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-nautilus.
For the first container, use image ubuntu with latest tag only and remember to mention the tag i.e ubuntu:latest, container should be named as volume-container-nautilus-1, and run a sleep command for it so that it remains in running state. Volume volume-share should be mounted at path /tmp/official.
For the second container, use image ubuntu with the latest tag only and remember to mention the tag i.e ubuntu:latest, container should be named as volume-container-nautilus-2, and again run a sleep command for it so that it remains in running state. Volume volume-share should be mounted at path /tmp/demo.
Volume name should be volume-share of type emptyDir.
After creating the pod, exec into the first container i.e volume-container-nautilus-1, and just for testing create a file official.txt with any content under the mounted path of first container i.e /tmp/official.
The file official.txt should be present under the mounted path /tmp/games on the second container volume-container-nautilus-2 as well, since they are using a shared volume.
Note: The kubectl utility on jump_host has been configured to work with the kubernetes cluster.
