Pengantar

Setelah sebelumnya saya membahas mengenai Cara Install Terraform pada Rocky Linux 8 | Almalinux 8 , kali ini kita coba mulai membuat infratruktur docker kontainer dengan terraform.

Cara Menggunakan Terraform untuk membangun Kontainer Nginx Docker

Membuat Infrastructur docker

Buat Folder project1

mkdir -p project1
cd project1

Buat file

nano main.tf

terraform {
  required_providers {
    docker = {
      source = "kreuzwerker/docker"
      version = "~> 2.13.0"
    }
  }
}

provider "docker" {}

resource "docker_image" "nginx" {
  name         = "nginx:latest"
  keep_locally = false
}

resource "docker_container" "nginx" {
  image = docker_image.nginx.latest
  name  = "tutorial"
  ports {
    internal = 80
    external = 8000
  }
}

Initial

terraform init
terraform fmt
terraform validate
terraform apply
terraform show
terraform state list

akses browser

localhost:8000

Cara Mengubah Infrastructur

Buat folder aplikasi
Kemudian masuk ke folder aplikasi
Kemudian buat file main.tf

nano main.tf

terraform {
  required_providers {
    docker = {
      source  = "kreuzwerker/docker"
      version = "~> 2.13.0"
    }
  }
}

provider "docker" {}

resource "docker_image" "nginx" {
  name         = "nginx:latest"
  keep_locally = false
}

resource "docker_container" "nginx" {
  image = docker_image.nginx.latest
  name  = "tutorial"
  ports {
    internal = 80
    external = 8000
  }
}

Initial

terraform init
terraform apply

Edit main.tf

external = 8080

Simpan Perubahan

terraform apply
terraform show

Destroy Infrastructur

Destroy

terraform destroy

Menambahkan Variables

Buat folder aplikasi
Kemudian masuk ke folder aplikasi
Kemudian buat file main.tf

nano main.tf

terraform {
  required_providers {
    docker = {
      source  = "kreuzwerker/docker"
      version = "~> 2.13.0"
    }
  }
}

provider "docker" {}

resource "docker_image" "nginx" {
  name         = "nginx:latest"
  keep_locally = false
}

resource "docker_container" "nginx" {
  image = docker_image.nginx.latest
  name  = "tutorial"
  ports {
    internal = 80
    external = 8080
  }
}

Buat file variables.tf

nano variables.tf

variable "container_name" {
  description = "Value of the name for the Docker container"
  type        = string
  default     = "ExampleNginxContainer"
}

Edit main.tf

name  = "tutorial"
ubah jadi
name  = var.container_name

Apply konfig

terraform apply
terraform apply -var "container_name=YetAnotherName"

Menambahkan Query Data dengan Outputs

Buat folder project1
masuk ke project1
Tambahkan main.tf dan variables.tf

# main.tf

terraform {
  required_providers {
    docker = {
      source  = "kreuzwerker/docker"
      version = "~> 2.13.0"
    }
  }
}

provider "docker" {}

resource "docker_image" "nginx" {
  name         = "nginx:latest"
  keep_locally = false
}

resource "docker_container" "nginx" {
  image = docker_image.nginx.latest
  name  = var.container_name
  ports {
    internal = 80
    external = 8080
  }
}

# variables.tf

variable "container_name" {
  description = "Value of the name for the Docker container"
  type        = string
  default     = "ExampleNginxContainer"
}

Apply

$ terraform init
$ terraform apply

Buat file outputs.tf

output "container_id" {
  description = "ID of the Docker container"
  value       = docker_container.nginx.id
}

output "image_id" {
  description = "ID of the Docker image"
  value       = docker_image.nginx.id
}
