Kubernetes is a open source tool that groups the containers into logical units to make up as application, which helps to manage the containers to achieve resource isolation, resource utilization, loosely/tightly coupled distributed workloads, distributions portability, CI & CD, high availability, scalability in lesser than few seconds Features Self-healing: without user intervention restarts the pods which is failed Networking: Pods can communicate within the node or outside the node also, each node/pod will have ip address Load balancing: Applications can be auto

Block until one or more containers stop, then print their exit codes

The docker update command dynamically updates container configuration. You can use this command to prevent containers from consuming too many resources from their Docker host.

Fast to create unlike VMsSince OS is not contained its light weightcontainer also contains the required versions of other applications needed for the appAny number of containers can be created quickly. The portability and performance benefits offered by containers can help you make your development process more agile and responsive

Containers virtualize the operating system unlike VMs, Containers are portable with that it means it can do development and deployment .In terms of docker its also runnable instance of image. we can have all dependency of an software into the image .  containers virtualize the OS, splitting it into virtualized compartments to run container applications.
