wordpress - 如何使用Nginx前端通过两个Docker容器运行的两个wordpress网站。

Question

我有两个wordpress实例，每个实例作为一个docker容器运行。我想通过单个nginx服务器前端/代理这两个wordpress实例。

以下是我的nginx配置文件。

upstream docker-site1 {
 server site1_site;
}

upstream docker-site2 {
 server site2_site;
}

server {
  listen         80;
  server_name    myserver.domain.com;

  proxy_set_header Host "myserver.domain.com"; # required for Docker client sake
  proxy_set_header X-Real-IP $remote_addr; #pass on real client IP
  client_max_body_size 0; # disable any limits to avoid HTTP 413 for large image uploads
  # required to avoid HTTP 411: see issue #1486 (https://github.com/dotcloud/docker/issues/1486)
  chunked_transfer_encoding on;

  location /site2 {
    auth_basic "Restricted";
    auth_basic_user_file /etc/nginx/pass/.site1_htpasswd;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_pass http://docker-site2/;

  }

  location / {
    auth_basic "Restricted";
    auth_basic_user_file /etc/nginx/pass/.site1_htpasswd;
    proxy_set_header Host $http_host;
    add_header HTTP_HOST $http_host;
    proxy_pass http://docker-site1;
    proxy_http_version 1.1;
  }
}

有一个nginx代理镜像可以自动代理您的容器。您可以找到它here。像这样运行代理:

$ docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro jwilder/nginx-proxy

然后，您必须使用环境变量运行wordpress图片

$docker run -e VIRTUAL_HOST=foo.bar.com ...
$docker run -e VIRTUAL_HOST=bar.foo.com ...

或者，更好的是，在您的Dockerfile中添加ENV指令并公开端口

# My Wordpress 1 Dockerfile
ENV VIRTUAL_HOST=foo.bar.com
EXPOSE 80
