Atomic unit of work in Kubernetes
They are the application/service
Can contain multiple containers
Pods cannot be created/destroyed, only instantiated
Pod lifecycle -> pending, ready, failed/succeeded
Pods are instantiated by Kubelet in the worker nodes
Pods can be scaled up/down
Pods have unique IPs
Containers within a Pod share namespace resources like network, mount, IPC, etc
Therefore containers within a Pod can share files and communicate with each other via localhost
Pods communicate with each other (with other pods) using the Pod network
There is a load balancer which routes traffic coming from outside to appropriate pod (with the help of kubeproxy)
