Challenges contributed by the community members sharing their knowledge and expertise.
Implement a canary deployment strategy using the Kubernetes Gateway API. Route the majority of traffic to a stable version of a service while gradually shifting a small percentage to a new canary version.
Create a PersistentVolumeClaim backed by a CSI StorageClass and run a storage performance benchmark using FIO inside a Kubernetes Job.
Configure a Kubernetes Gateway API setup to expose aviation platform services using path-based routing for flight and booking services.
Create an Ingress resource for a shop application with path-based routing to multiple backend services and configure /etc/hosts for local DNS resolution.
A Deployment with two nginx containers has a port conflict — both containers use port 80. Fix the conflict by updating the ConfigMap, mounting it into the second container, updating the containerPort, and exposing both containers via a NodePort Service.
A LimitRange exists in the namespace but Pods are not receiving default resource requests and limits. Investigate the root cause and fix it.
A Pod must be fully isolated from the cluster network. Deny all incoming traffic and block all outgoing traffic except DNS queries on port 53.
A developer named siddhi requires read-only access to specific resources in the production namespace. Create a Role and RoleBinding to grant the minimum required permissions without any write access.
Enforce Kubernetes security best practices by disabling automatic ServiceAccount token mounting and providing a short-lived projected token to the application Pod.
Create a StatefulSet and a Headless Service for a distributed caching system. Verify that Pods are created with stable ordinal names.
