    Crashloopbakoff status- if your pod crashes in loop.
    Pod has container, container has application running as process.
    Deployment manifest applied.
    If pod, container and process are running, it will show status running. After a while maybe pod didn't get enough resources. Pod moves to crashed state, Kubernetes will again try to restart pod due to its default restart policy.
    Increase restart time in incremental way till span of 5 minute, delay is called backoff delay.
    Crashloopbackoff reason, miscommunication, wrong env variable, persistent volume that doesn't exist, liveness probe/redines probe fails, memory limits not enough, wrong command line arguments, bugs and exceptions in application code.

    - Day-2 : CrashLoopBackOff
    - This error seen when pods crash
    - Causes : Misconfiguration, Errors in the Liveness probe, Memory Limit too Low, Wrong command line argument, Bug & Exception on the application.
    - Solution
    - Misconfigure wrong command line argument on docker image could fall in CrashLoop, rebuild the image & re-apply deployment.
    - Errors on Liveness probe which is configured to health of application, reconfigure the probe accordingly.
    - OOM issue on the pod due to insufficient memory allocation or application memory leak, use thread dump to locate and identify the issue along with developer
    Resource Sharing
    - OOM Crash due to sharing resources across Kubernetes Clusters
    - Isolate Using Namespace
    - Allocate Resource Quota for Namespace as per requirement.
    - Requirement can be based on standard performance bench mark.
    - Pod level Isolation
    - To minimise the blast radius we can further isolate by setting Resource limits for Pods.
    - Each pod/ micro services can be allotted certain limits to prevent other pods getting crash on the same Namespace
    - Now, even after setting the above both and still pods get to Crash
    - Then, Create Thread dump kill -3 or try to get heap dump using Jstack -> Developer might need fix on the codes.
    - Upgrades Most common challenges
    - Even some DevOps might not seen OOM killed often or never seen, they can't miss to do Upgrades
    - To have smooth upgrades , below roadmaps were followed
    - Backup of Existing setup
    - Reading Release Notes
    - Isolate Task of Control plane such as Etcd, API, scheduler
    - and also isolate tasks on worker plane.
    - Drain the node -> UnSeclude -> Upgrade Kubelet -> Join back to Cluster
