|Anther ad-hoc way of moving data between pods is possible if you have 'netcat' tools installed in image for each application.|
Look at the example in:
The idea though is that on source pod you run:
tar zc *.txt | nc -l 60000
and on target pod you pull them using:
nc pod-name 60000 | tar zx
Replace 'pod-name' with actual pod name. The pod-name is mapped in internal DNS so you don't have to worry about what the IP address is.
