# 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
