Terraform Provider for Docker

Sponsored by Coder

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 = "4.0.0"
    }
  }
}

# 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
    }
  }
}
