How to install PHP composer inside a docker container
PhpLaravelDockerComposer PhpDocker ComposePhp Problem Overview
I try to work out a way to create a dev environment using docker and laravel.
I have the following 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.
I tried:
RUN curl -sS https://getcomposer.org/installer | php -- \
--install-dir=/usr/bin --filename=composer
But when I call
docker-compose up
docker-compose exec app composer dump-autoload
It throws the following error:
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.
Thanks for your support. Also: this is the gitub repository if you need to see the docker-compose.yml file or anything else.
Php Solutions
Solution 1 - Php
In Dockerfile :
COPY --from=composer:latest /usr/bin/composer /usr/local/bin/composer
Solution 2 - Php
I can install composer adding this line on my test dockerfile:
# Install Composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
Here is the 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
# Install Composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
It works for me, to test if the composer are installed i access to my container bash and execute:
composer --version
Composer version 1.6.5 2018-05-04 11:44:59
Solution 3 - Php
This is how i do it with Laravel 8.4 in 2021 to deploy it to CloudRun in Google Cloud:
Dockerfile
#Get Composer
FROM composer:2.0 as vendor
WORKDIR /app
COPY database/ database/
COPY composer.json composer.json
COPY composer.lock composer.lock
RUN composer install \
--no-interaction \
--no-plugins \
--no-scripts \
--no-dev \
--prefer-dist
COPY . .
RUN composer dump-autoload
// some more custom steps like
FROM node:14.9 as frontend
...
FROM php:7.4-fpm
...
// Copy Composer dependencies
# Copy Composer dependencies
COPY --from=vendor app/vendor/ ./vendor/
COPY . .
// Some more custom steps
...
End of my Dockerfile to launch app with cleared optimized cache
# Run Laravel commands
RUN php artisan optimize:clear
CMD php artisan serve --host=0.0.0.0 --port=8080
EXPOSE 8080
Solution 4 - Php
Create an executable of your composer file using
RUN curl -sS https://getcomposer.org/installer | php -- \
--install-dir=/usr/bin --filename=composer && chmod +x /usr/bin/composer
Solution 5 - Php
We have basicly the same command running with the difference,
--install-dir=/usr/local/bin
Alternatively, you should add the composer bin files path to the $PATH variable.
export PATH=$PATH":/usr/bin"
Solution 6 - Php
I'd just like to suggest another way.
Dockerfile:
RUN php -r "readfile('http://getcomposer.org/installer');" | php -- --install-dir=/usr/bin/ --filename=composer
Solution 7 - Php
FROM php:7.3-fpm-alpine
RUN docker-php-ext-install pdo pdo_mysql
RUN docker-php-ext-install mysqli && docker-php-ext-enable mysqli
RUN php -r "readfile('http://getcomposer.org/installer');" | php -- --install-dir=/usr/bin/ --filename=composer
RUN apk update
RUN apk upgrade
RUN apk add bash
RUN alias composer='php /usr/bin/composer'
Solution 8 - Php
use composer in dockerfile using curl
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
Dockerfile
FROM 8.1.4-fpm
RUN apt-get update && apt-get install -y \
git \
curl \
zip \
unzip
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
WORKDIR /var/www
