Why do my configurations of Grafana, Docker and Traefik not route my requests to Grafana's frontpage? - docker

I am new to traefik and am trying to set up my containers to be reverse-proxied by traefik at the moment. It all worked fine while using traefik.frontend.rule=Host:grafana01.mydomain.com for routing requests to grafana01.mydomain.com, but due to infrastructural issues within our network I'd rather use traefik.frontend.rule=Path:/grafana01/ to redirect to mydomain.com/grafana01. Yet for some reason it does not work.
My traefik.toml file as well as my two docker-compose.yml files for traefik and grafana, respectively:
#Traefik Global Configuration
debug = false
checkNewVersion = true
logLevel = "ERROR"
#Define the EntryPoint for HTTP and HTTPS

I'd appreciate any help!

Changing traefik.frontend.rule=Path:/grafana01/ to
traefik.frontend.rule=PathPrefixStrip:/grafana01 as well as adding
GF_SERVER_ROOT_URL=%(protocol)s://%(domain)s/grafana01
did the trick for me.

Traefik cannot Issue Lets Encrypt Cert for gitlab container on different port

im running a gitlab-ee docker container behind a traefik v1 docker container. My gitlab is supposed to run on the domain gitlab.dev.example.com:65443 the port 65443 is being forwarded to 443 on my server within my router (i have other stuff running on my 443 and 80 port). my traefik dashboard is running on traefik.dev.example.com:65443/dashboard/
Now when i want to get a lets encrypt certificate with traefik it tries to get it for the domain gitlab.dev.example.com and fails with "Unable to obtain ACME certificate for domains "gitlab.dev.example.com" [...]"
if i visit https://gitlab.dev.example.com:65443 it opens my gitlab container but with the "Traefik Default Cert". I cannot push or pull from these gitlab repositories because the SSL Certificates are self signed hence why i want to get a lets encrypt one.
i swapped out the actual domain with "example.com" obviously
my traefik.toml:
debug = false
logLevel = "ERROR"
defaultEntryPoints = ["https", "http"]
[web]
address = ":80"
[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "traefik.dev.example.com" //swapped the url out
watch = true
exposedByDefault = false
# Force HTTPS
[entryPoints]
[entryPoints.http]
address = ":80"
[entryPoints.http.redirect]
entryPoint = "https"
[entryPoints.https]
address = ":443"
[entryPoints.https.tls]
# Enable retry sending a request if the network error
[retry]
# Let's encrypt configuration
[acme]
email="e#mail.com" //swapped the email out

Traefik - local https not working. Unable to reach server

I tried to set up reverse-proxy using traefik for one my docker-services. When I run the services, in traefik's web UI I can see the mapping but only for http eventhough I have specified https in traefik.toml file. I am also not able to access my services directly. All the services are in the same network. So I am not sure what is causing this.

Thanks in advance.
Try to add following docker label to your graphql-server service:
traefik.frontend.entryPoints=http,https
I am facing the same problem. I have 'defaultEntryPoints = ["http", "https"]' in traefiks (v1.7) main config defined, but when docker containers come up and register within traefik the frontend is reachable only via HTTP, not HTTPS - unless i define the entrypoints directly via docker labels.

Traefik + Nextcloud results in bad gateway

I have 3 services up and running.
A mariadb & nextcloud instance:
version: '2.1'
volumes:
nextcloud:
db:
services:
db:
image: mariadb
volumes:
- db:/var/lib/mysql
environment:
- MYSQL_ROOT_PASSWORD=my_root_password
- MYSQL_PASSWORD=my_password
- MYSQL_DATABASE=my_database
- MYSQL_USER=my_user
app:
image: nextcloud
restart: always
networks:
- web
- default
ports:
- 9000
labels:
- "traefik.backend=app"
- "traefik.docker.network=web"
- "traefik.frontend.rule=Host:my_host"
- "traefik.enable=true"
- "traefik.port=9000"
- "traefik.default.protocol=http"
networks:
web:
external: true
And a traefik service:
version: '2'
services:
traefik:
image: traefik:1.5.4
restart: always
ports:
- 80:80
- 443:443
networks:
- web
volumes:
- /var/run/docker.sock:/var/run/docker.sock
- /opt/traefik/traefik.toml:/traefik.toml
- /opt/traefik/acme.json:/acme.json
container_name: traefik
networks:
web:
external: true
This traefik instance is using this config file:
debug = false
logLevel = "ERROR"
defaultEntryPoints = ["https","http"]
[entryPoints]
[entryPoints.http]
address = ":80"
[entryPoints.http.redirect]
entryPoint = "https"
[entryPoints.https]
address = ":443"
[entryPoints.https.tls]
[retry]
[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "my_host"
watch = true
exposedByDefault = false
[acme]
email = "my_email"
storage = "acme.json"
entryPoint = "https"
onHostRule = true
[acme.httpChallenge]
entryPoint = "http"
Now when I goto my host, it redirects to HTTPS but then it just displays bad gateway and nothing else. It should display the nextcloud web application. Anyone know why this is happening? I am running the compose files using the docker-compose up -d command.
It might be too late now but I also ran into this issue myself, so posting an answer to what resolved it for me.
Nextcloud exposes port 80 on the container's IP address which Traefik is trying to connect to. So you incorrectly specified the port for 'traefik.port' label. Change it from 9000 to 80.

Traefik won't forward to backend configured with Docker labels

Here's my Traefik configuration:
defaultEntryPoints = ["http", "https"]
[entryPoints]
[entryPoints.http]
address = ":80"
[entryPoints.http.redirect]
entryPoint = "https"
[entryPoints.https]
address = ":443"
[entryPoints.https.tls]
[entryPoints.internal]
address = ":8080"
[entryPoints.traefik]
address = ":8081"
[retry]
[api]
entryPoint = "traefik"
dashboard = true
[file]
[backends]
[backends.traefik]
[backends.traefik.servers.default]
url = "http://127.0.0.1:8081"
[frontends]
[frontends.traefik]
entryPoints = ["internal"]
backend = "traefik"
[frontends.traefik.routes.default]
rule = "Host:localhost;PathPrefixStrip:/traefik;PathPrefix:/traefik"
[docker]
domain = "example.com"
watch = true
exposedbydefault = false
As you can see, I have Traefik dashboard configured to show on localhost:8080/traefik. This works exactly as intended.
I also have very similar configuration for RabbitMQ management UI, set up with docker-compose using labels:
version: '3'
services:
traefik:
image: traefik:alpine
container_name: traefik
ports:
- "80:80"
- "443:443"
- "127.0.0.1:8080:8080"
networks:
- web
- internal
volumes:
- "/var/run/docker.sock:/var/run/docker.sock"
- "./config/traefik/staging.toml:/etc/traefik/traefik.toml"
rabbitmq:
image: rabbitmq:3.7-management-alpine
hostname: rabbitmq
container_name: rabbitmq
networks:
- internal
- default
depends_on:
- traefik
environment:
RABBITMQ_VM_MEMORY_HIGH_WATERMARK: 128MiB
RABBITMQ_ERLANG_COOKIE: temp_cookie_secret
RABBITMQ_NODENAME: rabbit#rabbitmq
volumes:
- "rabbitmqdata:/var/lib/rabbitmq"
labels:
- "traefik.backend=rabbitmq"
- "traefik.docker.network=internal"
- "traefik.frontend.rule=Host:localhost;PathPrefixStrip:/rabbitmq;PathPrefix:/rabbitmq"
- "traefik.enable=true"
- "traefik.port=15672"
- "traefik.protocol=http"
- "traefik.domain=localhost"
networks:
internal:
web:
volumes:
rabbitmqdata
However, this doesn't work: on http://localhost:8080/rabbitmq I get 404 page not found. Traefik dashboard shows that it found my RabbitMQ container and registered rules that are very much like those for Traefik's dashboard:
Where's the mistake here that prevents my setup from working as intended?
