  # This service is used to make a sample request to tag-page-rendering only after it has started and is healthy.
  # It exits immediately after making the request, so it is not a long-running service.
  # View the logs via:
  #   docker logs "$(docker ps -aq --filter "name=sample-request" --latest)"
  # The log output is the DCR response, so we can also pipe it through `jq` to pretty-print it, e.g.:
  #   docker logs "$(docker ps -aq --filter "name=sample-request" --latest)" | jq .
