Core Kubernetes Objects

There are a number of core Kubernetes objects that you need to know about to understand how your containerised apps get deployed into a Kubernetes cluster:

Deployments & ReplicaSets are the most common way to deploy a horizontally-scaled app into a cluster
Services & Ingresses - expose your app within or outside of the cluster so other apps and services can connect to them
Namespaces act as “virtual clusters” within your cluster and are useful for segregating your workloads
ConfigMaps & Secrets store configuration data for your pods and pass it into your running app in a secure fashion
