Presenter: Jimmy Cuadra Title: kaws: Deploying Kubernetes Clusters using AWS, CoreOS, Terraform, and Rust Abstract: Kubernetes is complex software and setting up a new cluster can be difficult. While there are easy approaches like Google Container Engine, you may want to customize your cluster in various ways, or simply understand how it all works. A great way to do this is to define your cluster as code using Terraform. In this talk, you'll learn about kaws, a tool written in the Rust programming language that brings together several platforms and tools to automate the creation and management of secure, highly available Kubernetes clusters.

2. KUBERNETES IS THE FUTURE

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

5. Reproducible infrastructure

7. 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"
}

8. $ terraform plan

9. + aws_instance.example
ami: "" => "ami-043a5034"
availability_zone: "" => "<computed>"
instance_type: "" => "m1.small"
key_name: "" => "<computed>"
private_dns: "" => "<computed>"
private_ip: "" => "<computed>"
public_dns: "" => "<computed>"
public_ip: "" => "<computed>"
security_groups: "" => "<computed>"
subnet_id: "" => "<computed>"
