Solution 1

You can build your own image and use it in your Docker compose file.

FROM php:7.2-alpine3.8
RUN apk update
RUN apk add bash
RUN apk add curl
# INSTALL COMPOSER
RUN curl -s https://getcomposer.org/installer | php
RUN alias composer='php composer.phar'
# INSTALL NGINX
RUN apk add nginx

I used the PHP alpine image as my base image because it's lightweight, so you might have to install other dependencies yourself. In your docker-compose file

web:
  build: path/to/your/Dockerfile/directory
  image: your-image-tag
  ports:
    - "8080:80"
  volumes:
    - ./www:/var/www
    - ./nginx.conf:/etc/nginx/sites-enabled/default

Solution 2

You could do something like this:

FROM php:8.0.2-apache
RUN apt-get update && apt-get upgrade -y
RUN apt-get install -y mariadb-client libxml2-dev
RUN apt-get autoremove -y && apt-get autoclean
RUN docker-php-ext-install mysqli pdo pdo_mysql xml
COPY --from=composer /usr/bin/composer /usr/bin/composer

the argument COPY --from= should solve your problem.

Solution 3

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'

I am new at docker and docker-compose and I am developing a Laravel-project on docker and docker-compose with Laradock as following a tutorial(not sure whether It is a correct way or not to refer this situation though).

I want to install the composer in this environment to be able to use the composer command.

As a matter of fact, I wanted to do seeding to put data into DB that I made by php artisan make:migrate but this error appeared.
```
include(/var/www/laravel_practice/vendor/composer/../../database/seeds/AdminsTableSeeder.php): failed to open stream: No such file or directory
```
So I googled this script to find a solution that will solve the error then I found it. It says, "Do composer dump-autoload and try seeding again", so I followed it then this error appeared.
```
bash: composer: command not found
```
Because I have not installed composer into docker-container. My docker's condition is like this now. ・workspace
・mysql
・apache
・php-fpm
Since I have not installed the composer, I have to install it into docker-container to solve the problem, BUT I have no idea how to install it into docker-container.

So could anyone tell me how to install composer into docker-container? Thank you.

here is the laradock/mysql/Dockerfile and laravelProject/docker-compose.yml.
```
ARG MYSQL_VERSION=5.7
FROM mysql:${MYSQL_VERSION}

RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone && chown -R mysql:root /var/lib/mysql/
COPY my.cnf /etc/mysql/conf.d/my.cnf
CMD ["mysqld"]
EXPOSE 3306
```
```

  @prithajnath Thank you for your advice. I modified it and how is it now?

  Much better. Do you happen to have the relevant Dockerfile that you used to create your image/container?

  what is your base image- can you share your Dockerfile?

Thank you so much!!!! I have a question. You said like, "write these code in docker-compose file". Does it mean "docker-compose.yml"?

@pop Yep. I meant the docker-compse.yml file
