HPR - Hot Potato Router

######## dynamic reverse proxy

How it works?

HPR receives a connection from interwebs, looks for http backends on Redis for a given vhost and proxy the connection among all backends.

Config:

hpr.conf

hpr:
  http_addr: :80                 # bind address
  https_addr:                    # https_addres
  cert_file:                     # cert file for https
  key_file:                      # key file for https
  probe_interval: 50             # seconds between probes
  db_backend: redis              # backend type

redis:
  server_list: 127.0.0.1:6379    # list of redis servers to connect

Cli:

hprctl

$ hprctl -h
Hot Potato Router Control

Usage:
  hprctl add <vhost> <backend_ip:port> [--weight=<n>]
  hprctl del <vhost> <backend_ip:port> [--weight=<n>]
  hprctl show <vhost>
  hprctl list

Args:
  add           add a new vhost and backend
  dell          del a vhost and a backend
  show          show all backends from a given vhost
  list          list all vhosts

Options:
  -h --help     Show this screen.
  --version     Show version.
  --weight=<n>  Weight in wrr [default: 1].

$ hprctl add hpr.martinez.io 127.0.0.1:8080
$ hprctl add hpr.martinez.io 127.0.0.1:8081
$ hprctl show hpr.martinez.io
:: vhost [ hpr.martinez.io ]
-- backend 127.0.0.1:8080 weight=1
-- backend 127.0.0.1:8081 weight=1

$ hprctl list
:: vhost [ hpr.martinez.io ]

Depends:

• go-redis - https://github.com/fiorix/go-redis.git
• gdocopt - https://github.com/docopt/docopt.go

Todo:

• Improve the database support adding more backends
• Add more load balancing algorithms
• Implement the api on hpr and stop calling direct the database
