How to Copy Files from and to Kubernetes pods and Docker Container

At times we need to send files from kbernetes nodes to kubernets pods for different use cases. Lets see how to do that. You can either copy files or whole folders.

Copy Files from a pod to your machine

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

example:

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

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/
