How to install PHP composer inside a docker container
提问by Andre
I try to work out a way to create a dev environment using docker and laravel.
我尝试找到一种使用 docker 和 laravel 创建开发环境的方法。
I have the following dockerfile:
我有以下 dockerfile：
FROM php:7.1.3-fpm
RUN apt-get update && apt-get install -y libmcrypt-dev \
mysql-client libmagickwand-dev --no-install-recommends \
&& pecl install imagick \
&& docker-php-ext-enable imagick \
&& docker-php-ext-install mcrypt pdo_mysql
&& chmod -R o+rw laravel-master/bootstrap laravel-master/storage
Laravel requires composer to call composer dump-autoload when working with database migration. Therefore, I need composer inside the docker container.
Laravel 需要 Composer 在处理数据库迁移时调用 composer dump-autoload。因此，我需要在 docker 容器中使用 Composer。
I tried:
我试过：
RUN curl -sS https://getcomposer.org/installer | php -- \
--install-dir=/usr/bin --filename=composer
But when I call
但是当我打电话
docker-compose up
docker-compose exec app composer dump-autoload
It throws the following error:
它引发以下错误：
rpc error: code = 13 desc = invalid header field value "oci runtime error: exec failed: container_linux.go:247: starting container process caused \"exec: \\"composer\\": executable file not found in $PATH\"\n"
I would be more than happy for advice how I can add composer to the PATH within my dockerfile or what else I can do to surpass this error.
我很乐意为我提供建议，如何将 Composer 添加到我的 dockerfile 中的 PATH 或者我可以做些什么来克服这个错误。
Thanks for your support. Also: thisis the gitub repository if you need to see the docker-compose.yml file or anything else.
谢谢您的支持。另外：如果您需要查看 docker-compose.yml 文件或其他任何内容，这是 gitub 存储库。

We have basicly the same command running with the difference,
我们有基本相同的命令，但不同的是，
--install-dir=/usr/local/bin
Alternatively, you should add the composer bin files path to the $PATH variable.
或者，您应该将 Composer bin 文件路径添加到 $PATH 变量。
export PATH=$PATH":/usr/bin"
