Memory locking requested for elasticsearch process but memory is not locked

Elastic Stack Elasticsearch
1

i am enabling bootstrap.memory_lock: true on kubrnetes deployment of elastic multi node cluster. getting below error.

Tried with this one

#Set memlock limit
      - name: memlock-limit
        image: busybox
        imagePullPolicy: IfNotPresent
        command: ["sh", "-c", "ulimit -l unlimited"]
        securityContext:
          privileged: true
# Increase the max number of open file descriptors.
      - name: increase-fd-ulimit
        image: busybox
        imagePullPolicy: IfNotPresent
        command: ["sh", "-c", "ulimit -n 65536"]
        securityContext:
          privileged: true


Then tried doing it with adding in limits.conf file
elasticsearch soft memlock unlimited

elasticsearch hard memlock unlimited

still getting below error on logs

I am not able to access the /usr/share/Elasticsearch/logs/Elasticsearch.log as container gets killed
