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.

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.

• ca_material, cert_material, key_material, - (Optional) Content of ca.pem, cert.pem, and key.pem files for TLS authentication. Cannot be used together with cert_path.

~> NOTE on Certificates and docker-machine: As per Docker Remote API documentation, in any docker-machine environment, the Docker daemon uses an encrypted TCP socket (TLS) and requires cert_path for a successful connection. As an alternative, if using docker-machine, run eval $(docker-machine env <machine-name>) prior to running Terraform, and the host and certificate path will be extracted from the environment.
