When an Ephemeral agent is started with an agent image for example : atlassian/bamboo-agent-base:9.6.2, it should be able to detect the capabilities automatically which are present inside the image.

---
apiVersion: v1
kind: Pod
metadata:
  name: '{{NAME}}'
  labels:
      '{{RESOURCE_LABEL}}': ephermeral
spec:
  containers:
    - image: atlassian/bamboo-agent-base:9.6.2
      name: '{{BAMBOO_AGENT_CONTAINER_NAME}}'
      env:
        - name: BAMBOO_EPHEMERAL_AGENT_DATA
          value: '{{BAMBOO_EPHEMERAL_AGENT_DATA_VAL}}'
  restartPolicy: Never

I should not be defining the capabilities manually, similar way it works for an agent which starts in docker using the same image where capabilities are automatically detected.
