Terraform Provider for Docker

Sponsored by Coder

What You Can Manage With This Provider

This provider covers more than basic Docker images and containers. With Terraform, you can manage:

Compose applications with docker_compose
Image builds and registry workflows with docker_image, docker_registry_image, and docker_tag
Buildx builders for advanced multi-platform builds with docker_buildx_builder
Swarm services with docker_service
Runtime resources such as docker_container, docker_network, and docker_volume
Supporting platform objects like docker_config, docker_secret, and docker_plugin
Operational actions such as docker_exec, docker_image_import, docker_image_load, docker_image_save, docker_container_export and docker_system_prune,

Available data sources include images, image tags and manifests, containers, networks, plugins, and container logs. See the full provider documentation for the complete resource and data source list.

Documentation

The documentation for the provider is available on the Terraform Registry.
You need at least Terraform 1.1.5 to use this provider.

Migration guides:
Do you want to migrate from v3.x to v4.x? Please read the V3 - V4 migration guide

• Do you want to migrate from v2.x to v3.x? Please read the V2 - V3 migration guide

Example usage

Take a look at the examples in the documentation of the registry
or use the following example:

# Set the required provider and versions
terraform {
  required_providers {
    # We recommend pinning to the specific version of the Docker Provider you're using
    # since new versions are released frequently
    docker = {
      source  = "kreuzwerker/docker"
      # or if you want to pull from opentfu
      source = "registry.opentofu.org/kreuzwerker/docker"
      version = "4.5.0"
    }
  }
}
Configure the docker provider

provider "docker" {
}
Create a docker image resource

-> docker pull nginx:latest

resource "docker_image" "nginx" {
  name         = "nginx:latest"
  keep_locally = true
}
Create a docker container resource

-> same as 'docker run --name nginx -p8080:80 -d nginx:latest'

resource "docker_container" "nginx" {
  name    = "nginx"
  image   = docker_image.nginx.image_id
  ports {
    external = 8080
    internal = 80
  }
}
Or create a service resource

-> same as 'docker service create -d -p 8081:80 --name nginx-service --replicas 2 nginx:latest'

resource "docker_service" "nginx_service" {
  name = "nginx-service"
  task_spec {
    container_spec {
      image = docker_image.nginx.repo_digest
    }
  }
  mode {
    replicated {
      replicas = 2
    }
  }
  endpoint_spec {
    ports {
      published_port = 8081
      target_port    = 80
    }
  }
}
