Aerospike user not found when running as nonroot

I am using community edition aerospike docker image. Our k8s cluster does not allow running containers as root. hence i started following this doc for running as non root.

But when run the image i am getting below error

link eth0 state up
link eth0 state up in 0
Dec 02 2021 10:15:12 GMT: CRITICAL (config): (cfg.c:2168) line 6 :: user not found: 8888
Dec 02 2021 10:15:12 GMT: WARNING (as): (signal.c:166) SIGINT received, shutting down Aerospike Community Edition build 5.6.0.7 os debian10
Dec 02 2021 10:15:12 GMT: WARNING (as): (signal.c:169) startup was not complete, exiting immediately

I am having below config in my aerospike conf

    service {
      user 8888
      group 8888
      paxos-single-replica-limit 1 # Number of nodes where the replica count is automatically reduced to 1.
      pidfile /var/run/aerospike/asd.pid
      # service-threads 6 # cpu x 5 in 4.7
      # transaction-queues 6 # obsolete in 4.7
      # transaction-threads-per-queue 4 # obsolete in 4.7
      proto-fd-max 15000
      }

and below is my k8s config

          securityContext:
            runAsUser: 8888

          resources:
            requests:
              memory: 1Gi

            limits:
              memory: 1Gi
              cpu: 1

I think this is not Kubernetes related but just aerospike You are using uid/gid

user 8888
group 8888

Could you try using username/groupname

service {
      user aerospike
      group aerospike
      paxos-single-replica-limit 1 # Number of nodes where the replica count is automatically reduced to 1.
      pidfile /var/run/aerospike/asd.pid
      # service-threads 6 # cpu x 5 in 4.7
      # transaction-queues 6 # obsolete in 4.7
      # transaction-threads-per-queue 4 # obsolete in 4.7
      proto-fd-max 15000
      }
