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,这将将有关机器的信息呈现为JSON。如果指定了格式,则将对每个结果执行给定的模板。

文本/模板包描述格式的所有细节。

除了text/template语法之外,还有一些额外的功能,json并且prettyjson可以用来将输出格式化为JSON(如下文档所述)。

实例

列出机器的所有细节:

这是默认的使用方式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,您可以以相当简单的方式从JSON中选择任何字段。

$ docker-machine inspect --format='{{.Driver.IPAddress}}' dev192.168.5.99

格式化详细信息:

如果希望将信息子集格式化为JSON,则可以使用json函数在模板中。

$ 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,但它并不是很容易读懂。因此,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": "",  
    "SwarmHost": "tcp://0.0.0.0:3376",  
    "SwarmMaster": false
}
