码头工人机器检查
Usage: docker-machine inspect [OPTIONS] [arg...]
Inspect information about a machine
Description:
Argument is a machine name.
Options:
--format, -f Format the output using the given go template.
默认情况下,这会将有关计算机的信息呈现为JSON。如果指定了格式,则为每个结果执行给定的模板。
Go的文本/模板包描述了格式的所有细节。
除了text/template
语法外,还有一些其他函数
json
和prettyjson
,可用于将输出格式化为JSON(如下所述)。
例子
列出机器的所有详细信息:
这是的默认用法inspect
。
$ docker-machine inspect dev
{
"DriverName": "virtualbox",
"Driver": {
"MachineName": "docker-host-128be8d287b2028316c0ad5714b90bcfc11f998056f2f790f7c1f43f3d1e6eda",
"SSHPort": 55834,
"Memory": 1024,
"DiskSize": 20000,
"Boot2DockerURL": "",
"IPAddress": "192.168.5.99"
},
...
}
获取机器的IP地址:
在大多数情况下,您可以以一种非常直接的方式从JSON中选择任何字段。
$ docker-machine inspect --format='{{.Driver.IPAddress}}' dev
192.168.5.99
格式详细信息:
如果您希望将一部分信息格式化为JSON,则可以json
在模板中使用该函数。
$ docker-machine inspect --format='' dev-fusion
{"Boot2DockerURL":"","CPUS":8,"CPUs":8,"CaCertPath":"/Users/hairyhenderson/.docker/machine/certs/ca.pem","DiskSize":20000,"IPAddress":"172.16.62.129","ISO":"/Users/hairyhenderson/.docker/machine/machines/dev-fusion/boot2docker-1.5.0-GH747.iso","MachineName":"dev-fusion","Memory":1024,"PrivateKeyPath":"/Users/hairyhenderson/.docker/machine/certs/ca-key.pem","SSHPort":22,"SSHUser":"docker","SwarmDiscovery":"","SwarmHost":"tcp://0.0.0.0:3376","SwarmMaster":false}
虽然这是可用的,但不是很容易理解。因此,有
prettyjson
:
$ docker-machine inspect --format='{{prettyjson .Driver}}' dev-fusion
{
"Boot2DockerURL": "",
"CPUS": 8,
"CPUs": 8,
"CaCertPath": "/Users/hairyhenderson/.docker/machine/certs/ca.pem",
"DiskSize": 20000,
"IPAddress": "172.16.62.129",
"ISO": "/Users/hairyhenderson/.docker/machine/machines/dev-fusion/boot2docker-1.5.0-GH747.iso",
"MachineName": "dev-fusion",
"Memory": 1024,
"PrivateKeyPath": "/Users/hairyhenderson/.docker/machine/certs/ca-key.pem",
"SSHPort": 22,
"SSHUser": "docker",
"SwarmDiscovery": "",
