kubectl exec

The kubectl exec command is used to execute a command inside a running container in a Kubernetes pod.

The syntax for the command is as follows:

kubectl exec [OPTIONS] POD_NAME COMMAND [ARG...]

where:

• POD_NAME is the name of the pod where the container is running.
• COMMAND is the command to be executed inside the container.
• [ARG...] are optional arguments to the command.

Some common options for kubectl exec are:

• -i specifies that the command should be executed interactively, allowing you to input data.
• -t attaches a terminal to the container, allowing you to interact with it.
• -c specifies the name of the container to execute the command in, if the pod has more than one container.

Example usage:

kubectl exec -it my-pod -- /bin/bash

This command will open a bash shell inside the container running in the my-pod pod
