无法在Docker上运行Golang应用程序

I am trying to run this project - https://github.com/JumboInteractiveLimited/codetest

I've downloaded the Docker tool box, and I've executed the build and run commands as mentioned on the GitHub page, but when I try to access http:localhost:8080, the page is still unavailable.

When I try to execute run again, Docker says

"$ ./run.sh
Listening on http://localhost:8080
C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon:    driver failed programming external connectivity on endpoint quirky_mcnulty (32af4359629669ee515cbc07d8bbe14cca3237979f37262882fb0288f5d6b6b8): Bind for 0.0.0.0:8080 failed: port is already allocated."

Edit: To clarify, I get that error only when I run the 2nd time. When I ran the run command first, it didn't complain. I ran it another time just to confirm that it's running.

When I initially ran, I got the following:

$ ./run.sh
Listening on http://localhost:8080

    Change run.sh to replace port 8080 to 8082

    #!/bin/bash
    echo "Listening on http://localhost:8082"
    docker run -p 8082:80 codetest
    

    I have changes port to 8082 if the port is already in use change that port again to some other port based on your available port.

    If you are on Windows

    netsh interface portproxy add v4tov4 listenport=8082 listenaddress=localhost connectport=8082 connectaddress=192.168.99.100(IP of the Docker)
    

    Here is the helping discussion on port farwarding in windows with docker Solution for Windows hosts

    The issue seems quite clear

    port is already allocated
    

    which means that some other program is listening on port 8080. If you are on a Linux system you can try to run

    sudo lsof -i :8080
    

    to find out what is.

    Otherwise, simply use another port.
