Basic Caddy docker-compose config

• can be run on single node setup or in swarm
• recommend to set replicas on 2 or more if deploy in swarm
• default setup requires 2 external networks
  • Services with exposed Ports should be in frontend network
  • Services only accessable for caddy should be in backend network
  • on single host:
    • docker network create frontend
    • docker network create backend
  • on swarm:
    • docker network create --scope=swarm --attachable -d overlay frontend
    • docker network create --scope=swarm --attachable -d overlay backend
