我是 Docker 的新手，面临着数天的问题，我不知道该如何管理。这是情况；
我在运行这样的服务（例如apache2和mysql和...）的vps服务器中有一个sudoer用户，并且还提供了一些我不希望通过升级或更改php版本或将Web服务器从apache更改为服务来伤害他们的应用程序nginx。
我想在docker中提供laravel应用程序，并在位于docker-compose.prod.yml的项目根文件夹中构建了此/home/myUser/www/laravelProject文件（包含laravel应用程序）：
version : '3'
networks:
laravel:
volumes :
dbdata:
driver: local
services:
nginx:
image : nginx:stable-alpine
container_name: nginx
ports :
- "8080:80"
volumes :
- ./:/var/www/html ## i think it would make sens if i do like ./:/home/myuser/www/laravelProject ???!!!
- ./nginx/default.prod.conf:/etc/nginx/conf.d/default.conf
depends_on :
- php
- mysql
- redis
- artisan
networks :
- laravel
mysql :
image : mysql:5.7.29
container_name: mysql
restart : unless-stopped
tty : true
ports :
- "4406:3306"
environment :
MYSQL_DATABASE : ${DB_DATABASE}
MYSQL_USER : ${DB_USERNAME}
MYSQL_PASSWORD : ${DB_PASSWORD}
MYSQL_ROOT_PASSWORD: ${DB_PASSWORD}
SERVICE_TAGS : dev
SERVICE_NAME : mysql
volumes :
- dbdata:/var/lib/mysql
- ./mysql/my.cnf:/etc/mysql/my.cnf
networks :
- laravel
php :
build :
context : .
dockerfile: php.prod.dockerFile
container_name: php
volumes :
- ./:/var/www/html
ports :
- "9000:9000"
networks :
- laravel
artisan :
build :
context : .
dockerfile: php.dockerfile
container_name: artisan
volumes :
- ./:/var/www/html
depends_on :
- mysql
working_dir : /var/www/html
entrypoint : ['php', '/var/www/html/artisan']
networks :
- laravel
redis :
container_name: redis
image : redis
ports :
- "6379:6379"
volumes :
- ./:/data
entrypoint : redis-server --appendonly yes
restart : always
networks :
- laravel
对不起，我想我错过了Tab和空格。但是，这是我的php.prod.dockerfile
FROM php:7.4-fpm-alpine
WORKDIR /home/www/html // again it's not supposed to be /home/myUser/www/project ???!!!
RUN docker-php-ext-install pdo pdo_mysql
RUN chown -R www-data:www-data /var/www // i don't really have any sense why i'm doing this !!
我使用命令成功构建了容器（在我的项目根目录中）：
docker-compose -f docker-compose.prod.yml up -d --build
，默认.prod.nginx文件是：
server {
listen 80;
index index.php index.html;
server_name api.myUser.com www.api.myUser.com;
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
root /var/www/html/public;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass php:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
}
不幸的是，当我尝试到达端点api.myUser.com:8080时
This site can’t be reached
http://api.myUser.com:8080/ is unreachable.
ERR_ADDRESS_UNREACHABLE
我想念什么？ （对不起，我的英语）
编辑：这是docker-compose up --build
