If breaking changes occur, they are documented prominently.\n\n> [!NOTE] > > The Docker daemon and client don't necessarily need to be the same version > at all times. However, keep the following in mind. > > - If the daemon is newer than the client, the client doesn't know about new > features or deprecated API endpoints in the daemon. > > - If the client is newer than the daemon, the client can request API > endpoints that the daemon doesn't know about.\n\nA new version of the API is released when new features are added. The Docker API is backward-compatible, so you don't need to update code that uses the API unless you need to take advantage of new features.\n\nTo see the highest and lowest version of the API your Docker daemon and client support, use docker version\n\nBounded code example (external data; do not execute automatically):\n```console\n$ docker version\nClient: Docker Engine - Community\n Version:           {{% param \"docker_ce_version\" %}}\n API version:       {{% param \"latest_engine_api_version\" %}}\n ...\n\nServer: Docker Engine - Community\n Engine:\n  Version:          {{% param \"docker_ce_version\" %}}\n  API version:      {{% param \"latest_engine_api_version\" %}} (minimum version 1.40)\n  ...\n```\n\nYou can specify the API version to use in any of the following ways\n\nWhen using the SDK, use the latest version. At a minimum, use the version that incorporates the API version with the features you need. When using curl directly, specify the version as the first part of the URL. For instance, if the endpoint is /containers/ you can use /v/containers/. To force the Docker CLI or the Docker Engine SDKs to use an older version of the API than the version reported by docker version, set the environment variable DOCKER_API_VERSION to the correct version. This works on Linux, Windows, and macOS clients.\n\n{{- $version := site.Params.latest_engine_api_version }} {{- $parts := strings.Split $version \".\" }} {{- $major := cast.ToInt (index $parts 0) }} {{- $minor := cast.ToInt (index $parts 1) }} …\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
