SRE Public Tools - Kanivete

• Version: 0.1.1
• License: MIT
• Description: A swiss-army-knife debug container image to aid troubleshooting Kubernetes issues
• Reference: K8s doc

Contents

• Folder: build

Usage

Deploy a Target App

• You can deploy a standard nginx deployment for testing

kubectl apply -f usage/nginx-deployment.yaml

Ephemeral Debug Container (K8s v1.25)

• Debug a running container by attaching kanivete to it as an ephemeral container:

kubectl debug -it nginx-deployment-6ddcfb665f-hcj4c --image=rod4n4m1/kanivete:0.1.1 --target=nginx

• Re-attach the ephemeral container if needed (to be implemented):

kubectl attach nginx-deployment-6ddcfb665f-hcj4c -c debugger-rpk9w -i -t

Independent Pod

• Create a new pod based on the latest kanivete image:

kubectl run kanivete --image=rod4n4m1/kanivete:0.1.1 -- sleep 1d

• Open sh terminal on the kanivete container:

kubectl exec -it kanivete -- sh
