Copy Files from a pod to your machine

kubectl cp {{namespace}}/{{podname}}:path/to/directory /local/path

Copy Files to a pod

kubectl cp /local/path namespace/podname:path/to/directory

example:
[root@ip-10-0-1-4 centos]# kubectl cp gateway-service  scdf-server-75b598cc56-b64hs:/root/scdfflowproject/                   
[root@ip-10-0-1-4 centos]# kubectl cp second-service  scdf-server-75b598cc56-b64hs:/root/scdfflowproject/
