[bitnami/milvus] 9.0.12 VPA semantic version mismatch for Milvus query nodes

[DarthBubi]

Name and Version

bitnami/milvus 9.0.12

What architecture are you using?

amd64

What steps will reproduce the bug?

1. AKS version 1.29.9, VPA managed by AKS
2. w/ VPA enabled for Query Node
3. Install via Terraform Helm provider or Helm directly
4. Semantic version mismatch error. See log output.

Are you using any custom parameters or values?

values.yaml:

...
queryNode:
  tolerations: 
    - key: "workload"
      operator: "Equal"
      value: "milvus"
      effect: "NoSchedule"
  affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
        - matchExpressions:
          - key: "kubernetes.azure.com/agentpool"
            operator: "In"
            values:
            - "milvuspool"
  resources:
    limits:
      cpu: "7"
      memory: "12Gi"
    requests:
      cpu: "3500m"
      memory: "4Gi"
  autoscaling:
    hpa:
      enabled: true
      targetCPU: "80"
    vpa:
      enabled: true
      minAllowed:
        cpu: "1"
        memory: "2Gi"
      maxAllowed:
        cpu: "7"
        memory: "12Gi"
...

set commands in Terraform:

...
set {
    name = "queryNode.replicas"
    value = var.milvus_queryNode_replicas
  }

  set {
    name = "queryNode.autoscaling.hpa.minReplicas"
    type = "string"
    value = var.milvus_queryNode_minReplicas
  }

  set {
    name = "queryNode.autoscaling.hpa.maxReplicas"
    type = "string"
    value = var.milvus_queryNode_maxReplicas
  }
...

What is the expected behavior?

No response

What do you see instead?

Semver mismatch: Error: template: milvus/templates/query-node/vpa.yaml:7:15: executing "milvus/templates/query-node/vpa.yaml" at <include "common.capabilities.vpa.apiVersion" .>: error calling include: template: milvus/charts/common/templates/_capabilities.tpl:160:39: executing "common.capabilities.vpa.apiVersion" at <semverCompare "<1.23-0" $kubeVersion>: error calling semverCompare: Invalid Semantic Version

Hi,

It seems that something is incorrect with the Capabilities.Kubeversion helm object. Could you try setting the value kubeVersion to 1.29.9 and see if that works?

[DarthBubi]

Yields the same error. Tried setting via Helm provider and values file.

When using Terraform, I don't think .Capabilities.Kubeversion helm object is properly populated, hence you need to manually specify the k8s version via the kubeVersion parameter, see:

• https://github.com/bitnami/charts/blob/main/bitnami/milvus/values.yaml#L36

That said, it seems the versions we use in the common.capabilities.vpa.apiVersion aren't valid, see:

• https://github.com/bitnami/charts/blob/main/bitnami/milvus/templates/query-node/vpa.yaml#L7
• https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_capabilities.tpl#L155-L169
• https://github.com/kubernetes/autoscaler/blob/master/vertical-pod-autoscaler/README.md#notice-on-deprecation-of-v1beta2-version-0130

Let me review this with the team.
