Terraform issue on macOs - terraform

Question

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

Issue has been resolved, solution available in this link

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.
