omg_all_logs

The openshift cli 'oc' allows you to interactively get logs from all containers within a pod.

$ oc logs pod/rook-ceph-osd-7-7ccdbcd4f4-nxfv5 --all-containers

omg lacks the --all-containers option, but 'omg_all_logs' extends omg to allow all containers. Updated to also capture the previous log if it exists.

Usage :

$ omg_all_logs
Usage: path/to/omg_all_logs -p _pattern_ -o _output_dir_
will get all container logs for pod matching _pattern_
Output is to stdout unless -o is specified

skips pods matching replicaset and deployment as omg is unable to extract those logs

Example with osd-7 and output to cephout directory

$ omg_all_logs -p osd-7 -o cephout

Will capture all oc logs for pods :
	pod/rook-ceph-osd-7-7ccdbcd4f4-nxfv5
Continue? any key or ctrl-c to quit
