例如我在我的主机文件中添加website.dev
和我的实际nginxconfiguration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"; } } }
我用这个命令启动我的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.bizzw.com:5000/infra-nginx:dev
哪里
$(ifconfig | grep inet | grep -v inet6 | grep -v 127.0.0.1 | awk '{print $2}') is getting my local ip, not working all the time.
问题是如果我想在没有互联网的情况下工作，我不能。 而当我的IP变化，我不得不重新启动与新的IP容器。
我试着用这个configuration来代替
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"; } } }
并运行
docker run --name infra-nginx --network host -d docker-registry.bizzw.com:5000/infra-nginx:dev
在这种情况下，当我运行时：
curl http://website.dev/
我有
curl: (7) Failed to connect to website.dev port 80: Connection refused

所以当你使用--net host运行它时，它实际上仍然不在mac网络上。 这就是为什么它不工作。
从文档
Mac有一个不断变化的IP地址（或者如果你没有网络访问权限的话）。 从17.06开始，我们的建议是连接到特殊的仅限于Mac的DNS名称docker.for.mac.localhost，该名称将解析为主机使用的内部IP地址。
所以你需要改变你的配置
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://docker.for.mac.localhost:3000; proxy_set_header X-Base-Path "/"; proxy_set_header Website-Name "test"; } } }
你应该如下运行容器
docker run --name infra-nginx -p 80:80 -d docker-registry.bizzw.com:5000/infra-nginx:dev
你让它太复杂了。 只需从您的应用程序容器中将8080这样的端口移出。
在nginx中使用：
listen 80; server_name _; location / { proxy_pass http://127.0.0.2:8080; }
好吧，我认为我所做的解决方案非常简单。
首先我在本地机器上的端口3000上运行nodejs中的应用程序，所以如果我在浏览器中访问localhost：3000，则可以看到该应用程序正在运行。
然后我在我的机器的一个文件夹~/projects/docker/default.conf创建一个名为default.conf的文件， 你可以在任何你想要的地方创建这个文件 。 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; }
}
看看这个行proxy_pass http://localhost:3000; 我重定向到我的本地机器上运行的应用程序。
然后我用下面的命令运行一个nginx container ：
sudo docker run -d -p 80:80 --name="nginx" --net="host" -v ~/projects/docker/default.conf:/etc/nginx/conf.d/default.conf:ro nginx
-p 80:80是将该端口绑定到nginx container
--net="host"是告诉容器，它将使用的网络是一样的主机，这意味着我的机器相同，与此我可以转发到localhost:3000容器内。
-v ~/projects/docker/default.conf:/etc/nginx/conf.d/default.conf:ro是告诉nginx它的配置文件是我在本地机器上的文件。
它的意思是这样的：你会在~/projects/docker/default.conf /etc/nginx/conf.d/default.conf ~/projects/docker/default.conf位置找到这个/etc/nginx/conf.d/default.conf文件
就这样。
如果我去我的浏览器，只输入localhost （没有端口） ，它将通过nginx container ，将被重定向到我的本地计算机上运行localhost:3000的应用程序
让我知道这是否有助于你
