# 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 immediately 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.
|
|
|
|

|
|
<strong>Note:</strong> The Docker provider is new as of Terraform 0.4.
|
|
It is ready to be used but many features are still being added. If there
|
|
is a Docker feature missing, please report it in the GitHub repo.
|
|

|

|
|
## Example Usage
|
|
|
|
```
|
|
# Configure the Docker provider
|
|
provider "docker" {
|
|
host = "tcp://127.0.0.1:2376/"
|
|
}
|
|
|
|
# Create a container
|
|
resource "docker_container" "foo" {
|
|
image = "${docker_image.ubuntu.latest}"
|
|
name = "foo"
|
|
}
|
|
|
|
resource "docker_image" "ubuntu" {
|
|
name = "ubuntu:latest"
|
|
}
|
|
```
|
|
|
|
## Registry Credentials
|
|
|
|
The initial (current) version of the Docker provider **doesn't** support registry authentication.
|
|
This limits any use cases to public images for now.
|
|
|
|
## 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.
|
|
|
|
Note: As per [Docker Remote API documentation](https://docs.docker.com/engine/reference/api/docker_remote_api/), in any docker-machine environment, the Docker daemon uses an encrypted TCP socket (TLS) and requires `cert_path` for a successful connection.
