Mongo DB deployment not working in kubernetes because processor doesn't have AVX support

Question

I am trying to deploy a mongo db deployment together with service, as follows:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mongo-deployment
  labels:
    app: mongo
spec:
  replicas: 1
  selector:
    matchLabels:
      app: mongo
  template:
    metadata:
      labels:
        app: mongo
    spec:
      containers:
      - name: mongo
        image: mongo:5.0
        ports:
        - containerPort: 27017
        env:
        - name: MONGO_INITDB_ROOT_USERNAME
          valueFrom:
            secretKeyRef: 
              name: mongo-secret
              key: mongo-user
        - name: MONGO_INITDB_ROOT_PASSWORD
          valueFrom:
            secretKeyRef: 
              name: mongo-secret
              key: mongo-password
---
apiVersion: v1
kind: Service
metadata:
  name: mongo-service
spec:
  selector:
    app: mongo
  ports:
    - protocol: TCP
      port: 27017
      targetPort: 27017

Even though everything seems to be configured right and deployed, it gets to a CrashLoopBackOff state instead of Running, using a kubectl logs <deployment-name> I get the following error:

MongoDB 5.0+ requires a CPU with AVX support, and your current system does not appear to have that!

Does anybody know what to do?

Answer 1

To solve this issue I had to run an older mongo-db docker image version (4.4.6), as follows:

image: mongo:4.4.6

Reference:

Mongo 5.0.0 crashes but 4.4.6 works #485

Answer 2

The latest version that can work WITHOUT AVX is

image: mongo:4.4.18

but if you are using it on a VPS, its worth a shot to contact their support, mine said that they changed the CPU type and that fixed the problem.
