一：安装 docker、docker-compose

系统环境

麒麟 Server V7.0 RedHat 7.6

arm64 CPU

无公网环境

docker 安装

下载 docker 安装包 docker-18.06.3-ce.tgz

（https://download.docker.com/linux/static/stable/aarch64/）

将安装包上传服务器,解压并拷贝可执行文件至/usr/bin/目录

tar -xvf docker-18.06.3-ce.tgz

mv docker-18.06.3-ce docker

cp docker/* /usr/bin/

将 docker 注册为 service 并设置开机自启

vim /etc/systemd/system/docker.service

将以下内容写入文档然后保存

[Unit]

Description=Docker Application Container Engine

Documentation=https://docs.docker.com

After=network-online.target firewalld.service

Wants=network-online.target

[Service]

Type=notify

# the default is not to use systemd for cgroups because the delegate issues

still

# exists and systemd currently does not support the cgroup feature set required

# for containers run by docker

ExecStart=/usr/bin/dockerd

ExecReload=/bin/kill -s HUP $MAINPID

# Having non-zero Limit*s causes performance problems due to accounting overhead

# in the kernel. We recommend using cgroups to do container-local accounting.

LimitNOFILE=infinity

LimitNPROC=infinity

LimitCORE=infinity

# Uncomment TasksMax if your systemd version supports it.

# Only systemd 226 and above support this version.

#TasksMax=infinity

TimeoutStartSec=0

# set delegate yes so that systemd does not reset the cgroups of docker

containers

Delegate=yes

# kill only the docker process, not all processes in the cgroup

KillMode=process

# restart the docker process if it exits prematurely

Restart=on-failure

StartLimitBurst=3

StartLimitInterval=60s

[Install]

WantedBy=multi-user.target

启动 docker

chmod +x /etc/systemd/system/docker.service

systemctl daemon-reload #重载 unit 配置文件

systemctl start docker #启动 Docker

systemctl enable docker.service #设置开机自启

systemctl status docker #查看运行状态

安装 docker-compose[官方无 arm64 安装包，此安装包来自网络]

下载 docker-compose 提取码: gjg9 （https://pan.baidu.com/share/init?

surl=WZqgLne4zeDW5X_jpBFJfQ）

上传至服务器并安装

mv docker-compose-Linux-aarch64 /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose

docker-compose -v # 查看 docker-compose 版本

二：构建 docker 镜像

系统环境

本地系统（X86）

docker 镜像运行环境（arm64）

打包环境构建

docker 版本大于等于 19.03(docker 安装参考官方教程)

启用 buildx

export DOCKER_BUILDKIT=1

export DOCKER_CLI_EXPERIMENTAL=enabled

systemctl restart docker #重启 docker 服务

启用并验证 binfmt_misc

docker run --rm --privileged

docker/binfmt:66f9012c56a8316f9244ffd7622d7c21c1f6f28d

ls -al /proc/sys/fs/binfmt_misc/ #能看到 register、status

docker run --rm --privileged multiarch/qemu-user-static:register --reset

ls -al /proc/sys/fs/binfmt_misc/ #能看到很多 qemu 起头的文件

镜像构建器

docker buildx create --use --name mybuilder # 创建并使用构建器

docker buildx ls # 查看可用的构建器

docker buildx inspect mybuilder --bootstrap # 启动构建器

构建 docker 镜像(以构建 arm64 环境可运行的 alpine Oracle-JDK 镜像为例)

编写 Dockerfile

#FROM multiarch/alpine:aarch64-edge

#FROM arm64v8/alpine:3.8.4

FROM arm64v8/alpine:3.13.3

MAINTAINER "hegd<hegd@summit.com.cn>"

LABEL version="1.0"

LABEL description="arm64 alpine jdk base image"

#设置国内软件仓库镜像

#RUN sed -i 's!http://dl-cdn.alpinelinux.org/!https://mirrors.ustc.edu.cn/!g'

/etc/apk/repositories

#更换 Alpine 源为 mirrors.ustc.edu.cn

#RUN echo http://mirrors.ustc.edu.cn/alpine/v3.13/main > /etc/apk/repositories \

# && echo http://mirrors.ustc.edu.cn/alpine/v3.13/community >>

/etc/apk/repositories

RUN echo "https://mirrors.aliyun.com/alpine/v3.13/main/" > /etc/apk/repositories

RUN echo "https://mirrors.aliyun.com/alpine/v3.13/community/" >>

/etc/apk/repositories

WORKDIR /glibc

COPY ./jdk-base/glibc/ /glibc/
