Viya 4 pod dependencies

woo — Thu, 19 Aug 2021 15:56:35 GMT

Hello,

We are trying to deploy Viya 4 on AWS environment (4 AWS instances - smp). After sort of deployment completes, few pods are nor coming up for all different reasons. However, one thing i was trying to understand is pod dependencies. I tried to look at different documents but didn't find much details. Do we have any documentatopn which shows pod dependencies or related information by any chance? Thank you.

Generally speaking, the stateless pods depend on the stateful pods and SAS Logon. So everything depends on consul and the database (which could be pods if internal is used). SAS Logon depends on cachelocator/cacheserver, and most everything else depends on SAS Logon.

$ kubectl -n viya get po -l workload.sas.com/class=stateful

This is correct and to add more in this if you really interested to see the SAS Logon POD details which is responsible for running all the services. This can be useful commands:

$ kubectl -n viya get pod

$ kubectl -n viya get pods | grep sas-logon | cut -f1 -d' '

You can configure lens with your cluster to see the in-depth details about the pods and it's performance. It gives you entire overview of the Storage, configuration, pods and their associations.
