You need to expose the port of the node.js container to which nginx(angular) container will connect. See the Connect using network port mapping section of docker documentation.

Update : I think, you need to configure the nginx configuration file to the node container. This question has sample nginx file related to your use case (although, not related to containers).

Edit : To map the node app with the nginx, you first need to link the node container with nginx container.

docker run -d -p 80:80 --name "nginx" --link nodejs:nodejs localhost:5000/test/nginx:1

When you link the node container with the nginx container, the node container's address will be saved in the /etc/hosts. So the nginx container can access the node's address from there.

So, in nginx configuration file, the nodejs will be accessible as nodejs' container address:

http {

        upstream node-app {
              server nodejs:8888 weight=10 max_fails=3 fail_timeout=30s;
        }

        server {
              listen 80;

              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;
              }
        }
}
