Kubernetes pods: a single instance of the application that encapsulates containers

• to bring up more instances of an application, the number of pods must be increased
• the smallest unit in Kubernetes

A single pod can have multiple containers of different types. It can include helper containers.

• within the same pod, they can interact with each other with the local network and share the same storage space
• when the pod dies, all the containers inside it die

kubectl run [name] --image [image name]: initiates single pod of an image

kubectl get pods: get the information of pods

• -o wide option shows where the node is running

kubectl describe pod [name of pod]: explains in detail about a single pod
