Node-RED SSL reverse proxy w/ Google Oauth

VinistoisR · 2 May 2020 18:12

Ok, try now. I forgot the config declaration in the stack. I don't think you did anything wrong. Thanks for spotting the typo! Btw I load in all my configs through the portainer UI, which only has one field for name, there isn't a separate filename. If you are still having troubles, try that way. I'll work on converting that toml so we can just have it in the static labels, instead of a separate file. I just found it easier at the time to copy the toml into a config.

You've probably deduced by now that .toml files are kind of the same as attaching labels to traefik in the compose file, it's two ways to do the same thing, just with different syntax.

Notice this in the traefik config:

      - "--providers.file.directory=/etc"
      - "--providers.file.watch=true"

That means you can drop any valid toml file into /etc/ in the container and traefik will pick it up on the fly. I use config files to get them there, you can just as easily bind files into /etc/ if you prefer. This is useful for adding services behind traefik that aren't even on your docker host. So if you already have some kind of service with no ssl on your network, a quick toml definition put into /etc/ will proxy it as if it were a docker service, without even restarting anything.

Great, thanks. Much better now, I have got as far as getting the staging certificate (and probably the real one but it hasn't worked its way to the browser yet. However, I am seeing, in the log

time="2020-05-02T21:19:34Z" level=error msg="Router defined multiple times with different configurations in [oatraefik-nodered-oox0sjblssej3pcvdh9kq71zc oatraefik-traefik-49q9e9v3d1bo3bge2lohvt75r]" providerName=docker routerName=traefik

It's getting late here now, so have to leave it for the moment.

VinistoisR · 2 May 2020 23:56

silly mistake on my end. My error was at the bottom of the node-red service declaration, I referenced the traefik router instead of the node-red router.

Colin · 3 May 2020 10:05

Excellent, it is all working now.
One minor points, the oauth service has restart: always, it should be using restart_policy. Should it be set to on-failure as for node-red or left at default (which is any I think) as for traefik?

Also one issue, which may be normal behaviour, with the logs on debug I see the log below, repeated about every 15 seconds, as if something is repeatedly restarting. Though as I said, this may be normal.

That's normal, just set it to INFO.

Colin · 3 May 2020 12:29

Great, thanks.
Mosquitto next, plus working out how to git clone into the node-red container as it is built.

Colin · 3 May 2020 15:36

I am struggling here, I can't work out how to get Traefik to route mqtt to mosquitto, and can't find anything in the docs to help. @VinistoisR, you mentioned mqtt earlier in the thread, have you used Traefik for this or is your mqtt not exposed to the internet?

VinistoisR · 3 May 2020 17:08

I use vernemq through traefik. Tcp routers are new in traefik, you'll need to get familiar with the docs.

Colin · 3 May 2020 19:18

OK, thanks. So much to learn, so little time for learning.
I will report back if I achieve success.

VinistoisR · 3 May 2020 21:06

The reason I use VerneMQ is it gives me zero trouble doing mqtt over wss (secure websocket) via traefik. It's the most basic config - just copy the labels from the nodered service and change all the "nodered" into "mqtt", and you'll be able to make websocket connection to:

wss://mqtt.yourdomain.co:443/mqtt

... Without messing with any cert files at all.

Put it in the same stack as nodered and then from nodered you can connect to mqtt:1883.

Colin · 3 May 2020 21:23

Do I put 1883 in
"traefik.http.services.mqtt.loadbalancer.server.port=1883"?

VinistoisR · 3 May 2020 21:52

No, you can't mqtt into an http port. Traefik http routers can only shuttle packets from http(s) entry points to http(s) backends. Mqtt is a TCP protocol, so you either need to use a TCP router, or publish the mqtt port (1883) and bypass traefik for mqtt connections.

If you use VerneMQ or another broker that supports mqtt over wss, then you can use traefik for that. Use your "websecure" entrypoint just like any other web service, and for loadbalancer.server.port, use whatever you have set as the wss port. IIRC VerneMQ listens on 8080 if you don't specify any different. A small gotcha with VerneMQ is you have to hit the /mqtt path, so your Traefik rule needs to catch that:

#VerenMQ Secure Websocket Proxy
       - "traefik.http.routers.vernemq_wss.rule=Host(`vernemq.mydomain.net`) && PathPrefix(`/mqtt`)"  # detect mqtt over websockets
       - "traefik.http.routers.vernemq_wss.entrypoints=websecure"
       - "traefik.http.routers.vernemq_wss.tls=true"
       - "traefik.http.routers.vernemq_wss.tls.certresolver=letsencryptresolver"
       - "traefik.http.routers.vernemq_wss.service=wss"
       - "traefik.http.services.wss.loadbalancer.server.port=8080"
       - "traefik.http.routers.vernemq_wss.middlewares=sslheader@docker"

Colin · 4 May 2020 08:41

I have got it working with vernemq and wss with some additional input from the second post on the link below, obviously posted by a very knowledgeable and helpful guy
There are a couple of small issues that I might need to come back on but it is basically working.
https://gist.github.com/Dacturne/80f09adc83080cd3b17eacf22baaf968

Colin · 5 May 2020 08:13

In case anyone is interested below is what is working for me with Vernemq over secure web sockets. To access it from a remote mqtt client such as node red, reference the server as wss://vernemq.mydomain.net:443/mqtt. To reference it locally from node red running in the same Traefik stack use Server vernemq Port 1883.

Many thanks again to @VinistoisR for his help getting this working.

@VinistoisR, with the oauth google authorisation, how does one logout? I can't see any reference to that in the docs.

VinistoisR · 5 May 2020 20:21

Just log out of your Google account. Or, you can click the padlock in your browser, usually brings up the set cookies with a button "remove". Once the cookie is removed you can refresh the page and it will ask you to log back in.

Colin · 6 May 2020 07:54

That works, thanks.

Colin · 10 May 2020 13:25

@VinistoisR how should I restart node-red when the need arises? I tried restarting the container in Portainer and everything looked ok, including the node red startup log, but I can't access it, I get 404 not found. The only way I have found so far is by doing a full stack deploy.
