如何在 php 容器中從 dockerfile 運行 composer install

Question

美好的一天，我在 Dockerfile 中設置了 php 容器

我正在嘗試使用此命令運行 composer install

WORKDIR '/app'
RUN curl -sS https://getcomposer.org/installer | \
            php -- --install-dir=/usr/bin/ --filename=composer
        CMD bash -c "composer install && php artisan serve --host 0.0.0.0 --port 80"
    EXPOSE 80
    EXPOSE 22
    CMD ["php-fpm"]

但是我沒有收到錯誤消息，並且由於 composer install 沒有工作而無法運行應用程序。只有 laravel 的白屏，這意味着沒有安裝 composer。

如果我在 docker compose up 之后運行

docker run -it --rm -v $(pwd):/app composer/composer install

我收到一個錯誤 Composer 在 /app 中找不到 composer.json 文件要初始化一個項目，請按照https://getcomposer.org/ “入門”部分中的描述創建一個 composer.json 文件

如果我嘗試復制項目目錄，我會收到一個錯誤

COPY /var/www/docker/project /app

錯誤：服務 'php' 無法構建：復制失敗：stat /var/lib/docker/tmp/docker-builder091462376/var/www/docker/project：沒有這樣的文件或目錄雖然我在 docker 中的 php 容器中有卷-compose.yml

volumes:
            - ${APP_PATH_HOST}:${APP_PATH_CONTAINER}
            - /app/vendor/

這是我的 docker-compose.yml

version: '2'
services:
    nginx:
     image: nginx:latest
     container_name: "${PROJECT_NAME}_nginx"
     environment:

        - "443:443"
     volumes:

        - ${APP_PATH_HOST}:${APP_PATH_CONTAINER}

    php:
        build: ./images/php
        links:
            - mariadb
        #command: bash -c 'cd /app composer install'    
        volumes:
            - ${APP_PATH_HOST}:${APP_PATH_CONTAINER}
            - /app/vendor/

    mariadb:
     image: wodby/mariadb:$MARIADB_TAG
     container_name: "${PROJECT_NAME}_mariadb"
     stop_grace_period: 30s
     environment:
      MYSQL_ROOT_PASSWORD: $DB_ROOT_PASSWORD
      MYSQL_DATABASE: $DB_NAME
      MYSQL_USER: $DB_USER
      MYSQL_PASSWORD: $DB_PASSWORD

    pma:
     image: phpmyadmin/phpmyadmin
     container_name: "${PROJECT_NAME}_pma"
     ports:
        - "9000:80"
     environment:
       PMA_HOST: $DB_HOST
       PMA_USER: $DB_USER
       PMA_PASSWORD: $DB_PASSWORD

      - 'traefik.backend=pma'
      - 'traefik.port=80'
      - 'traefik.frontend.rule=Host:pma.${PROJECT_BASE_URL}'

看來您正在混合使用 PHP-FPM 和獨立的 PHP 服務器。 而是將artisan serve轉移到 CMD。 另外，你只能有一個CMD ，它是容器啟動時需要執行的命令。 為了在構建容器時執行其他命令，需要使用RUN命令。 所以你的 Dockerfile 可以是這樣的：

WORKDIR '/app'
RUN curl -sS https://getcomposer.org/installer | \
            php -- --install-dir=/usr/bin/ --filename=composer

RUN "composer install"
EXPOSE 80
EXPOSE 22
CMD "php artisan serve --host 0.0.0.0 --port 80"
