Docker 部署 ghost + nginx + mysql

部署前先分层：

用户–>nginx–>ghost（app）–>mysql

创建 3 个容器

层级目录

ghost

Deckerfile

FROM ghost
COPY ./config.production.json /var/lib/ghost/content/config.production.json
EXPOSE 2368
#CMD ["npm","start","--production"]

config.production.json

nginx

Dockerfile

FROM nginx
COPY nginx.conf /etc/nginx/nginx.conf
EXPOSE 80

nginx.conf

worker_processes 4;
events {worker_connections 1024;}
http {
    server {
        listen 80;
        location / {
            proxy_pass http://ghost-app:2368;
        }
    }
}

data

用于存放数据库

docker-compose.yml

version: '2'
networks:
  ghost:
services:
  ghost-app:
    build: ghost
    networks:
      - ghost
    depends_on:
      - db
    ports:
      - "2368:2368"
  nginx:
    build: nginx
    networks: 
      - ghost
    depends_on:
      - ghost-app
    ports:
      - "80:80"
  db:
    image: "mysql:5.7.15"
    networks:
      - ghost
    environment:
      MYSQL_ROOT_PASSWORD: mysqlroot
      MYSQL_USER: ghost
      MYSQL_PASSWORD: ghost
    volumes:
      - $PWD/data:/var/lib/mysql
    ports:
      - "3306:3306"

创建好文件后，直接在当前目录下构建应用并运行

docker-compose up
