使用docker compose一次性部署所有容器

我们通过docker部署了nginx，mongo，parse-server和parse-dashboard，但如果每次都需要这么一个个的部署，略微有点麻烦，这时候，我们的docker compose上场了。

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration.

至于如何编写docker compose的yaml文件，具体的请参考官方文档 docker compose docs

这边给出最终我们一次性配置的yaml文件内容

nginx的配置文件的修正

通过Https访问Parse Server和Parse Dashboard文章中，在配置反向代理时，我们使用的是parse-server和parse-dashboard容器的内部IP地址，这就有不确定性，每次容器重启IP都有可能变化，因此需要实时的去修改nginx的配置文件并重启。
使用docker compose，则可以避免这个问题，此时，我们可以使用服务名直接进行访问。

server {
    listen       80;
    server_name  localhost; # 换成自己的host
    
    # http请求重定向到https上
    rewrite  ^(.*)$  https://${server_name}$1  permanent;
