  This document provides an overview of Docker features, products, and
  open-source projects that have been deprecated, retired, or transitioned.
  Note
  This page does not cover deprecated and removed Docker Engine features.
  For a detailed list of deprecated Docker Engine features, refer to the
  Docker Engine Deprecated Features documentation
  Products and features
  Support for these deprecated or retired features is no longer provided by
  Docker, Inc. The projects that have been transitioned to third parties continue
  to receive updates from their new maintainers.
  Docker Machine
  Docker Machine was a tool for provisioning and managing Docker hosts across
  various platforms, including virtual machines and cloud providers. It is no
  longer maintained, and users are encouraged to use
  Docker Desktop
  Docker Engine
  directly on supported platforms.
  Machine's approach to creating and configuring hosts has been superseded by
  more modern workflows that integrate more closely with Docker Desktop.
  Docker Toolbox
  Docker Toolbox was used on older systems where Docker Desktop could not run. It
  bundled Docker Machine, Docker Engine, and Docker Compose into a single
  installer. Toolbox is no longer maintained and is effectively replaced by
  Docker Desktop
  on current systems. References to
  Docker Toolbox occasionally appear in older documentation or community
  tutorials, but it is not recommended for new installations.
  Docker Cloud integrations
  Docker previously offered integrations for Amazon's Elastic Container Service
  (ECS) and Azure Container Instances (ACI) to streamline container workflows.
  These integrations have been deprecated, and users should now rely on native
  cloud tools or third-party solutions to manage their workloads. The move toward
  platform-specific or universal orchestration tools reduced the need for
  specialized Docker Cloud integrations.
  You can still view the relevant documentation for these integrations in the
  Compose CLI repository
  Docker Enterprise Edition
  Docker Enterprise Edition (EE) was Docker's commercial platform for deploying
  and managing large-scale container environments. It was acquired by Mirantis in
  2019, and users looking for enterprise-level functionality can now explore
  Mirantis Kubernetes Engine or other products offered by Mirantis. Much of the
  technology and features found in Docker EE have been absorbed into the Mirantis
  product line.
  Note
  For information about enterprise-level features offered by Docker today,

  Docker Business subscription
  Docker Data Center and Docker Trusted Registry
  Docker Data Center (DDC) was an umbrella term that encompassed Docker Universal
  Control Plane (UCP) and Docker Trusted Registry (DTR). These components
  provided a full-stack solution for managing containers, security, and registry
  services in enterprise environments. They are now under the Mirantis portfolio
  following the Docker Enterprise acquisition. Users still encountering
  references to DDC, UCP, or DTR should refer to Mirantis's documentation for
  guidance on modern equivalents.
  Dev Environments
  Dev Environments was a feature introduced in Docker Desktop that allowed
  developers to spin up development environments quickly. It was deprecated and removed from Docker Desktop version 4.42 and later. Similar workflows can be achieved through
  Docker Compose or by creating custom configurations tailored to specific
  project requirements.
  Open source projects
  Several open-source projects originally maintained by Docker have been
  archived, discontinued, or transitioned to other maintainers or organizations.
  Registry (now CNCF Distribution)
  The Docker Registry served as the open-source implementation of a container
  image registry. It was donated to the Cloud Native Computing Foundation (CNCF)
  in 2019 and is maintained under the name "Distribution." It remains a
  cornerstone for managing and distributing container images.
  CNCF Distribution
  Docker Compose v1 (replaced by Compose v2)
  Docker Compose v1 (
  docker-compose
  ), a Python-based tool for defining
  multi-container applications, has been superseded by Compose v2 (
  docker compose
  ), which is written in Go and integrates with the Docker CLI. Compose
  v1 is no longer maintained, and users should migrate to Compose v2.
  Compose v2 Documentation
  InfraKit
  InfraKit was an open-source toolkit designed to manage declarative
  infrastructure and automate container deployments. It has been archived, and
  users are encouraged to explore tools such as Terraform for infrastructure
  provisioning and orchestration.

  Docker Notary (now CNCF Notary)
  Docker Notary was a system for signing and verifying the authenticity of
  container content. It was donated to the CNCF in 2017 and continues to be
  developed as "Notary." Users seeking secure content verification should consult
  the CNCF Notary project.
  CNCF Notary
  SwarmKit
  SwarmKit powers Docker Swarm mode by providing orchestration for container
  deployments. While Swarm mode remains functional, development has slowed in
  favor of Kubernetes-based solutions. Individuals evaluating container
  orchestration options should investigate whether SwarmKit meets modern workload
  requirements.
