Using docker and goa providing connection refused

Question

Hey all any help is very much appreciated, I have been stuck on this for a week now...

I am trying to put my golang backend api built by the framework goa inside of a docker container. When I build and run the go binary the server works as intended, I am able to go to my routes and see data being returned. As soon as I put the server in a docker container I get the ERR_CONNECTION_REFUSED / ERR_SOCKET_NOT_CONNECTED and I am very confused on what I am doing wrong.

Here is my Docker file

# Grab hardened go image from artifactory.
FROM golang:1.16.9-alpine 

# Set working directory to be inside the container.
WORKDIR /app
    
COPY . .

# Download all dependencies. 
RUN go build -o main ./cmd

#Expose the port
EXPOSE 8080

# Run the executable
CMD ["./main"]

Here is my netstat result

tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      -                   
tcp6       0      0 :::8080                 :::*                    LISTEN      -  

And lastly, this is when I run the container

[api] 21:43:17 HTTP "Auth" mounted on GET /api/auth
[api] 21:43:17 HTTP "Create" mounted on POST /api/user
[api] 21:43:17 HTTP "ReadByID" mounted on GET /api/user/{id}
[api] 21:43:17 HTTP server listening on "localhost:8080"

Any help is appreciated, let me know if I can provide any more details
