使用docker build kit构建树莓派上可用的Docker镜像

curl -fsSL https://get.docker.com -o get-docker.shsudo sh get-docker.shsudo usermod -aG ${user_name}

# 在树莓派系统中执行如下命令git clone https://github.com/sameersbn/docker-bind.gitcd docker-bind# 修改Dockerfile内容，注意！！此项设置与docker-bind有关，与build-kit的使用无关，仅做演示用echo 'FROM ubuntu:focal-20200423 AS add-apt-repositoriesCOPY jcameron-key.asc jcameron-key.ascRUN apt-get update / && DEBIAN_FRONTEND=noninteractive apt-get install -y gnupg / && apt-get install -y curl / && apt-key adv --fetch-keys https://www.webmin.com/jcameron-key.asc / && echo "deb http://download.webmin.com/download/repository sarge contrib" >> /etc/apt/sources.listFROM ubuntu:focal-20200423LABEL maintainer="sameer@damagehead.com"ENV BIND_USER=bind /  BIND_VERSION=9.16.1 /  WEBMIN_VERSION=1.970 /  DATA_DIR=/dataRUN apt-get update / && apt-get install -y curlCOPY --from=add-apt-repositories /etc/apt/trusted.gpg /etc/apt/trusted.gpgCOPY --from=add-apt-repositories /etc/apt/sources.list /etc/apt/sources.listRUN rm -rf /etc/apt/apt.conf.d/docker-gzip-indexes / && apt-get update / && DEBIAN_FRONTEND=noninteractive apt-get install -y /   bind9=1:${BIND_VERSION}* bind9-host=1:${BIND_VERSION}* dnsutils /   webmin=${WEBMIN_VERSION}* / && rm -rf /var/lib/apt/lists/*COPY entrypoint.sh /sbin/entrypoint.shRUN chmod 755 /sbin/entrypoint.shEXPOSE 53/udp 53/tcp 10000/tcpENTRYPOINT ["/sbin/entrypoint.sh"]CMD ["/usr/sbin/named"]' > Dockerfile# 登录到自己的docker仓库# 自己使用的是阿里云的镜像仓库，也可以使用dockerhub官方仓库docker login --username=${user_name} registry.cn-hangzhou.aliyuncs.comdocker buildx build --platform linux/aarch64 -t registry.cn-hangzhou.aliyuncs.com/docker-image-lee/bind:aarch64 --no-cache --push .# 如果是在Mac或Windows上执行构建的话，需要首先执行下述命令docker buildx create --use
