Cara Menggunakan Terraform untuk membangun Kontainer Nginx Docker

“Cara Menggunakan Terraform untuk membangun Kontainer Nginx Docker”

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.

Provide

• OS Linux Rocky linux
• Sudah install terraform
• Sudah install docker

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
}

• simpan konfig

$ terraform apply
$ terraform output
