Container: The CBContainers Images Fail to Deploy With Error "Not Supported By Windows"

Products

• Carbon Black Cloud Container

Issue/Introduction

Deploying the CBContainers components fails and the error can be seen "not supported by windows"

Environment

• VMware Carbon Black Container: All Supported Versions

Cause

This happens because the cbcontainers components don't support Kubernetes Windows nodes and can't successfully deploy to them

Resolution

• nodeAffinity can be setup on the components to avoid Windows nodes or only deploy to Linux nodes
• To avoid Windows nodes 

  affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
        - matchExpressions:
          - key: kubernetes.io/os
            operator: NotIn
            values:
            - windows

• To only deploy to Linux nodes

  affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
        - matchExpressions:
          - key: kubernetes.io/os
            operator: In
            values:
            - linux

Additional Information

Adding nodeAffinity by default is being looked into
