Olá!

Quem acompanha meu blog sabe que eu estou escrevendo um livro sobre DevOps para um editora indiana, um dos últimos capítulos que escrevi vou sobre Terraform e GCP, então resolvi pegar um pedaço e compartilhar com vocês aqui.

Vamos lá! Já estou considerando que você tem o Terraform instalado e a conta no GCP criada. Então o primeiro passo é acessar o console, depois IAM & Admin e criar uma Service Account com o nome terraform. Essa imagem mostra o passo a passo descrito na linha anterior

Será pedido para que você selecione uma Role, que é a configuração responsável por definir os recursos que a sua Service Account pode gerenciar, nesse caso eu selecionei Compute Admin.

Prossiga com a criação, gere uma chave e salve no formato JSON. Essa imagem mostra o passo a passo descrito na linha acima também

Faça o download do arquivo.json, pois ele será necessário para fazer a autenticação entre o Terraform e o Console do Google Cloud. Eu criei um diretório chamado ProductionInfrastructure onde eu vou salvar os arquivos:

PS C:\Users\1511 MXTI> mkdir ProductionInfrastructure                                                                                                                      

    Directory: C:\Users\1511 MXTI


Mode                LastWriteTime         Length Name
----                -------------         ------ ----
d-----        5/10/2020  12:07 PM                ProductionInfrastructure


PS C:\Users\1511 MXTI> cd .\ProductionInfrastructure\                                                                                                                      PS C:\Users\1511 MXTI\ProductionInfrastructure>

Dentro dele crie um arquivo chamado infrastructure.tf e coloque o arquivo.json que você baixou do google no mesmo diretório. Dentro do infrastructure.tf, cole o seguinte código:

provider "google" {
  credentials = file("terraform_sa.json")
  project     = "alisson-187813"
  region      = "us-east1"
}

Pra que não sabe muito de Terraform, esse trecho de código é respectivo ao provider, que define com quem vamos nos conectar e como vamos nos conectar, nesse caso eu vou me contar com o Google, as minha credenciais de autenticação estão no arquivo terraform_sa.json, a infraestrutura será criada dentro do projeto alisson-187813 na região us-east1.

Esses providers não são baixados nativamente com o Terraform, então você precisa baixa-los para executar o seu código, isso é feito quando usando o comando terraform init.

C:\Users\1511 MXTI\ProductionInfrastructure>   terraform init

Initializing the backend...

Initializing provider plugins...
- Checking for available provider plugins...
- Downloading plugin for provider "google" (hashicorp/google) 3.20.0...

The following providers do not have any version constraints in configuration,
so the latest version was installed.

To prevent automatic upgrades to new major versions that may contain breaking
changes, it is recommended to add version = "..." constraints to the
corresponding provider blocks in configuration, with the constraint strings
suggested below.

* provider.google: version = "~> 3.20"

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

Perfeito, agora vamos definir o trecho de código para a nossa instância.

provider "google" {
  credentials = file("terraform_sa.json")
  project     = "alisson-187813"
  region      = "us-east1"
}

resource "google_compute_instance" "chapter8" {
  name         = "chapter8-instance"
  machine_type = "g1-small"
  zone         = "us-east1-b"
  boot_disk {
    initialize_params {
      image = "ubuntu-1804-bionic-v20200414"
    }
  }
  network_interface {
    network       = "default"
    access_config {
    }
  }
}

Acima definimos que eu vou utilizar o recurso google_compute_instance, que é respectivo as VMs no google, dentro desse recurso temos que definir alguns parametros que definem como a Máquina Virtual será criada, como tamanho da intância, nome que você utilizará para identificar a instancia, a zona em que ela será criada, a imagem, que no caso utilizei o ubuntu e a rede em que a máquina será criada, no access_config, ficou vazio pois utilizaremos as configurações padrão do google, no casso vamos ter um IP Publico por padrão.

Antes de executar o código, sempre utilizamos o comando terraform plan, esse comando vai verificar as diferenças entre o arquivo terraform.tfstate, que pode ser encontrado no mesmo diretório em que você criou o código, porém ele só é criado após você executar o plan. Então ele irá te mostrar as diferenças entre o estado controlado pelo terraform e o seu código/

PS C:\Users\1511 MXTI\ProductionInfrastructure> terraform plan   
Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.

Plan: 1 to add, 0 to change, 0 to destroy.

------------------------------------------------------------------------

Note: You didn't specify an "-out" parameter to save this plan, so Terraform
can't guarantee that exactly these actions will be performed if
"terraform apply" is subsequently run.

Na saíde do comando, pode-se ver que na frente de todos os recursos existe o sinal de mais ( + ). Esse sinal indica que o recurso será criado, no final também pode-se ver essa linha que é muito importante: Plan: 1 to add, 0 to change, 0 to destroy.

Que resume tudo que será feito, mas o mais importante e ver que nada será destruido. Após validar se está tudo como você planejada, utilize o comando terraform apply para executar a criação da infraestrutura.

google_compute_instance.chapter8: Creation complete after 14s [id=projects/alisson-187813/zones/us-east1-b/instances/chapter8-instance]

Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

Muitos atributos da sua instância, só estarão disponíveis após a criação dela, como pro exemplo o IP Público, que é uma informação crucial, pois sem ela não conseguimos acessar a máquina, então vamos pegar esse informaçào utilizando o terraform output.

provider "google" {
  credentials = file("terraform_sa.json")
  project     = "alisson-187813"
  region      = "us-east1"
}

resource "google_compute_instance" "chapter8" {
  name         = "chapter8-instance"
  machine_type = "g1-small"
  zone         = "us-east1-b"
  boot_disk {
    initialize_params {
      image = "ubuntu-1804-bionic-v20200414"
    }
  }
  network_interface {
    network       = "default"
    access_config {
    }
  }
}

output "name" {
  value = google_compute_instance.chapter8.name
}
output "size" {
  value = google_compute_instance.chapter8.machine_type
}
output "public_ip" {
  value = google_compute_instance.chapter8.network_interface[0].access_config[0].nat_ip
}

Veja que no final eu final foi adicionado três novos trechos de códigos, que começam com output, então eu vou retornar o nome da instância, o tamanho dela e o endereço publico.

Como eu não estou modificando nada com relação a instância, eu só estou pegando informações, posso executar o terraform apply direto.

PS C:\Users\1511 MXTI\ProductionInfrastructure> terraform apply                                                                                                              google_compute_instance.chapter8: Refreshing state... [id=projects/alisson-187813/zones/us-east1-b/instances/chapter8-instance]

Apply complete! Resources: 0 added, 0 changed, 0 destroyed.

Outputs:

name = chapter8-instance
public_ip = 104.196.24.122
size = g1-small

Veja que agora após o apply foi mostrado as informações que eu requisitei no output. Mas eu não preciso executar o apply todas as vezes para ter essas informações. Abaixo um exemplo de como é retornada a execução do comando terraform output.

PS C:\Users\1511 MXTI\ProductionInfrastructure> terraform output                                                                                                             name = chapter8-instance
public_ip = 104.196.24.122
size = g1-small

Agora que já temos todas as informações necessárias, podemos adicionar a chave de SSH e acessar a instância. Para adicionar a chave de ssh adicione o código conforme abaixo:

provider "google" {
  credentials = file("terraform_sa.json")
  project     = "alisson-187813"
  region      = "us-east1"
}

resource "google_compute_instance" "chapter8" {
  name         = "chapter8-instance"
  machine_type = "g1-small"
  zone         = "us-east1-b"
  boot_disk {
    initialize_params {
      image = "ubuntu-1804-bionic-v20200414"
    }
  }
  network_interface {
    network       = "default"
    access_config {
    }
  }

  metadata = {
    sshKeys = join("",["alisson:",file("id_rsa.pub")])
  }
}

output "name" {
  value = google_compute_instance.chapter8.name
}
output "size" {
  value = google_compute_instance.chapter8.machine_type
}
output "public_ip" {
  value = google_compute_instance.chapter8.network_interface[0].access_config[0].nat_ip
}

Veja que na parte da instância, foi adicionado um novo atributo chamado metadata e dentro dele temos sshKeys, que recebe uma string seguindo o padrão: usuario:chave_publica Que no caso eu coloquei a minha chave padrão id_rsa.pub, que pode ser encontrada geralmente dentro de ~/.ssh , caso você já tenha gerado ela. Agora vamos executar esse código:

PS C:\Users\1511 MXTI\ProductionInfrastructure> terraform apply                                                                                                            google_compute_instance.chapter8: Refreshing state... [id=projects/alisson-187813/zones/us-east1-b/instances/chapter8-instance]

Plan: 0 to add, 0 to change, 1 to destroy.

Do you really want to destroy all resources?
  Terraform will destroy all your managed infrastructure, as shown above.
  There is no undo. Only 'yes' will be accepted to confirm.
