I have chosen other docker network to deploy it. I could show my method here:

As mentioned above, my frontend docker container can't connect websocket with the backend docker container but the http connection does well.

Instead, I used host network on the frontend and backend container. And then I used nginx to proxy the websocket and the frontend page. The nginx config is following:



# 非强制重定向https
server {
    listen 443 ssl; #侦听443端口，用于SSL
    server_name YOUR_SERVERNAME;  # 自己的域名
    ssl_certificate /etc/nginx/cert/XXX.pem;
    ssl_certificate_key /etc/nginx/cert/XXX.key;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;

    location / {
        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;
        proxy_pass http://127.0.0.1:3000;
    }
    location /ws/ {
        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;
        proxy_pass http://127.0.0.1:8000;
    }
}

BUT I still think it is not elegant. I don't know why I could not access the bakend by websocket but I could access the backend by http when using the same host: http://backend:8000.

If someone could offer more info about deployment, I would pretty appreciate.
