档，这里就不做过多赘述。

前提条件

1. 构建镜像的机器需要能访问互联网，拥有良好的网络环境

2. 构建之前请搭建好私有仓库，比如harbor、registry这种，以便将多架构镜像推送到镜像仓库中

3. 需要安装docker，版本要求19.03以上，并支持buildx插件

准备工作

 1. 编写Dockerfile文件

# 多阶段构建方式
cat  Dockerfile-centos################################################################################
# Build stage 1 `builder`:
# Download and extract RocketMQ
################################################################################
FROM eclipse-temurin:8-jdk-centos7 AS builderARG versionRUN set -eux \&& yum -y update \&& yum -y install curl gnupg unzip \&& yum clean all -yRUN curl -L https://archive.apache.org/dist/rocketmq/${version}/rocketmq-all-${version}-bin-release.zip -o rocketmq.zip \&& curl -L https://archive.apache.org/dist/rocketmq/${version}/rocketmq-all-${version}-bin-release.zip.asc -o rocketmq.zip.asc \&& curl -L https://www.apache.org/dist/rocketmq/KEYS -o KEYS \&& gpg --import KEYS \&& gpg --batch --verify rocketmq.zip.asc rocketmq.zipRUN unzip rocketmq.zip \&& mkdir -p /tmp/rocketmq-${version} \&& mv rocketmq*/* /tmp/rocketmq-${version}################################################################################
# Build stage 2:
# Make the actual RocketMQ docker image
################################################################################
FROM eclipse-temurin:8-jdk-centos7ARG user=rocketmq

# Dummy overridable parameter parsed by entrypoint
CMD ["dummy"]

2. 编写需要的脚本文件

# 脚本文件docker-entrypoint.sh
cat  docker-entrypoint.sh#!/bin/bash
set -e# Allow user specify custom CMD, maybe run /bin/bash to check the image
if [[ "$1" == "nameserver" || "${NODE_ROLE}" == "nameserver" ]]; thenshiftexec ./mqnamesrv "${@}"
elif [[ "$1" == "broker" || "${NODE_ROLE}" == "broker" ]]; thenshiftexec ./mqbroker "${@}"
elif [[ "$1" == "controller" || "${NODE_ROLE}" == "controller" ]]; thenshiftexec ./mqcontroller "${@}"
else# Run whatever command the user wantsexec "$@"
fi

如何构建

# 如何使用脚本构建呢？1. 创建相关目录，将文件放到对应目录下mkdir  scriptsmv docker-entrypoint.sh scripts/mv runbroker-customize.sh scripts/mv runserver-customize.sh scripts/2. 登陆harbordocker login harbor.codemiracle.com.cn3. 执行构建脚本sh  build-image.sh [rocketmq版本号]eg: sh  build-image.sh 4.5.2
