I am new to AWS and new with Traefik too. I am having a lot of trouble trying to remove the need of port especification in a application I am developing.
When I hit http://api-landingpage.cayama.com.br/ it give`s me an 404 page error, but when I try http://api-landingpage.cayama.com.br:8001/ it goes to my api correctly.
I hosted my domain in AWS Route53 and I am using docker as a provider.
Here my configurations:
docker-compose.yml: version: "3"
services:
app:
build: .
ports:
- "8001:8001"
command: "npm start"
docker-production.yml:
version: "3"
services:
traefik:
image: traefik
command:
- "--api.insecure=true"
- "--providers.docker=true"
- "--providers.docker.exposedbydefault=false"
- "--entrypoints.web.address=:80"
ports:
- "80:80"
- "8080:8080"
volumes:
- /var/run/docker.sock:/var/run/docker.sock
app:
labels:
- "traefik.enable=true"
- "traefik.http.routers.app.rule=Host(`http://api-landingpage.cayama.com.br/`)"
- "traefik.http.routers.app.entrypoints=web"
I am sure is there a basic thing that I am missing here, can anyone help me please?
I just want to not have to specify, on URL, the port which my application is running.
Thanks guys!
Theoretically, as you said, you shouldn't have to specify the port manually.
I'm not totally sure it's the cause but you are using a full URL instead of a host. Basically you should replace this:
- "traefik.http.routers.app.rule=Host(`http://api-landingpage.cayama.com.br/`)"
With this:
- "traefik.http.routers.app.rule=Host(`api-landingpage.cayama.com.br`)"
If it does not solve your problem you could try using the loadbalancer directive, even if it is theoretically usefull for Docker Swarm, not for Docker (put this in your app service):
- "traefik.http.services.app.loadbalancer.server.port=8001"
Then if it's still not working enable debugging and look for errors in the logs.
In order to enable debugging, add this to your Traefik service in the command section:
- --log.level=DEBUG
