Prerequisites:

Before we begin, ensure that you have the following installed on your local machine:
  • Kubernetes CLI (kubectl)
  • A running Kubernetes cluster
  • Access to the Kubernetes cluster with sufficient privileges to create and modify pods

Copy data to pod from local using kubectl command:

To copy data to a pod from your local machine using kubectl, follow the steps below:

Step 1: Identify the pod and the container you want to copy the data to.

kubectl get pods

This command will give you a list of all the pods running in the cluster.

Step 2: Once you have identified the pod and the container, create a directory on your local machine to store the files you want to copy to the pod.

mkdir /path/to/local/directory

Step 3: Copy the files to the directory you just created.

Step 4: Copy the files from your local machine to the pod using the kubectl cp command.

kubectl cp /path/to/local/directory <pod-name>:/path/to/destination

Replace <pod-name> with the name of the pod you want to copy the data to and /path/to/destination with the path to the directory where you want to copy the data in the pod.

Step 5: Verify that the files have been copied to the pod by logging into the pod and checking the contents of the directory where you copied the files.

kubectl exec -it <pod-name> -- /bin/bash
ls /path/to/destination
exit

Replace <pod-name> with the name of the pod you copied the data to.

More Examples:

Here are a few more examples of how to copy data to a pod from your local machine using kubectl:
  • Copy a single file to a pod:
kubectl cp /path/to/local/file.txt <pod-name>:/path/to/destination/file.txt
  • Copy all files in a directory to a pod:
kubectl cp /path/to/local/directory/. <pod-name>:/path/to/destination
  • Copy a file from a pod to your local machine:
kubectl cp <pod-name>:/path/to/file.txt /path/to/local/directory/file.txt

In this article, we explored how to copy data to a pod from a local machine using the kubectl command. With the help of the kubectl cp command, we can easily copy files and directories to and from pods in a Kubernetes cluster. We hope you found this article helpful.
