Nginx + Docker subfolder configuration

[olegberman]

Description:

Not able to get Rocket.chat to work in a subfolder https://domain.com/chat with Docker + Nginx. Can anyone possibly share their working configuration?

Expected behavior:

Chat to load as usual.

Actual behavior:

These are errors that I'm getting (this is the closest I got to get it running):

Server Setup Information:

• Using CentOS
• Running recent Rocket.chat release in Docker (with docker-compose)

Configs

nginx.conf

  # the nginx server instance
  server {
      server_name domain.com;

      location / {
         # ... different app
      }

	location /chat/ {
            # ... some irrelevant stuff

           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://0.0.0.0:3000/;
           proxy_redirect off;
	}

        # found this hack in one of the issues to make /sockjs endpoint work
        location /sockjs {
        	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://0.0.0.0:3000/sockjs;
        	proxy_redirect off;
        }

    listen 443 ssl; # managed by Certbot
    ... irrelevant certbot stuff
}

Additional context

Hosting on the subdomain working just fine!

Now it looks like Rocket.chat tries to call /api path, and I can't add the same hack as location /sockjs { as I have an API for a different app there. It should be calling /chat/api and /chat/sockjs ideally.

Here is more configuration from MongoDB:

rs0:PRIMARY> db.rocketchat_settings.find({ "_id" : "CDN_PREFIX"})
> { "_id" : "CDN_PREFIX", "value" : "" }

rs0:PRIMARY> db.rocketchat_settings.find({ "_id" : "Site_Url"})
> { "_id" : "Site_Url", "value" : "https://domain.com/chat", "type" : "string", "i18nDescription" : "Site_Url_Description", "public" : true, "group" : "General", "packageValue" : "http://localhost:3000", "valueSource" : "packageValue", "hidden" : false, "blocked" : false, "sorter" : 1, "i18nLabel" : "Site_Url", "autocomplete" : true, "ts" : ISODate("2018-07-13T19:31:01.211Z"), "_updatedAt" : ISODate("2018-07-13T19:31:01.211Z") }

I also tried updating these values CDN_PREFIX and Site_Url, and changing around the nginx config but nothing helps. Has anyone managed to get Docker+nginx+sudomain combination working?

P.S. I've read through #2655, #4546, #8487 and none of these provide a solution.
Also I read https://rocket.chat/docs/installation/manual-installation/running-in-a-sub-folder/
and https://rocket.chat/docs/installation/manual-installation/configuring-ssl-reverse-proxy/

For me this works:

        location /rocketchat {
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forward-Proto http;

            proxy_set_header X-Nginx-Proxy true;
            proxy_pass http://127.0.0.1:3000/rocketchat;
            proxy_redirect off;
        }

And my docker-compose.yml

db:
  image: mongo
  volumes:
    - ./data/runtime/db:/data/db
    - ./data/dump:/dump
  command: mongod --smallfiles

rocketchat:
  image: rocketchat/rocket.chat:latest
  environment:
    - MONGO_URL=mongodb://db:27017/rocketchat
    - ROOT_URL=https://127.0.0.1/rocketchat/
    - Accounts_UseDNSDomainCheck=False
  links:
    - db:db
  ports:
    - 3000:3000

Thank you @angusvb! Will try this.

[olegberman]

@angusvb Thank you, this worked for the most part. I had to also add:

	location /file-upload/ {
           proxy_pass http://127.0.0.1:3000/chat/file-upload/;
        }

into the Nginx config to get file uploads working properly (and to not further modify Rocket chat's code).

[angusvb]

@olegberman thx, that is the part that I was still figuring out!

[olegberman]

@angusvb can you confirm you're also having this issue integrating Zapier? #11509

[edwardando]

@angusvb thanks for posting your config, got me off the ground!

@angusvb This saved my day, thanks a lot for sharing! 🙏
