Docker – 使用Macos buildx制作image同时支持x86和arm

1. 在orbstack设定做更改：settings > docker > 改用containerd

{
  "features" : {
    "containerd-snapshotter" : true
  }
}

2. 可以去到dockerhub 参考原生版本支持的环境，这里的例子是php

https://hub.docker.com/_/php/tags?name=8.0-apache

3. 编写dockerfile

FROM php:8.0-apache

RUN apt-get update && apt-get install -y \
    git \
    zip \
    curl \
    sudo \
    unzip \
    libgd-dev \
    libicu-dev \
    libbz2-dev \
    libpng-dev \
    libjpeg-dev \
    libmcrypt-dev \
    libreadline-dev \
    libfreetype6-dev \
    g++ \
    libssl-dev \
    zlib1g-dev \
    libonig-dev \
    libxml2-dev \
    libicu-dev \
    zip \
    libzip-dev

# Clear cache
RUN apt-get clean && rm -rf /var/lib/apt/lists/*

RUN docker-php-ext-install mysqli pdo pdo_mysql bz2 intl iconv bcmath opcache calendar gd zip mbstring

RUN apt-get update && apt-get install -y \
    libfreetype6-dev \
    libjpeg62-turbo-dev \
    libpng-dev \
    && docker-php-ext-configure gd --with-freetype --with-jpeg \
    &&  docker-php-ext-install -j$(nproc) gd \
    && pecl install -o -f redis \
    &&  rm -rf /tmp/pear \
    &&  docker-php-ext-enable redis

4. 执行buildx命令，我使用的container registry是aws的，以下的命令是build完之后就直接push到registry了

docker buildx build --no-cache \
--platform=linux/386,linux/arm64/v8,linux/arm/v7,linux/arm/v5,linux/amd64 \
-f dockerfile \
-t 233333.dkr.ecr.ap-southeast-1.amazonaws.com/php:8.0-apache-x86-arm \
--push .
