How to copy the files/directories into Kubernetes (K8S) Pods from local to remote pods (either ways)

Sometimes, we may get into situations where we need files from Kubernetes (K8S) pods to local file system & vice versa.

K8S has built-in commands for copying resources into & from K8S pods.

Case 1: To copy into local system from remote pods

kubectl cp <namespace_of_pod>/<pod_generated_name>:<source_copying_dir_path> <destination_local_dir_path>

kubectl cp catalog /catalog-app-es1xy2323sds:/appl/repositories     ~/

(here, I am copying the directory /appl/repositories from remote pod named catalog-app-es1xy2323sds (generated name) from Kubernetes cluster to local root path ~/ 

Case 2: To copy from local system to remote pods

kubectl cp <source_local_dir_path> <namespace_of_pod>/<pod_generated_name>:<destination_copying_dir_path> 

kubectl cp  ~/config  catalog /catalog-app-es1xy2323sds:/appl/repositories 

(here, I am copying the directory ~/config from local file system to remote pod named catalog-app-es1xy2323sds (generated name) in the namespace catalog)

you can search for all the namespaces using

kubectl get namespaces

you can search all the pods for a particular namespace using

kubectl get pods -n <namespace_name>
