# Docker Provider

The Docker provider is used to interact with Docker containers and images.
It uses the Docker API to manage the lifecycle of Docker containers. Because
the Docker provider uses the Docker API, it is immediatel compatible not
only with single server Docker but Swarm and any additional Docker-compatible
API hosts.

Use the navigation to the left to read about the available resources.

## Example Usage

```
# Configure the Docker provider
provider "docker" {
    host = "tcp://127.0.0.1:1234/"
}

# Create a container
resource "docker_container" "foo" {
    image = "${docker_image.ubuntu.latest}"
    name = "foo"
}

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

## Argument Reference

The following arguments are supported:

* `host` - (Required) This is the address to the Docker host. If this is
  blank, the `DOCKER_HOST` environment variable will also be read.

* `cert_path` - (Optional) Path to a directory with certificate information
  for connecting to the Docker host via TLS. If this is blank, the
  `DOCKER_CERT_PATH` will also be checked.
