How to copy files from kubernetes Pods to local system

Question

I'm trying to copy files from Kubernetes Pods to my local system. I am getting the below error while running following command:

kubectl cp aks-ssh2-6cd4948f6f-fp9tl:/home/azureuser/test.cap ./test.cap 

Output:

tar: home/azureuser/test: Cannot stat: No such file or directory tar: Exiting with failure status due to previous errors error: home/azureuser/test no such file or directory

I could see the file under above given path. I am really confused.

Could you please help me out?

As stated inkubectl help:

kubectl cp --help Copy files and directories to and from containers. Examples: # !!!Important Note!!! # Requires that the 'tar' binary is present in your container # image.  If 'tar' is not present, 'kubectl cp' will fail.  # Copy /tmp/foo_dir local directory to /tmp/bar_dir in a remote pod in the default namespace kubectl cp /tmp/foo_dir <some-pod>:/tmp/bar_dir  # Copy /tmp/foo local file to /tmp/bar in a remote pod in a specific container kubectl cp /tmp/foo <some-pod>:/tmp/bar -c <specific-container>  # Copy /tmp/foo local file to /tmp/bar in a remote pod in namespace <some-namespace> kubectl cp /tmp/foo <some-namespace>/<some-pod>:/tmp/bar  # Copy /tmp/foo from a remote pod to /tmp/bar locally kubectl cp <some-namespace>/<some-pod>:/tmp/foo /tmp/bar  Options: -c, --container='': Container name. If omitted, the first container in the pod will be chosen  Usage: kubectl cp <file-spec-src> <file-spec-dest> [options]  Use "kubectl options" for a list of global command-line options (applies to all commands). 

You can also login to your Containter and check if file is there:

kubectl exec -it aks-ssh2-6cd4948f6f-fp9tl /bin/bash ls -la /home/azureuser/test.cap 

If this still doesn't work, try:

You may try to copy your files to workdir and then retry to copy them using just their names. It's weird, but it works for now.
