Nginx docker作為本地的nodejs代理
[英]Nginx docker as nodejs proxy in local
問題描述
目前我在docker中使用nginx代理我的節點應用程序
例如，我在我的主機文件中添加了website.dev
而我的實際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";
}
}
}
我用這個命令啟動我的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.host.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.
問題是，如果我想在沒有互聯網的情況下工作，我不能。 當我的ip更改時，我必須使用新的ip重新啟動容器。
我嘗試使用此配置
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
在這種情況下，當我運行時：
curl http://website.dev/
我有
curl: (7) Failed to connect to website.dev port 80: Connection refused

3 個解決方案
解決方案1
2 已采納 2017-10-03 09:31:39
因此，當您使用--net host運行它時，它實際上仍然不在mac網絡上。 這就是為什么它不起作用。
從文檔中
Mac具有更改的IP地址（如果您沒有網絡訪問權限，則為無）。 從17.06開始，我們建議連接到特殊的Mac-DNS DNS名稱docker.for.mac.localhost，它將解析為主機使用的內部IP地址。
所以你需要將配置更改為
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";
}
}
}
你應該運行如下容器
docker run --name infra-nginx -p 80:80 -d docker-registry.host.com:5000/infra-nginx:dev
解決方案2

你做得太復雜了。 只需從您的應用容器中顯示8080這樣的端口即可。
在nginx中使用：
listen 80;
server_name _;
location / {
proxy_pass http://127.0.0.2:8080;
}
解決方案3
1 2017-10-04 02:23:18
好吧我認為我做的解決方案很簡單。
首先，我在本地機器上的端口3000上運行了nodejs中的應用程序，所以如果我在瀏覽器中轉到localhost：3000，我可以看到該應用正在運行。
然后我在我的機器~/projects/docker/default.conf的文件夾中創建一個名為default.conf的文件， 您可以在任何地方創建該文件 。 並將此代碼粘貼到文件中：
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;
}
}
查看proxy_pass http://localhost:3000; 我正在重定向到我在本地計算機上運行的應用程序。
然后我用以下命令運行一個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是將該端口綁定到nginx container
--net="host"是告訴容器它將使用的網絡與主機相同，它意味着與我的機器相同，我可以從容器內轉發到localhost:3000 。
-v ~/projects/docker/default.conf:/etc/nginx/conf.d/default.conf:ro告訴nginx它的配置文件將是我本地機器上的文件。
它意味着：你會在這個~/projects/docker/default.conf /etc/nginx/conf.d/default.conf ~/projects/docker/default.conf位置找到這個/etc/nginx/conf.d/default.conf文件
就這樣。
如果我進入我的瀏覽器並輸入localhost （沒有端口） ，它將通過nginx container ，並將被重定向到我本地計算機中localhost:3000中運行的應用程序
如果這有助於您，請告訴我
