Running app in standalone container

1. Build and run image.

    docker build --no-cache -t eyeezzi/horus-api-server .
    docker run -d --env-file=.env -p 5000:80 eyeezzi/horus-api-server
   

   Note: The server runs on port 80, but we expose it as 5000 on the host in order to avoid privilege issues with binding to low number ports. Knowledge bit: port-mapping cannot be set in dockerfile.

2. View the logs generated by the app

    docker ps
    docker logs -f <container-name>
   
    # From another terminal on the host machine, test the server
    curl http://localhost:5000/api/v1/tokens
   

Dev Notes

To quickly test a container

docker build -t <image-name> --no-cache . \
    && docker run -it -v $(pwd)/src:/usr/src/app <imgage-name> sh

docker build -t api-server --no-cache . \
    && docker run -it -v $(pwd)/src:/usr/src/app api-server sh

The -v flag maps host absolute path to container absolute path.
