1. KAWS Deploying Kubernetes Clusters using AWS, CoreOS, Terraform, and Rust @jimmycuadra
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>"
10. $ terraform apply
11. Provisioning
12. Workflow
13. INTRODUCING KAWS
14. Goals
15. Infrastructure as code
16. Production grade Kubernetes clusters
17. Secure access credentials
18. Shell scripts
20. $ kaws init my-companys-infrastructure $ cd my-companys-infrastructure $ git init
21. $ tree . !"" clusters !"" pubkeys #"" terraform #"" main.tf
22. $ cat terraform/main.tf module "kaws" { source = "github.com/InQuicker/kaws//terraform?ref=v0.1.0" ... }
23. $ kaws key export jimmy@example.com
24. $ tree . !"" clusters !"" pubkeys $ #"" jimmy@example.com.asc #"" terraform #"" main.tf
25. $ kaws cluster create staging \ --ami ami-1234 \ --domain example.com \ --kubernetes-version 1.0.7 \ --instance-size m3.medium \ --ssh-key deployer \ --uid jimmy@example.com \ --zone-id Z1D633PJN98FT9
