Kubernetes Runtime

This cookbook demonstrates how to use the Kubernetes runtime to interact with a Kubernetes pod.

Prerequisites

• A Kubernetes cluster
• Opsmate installed on your machine

Interact with a pre-existing Kubernetes pod

First let's create a pod in the Kubernetes cluster.

kubectl run -i --tty --rm debug --image=alpine -- sh

Now that we have a pod running, we can interact with it using Opsmate's Kubernetes runtime.

opsmate run -nt --runtime
k8s --runtime-k8s-pod debug "what's the distro of this container?" --tools ShellCommand
The container is running Alpine Linux, version 3.21.3.

Here are some of the common configuration options for the Kubernetes runtime:

  --runtime-k8s-shell TEXT        Set shell_cmd (env: RUNTIME_K8S_SHELL)
  --runtime-k8s-container TEXT    Name of the container of the pod, if not
  --runtime-k8s-pod TEXT          Set pod_name (env: RUNTIME_K8S_POD)
  --runtime-k8s-namespace TEXT    Set namespace (env: RUNTIME_K8S_NAMESPACE)
