Question

我正在学习docker，并试图为Symfony项目设置环境。在我将迁移和夹具创建命令添加到entrypoint.sh之前，它工作良好。现在，运行entrypoint.sh中的所有命令后，php容器将以代码0退出。有人可以帮我吗？

这是我的设置：

docker-compose.yaml

version: "3.7"

services:
    nginx:
        image: nginx:alpine
        ports:
            - ${NGINX_HOST_PORT}:80
        volumes:
            - ./public:/var/www/symfony/public
            - ./docker/nginx/default.conf:/etc/nginx/conf.d/default.conf
        depends_on:
            - php

    php:
        build:
            context: .
            dockerfile: docker/php/Dockerfile
        volumes:
            - symfony:/var/www/symfony:delegated
        depends_on:
            - mysql
            - redis
            - composer
        environment:
            REDIS_HOST: redis
            REDIS_PORT: 6379

    redis:
        image: redis:alpine

    composer:
        image: composer:latest
        command: install
        volumes:
            - symfony:/app

    mysql:
        image: mysql:latest
        command: --default-authentication-plugin=mysql_native_password
        ports:
            - ${MYSQL_HOST_PORT}:3306
        environment:
            MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}
            MYSQL_DATABASE: ${MYSQL_DATABASE}

volumes:
    symfony:
    #        driver: local
    #        driver_opts:
    #            type: none
    #            o: bind
    #            device: ${PWD}:${PWD}
        driver: local
        driver_opts:
            type: nfs
            o: addr=host.docker.internal,rw,nolock,hard,nointr,nfsvers=3
            device: ${PWD}:${PWD}

用于php容器的Dockerfile：

FROM php:7.3-fpm-alpine

ENV APP_DEPENDENCIES \
    curl \
    vim \
    git

ENV PHP_EXTENSIONS \
    pdo_mysql

ENV PECL_EXTENSIONS \
    xdebug \
    redis

RUN apk add --no-cache ${APP_DEPENDENCIES} ${PHPIZE_DEPS} && \
    docker-php-ext-install ${PHP_EXTENSIONS} && \
    pecl install ${PECL_EXTENSIONS} && \
    docker-php-ext-enable ${PECL_EXTENSIONS}

COPY ./ /var/www/symfony
COPY docker/entrypoint.sh /usr/local/bin/entrypoint.sh

CMD ["/usr/local/bin/entrypoint.sh"]

entrypoint.sh：

#!/bin/sh

APP_PATH="/var/www/symfony"

echo "applying db migrations"
${APP_PATH}/bin/console doctrine:migrations:migrate first
${APP_PATH}/bin/console doctrine:migrations:migrate
${APP_PATH}/bin/console doctrine:fixtures:load

第一件事，容器将在执行入口点脚本时死亡，因为没有任何使容器在入口点运行的过程。应该始终有一个进程能够保持运行，以使容器不会死亡。

第二件事，您没有在入口点中启动php-fpm，因此您的容器将不会在容器中启动PHP。

更新您的入口点。

#!/bin/sh
APP_PATH="/var/www/symfony"
echo "all params $@"
echo "applying db migrations"
${APP_PATH}/bin/console doctrine:migrations:migrate first
${APP_PATH}/bin/console doctrine:migrations:migrate
${APP_PATH}/bin/console doctrine:fixtures:load
echo "starting php-fpm"
exec $@

更新Dockerfile中的CMD

CMD ["/usr/local/bin/entrypoint.sh","php-fpm","-F"]

运行Symfony控制台命令后，Docker php-fpm容器以代码0退出
