用docker-compose搭建ghost 的学习笔记及其遇到的问题

学习笔记

安装docker-compose

//下载并安装docker-compose
curl -L https://github.com/docker/compose/releases/download/1.9.0/docker-compose-$(uname -s)-$(uname -m) > /usr/local/bin/docker-compose
ll /usr/local/bin/docker-compose
//赋予权限
chmod a+x /usr/local/bin/docker-compose

docker-compose --version

ghost文件结构及配置

• docker/ghost/docker-compose.yum

  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"

• docker/ghost/ghost/Dockerfile

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

注意：最新的ghost 需要禁掉 CMD ["npm", "start", "--production"]

• docker/ghost/ghost/config.js

  var path = require('path'),
  config;

  config = {
  production:{
  url: 'http://mytestblog.com',
  mail: {},
  database: {
  client: 'mysql',
  connection: {
  host: 'db',
  user: 'ghost',
  password: 'ghost',
  database: 'ghost',
  prot: '3306',
  charset: 'utf8'
  },
  debug: false
  },
  paths: {
  contenPath: path.join(process.env.GHOST_CONTENT,'/')
  },
  server: {
  host: '0.0.0.0',
  port: '2368'
  }
  }
  };

  module.exports = config;

• docker/ghost/nginx/Dockerfile

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

• docker/ghost/nginx/nginx.conf

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

• docker/ghost/data
  此为空文件夹

遇到的问题

docker-compose ps 状态码错误
Exit 254
docker-compose logs ghost-app

ghost-app_1 | npm ERR! code ENOENT
ghost-app_1 | npm ERR! syscall open
ghost-app_1 | npm ERR! path /var/lib/ghost/package.json
ghost-app_1 | npm ERR! errno -2
ghost-app_1 | npm ERR! enoent ENOENT: no such file or directory, open '/var/lib/ghost/package.json'

如下图所示

解决办法

docker/ghost/ghost/Dockerfile 下

CMD ["npm", "start", "--production"] 删除

停止docker-compose 服务

docker-compose stop

删除原有的容器

docker-compose rm

重新构建

docker-compose build

重新启动服务即可

docker-compose up -d

查看相关容器

docker-compose ps
