Introduction to Terraform 2015/4/17 @ HDE MTS #11 TANABE Ken-ichi
Terraform, it’s HashiCorp’s product
Terraform, it’s HashiCorp’s product • Vagrant (written in Ruby) Programmable
Virtual Machine Frontend • Packer (written in Go) Programmable Machine Image Builder • Consul (Yes, Go!) Distributed KVS, Service Discovery, etc • and Terraform (Yes, Go!) Programmable IaaS
Documentation • Good Docs but… • Spend much time •
Click, Click, Click • Not repeatable • CloudFormation?
CloudFormation • JSON nightmare… • Repeatable • Not maintainable •
Not intuitive at ALL • No dry-run
Terraform comes to the rescue • No JSON! • Simple,
easy-to-use DSL • Built-in dry-run feature • Not only for AWS but for GCP, Heroku, ... • Calculate dependencies on behalf of us • Everything is in version control • No migration tool for now
Seeing is believing 百聞は一見にしかず • Live Demonstration • VPC •
Subnet • Security Group • ELB • EC2
