Kubernetes Shared Volumes

 Question : We are working on an application that will be deployed on multiple containers within a pod on Kubernetes cluster. There is a requirement to share a volume among the containers to save some temporary data. The Nautilus DevOps team is developing a similar template to replicate the scenario. Below you can find more details about it.

Create a pod named volume-share-datacenter.

For first container, use image centos with latest tag only and remember to mention tag i.e centos:latest, container should be named as volume-container-datacenter-1, and run a command '/bin/bash', '-c' and 'sleep 10000'. Volume volume-share should be mounted at path /tmp/news.

For second container, use image centos with latest tag only and remember to mention tag i.e centos:latest, container should be named as volume-container-datacenter-2, and run a command '/bin/bash', '-c' and 'sleep 10000'. Volume volume-share should be mounted at path /tmp/cluster.

Volumes to be named as volume-share and use emptyDir: { }.

After creating pods, exec into the first container volume-container-datacenter-1, and create a file news.txt with content Welcome to xFusionCorp Industries! under the mount path of first container i.e /tmp/news.

The file news.txt should be present under the mounted path /tmp/cluster of second container volume-container-datacenter-2 as they are using shared volumes.

Please Note :-  Perform the below commands based on your question  server,  user name & other details might differ . So please read task carefully before executing. All the Best 👍
