Question 86
You have a StatefulSet named 'mysql-cluster' running a MySQL database with 3 replicas. You want to add a new replica to the cluster without disrupting the existing database operations. How do you achieve this while ensuring data consistency and minimal downtime?
Question 87
You are setting up a persistent volume to host a MySQL database, but you want to ensure data consistency and availability. You have multiple nodes in your Kubernetes cluster. Describe the volume mode, access mode, and reclaim policy you would use for this volume.
Question 88
Create a Pod with main container busybox and which executes this
"while true; do echo 'Hi I am from Main container' >>
/var/log/index.html; sleep 5; done" and with sidecar container
with nginx image which exposes on port 80. Use emptyDir Volume
and mount this volume on path /var/log for busybox and on path
/usr/share/nginx/html for nginx container. Verify both containers
are running.

Name: super-secret
password: bob
Create a pod named pod-secrets-via-file, using the redis Image, which mounts a secret named super-secret at
/secrets.
Create a second pod named pod-secrets-via-env, using the redis Image, which exports password as CONFIDENTIAL
