Usage: docker version [OPTIONS]
|
|

|
|

## Description
|
|
|
|
By default, this will render all version information in an easy to read
|
|
layout. If a format is specified, the given template will be executed instead.
|
|
|
|
Go's [text/template](https://golang.org/pkg/text/template/) package
|
|
describes all the details of the format.
|
|
|
|

### Get the server version
|
|
|
|
```console
|
|
$ docker version --format '{{.Server.Version}}'
|
|
|
|
19.03.8
|
|
```
|
|
|
|
### Dump raw JSON data
|
|
|
|
```console
|
|
$ docker version --format '{{json .}}'
|
|
|
|
{"Client":{"Platform":{"Name":"Docker Engine - Community"},"Version":"19.03.8","ApiVersion":"1.40","DefaultAPIVersion":"1.40","GitCommit":"afacb8b","GoVersion":"go1.12.17","Os":"darwin","Arch":"amd64","BuildTime":"Wed Mar 11 01:21:11 2020","Experimental":true},"Server":{"Platform":{"Name":"Docker Engine - Community"},"Components":[{"Name":"Engine","Version":"19.03.8","Details":{"ApiVersion":"1.40","Arch":"amd64","BuildTime":"Wed Mar 11 01:29:16 2020","Experimental":"true","GitCommit":"afacb8b","GoVersion":"go1.12.17","KernelVersion":"4.19.76-linuxkit","MinAPIVersion":"1.12","Os":"linux"}},{"Name":"containerd","Version":"v1.2.13","Details":{"GitCommit":"7ad184331fa3e55e52b890ea95e65ba581ae3429"}},{"Name":"runc","Version":"1.0.0-rc10","Details":{"GitCommit":"dc9208a3303feef5b3839f4323d9beb36df0a9dd"}},{"Name":"docker-init","Version":"0.18.0","Details":{"GitCommit":"fec3683"}}],"Version":"19.03.8","ApiVersion":"1.40","MinAPIVersion":"1.12","GitCommit":"afacb8b","GoVersion":"go1.12.17","Os":"linux","Arch":"amd64","KernelVersion":"4.19.76-linuxkit","Experimental":true,"BuildTime":"2020-03-11T01:29:16.000000000+00:00"}}

```
|
|
|
|
### Print the current context
|
|
|
|
The following example prints the currently used [`docker context`](context.md):
|
|
|
|
```console
|
|
$ docker version --format='{{.Client.Context}}'
|
|
default
|
|
```
|
|
|
|
As an example, this output can be used to dynamically change your shell prompt
|
|
to indicate your active context. The example below illustrates how this output
|
|
could be used when using Bash as your shell.
|
|
|
|
Declare a function to obtain the current context in your `~/.bashrc`, and set
|
|
this command as your `PROMPT_COMMAND`
|
|
|
|
```console
|
|
function docker_context_prompt() {
|
|
PS1="context: $(docker version --format='{{.Client.Context}}')> "
|
|
}
|
|
|
|
PROMPT_COMMAND=docker_context_prompt
|
|
```
|
|
|
|
After reloading the `~/.bashrc`, the prompt now shows the currently selected
|
|
`docker context`:
|
|
|
|
```console
|
|
$ source ~/.bashrc
|
|
context: default> docker context create --docker host=unix:///var/run/docker.sock my-context
|
|
my-context
|
|
Successfully created context "my-context"
|
|
context: default> docker context use my-context
|
|
my-context
|
|
Current context is now "my-context"
|
|
context: my-context> docker context use default
|
|
default
|
|
Current context is now "default"
|
|
context: default>
|
|
```
|
|
|
|
Refer to the [`docker context` section](context.md) in the command line reference
|
|
for more information about `docker context`.
