entrypoint.sh not working as expected

[alpha-er]

After release 12.6.5290, the entrypoint.sh script doesn't seem to work in terms of placing values in conf.d files bases on environment variables.

For example, 12.6.5290 dd-agent image places the KUBERNETES* env values into /etc/dd-agent/conf.d/kubernetes.yaml:

docker run --rm -it \
  -e 'KUBERNETES=yes' \
  -e 'KUBERNETES_COLLECT_EVENTS=yes' \
  -e 'KUBERNETES_NAMESPACE_NAME_REGEX=blue' \
  datadog/docker-dd-agent:12.6.5290 /bin/bash

root@0364e253be2d:/# cat /etc/dd-agent/conf.d/kubernetes.yaml | grep -v '#'
init_config:

instances:

 - port: 4194



   collect_events: true



   namespace_name_regexp: blue

While in the next release, 12.6.5300, it doesn't:

docker run --rm -it \
  -e 'KUBERNETES=yes' \
  -e 'KUBERNETES_COLLECT_EVENTS=yes' \
  -e 'KUBERNETES_NAMESPACE_NAME_REGEX=blue' \
  datadog/docker-dd-agent:12.6.5300 /bin/bash
