Hi,  
I got the error message for history and frontend pod:

Unable to start server: cassandra schema version compatibility check failed: version mismatch for keyspace/database: “temporal”. Expected version: 1.3 cannot be greater than Actual version: 0.0.

and got the error message for web pod:

standard\_init\_linux.go:219: exec user process caused: exec format error

anyone knows what is the problem?

above usually means the DB is not initialized (schema not initialized)  
you can reference this to setup the DB schema: [https://github.com/temporalio/temporal/blob/master/Makefile#L309](https://github.com/temporalio/temporal/blob/master/Makefile#L309)

cassandra seems to be up though:

default temporaltest-cassandra-0 1/1 Running 0 21h

The error `version mismatch for keyspace/database` suggest the DB schema is not applied to cassandra, not whether cassandra (as a deployment / service) is online or not.

somehow the check-cassandra init container of update pod can not talk to the cassandra pod

cqlsh temporaltest-cassandra.default.svc.cluster.local 9042  
Connection error: (‘Unable to connect to any servers’, {‘10.32.19.184’: error(None, “Tried connecting to [(‘10.32.19.184’, 9042)]. Last error: timed out”)})
