Demo: Reverse Proxy

Automatic wiring using Traefik:

docker-compose up -d
IP=$(
  docker-compose ps -q proxy | \
      xargs docker inspect \
          -f ''
)

Use network_mode: host to avoid port publishing

Testing access:

curl --silent --resolve hub.dille.io:80:$IP \
    http://hub.dille.io

curl --silent --resolve registry.dille.io:$IP \
    http://registry.dille.io/v2/
