Running filters for 'crane status'

[saidimu]

I propose a flag to crane status which filters the output by a container's running status.

By default all containers defined in crane.yml are displayed, with the last column showing the runing status:

NAME  IMAGE  ID  UPTODATE  IP  PORTS  RUNNING

When one has a lot of non-running containers, a common-case with data-only containers, the output is mostly blank noise:

searchdata    busybox  -  -  -  -  -
postgresdata  busybox  -  -  -  -  -
queuedata     busybox  -  -  -  -  -

Perhaps such a flag already exists? Couldn't find anything in the v1.2.0 docs.

Given that the outputs of crane status -v and crane status are identical, a new flag isn't strictly needed as the current crane status output can be seen as the verbose option. The disadvantage of this is that it breaks existing behavior.

I can confirm that no such flag exists as of v1.2.0. I kind of like the idea, but I am not sure everyone would agree on what could be filtered out by default: non-running containers or non-existing containers?

I agree with @bjaglin, the filters would have to be explicit. -v is supposed to give more background information, not to alter the actual output/action.

I would be open to filters for the status command, but they have very low priority for me. If you would like to see them in Crane, please contribute them.
