## Requirements
-	[Terraform](https://www.terraform.io/downloads.html) >=0.12.x
-	[Go](https://golang.org/doc/install) 1.18.x (to build the provider plugin)

## Building The Provider

```sh
$ git clone git@github.com:kreuzwerker/terraform-provider-docker
$ make build
```

## Example usage

Take a look at the examples in the [documentation](https://registry.terraform.io/providers/kreuzwerker/docker/2.21.0/docs) of the registry
or use the following example:


```hcl
# Set the required provider and versions
terraform {
  required_providers {
    # We recommend pinning to the specific version of the Docker Provider you're using
    # since new versions are released frequently
    docker = {
      source  = "kreuzwerker/docker"
      version = "2.21.0"
    }
  }
}

# Configure the docker provider
provider "docker" {
}

# Create a docker image resource
# -> docker pull nginx:latest
resource "docker_image" "nginx" {
  name         = "nginx:latest"
  keep_locally = true
}

# Create a docker container resource
# -> same as 'docker run --name nginx -p8080:80 -d nginx:latest'
resource "docker_container" "nginx" {
  name    = "nginx"
  image   = docker_image.nginx.image_id

  ports {
    external = 8080
    internal = 80
  }
}

# Or create a service resource
# -> same as 'docker service create -d -p 8081:80 --name nginx-service --replicas 2 nginx:latest'
resource "docker_service" "nginx_service" {
  name = "nginx-service"
  task_spec {
    container_spec {
      image = docker_image.nginx.repo_digest
    }
  }

  mode {
    replicated {
      replicas = 2
    }
  }

  endpoint_spec {
    ports {
      published_port = 8081
      target_port    = 80
    }
  }
}
```
