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.

Note: 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://"

# 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.
