I am trying to instrument a Java application orchestrated in an EKS cluster.
I've set DD_AGENT_HOST as guided in Kubernetes APM - Trace Collection docs with the following YAML.
env:
- name: DD_AGENT_HOST
valueFrom:
fieldRef:
fieldPath: status.hostIPThis was not a problem and worked well in a IPv4 EKS environment. However, the Agent fails when an IPv6 address is given:
