version命令
Docker的version命令
介绍
https://docs.docker.com/engine/reference/commandline/version/
默认情况下，这将以易于阅读的布局呈现所有版本信息。 如果指定了格式，则将执行给定的模板。
使用
$ docker version
Client:
Version: 18.09.1
API version: 1.39
Go version: go1.10.6
Git commit: 4c52b90
Built: Wed Jan 9 19:35:23 2019
OS/Arch: linux/amd64
Experimental: false
Server: Docker Engine - Community
Engine:
Version: 18.09.1
API version: 1.39 (minimum version 1.12)
Go version: go1.10.6
Git commit: 4c52b90
Built: Wed Jan 9 19:02:44 2019
OS/Arch: linux/amd64
Experimental: false
格式化输出
$ docker version --format '{{json .}}'
则输出格式(https://www.json.cn/ 转格式)为：
{
"Client":{
"Platform":{
"Name":""
},
"Version":"18.09.1",
"ApiVersion":"1.39",
"DefaultAPIVersion":"1.39",
"GitCommit":"4c52b90",
"GoVersion":"go1.10.6",
"Os":"linux",
"Arch":"amd64",
"BuildTime":"Wed Jan 9 19:35:23 2019",
"Experimental":false
},
"Server":{
"Platform":{
"Name":"Docker Engine - Community"
},
"Components":[
{
"Name":"Engine",
"Version":"18.09.1",
"Details":{
"ApiVersion":"1.39",
"Arch":"amd64",
"BuildTime":"Wed Jan 9 19:02:44 2019",
"Experimental":"false",
"GitCommit":"4c52b90",
"GoVersion":"go1.10.6",
"KernelVersion":"4.15.0-38-generic",
"MinAPIVersion":"1.12",
"Os":"linux"
}
}
],
"Version":"18.09.1",
"ApiVersion":"1.39",
"MinAPIVersion":"1.12",
"GitCommit":"4c52b90",
"GoVersion":"go1.10.6",
"Os":"linux",
"Arch":"amd64",
"KernelVersion":"4.15.0-38-generic",
"BuildTime":"2019-01-09T19:02:44.000000000+00:00"
}
}
可以单独获取其中某个数据，如:
docker version --format '{{.Server.Version}}'
18.09.1
