Traefik 2.2 + cloudflare

avico · April 11, 2020, 1:11pm

Following this post :

I tried to configure by same dynamic approach ,
where :
Need the dashboard be accessible internally on :8888
and from outside https://traefik.mydomain.com
same for HA - internally on :8123
and outside https://ha.mydomain.com
at current :
not able to reach the traefik dashboard /HA from internally or from outside network.

I configure my domain in CF as following:

docker-compose

version: "3.3"
networks:
  rev_traefik_proxy:
    external: true

services:

Thanks @ldez

Traefik dashboard open on
http://192.168.1.112:8888/dashboard/#/

HA usually open with http://192.168.1.112:8123
but currently it is not.

Also check from same network ,
None of below connecting:
https://traefik.mydomain.com

http://traefik.mydomain.com

http://ha.mydomain.com

https://ha.mydomain.com

getting ERR_TOO_MANY_REDIRECTS

On access.log i do see many attempts (although i hit it once):

@ldez ,

wooo hooo .... Got progress:)

so if anyone face situation with "ERR_TOO_MANY_REDIRECTS" --> it
coming actually from CF and not traefik.
it required to change the SSL/TLS setting from "Flexible"
which coming as default setting and encrypts traffic between the browser and CF,
to --> "Full" which encrypts end-to-end, using a self signed certificate on the server.

Now i'm to longing with :
https://traefik.mydomain.com

http://traefik.mydomain.com

http://ha.mydomain.com

https://ha.mydomain.com

Can i also configure traefik so i be able to login to HA
with host-ip:8123 ?

I map a non-docker application which access from http://192.168.1.112:8089,
I tried adding the traefik labels but didn't work:

      #qnap
#      traefik.http.routers.qnap.rule: Host(`qnap.mydoamin.com`)
#      traefik.http.routers.qnap.entrypoints: websecure
#      traefik.http.services.qnap.loadbalancer.server.port: 8089

The only option i manage to get it work is by adding dynamic.yaml which as I understand from u - less recommend as it breaks the dynamic approach ,

http:
  routers:
    service-router:
      entryPoints:
        - websecure
      service: service-qnap
      rule: Host(`qnap.mydomain.com`)
      tls:
        certResolver: myresolver
  services:
    service-qnap:
      loadBalancer:
        servers:
          - url: "http://192.168.1.112:8089"

is there a way adding/mapping a non-docker application to traefik without a separate file?

Thanks a lot @ldez - u are a saver!

avico · April 14, 2020, 9:39am

Have some issue with this configuration ,
now when im connecting to HA (internally from some network)
I can't use any of host-ip but the dns names ,
it means that i go out the internet and go back my server.

Is it possible to keep this configuration but allow some internal IP to access the HA?

avico · April 15, 2020, 4:36pm

Anybody can assist with it please?

Is there an option to access HA also with localhost:8123
(when I connect from same network)?
