在我的Kubuntu 18.04中，我尝试为我的Laravel应用程序运行Docker
$ docker --version
Docker version 17.12.1-ce, build 7390fc6
我有3个文件：
.env：
# PATHS
DB_PATH_HOST=./databases
APP_PATH_HOST=./votes
APP_PTH_CONTAINER=/var/www/html/
docker-compose.yml：
version: '3'
services:
web:
build: ./web/Dockerfile.yml
environment:
- APACHE_RUN_USER=www-data
volumes:
- ${DB_PATH_HOST}:${APP_PTH_CONTAINER}
ports:
- 8080:80
working_dir: ${APP_PTH_CONTAINER}
db:
image: mysql
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
MYSQL_ROOT_PASSWORD: 1
volumes:
- ${DB_PATH_HOST}:/var/lib/mysql
adminer:
image: adminer
restart: always
ports:
- 8080:8080
composer:
image: composer:1.6
volumes:
- ${DB_PATH_HOST}:${APP_PTH_CONTAINER}
working_dir: ${APP_PTH_CONTAINER}
command: composer install
/web/Dockerfile.yml：
FROM php:7.2-apache
RUN docker-php-ext-install \
pdo_mysql \
&& a2enmod \
rewrite
当我尝试使用docker-compose up --build时，我得到以下信息：
serge@serge:/mnt/_work_sdb8/wwwroot/lar/DockerApps/votes_docker$ docker-compose up --build

我知道*.py是python语言文件，但是我不使用python语言或不使用python语言，而是使用PHP。
为什么是错误以及如何解决？

apache命令之前停止mysql和docker-compose吗？已修改＃3：
经过一些搜索，我在配置文件中添加了mysql版本并添加了命令选项：
image: mysql:5.7.23
command: --default-authentication-plugin=mysql_native_password --disable-partition-engine-check
并且以上错误已修复。 所以：
1。。在root下的其他控制台中，我运行命令（但仍不确定是否需要它？）
sudo service apache2 stop
sudo service mysql stop
2。。在非root控制台下，我使用key在后台运行：
docker-compose up -d

我的输出没有错误，但我希望像在web/Dockerfile.yml中一样，在项目中有供应商目录：
FROM php:7.2-apache
RUN docker-php-ext-install \
pdo_mysql \
&& a2enmod \
rewrite
但是我看不到这个目录... 安装是否成功？
我不确定下一步要去哪里？

如何解决？
谢谢！
答案 0 :(得分：2)
根据docker-compose文档，如果其中包含build，可以将Dockerfile指定为包含构建上下文路径的字符串。
您使用的Dockerfile.yml文件不是默认文件（Dockerfile），因此在这种情况下，还应指定context和dockerfile：
web:
build:
context: ./web
dockerfile: Dockerfile.yml
最后的docker-compose.yaml是：
version: '3'
services:
web:
build:
context: ./web
dockerfile: Dockerfile.yml
environment:
- APACHE_RUN_USER=www-data
volumes:
- ${DB_PATH_HOST}:${APP_PTH_CONTAINER}
ports:
- 8080:80
working_dir: ${APP_PTH_CONTAINER}
db:
image: mysql
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
MYSQL_ROOT_PASSWORD: 1
volumes:
- ${DB_PATH_HOST}:/var/lib/mysql
adminer:
image: adminer
restart: always
ports:
- 8080:8080
composer:
image: composer:1.6
volumes:
- ${DB_PATH_HOST}:${APP_PTH_CONTAINER}
working_dir: ${APP_PTH_CONTAINER}
command: composer install
添加到MODIFIED部分：
web和adminer都配置为在主机系统的端口8080上分配。这就是为什么您在这里有冲突。要解决上述问题，您需要将adminer绑定到另一个端口8081。
最后的docker-compose.yaml是：
version: '3'
services:
web:
build:
context: ./web
dockerfile: Dockerfile.yml
environment:
- APACHE_RUN_USER=www-data
volumes:
- ${DB_PATH_HOST}:${APP_PTH_CONTAINER}
ports:
- 8080:80
working_dir: ${APP_PTH_CONTAINER}
db:
image: mysql
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
MYSQL_ROOT_PASSWORD: 1
volumes:
- ${DB_PATH_HOST}:/var/lib/mysql
adminer:
image: adminer
restart: always
ports:
- 8081:8080
composer:
image: composer:1.6
volumes:
- ${DB_PATH_HOST}:${APP_PTH_CONTAINER}
working_dir: ${APP_PTH_CONTAINER}
command: composer install
添加到MODIFIED3部分：
我看到您的composer码头工人集装箱出现以下错误：
composer_1 | Composer could not find a composer.json file in /var/www/html
composer_1 | To initialize a project, please create a composer.json file as described in the https://getcomposer.org/ "Getting Started" section
是因为您不小心在${DB_PATH_HOST}配置中放置了${APP_PATH_HOST}而不是composer吗？
composer:
image: composer:1.6
volumes:
- ${DB_PATH_HOST}:${APP_PTH_CONTAINER}
working_dir: ${APP_PTH_CONTAINER}
command: composer install
