go-sleep

go-sleep helps to automatically start cloud instances Google Compute Engine / Amazon EC2 by request (HTTP) and stopping unused instances, after some time.

Here is basic workflow: the go-sleep handles all incoming requests, if instance running, proxy all traffic. Else request start instance and waiting him.

Global

# Port
# Reserved for web API interface
port = ":9090"

# Secret key
# Is passed along with every request to that site in the X-Go-Sleep-Key header
secret_key = "my-secret-key"

# Log level
log_level = "info"

Basic auth

# Group user for basic auth
# Passwords can be encoded in MD5, SHA1 and BCrypt: you can use htpasswd to generate those ones

# [auth]
#  [auth.<group_name>]
#    users = ["<user>:<password>", "<user>:<password>"]

# This example register two groups admins/freelancers with user "test" with password "test"
[auth]
  [auth.admins]
    users = ["test:$apr1$bfLZ0ZMK$CYhTBqS.Yl.V1hbOpHze51"]
  [auth.freelancers]
    users = ["test:$apr1$bfLZ0ZMK$CYhTBqS.Yl.V1hbOpHze51"]

Instance (Google Compute Engine)

# This example register one GCE instance with two hostnames (example.com and www.example.com) on 80/443 port (with TLS)
# Access is limited basic auth (for group "admins")
