Træfɪk is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy. Træfik integrates with your existing infrastructure components (Docker, Swarm mode, Kubernetes, Marathon, Consul, Etcd, Rancher, Amazon ECS, ...) and configures itself automatically and dynamically. Telling Træfik where your orchestrator is could be the only configuration step you need to do.
Grab a sample configuration file and rename it to traefik.toml. Enable docker provider and web UI:
################################################################
# API and dashboard configuration
################################################################
[api]
################################################################
# Docker configuration backend
################################################################
[docker]
domain = "docker.local"
watch = trueStart Træfɪk:
docker run -d -p 8080:8080 -p 80:80 \
-v $PWD/traefik.toml:/etc/traefik/traefik.toml \
-v /var/run/docker.sock:/var/run/docker.sock \
traefikStart a backend server, named test:
docker run -d --name test containous/whoamiAnd finally, you can access to your whoami server throught Træfɪk, on the domain name {containerName}.{configuredDomain}:
curl --header 'Host: test.docker.local' 'http://localhost:80/'

The web UI http://localhost:8080 will give you an overview of the frontends/backends and also a health dashboard.
