[英]docker nginx load balancing not working with Azure
Ok been trying this setup for a full day now. 好的,现在已经尝试了一整天了。 I cannot get Nginx to connect the domain name that
azure
gave me to my node
docker
containers. 我无法让Nginx将
azure
给我的域名连接到我的node
docker
容器。
I'm using Azure
to create a VM
. 我正在使用
Azure
创建VM
。 The DNS name
is scout-1j013s34.cloudapp.net
The virtual IP address
is 191.237.66.86
DNS name
是scout-1j013s34.cloudapp.net
virtual IP address
是191.237.66.86
I can ssh
into the VM
with ssh monty@scout-1j013s34.cloudapp.net -p 61777
. 我可以
ssh
到VM
与ssh monty@scout-1j013s34.cloudapp.net -p 61777
。 I'm not sure why I need to specify a port? 我不确定为什么需要指定端口?
The VM
is running Ubuntu 14.04
. VM
正在运行Ubuntu 14.04
。 I installed docker
myself. 我自己安装了
docker
。
I found and followed the following tutorial A sample Docker workflow with Nginx, Node.js and Redis
我找到并遵循了以下教程
A sample Docker workflow with Nginx, Node.js and Redis
I built, and ran the containers as shown below. 我构建并运行了容器,如下所示。
Here is my nginx.conf
file 这是我的
nginx.conf
文件
worker_processes 4;
events { worker_connections 1024; }
http {

least_conn;
server node1:1337 weight=10 max_fails=3 fail_timeout=30s;
server node2:1337 weight=10 max_fails=3 fail_timeout=30s;
server node3:1337 weight=10 max_fails=3 fail_timeout=30s;
}
server {
listen 80;
server_name 191.237.66.86 scout-1j013s34.cloudapp.net www.scout-1j013s34.cloudapp.net;
location / {
proxy_pass http://node-app;
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;
}
}
}
when I enter http://scout-1j013s34.cloudapp.net/
into the browser address bar, it times out. 当我在浏览器地址栏中输入
http://scout-1j013s34.cloudapp.net/
时,它超时了。
Update: I have EXPOSE 1337
in my Dockerfile
to expose the 1337 ports for each node container. 更新:我有
EXPOSE 1337
在我Dockerfile
揭露1337个端口,每个节点的容器。
For each node container I ran docker run -it --name node1 --link mongo:MONGODB -v /home/monty/scout/backend-api/:/scout-sails mlennie/scout-sails bash
changing the name to node2 and node3 for the next 2 then I went into each container and started the sails.js
app with sails lift
. 对于每个节点容器,我都
docker run -it --name node1 --link mongo:MONGODB -v /home/monty/scout/backend-api/:/scout-sails mlennie/scout-sails bash
将名称更改为node2并接下来的2个node3,然后我进入每个容器,并用sails.js
sails lift
启动了sails.js
应用程序。
Then I started the nginx container and linked it to the 3 node containers with the command docker run -d --name nginx -p 80:80 --link node1:node1 --link node2:node2 --link node3:node3 mlennie/nginx
然后我启动了nginx容器,并使用命令
docker run -d --name nginx -p 80:80 --link node1:node1 --link node2:node2 --link node3:node3 mlennie/nginx
将其链接到3个节点容器docker run -d --name nginx -p 80:80 --link node1:node1 --link node2:node2 --link node3:node3 mlennie/nginx
好的,我可以正常工作了,我需要通过Azure管理门户手动添加一个端口为80的终结点。
