Kubernetes for the Impatient
Pods, deployments, services, ingress, helm - the minimum you need to run something real.
“Kubernetes doesn't make your app more resilient. It makes your app more complicated and then gives you the tools to deal with that complication.”
What you'll learn
Pods & deploymentsServicesIngressHelmConfigMaps & secrets
A Pod is the smallest deployable unit (one or more containers). A Deployment manages Pods (replicas, rolling updates, rollbacks). Always use Deployments, never bare Pods.
Services expose Pods internally (ClusterIP) or externally (LoadBalancer/NodePort). Ingress routes external HTTP/S traffic to Services based on hostname or path. Always use Ingress for production traffic.
