Question

I m trying to Dockerize my laravel app. The app is already built and in git, but I .gitignore my vendor folder. I ve added a Dockerfile, which looks like this:

FROM php:7.1-fpm-alpine

RUN apk update && apk add curl && 
  curl -sS https://getcomposer.org/installer | php 
  && chmod +x composer.phar && mv composer.phar /usr/local/bin/composer

RUN apk --no-cache add --virtual .build-deps $PHPIZE_DEPS 
  && apk --no-cache add --virtual .ext-deps libmcrypt-dev freetype-dev 
  libjpeg-turbo-dev libpng-dev libxml2-dev msmtp bash openssl-dev pkgconfig 
  && docker-php-source extract 
  && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ 
                                   --with-png-dir=/usr/include/ 
                                   --with-jpeg-dir=/usr/include/ 
  && docker-php-ext-install gd mcrypt mysqli pdo pdo_mysql zip opcache 
  && pecl install mongodb redis xdebug 
  && docker-php-ext-enable mongodb 
  && docker-php-ext-enable redis 
  && docker-php-ext-enable xdebug 
  && docker-php-source delete 
  && apk del .build-deps

WORKDIR /var/www/html

COPY composer.json composer.lock ./
RUN composer install --no-scripts --no-autoloader

COPY . .
RUN chmod +x artisan

RUN composer dump-autoload --optimize && composer run-script post-install-cmd

CMD php artisan serve --host 0.0.0.0 --port 5001

When I build, this seems to work great. I see the dependencies getting downloaded, I see the autoload file being generated in the output. However, once the build is complete, the vendor folder is not actually there. I m guessing it was all done in an intermediate container which was then removed? So when I run docker-compose up, I get: Fatal error: require(): Failed opening required /var/www/html/bootstrap/../vendor/autoload.php

这个帖子似乎指向可能的问题，但并没有真正提供解决方案：运行Dockerfile时，Composer安装不安装软件包

Answer 1

This took a lot of digging for someone new to Docker :) Thanks to @iurii-drozdov for pointing me in the right direction with the comment about the docker-compose.yml.

在我的docker-compose.yml文件中，我将主机的工作目录挂载到/var/www/html目录下。这是在构建完成之后进行的。因此，当composer运行install时，它会在构建时正确地安装所有依赖项，然后，在运行docker-compose up时，我挂载主机目录到容器中并覆盖了所有更改。

The solution was to run composer install after mounting the volume. It s straight forward enough to do this by simply exec ing into the container after bringing it up - running composer and any other package managers - then finally running the web server.

然而，我找到了更简洁的解决方案。我将Dockerfile中的最终CMD更改为：

CMD bash -c "composer install && php artisan serve --host 0.0.0.0 --port 5001"

这将运行Composer安装并作为docker-compose up的最后一部分启动Web服务器。

Answer 2

你也可以使用官方的DockerHub Composer镜像。

这是一个多阶段构建的示例，其中使用独立容器先运行Composer。生成的 /app/vendor 将复制到您最终镜像中想要的任何位置。

FROM composer as builder
WORKDIR /app/
COPY composer.* ./
RUN composer install
...
FROM php:7.1-fpm-alpine
...
COPY --from=builder /app/vendor /var/www/vendor

Answer 3

如果您不想在Dockerfile中使用该命令，我们发现最简单的方法是将其添加到我们的docker-compose文件中：

composer_installation:
  container_name: composer_installation
  image: composer
  volumes:
    - ./:/app
  command: composer install --ignore-platform-reqs

更新有点慢，可能是因为正在与PHP容器同步。

Answer 4

根据。

跑步

WORKDIR /your/base/path
COPY --from=composer /usr/bin/composer /usr/bin/composer
RUN composer install

Answer 5

我使用这一指挥,并产生供应商:

docker run --rm -it --volume $(pwd):/app prooph/composer:7.2 install --ignore-platform-reqs

Answer 6

答案见: min 9:30。在码头。警告你,在批量配置中,只须为供应商目录添加一条道路,以避免过度使用:

volumes:
  - /var/www/html/vendor
