How have a docker-compose to be configured to proxy the dashboard to [myDomain.at/node-red-dashboard] (http://myDomain.at/node-red-dashboard) ?
current path : http://myDomain.at:1880/ui
->
http://myDomain.at/node-red-dashboard
Thanks!
Have you followed along with the excellent recent tutorial and NR, Traefik, SSL and Docker ?
You can see it here

I am using traefik (version 2) to proxy the node-red dashboard and node-red editor.
... but in order to proxy the dashboard I had to append /ui to the URL.
Note that I couldn't get traefik authentication working in combination with the node-red editor or node-red UI authentication. So to fix this I had to disable the node-red editor and node-red ui authentication.
Not sure exactly what your problem is.
I am using traefik (version 2) to proxy the node-red dashboard and node-red editor.
this is working fine.
... but in order to proxy the dashboard I had to append /ui to the URL.
this is working too.
But I want to separate the dashboard from the node-red editor by using another URL. The reason is to expose the GUI without access to the editor.
Example:
traefik shall route
.) editor.myDomain.local to the node-red editor and with /ui to the dashboaed
.) gui.myDomain.local or myDomain.local/gui to the dashboard only
I see. That is a bit more sophisticated setup than mine.
Is it not possible to achieve this by defining a separate traefik "router" for dashboard and another one for editor ?
FYI - here an extract of my docker-compose configuration:
traefik:
build: traefik
container_name: "traefik"
restart: always
command:
#- "--log.level=DEBUG"
#- "--accesslog=true"
- "--api.dashboard=true"
#- "--api.insecure=true"
- "--providers.file.filename=config.yml"
- "--providers.file.watch=true"
- "--providers.docker=true"
- "--providers.docker.exposedbydefault=false"
- "--entrypoints.web.address=:80"
- "--entrypoints.websecure.address=:443"
- "--certificatesresolvers.mytlschallenge.acme.tlschallenge=true"
- "--certificatesresolvers.mytlschallenge.acme.email=${MY_EMAIL_ADDRESS}"
- "--certificatesresolvers.mytlschallenge.acme.storage=/letsencrypt/acme.json"
ports:
- "80:80"
- "443:443"
# The Web UI (enabled by --api.insecure=true)
- "8080:8080"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:ro"
- "./letsencrypt:/letsencrypt"
environment:
# WAN_HOSTNAME is used in traefik config.yml file !
- WAN_HOSTNAME
labels:
- "traefik.enable=true"
# Tell Traefik to use the port opened for the traefik web ui to connect to.
- traefik.http.services.traefik.loadbalancer.server.port=8080
# HTTP (LAN) connection
- "traefik.http.routers.traefik_lan.rule=Host(`traefik.${LAN_HOSTNAME}`)"
- "traefik.http.routers.traefik_lan.service=api@internal"
- "traefik.http.routers.traefik_lan.entrypoints=web"
# HTTPS (WAN) connection
- "traefik.http.routers.traefik_wan.rule=Host(`traefik.${WAN_HOSTNAME}`)"
- "traefik.http.routers.traefik_wan.service=api@internal"
- "traefik.http.routers.traefik_wan.entrypoints=websecure"
- "traefik.http.routers.traefik_wan.tls.certresolver=mytlschallenge"
- "traefik.http.routers.traefik_wan.middlewares=traefik_auth"
- "traefik.http.middlewares.traefik_auth.basicauth.users=${BASIC_AUTH_USER_PASSWORD}"
- "traefik.http.middlewares.traefik_auth.basicauth.removeheader=true"
...
node-red:
build: node-red
#privileged: true
volumes:
- 'node-red-data:/data'
depends_on:
- mqtt
restart: always
environment:
- TZ=Europe/Brussels
env_file:
- .env.node-red
labels:
- "traefik.enable=true"
# HTTP (LAN) connection
- "traefik.http.routers.nodered_lan.rule=Host(`node-red.${LAN_HOSTNAME}`)"
- "traefik.http.routers.nodered_lan.entrypoints=web"
- "traefik.http.routers.nodered_lan.middlewares=traefik_auth"
# HTTPS (WAN) connection
- "traefik.http.routers.nodered_wan.rule=Host(`node-red.${WAN_HOSTNAME}`)"
- "traefik.http.routers.nodered_wan.entrypoints=websecure"
- "traefik.http.routers.nodered_wan.tls.certresolver=mytlschallenge"
- "traefik.http.routers.nodered_wan.middlewares=traefik_auth"
... maybe the "Add Prefix" option have to be used, but how ?
- traefik.http.routers.nodered.middlewares=add-ui
- traefik.http.middlewares.add-ui.addprefix.prefix=/ui
when looking at https://docs.traefik.io/routing/routers/
I would expect something like:
"traefik.http.routers.nodered_wan.rule=(Host(`node-red.${WAN_HOSTNAME}`) && Path(`/ui`))"
Isn't that the wrong way round? I thought @Noschvie wanted a request of http://myDomain.at/node-red-dashboard to be routed to the /ui path in node-red, rather than routing based on a request of /ui?
Yes, the "URL rewriting" is the challenge.
Thanks for clarification!
I focused on the above user request which didn't exclude the use of paths in the URL.
So you can expose the GUI by defining a traefik router for path /ui which won't give you access to the editor.
How to define the traefik router for path /ui ? See snippet below, thanks!
nodered:

container_name: node-red
restart: always
volumes:
- nodered_data:/data
- /etc/localtime:/etc/localtime
environment:
- TZ=Europe/Berlin
labels:
#### Labels define the behavior and rules of the traefik proxy for this container ####
- traefik.enable=true # <== Enable traefik to proxy this container
# The domain the service will respond to
- traefik.http.routers.nodered.rule=Host(`dashboard.mydomain.at`)
# Allow request only from the predefined entry point named "web"
- traefik.http.routers.nodered.entrypoints=web
- traefik.http.routers.nodered.middlewares=add-ui
- traefik.http.middlewares.add-ui.addprefix.prefix=/ui
- traefik.http.routers.nodered.middlewares=auth
# Declaring the user list
- traefik.http.middlewares.auth.basicauth.users=admin:<password>
Oh yes, I see what you mean.
I think for node-red we must use PathPrefix and not Path
I have changed your docker-compose for this.
... one thing to double check (as we use PathPrefix) is to check if this doesn't give access to the node-red editor by using the path dashboard.mydomain.at/ui/.. or dashboard.mydomain.at/ui../
nodered:

container_name: node-red

environment:

#### Labels define the behavior and rules of the traefik proxy for this container ####
- traefik.enable=true # <== Enable traefik to proxy this container
# The domain the service will respond to
- traefik.http.routers.nodered.rule=Host(`dashboard.mydomain.at`) && PathPrefix(`/ui`)
# Allow request only from the predefined entry point named "web"
- traefik.http.routers.nodered.entrypoints=web
# JVA - traefik.http.routers.nodered.middlewares=add-ui
# JVA- traefik.http.middlewares.add-ui.addprefix.prefix=/ui
- traefik.http.routers.nodered.middlewares=auth
# Declaring the user list
- traefik.http.middlewares.auth.basicauth.users=admin:<password>
In the way already suggested by @janvda by adding the path requirement to the Host spec. Isn't it
PathPrefix(`/ui`)
though?
However I think your orginal suggestion with the different urls could also work if in addition you use addPrefix to add the /ui
https://docs.traefik.io/middlewares/addprefix/
I am also wondering if you should not define all middlewares for a specific router on one line instead of 2 lines.
So like this:
- traefik.http.routers.nodered.middlewares=add-ui,auth
I had missed that adddprefix has been included in the second example.
So what isn't working?
with this options it's working.
Perfect, thanks and all the best!
