What is the procedure to perform kibana upgrade with zero downtime.
Welcome to our community! 
You will incur downtime as the container needs to restart and Kibana may need to run upgrade steps. There's no way around that.

is the process just docker-compose down and changing version tag and docker-compose up? or is
there any alternative ??
Yes that will work for Kibana.

Can we perform a rolling upgrade to the elasticsearch from 7.17 to 8.X without data loss? we don't have the space to take the snapshots.
Yes you can.
If i upgrade my Elastic Search Cluster from 7.17.9 to 8.6.2 by Rolling Upgrade, But kibana will be running on 7.17.6, Then am i able to check the cluster status,health and shards from kibana ?? or KIbana should also compatible with Elasticsearch, as i am following the procedure for upgrade like Disable shard Allocation and Re-enable shard Allocation, i am doing from Kibana, if my kibana is down with ES 8.6.2 node, then i cant run other steps and also if i have to check Shards, Nodes, my kibana should also have 8.6.2 version ???
Q2: As im having Imp data, is it possible to upgrade 7.17.9 to 8.6.2 using Rolling Upgrade ?
