- add liveness check/fix readiness check - ensure 'redis-cli ping' actually returns 'PONG', as exit code is 0 even if errors will detect situations where redis is not available, such as due to to max clients being reached - bump redis memory/cpu for now (until autoscaling/automatic adjustment is available)
