How to copy files from kubernetes Pods to local system

Solution 1:

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.

Consider advice of kchugalinskiy here #58692.

Solution 2:

Let's say you are copying file from bin folder to local system. The command is

kubectl cp default/POD_NAME:bin/FILE_NAME /Users/username/FILE_NAME

You can connect to POD to verify if you are specifying correct file name

kubectl exec -ti POD_NAME bash
