*my python learning by doing something useful project

(the basic concept here is joining the node data with the pod data (podnode object = {'pod': object, 'node': object}) and then searching / formatting output of the joined columns)

(venv) ➜  kk git:(master) ✗ kubectl pn -h
kubectl (podnode|pn) [options]

Options:
    -h --help    show this
    -l STRING    label selector
    -f STRING    field selector
    -e STRING    exclude
    -o output    pydash format plus padding info, ie. node.metadata.name:62
    --offline    do not fetch new data, work on the last fetched data
    --json       print the -o elements in json format
    -w           watch mode

Example:
#    kubectl podnode \
#    -l 'app=streamtech-ibms-service/streamtech-cdn-selection-service' \
#    -f 'metadata.namespace=streamtech/content/commerce' \
#    -e 'metadata.owner_references[0].kind=DaemonSet' \
#    -o 'pod_name:62,node.metadata.labels.lifecycle,namespace,node.metadata.name:62' \
#    -w 

kubectl podnode -f 'metadata.namespace=streamtech/content/commerce'  \
   -e 'metadata.owner_references[0].kind=DaemonSet'   \
   -o 'pod_name:62,node.metadata.labels.lifecycle,namespace,node.metadata.name:62' \
   -w

kubectl podnode  \
    -l 'app=streamtech-ibms-service'   \
    -f 'metadata.namespace=streamtech/content/commerce'   \
    -e 'metadata.owner_references[0].kind=DaemonSet'   \
    -o 'pod_name:62,node.metadata.labels.lifecycle,namespace,node.metadata.name:62'  \
    -w

kubectl podnode  -e 'status.phase=Running/Succeeded'     -o 'pod_name:62,pod.status.phase,node.metadata.labels.lifecycle,namespace,node.metadata.name:15' -w
