The package manager for Kubernetes

// Install packages in k8s

// Run this pod before of running every next commands.

kubectl run my-kafka-client --restart='Never' --image --namespace default --command -- sleep infinity

// run this in a terminal tab.
kubectl exec --tty -i my-kafka-client --namespace default -- bash --broker-list --topic test

// run these two commands in another terminal tab
kubectl exec --tty -i my-kafka-client --namespace default -- bash --bootstrap-server my-kafka.default.svc.cluster.local:9092 --topic test --from-beginning

// Useful Docker plugins

// Docker rootless mode

// Deploying Compose Docker files with Helm. Best of both worlds
