If you'd like to experiment with [Terraform](https://www.terraform.io) on 
macOS locally, a great provider for doing so is the
[Docker provider](https://www.terraform.io/docs/providers/docker/index.html).
You can get set up in a few simple steps, like so:

## 1. Install Docker

[Install Docker for Mac](https://docs.docker.com/docker-for-mac/install/) if
you have not already.

## 2. Install Terraform

Grab the latest Terraform for macOS from
[releases.hashicorp.com](https://releases.hashicorp.com/terraform/)
and place the `terafform` binary somewhere in your `PATH` or you can install
with Homebrew:

```
brew install terraform
```

## 3. Configure, Plan & Apply!

Start with a basic NGINX Docker container definition in a minimal Terraform
configuration — create a `main.tf` file, and add this to it:

```hcl
# Configure Docker provider and connect to the local Docker socket
provider "docker" {
  host = "unix:///var/run/docker.sock"
}

# Create an Nginx container
resource "docker_container" "nginx" {
  image = "${docker_image.nginx.latest}"
  name  = "enginecks"
  ports {
    internal = 80
    external = 80
  }
}

resource "docker_image" "nginx" {
  name = "nginx:latest"
}
```

Save the file, then apply the configuration:

```
terraform plan
```

If the plan is good and without error, apply it:

```
terraform apply
```

Check to see that the container is running:

```
docker ps -a
```

The output should have something like this:

```
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                         NAMES
41911ec0df6f        6b914bbcb89e        "nginx -g 'daemon ..."   5 seconds ago       Up 4 seconds        0.0.0.0:80->80/tcp, 443/tcp   enginecks
```

Now visit [http://localhost](localhost) in your browser and you should see
the **Welcome to nginx!** default page!
