DockerInfo - Comand /usr/bin/docker info

This parser reads the output of /usr/bin/docker info.

The resulting data structure is avaible in the data member of the class and takes the form of a dictionary whose keys are the “keys” in the output (the string before the :) and whose values are the values (the string following the :), all stripped of leading and trailing spaces.

Examples

>>> docker_info = shared[DockerInfo]
>>> docker_info.data['Containers']
'0'
>>> docker_info.data['ID']
'QPOX:46K6:RZK5:GPBT:DEUD:QM6H:5LRE:R63D:42DI:4BH3:6ZOZ:5EUM'

If the command does not return the information (for example, the Docker daemon isn’t running, the data dictionary is empty.

Bases: CommandParser

Represents the output of the /usr/bin/docker info command.

The resulting output of the command is essentially key/value pairs.
