Node.js Nginx docker作为本地节点代理

目前，我正在使用docker中的nginx代理我的节点应用程序

例如，我在主机文件中添加

website.dev

我实际的nginx配置是

worker_processes 4;
pid /run/nginx.pid;

events {}

http {

    server {
      listen 80;
      server_name website.dev;
      location / {
          proxy_pass    http://localnode:3000;
          proxy_set_header X-Base-Path "/";
          proxy_set_header Website-Name "test";
      }
    }
}

我用这个命令启动docker容器

docker run --name infra-nginx --add-host localnode:$(ifconfig | grep inet | grep -v inet6 | grep -v 127.0.0.1 | awk '{print $2}') -p 80:80 -d docker-registry.host.com:5000/infra-nginx:dev

在哪里

问题是如果我想在没有互联网的情况下工作，我就不能。 当我的ip改变时，我必须用新的ip重新启动容器

我试过使用这个配置

worker_processes 4;
pid /run/nginx.pid;

events {}

http {

    server {
      listen 80;
      server_name localhost;
      location / {
          return 200 'gangnam style!';
      }
    }

    server {
      listen 80;
      server_name website.dev;
      location / {
          proxy_pass    http://localhost:3000;
          proxy_set_header X-Base-Path "/";
          proxy_set_header Website-Name "test";
      }
    }
}

跑步

docker run --name infra-nginx --network host -d docker-registry.host.com:5000/infra-nginx:dev

在这种情况下，当我跑步时：

curl http://website.dev/

我有

curl: (7) Failed to connect to website.dev port 80: Connection refused

docker ps

你把事情弄得太复杂了。只需从应用程序容器中公开一个类似8080的端口

在nginx中使用：

listen 80;
server_name _;

location / {
   proxy_pass http://127.0.0.2:8080;
}

---

所以，当您使用

--nethost

运行它时，它实际上仍然不在mac网络上。这就是它不起作用的原因

从

Mac有一个不断变化的IP地址（如果您没有网络访问权限，则没有）。从17.06开始，我们建议连接到专用的Mac专用DNS名称docker.for.Mac.localhost，该名称将解析为主机使用的内部IP地址

因此，您需要将配置更改为

worker_processes 4;
pid /run/nginx.pid;

events {}

http {

    server {
      listen 80;
      server_name localhost;
      location / {
          return 200 'gangnam style!';
      }
    }

    server {
      listen 80;
      server_name website.dev;
      location / {
          proxy_pass    http://docker.for.mac.localhost:3000;
          proxy_set_header X-Base-Path "/";
          proxy_set_header Website-Name "test";
      }
    }
}

您应该按如下方式运行容器

docker run --name infra-nginx -p 80:80 -d docker-registry.host.com:5000/infra-nginx:dev

好的，我认为我的解决方案很简单

首先，我在本地机器的端口3000上运行nodejs中的一个应用程序，因此如果我在浏览器中转到localhost:3000，我可以看到该应用程序正在运行

然后，我在我的机器

~/projects/docker/default.conf

的文件夹中创建一个名为

default.conf

的文件，您可以在任何地方创建该文件。并将此代码粘贴到文件中：

server {
listen 80;

server_name myapp.com;

location / {
    proxy_pass http://localhost:3000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
}

}

看这行

proxy\u passhttp://localhost:3000;我正在重定向到在本地计算机上运行的应用程序

然后使用以下命令运行
nginx容器
：

sudo docker run -d -p 80:80 --name="nginx" --net="host" -v ~/projects/docker/default.conf:/etc/nginx/conf.d/default.conf:ro  nginx

-p80:80
将该端口绑定到
nginx容器

--net=“host”
是告诉容器它将使用的网络与主机相同，这意味着与我的机器相同，这样我就可以从容器内部转发到
localhost:3000

-v~/projects/docker/default.conf:/etc/nginx/conf.d/default.conf:ro
是告诉
nginx
它的配置文件将是我在本地机器中拥有的文件

它的意思是：您将在这个
~/projects/docker/default.conf
位置找到这个
/etc/nginx/conf.d/default.conf
文件

就这些

如果我进入浏览器并键入
localhost
（不带端口），它将通过
nginx容器
，并将重定向到本地计算机中运行在
localhost:3000
中的应用程序

让我知道这是否有助于您使用
curl进行错误连接http://website.dev/
，我将
docker ps
的postAdd输出更新为您的问题更新，容器正在运行，没有使用
网络主机的端口
进入容器并运行
netstat-plant
并添加输出。另外，节点应用程序没有运行到容器中，我无法轻松从容器访问我的ip
server {
listen 80;

server_name myapp.com;

location / {
    proxy_pass http://localhost:3000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
}

sudo docker run -d -p 80:80 --name="nginx" --net="host" -v ~/projects/docker/default.conf:/etc/nginx/conf.d/default.conf:ro  nginx
