KUBERNETES IS THE FUTURE

$ export KUBERNETES_PROVIDER=aws $ curl -sS https://get.k8s.io | bash

Reproducible infrastructure

resource "aws_elb" "frontend" { name = "frontend-load-balancer" listener { instance_port = 8000 instance_protocol = "http" lb_port = 80 lb_protocol = "http" } instances = ["${aws_instance.app.*.id}"] } resource "aws_instance" "app" { count = 5 ami = "ami-043a5034" instance_type = "m1.small" }

$ terraform plan
