kpod: info subcommand Design: The output of the `info` subcommand ought to be directly consumable in a format like JSON or yaml. The structure being a map of sorts. Each subsection of information being an individual cluster under the top-level, like platform info, debug, storage, etc. Even if there are errors under the top level key, the value will be a map with the key of "error" and the value as the message of the `err.Error()`. In this way, the command always returns usable output. Ideally there will be a means for anything that can register info to do so independently from it being in the single info.go, so this approach is having a typed signature for the function that gives info, but i'm sure it could be better. Current iteration of this outputs the following as a limited user: ```yaml host: MemFree: 711307264 MemTotal: 2096222208 SwapFree: 2147479552 SwapTotal: 2147479552 arch: amd64 cpus: 1 os: linux store: error: 'mkdir /var/run/containers/storage: permission denied' ``` and as root (`sudo kpod info -D`): ```yaml debug: compiler: gc go version: go1.7.6 goroutines: 3 host: MemFree: 717795328 MemTotal: 2096222208 SwapFree: 2147479552 SwapTotal: 2147479552 arch: amd64 cpus: 1 os: linux store: ContainerStore: number: 1 GraphDriverName: overlay2 GraphRoot: /var/lib/containers/storage ImageStore: number: 1 ``` And with the `--json --debug` flag: ```json { "debug": { "compiler": "gc", "go version": "go1.7.6", "goroutines": 3 }, "host": { "MemFree": 709402624, "MemTotal": 2096222208, "SwapFree": 2147479552, "SwapTotal": 2147479552, "arch": "amd64", "cpus": 1, "os": "linux" }, "store": { "ContainerStore": { "number": 1 }, "GraphDriverName": "overlay2", "GraphRoot": "/var/lib/containers/storage", "ImageStore": { "number": 1 } } } ``` Signed-off-by: Vincent Batts <vbatts@hashbangbash.com>
