[CGX System]

What did you do to encounter the bug?
Steps to reproduce the behavior:

1. Install MongoDB in a kubernetes cluster using MongoDB Operator
2. Port-forward mongodb-svc on administrator PC
3. Connect and auth to MongoDB cluster in command line with mongosh

What did you expect?
A clean mongosh prompt

What happened instead?
Warning messages before entering the mongosh prompt :

------
   The server generated these startup warnings when booting
   2023-07-17T12:32:52.922+00:00: Using the XFS filesystem is strongly recommended with the WiredTiger storage engine. See http://dochub.mongodb.org/core/prodnotes-filesystem
   2023-07-17T12:32:55.659+00:00: /sys/kernel/mm/transparent_hugepage/enabled is 'always'. We suggest setting it to 'never'
   2023-07-17T12:32:55.659+00:00: vm.max_map_count is too low
------

Operator Information

• Operator Version : 0.8.0
• MongoDB Image used : docker.io/library/mongo

Kubernetes Cluster Information

Are the warnings important, and how can I get rid of them ?

@cgx-system try to set initContainer, should be something like this:

apiVersion: mongodbcommunity.mongodb.com/v1
kind: MongoDBCommunity
metadata:
  name: mongodb
spec:
  ...
  statefulSet:
    spec:
      template:
        spec:
          initContainers:
            - name: increase-vm-max-map
              image: busybox
              imagePullPolicy: IfNotPresent
              command: [ "sysctl", "-w", "vm.max_map_count=262144" ]
              securityContext:
                privileged: true
