Connection Refused Error Testing Golang API in Local Docker Environment

I'm trying to deploy a Go REST API to a local Docker container for testing. Deployment succeeds, but when I try to POST to the API, I receive the following error:

Error: connect ECONNREFUSED 127.0.0.1:8081

Here is my Dockerfile. I've already built the application locally and the binary is located at /web-admin-api:

FROM scratch

WORKDIR /web-admin-api

COPY . /web-admin-api

CMD ["/web-admin-api/application"]

EXPOSE 8081

And here's the Docker compose file:

version: "3.6"

services:
  app:
    container_name: web-admin-api
    hostname: web-admin-api
    restart: on-failure:3
    environment:
      GET_HOSTS_FROM: dns
        ports:
          - 8081:8081
        networks:
          - local

networks:
  local:
    driver: bridge

How can I get this set-up so that I can POST requests locally?

Try to post with host.docker.internal as the address instead of 127.0.0.1

You can read more about it at the documentation link 👉🏻 https://docs.docker.com/docker-for-mac/networking/#use-cases-and-workarounds
