Editing CCU:Perstistent storage on the Kubernetes cluster (section)

=== Copying data from your local machine ===

From the local machine which has kubectl access to the cluster, you can directly copy data to and from the container using kubectl cp, which has a very similar syntax as scp:

<syntaxhighlight lang="yaml">
# to get data into the container, substitute name with correct id obtained from kubectl get pods
> kubectl cp /path/to/data/. pvc-access-pod:/my-pvc-mount/path/data
# to get data from the container
> kubectl cp pvc-access-pod:/my-pvc-mount/path/. /path/to/output/
</syntaxhighlight>

Read up on Kubernetes "kubectl cp" documentation to check how it handles directories, it's a bit unusual and slightly different from scp.

Note: kubectl cp internally uses tar and some compression to speed up network transfer. However, this means that your access pod needs a certain amount of memory,
in particular when transferring large files. If you run into "error 137" (out of memory), increase memory limits of the access pod or use scp from within the pod.
