docker-compose - Composer在/ var / www / html中找不到composer.json文件

Question

Trying to make docker container for my project and after using docker-compose up --build command I get this error: Composer could not find a composer.json file in /var/www/html.

My Dockerfile:

FROM php:7.2-apache

    RUN docker-php-ext-install \
        pdo_mysql \
        && a2enmod \
        rewrite

.env file

#PATHS

DB_PATH_HOST=./databases

APP_PATH_HOST=./wedding-planner

APP_PATH_CONTAINER=/var/www/html

part of docker-compose.yml

    version: '3'

    services:

        web:
            build: ./web
            environment:
                - APACHE_RUN_USER=www-data
[...]
        composer:
            image: composer:1.6
            volumes:
                - ${APP_PATH_HOST}:${APP_PATH_CONTAINER}
            working_dir: ${APP_PATH_CONTAINER}
            command: composer install

Where should I put composer.json to make it work?

Answer 1

I don't think your docker-compose.yml file is replacing the variables properly.

You can try something like this to export the variables for replacement:

set -a
. .env
set +a
docker-compose up -d --build
