golang程序在docker外部运行良好，但在dockerized时以0退出

I have the following docker-compose.yml file:

version: "3.3"

services:
  api:
    build: ./api
    expose:
      - '8080'
    container_name: 'api'
    ports:
      - "8080:8080"
    depends_on:
      - db
    stdin_open: true
    tty: true    
    networks:
      - api-net

  db:
    build: ./db
    expose:
      - '27017'
    container_name: 'mongo'
    ports:
      - "27017:27017"
    networks:
      - api-net

networks:
  api-net:
    driver: bridge

and the Dockerfile for the api container is as follows:

FROM iron/go:dev
RUN mkdir /app
COPY src/main/main.go /app/
ENV SRC_DIR=/app
ADD . $SRC_DIR
RUN go get goji.io
RUN go get gopkg.in/mgo.v2
# RUN cd $SRC_DIR; go build -o main
CMD ["go", "run", "/app/main.go"]

If I run the code for main.go outside of a container it runs as expected, however if I try to run the container as part of docker-compose I get an exit 0. I have seen other threads on stackoverflow that have suggested using stdin_open and tty, but these have not helped. I have also tried creating an .env file in the same directory I issue docker-compose up from with COMPOSE_HTTP_TIMEOUT=8000 in it and this has not worked either. I am looking for helped and suggestions as to what I need to do in order for my api container to stay up.

I know that --verbose can be issued with docker-compose, however I'm not sure what I should be looking for in the output that this produces.

I finally managed to get to the bottom of this, in my code which worked outside of a container I had:

http.ListenAndServe("localhost:8080", mux)

the fix was to simply remove localhost such that I now have:

http.ListenAndServe(":8080", mux)
