            ## Description


            The version command prints the current version number for all independently

            
            versioned Docker components. Use the [`--format`](#format) option to customize

            
            the output.


            The version command (`docker version`) outputs the version numbers of Docker

            
            components, while the `--version` flag (`docker --version`) outputs the version

            
            number of the Docker CLI you are using.


            ### Default output


            The default output renders all version information divided into two sections;

            
            the `Client` section contains information about the Docker CLI and client

            
            components, and the `Server` section contains information about the Docker

            
            Engine and components used by the Docker Engine, such as the containerd and runc

            
            OCI Runtimes.


            The information shown may differ depending on how you installed Docker and

            
            what components are in use. The following example shows the output on a macOS

            
            machine running Docker Desktop:


            ```console

            
            $ docker version

            ### Client and server versions


            Docker uses a client/server architecture, which allows you to use the Docker CLI

            
            on your local machine to control a Docker Engine running on a remote machine,

            
            which can be (for example) a machine running in the cloud or inside a virtual machine.


            The following example switches the Docker CLI to use a [context](context.md)

            
            named `remote-test-server`, which runs an older version of the Docker Engine

            
            on a Linux server:


            ```console

            
            $ docker context use remote-test-server

            
            remote-test-server


            $ docker version


            Client: Docker Engine - Community

            
             Version:           28.5.1

            
             API version:       1.51

            
             Go version:        go1.24.8

            
             Git commit:        e180ab8

              Version:          0.19.0

            
              GitCommit:        de40ad0

            
            ```


            ### API version and version negotiation


            The API version used by the client depends on the Docker Engine that the Docker

            
            CLI is connecting with. When connecting with the Docker Engine, the Docker CLI

            
            and Docker Engine perform API version negotiation, and select the highest API

            
            version that is supported by both the Docker CLI and the Docker Engine.


            For example, if the CLI is connecting with Docker Engine version 27.5, it downgrades

            
            to API version 1.47 (refer to the [API version matrix](https://docs.docker.com/reference/api/engine/#api-version-matrix)

            
            to learn about the supported API versions for Docker Engine):


            ```console

            
            $ docker version --format '{{.Client.APIVersion}}'


            1.47

            
            ```


            Be aware that API version can also be overridden using the `DOCKER_API_VERSION`

            
            environment variable, which can be useful for debugging purposes, and disables

            
            API version negotiation. The following example illustrates an environment where

            
            the `DOCKER_API_VERSION` environment variable is set. Unsetting the environment

            
            variable removes the override, and re-enables API version negotiation:


            ```console

            
            $ env | grep DOCKER_API_VERSION

            
            DOCKER_API_VERSION=1.50


            $ docker version --format '{{.Client.APIVersion}}'

            
            1.50


            $ unset DOCKER_API_VERSION

            
            $ docker version --format '{{.Client.APIVersion}}'

            
            1.51

            
            ```


            ## Examples


            ### <a name="format"></a> Format the output (--format)


            The formatting option (`--format`) pretty-prints the output using a Go template,

            
            which allows you to customize the output format, or to obtain specific information

            
            from the output. Refer to the [format command and log output](https://docs.docker.com/config/formatting/)

            
            page for details of the format.


            ### Get the server version


            ```console

            
            $ docker version --format '{{.Server.Version}}'


            28.5.1

            
            ```


            ### Get the client API version


            The following example prints the API version that is used by the client:


            ```console

            
            $ docker version --format '{{.Client.APIVersion}}'


            1.51

            
            ```


            The version shown is the API version that is negotiated between the client

            
            and the Docker Engine. Refer to [API version and version negotiation](#api-version-and-version-negotiation)

            
            above for more information.


            ### Dump raw JSON data


            ```console

            
            $ docker version --format '{{json .}}'


            {"Client":"Version":"28.5.1","ApiVersion":"1.51", ...}

	## Description

	The version command prints the current version number for all independently
	versioned Docker components. Use the [`--format`](#format) option to customize
	the output.

	The version command (`docker version`) outputs the version numbers of Docker
	components, while the `--version` flag (`docker --version`) outputs the version
	number of the Docker CLI you are using.

	### Default output

	The default output renders all version information divided into two sections;
	the `Client` section contains information about the Docker CLI and client
	components, and the `Server` section contains information about the Docker
	Engine and components used by the Docker Engine, such as the containerd and runc
	OCI Runtimes.

	The information shown may differ depending on how you installed Docker and
	what components are in use. The following example shows the output on a macOS
	machine running Docker Desktop:

	```console
	$ docker version

	The following example prints the API version that is used by the client:

	```console
