Pihole (on a remote host)

[fabricesemti80]

Hi There!

Great guide, thanks for the effort!

I have one problem though.

I try to forward some services (for starters I am trying to do this with PiHole) to another (k8s) server on my network, but I am struggling to make this work.

My Docker server runs on 192.168.0.21, the k8s hosts are on 192.168.0.11 - .13, and the loadbalancer range for k8s is 192.168.0.240 - .250. PiHole is on 192.168.0.242, and it is accessible within my network.

I have this configuration in the the docker compose:

`...

Cloudflare-Companion - Automatic CNAME DNS Creation

cf-companion:
container_name: cf-companion
image: tiredofit/traefik-cloudflare-companion:latest
# security_opt:
# - no-new-privileges:true
restart: unless-stopped
networks:
- socket_proxy
#depends_on:
# - socket-proxy
environment:
- TIMEZONE=$TZ
- TRAEFIK_VERSION=2
#- CF_EMAIL=$CLOUDFLARE_EMAIL
- CF_TOKEN=$CLOUDFLARE_API_TOKEN
- TARGET_DOMAIN=$DOMAINNAME0
- DOMAIN1=$DOMAINNAME0
- DOMAIN1_ZONE_ID=$CLOUDFLARE_ZONEID # Copy from Cloudflare Overview page
- DOMAIN1_PROXIED=TRUE
- DOCKER_HOST=tcp://socket-proxy:2375
secrets: # not working
- cloudflare_api_token
labels:
# Add hosts specified in rules here to force cf-companion to create the CNAMEs
# Since cf-companion creates CNAMEs based on host rules, this a workaround for non-docker/external apps
# - "traefik.http.routers.cf-companion-rtr.rule=Host(mox.$DOMAINNAME0) || Host(pwt.$DOMAINNAME0) || Host(webmin.$DOMAINNAME0) || Host(shell.$DOMAINNAME0)"
- "traefik.http.routers.cf-companion-rtr.rule=Host(plex.$DOMAINNAME0) || Host(pihole.$DOMAINNAME0)" `

 (plex router does not work either, but for now I am focusing on PiHole)
 
 the app-pihole.toml rule is set as this:

[http.routers] [http.routers.pihole-rtr] entryPoints = ["https"] middlewares = ["chain-authelia", "pihole-add-admin"] rule = "HostHeader(pihole.<mydomain.com>`)"
service = "pihole-svc"
[http.routers.pihole-rtr.tls]
certresolver = "dns-cloudflare"

[http.middlewares]
[http.middlewares.pihole-add-admin.addPrefix]
prefix = "/admin"

[http.services]
[http.services.pihole-svc]
[http.services.pihole-svc.loadBalancer]
passHostHeader = true
[[http.services.pihole-svc.loadBalancer.servers]]
url = "http://192.168.0.242:80" # or whatever your external host's IP:port is`

I can confirm the pihole.<mydomain.com> DNS entry gets created, but when I would browse to that address, I get HTTP error 500...

Any chance you can advise what am I missing?

Thanks,
Fabrice

Hi @fabricesemti80 I don't think your issue report is actually an 'issue' with the software. See #277 and perhaps consider closing this (none) issue?

Hi. Sorry this has been a while. Long non-relevant. Closing
