Terraform issue on macOs

I started to learning terraform, I have installed terraform and docker desktop on my macbook. I am following the quick start tutorial and got below error.

ERROR

╷
│ Error: Error pinging Docker server: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
│
│   with provider["registry.terraform.io/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
      }
    }

Based on the provider documentation [1] (as the error describes as well), you need to switch to the following:

terraform {
   required_providers {
     docker = {
       source  = "kreuzwerker/docker"
       version = "~> 2.22.0"
      }
    }
}
    
provider "docker" {}

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

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

The example from the tutorial is using a very old version of Docker provider. When you make these changes, make sure to run terraform init -upgrade prior to running terraform plan or terraform apply.
