Traefik as a simple Http Reverse Proxy not working

Question

I am using Traefik as HTTP reverse proxy. I have two servers created using spring boot. Both servers are working properly on port 8081 and 8082

Traefik web UI is visible in port 8080.

What I wanted is to redirect http://localhost:7070/ to http://localhost:8081/ or http://localhost:8082/

traefik.toml config file

loglevel="INFO"

defaultEntryPoints = ["http"]

[entryPoints]
 [entryPoints.http]
 address = ":7070"

[file]

[frontends]
 [frontends.frontend1]
 backend = "backend1"
  [frontends.frontend1.routes.test_1]
  rule = "Host: localhost"

[backends]
  [backends.backend1]
  [backends.backend1.LoadBalancer]
  method = "drr"
  [backends.backend1.healthcheck]
  path = "/app/health"
  interval = "60s"

[backends.backend1.servers.server1]
url = "http://127.0.0.1:8081"
weight = 1

[backends.backend1.servers.server2]
url = "http://127.0.0.1:8082"
weight = 1
[api]
[ping]
[docker]

console output

When I load http://localhost:7070/ from the browser it gives

Service Unavailable

when I go to Traefik health dashboard it displays

Can anybody tell me what I am doing wrong here? I went through a few articles but unable to find the correct answer.

Answer 1

I suppose your are running Træfik in a container.

127.0.0.1 -> localhost inside the container, not in your local machine.
