Dockerfile

## DynDNS for Docker with Route53
##
## Dynamic DNS counterpart of James Wilder's nginx-proxy for docker:
## [jwilder/nginx-proxy](https://github.com/jwilder/nginx-proxy).
##
## Containerize cli53
## Discover the expected DNS names following the same conventions than jwilder/nginx-proxy
## Generate the DNS A record file and call cli53 to process it
