A Pod in Kubernetes is a group of containers that are deployed on the same host. They operate at a higher level than single containers. They run as a single unit and share the same content. They share the same IP address and can reach one another with the help of the localhost. They may also share the same storage space. They are not required to run on a single machine since containers have the capability of running in a number of machines. A single node can run multiple pods.
Pods might get terminated in cases of machine failure. For this reason, they are often referred to as “fleeting cattle”. They are managed by a Replication Controller for high resiliency. It helps in creating and destroying clones of pods as required.
To learn more about Pods and Kubernetes, you must register for an online Kubernetes Training.
