request_count_metrics_name: foo.alb.request_count
target_processing_time_metrics_name: foo.alb.target_processing_time
target_paths:
  - /api/v1/foo
  - /api/v1/bar
  - /api/v1/hoge
path_transforming_rules:
  - prefix: /api/v1/bar
    transformed: /api/v1/$id
  - prefix: /api/v1/hoge
    suffix: /start
    transformed: /api/v1/hoge/$id/start
  - regexp: /api/v1/hoge/[^/]+/stop
    transformed: /api/v1/hoge/$id/stop

Example Dockerfile :

FROM ghcr.io/reproio/send-alb-metrics-to-datadog:latest AS base

FROM public.ecr.aws/lambda/provided:al2
COPY --from=base /main /main
COPY config.yaml /config.yaml
ENTRYPOINT [ "/main" ]
