Hello Terraform
- 2. Agenda • Motivação • O que é Terraform? • Qual o plano? • Demo • Mais funcionalidades
- 3. Motivação Evitar o Next > Input > Next > Input > Finish (WRONG!)
- 4. Motivação • Evitar a repitição • Evitar o erro humano • A preguiça fala mais “auto” • Entrar na moda de *aC
- 5. Motivação hype := “2018 é * as Code” Infrastructure Environment Architecture CI/CD Hype Driven Development (HDD)
- 6. O que é Terraform? Terraform é uma ferramenta para construção, alteração e versionamento de infraestrutura com segurança e eficiência “ ” Definição
- 7. O que é Terraform? Alinhamento • Permite definir recursos de maneira declarativa • Não é uma API Abstraction Layer • Cada cloud tem seus próprios recursos
- 8. O que é Terraform? ‣‣ Ferramenta criada pela HashiCorp Open Source
- 9. O que é Terraform? ‣‣ Escrita em Go
- 10. ‣‣ Suporta vários provedores O que é Terraform? e muito mais
- 11. O que é Terraform? ‣‣ Suporta vários provedores provider "aws" { region = "us-west-1" }
- 12. O que é Terraform? ‣‣ Permite codificar sua infraestrutura em arquivos de configuração $ ls main.tf variables.tf.json terraform.tfstate Extensões Descrição *.tf e *.tf.json Arquivos de configuração *.tfstate, *tfstate.lock Arquivos de estado .terraform/ Arquivos de plugins
- 13. O que é Terraform? ‣‣ Codificação em HCL, syntax yaml/json hybrid resource "aws_instance" "web" { count = 5 ami = "ami-408c7f28" instance_type = "t1.micro" } HCL (HashiCorp Configuration Language)
- 14. O que é Terraform? ‣‣ HCL é construída em torno de dois conceitos principais: blocos¹ e atributos² resource "aws_instance" "web" { count = 5 ami = "ami-408c7f28" instance_type = "t1.micro" } HCL (human-friendly) { "resource": { "aws_instance": { "web": { "count": 5, "ami": "ami-408c7f28", "instance_type": "t1.micro" } } } JSON (verbose, doesn't support comments) equivalente ¹ ² main.tf main.tf.json
