This repo houses various sets of problematic k8s resources, can you debug them?
Each "bug" lives in it's own subdirectory. The subdirectories are sorted into the following categories:
workload- Covering containers, pods, and all controller types in Kubernetesservices-networking- Covering services, discovery (DNS), network policies, and ingressconfig-storage- Covering configMaps, secrets, the downward API, and the elements of the persistent volume subsystemobservability- Covering workload scaling, metrics, logs, and eventscluster- Covering control plane components, kubelets, various plugins (Network, Storage and Container Runtimes)security- Covering Role-based access control, security contexts, ServiceAccounts, and various policies
The subdirectories contain the following files:
- README.md - explains the context of the problem the resources exhibit
- problem.yaml - the bug, apply this manifest to your cluster and see if you can debug it
- solution.md - an explanation of what is wrong, how to diagnose such a problem and how to fix it
Each problem is designed to be independent of one another and can be completed in any order.
Do not run these manifests on a cluster you care about!!
These problem resources can impact the functioning of you cluster and/or it's applications (they are problems after all!). All of the problems are designed to be compatible with recent versions of Kubernetes (1.18+).
