Service Mapping and Kubernetes - Patterns

[Sushil14]

Dear Experts,

I am new to Service Mapping and trying to learn more and know if the existing pattern of kubernetes cluster and other relative components discovery can be use for top-down (Service Mapping) discovery. We have some apps wherein the application services are dynamic and deployed monthly also infra CI are changing. on the top of it kubernetes cluster is also used. what I found in docs and some article that in such scenario we should use tag-based discovery and not traditional top down service mapping approach using patterns.

Can someone guide me with any ServiceNow link or related article that explain any similar scenario.

Thanks

To Start with First Run Simple Kubernetes Discovery -

(https://www.servicenow.com/community/itom-articles/kubernetes-components-discovery-using-service-now...)

Once K8 components are created then Run TAG Based Service Mapping- https://docs.servicenow.com/pt-BR/bundle/sandiego-it-service-management/page/product/service-mapping...

This is what service now also suggests .

Hi Sushil,

Please refer following documents for tags based discovery in service mapping.

thank you so much for these links it's helpful. I did test and i see the challenges are with relationship data. there are out of the box relations but lot of them i need to manually add to show the top-down map otherwise it seems a flat map.

Another question is on /cmdb_key_value_list table -- does this table automatically get populated whichever CI has tag coming from sources (integration or manually feed)? or we need to create tag- value manually in this table first.?

Please suggest

you dont need to add/create tags manually.

Make sure at source components have proper labels discovery will bring it and populate cmdb_key_value table.
