     9  # Docker Provider
    10  
    11  The Docker provider is used to interact with Docker containers and images.
    12  It uses the Docker API to manage the lifecycle of Docker containers. Because
    13  the Docker provider uses the Docker API, it is immediately compatible not
    14  only with single server Docker but Swarm and any additional Docker-compatible
    15  API hosts.
    16  
    17  Use the navigation to the left to read about the available resources.
    18  
    19  ## Example Usage
    20  
    21  ```hcl
    22  # Configure the Docker provider
    23  provider "docker" {
    24    host = "tcp://127.0.0.1:2376/"
    25  }
    26  
    27  # Create a container
    28  resource "docker_container" "foo" {
    29    image = "${docker_image.ubuntu.latest}"
    30    name  = "foo"
    31  }
    32  
    33  resource "docker_image" "ubuntu" {
    34    name = "ubuntu:latest"
    35  }
    36  ```
    37  
    38  ## Registry Credentials
    39  
    40  The initial (current) version of the Docker provider **doesn't** support registry authentication.
    41  This limits any use cases to public images for now.
    42  
    43  ## Argument Reference
    44  
    45  The following arguments are supported:
    46  
    47  * `host` - (Required) This is the address to the Docker host. If this is
    48    blank, the `DOCKER_HOST` environment variable will also be read.
    49  
    50  * `cert_path` - (Optional) Path to a directory with certificate information
    51    for connecting to the Docker host via TLS. If this is blank, the
    52    `DOCKER_CERT_PATH` will also be checked.
    53  
    54  * `ca_material`, `cert_material`, `key_material`, - (Optional) Content of `ca.pem`, `cert.pem`, and `key.pem` files
    55    for TLS authentication. Cannot be used together with `cert_path`.
    56  
    57  ~> **NOTE on Certificates and `docker-machine`:**  As per [Docker Remote API
    58  documentation](https://docs.docker.com/engine/reference/api/docker_remote_api/),
    59  in any docker-machine environment, the Docker daemon uses an encrypted TCP
    60  socket (TLS) and requires `cert_path` for a successful connection. As an alternative,
    61  if using `docker-machine`, run `eval $(docker-machine env <machine-name>)` prior
    62  to running Terraform, and the host and certificate path will be extracted from
    63  the environment.
