【6-3 compose實戰】2022-03-10成功運行說明（1）各個鏡像的內容和配置文件的內容
首先，對前面評論和提問題的小伙伴表示感謝，他們給我了很多提示和信息。
另外，要說明的是，因為大家都是初學者，老師給的例子沒有指定ghost的版本，所以拉取的會是最新版本，所以很有可能我下面的說明隨著ghost新的版本更新也會有一些問題，無法運行。
但是現在測試是沒有問題的，我完全跑起來了，也寫下來給后來的小伙伴們分享。
首先是ghost鏡像的Dockerfile內容：
FROM ghost:3-alpine
COPY ./config.js /var/lib/ghost/content/config.js
EXPOSE 2368
接下來是配置文件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',
??????????? port: '3306',
??????????? charset: 'utf8'
??????? },
??????? debug: false
??? },
??? paths: {
??????? contentPath: path.join(process.env.GHOST_CONTENT, '/')
??? },
??? server: {
??????? host: '0.0.0.0',
??????? port: '2368'
??? }
? }
};
?
module.exports = config;
nginx鏡像文件內容：
FROM nginx
COPY nginx.conf /etc/nginx/nginx.conf
EXPOSE 80
nginx配置文件內容：
worker_processes 4;
events {
??? worker_connections 1024;
}
http {
??? server {
??????? listen 80;
??????? location / {
??????????? proxy_pass http://ghost-app:2368;
??????? }
??? }
}
docker-compose.yml文件的內容：
