A Nix Flake to package a hello world GO application providing a development shell and minimal Docker image

Enter the devshell

$ nix develop

Run the GO application directly

$ go run main.go

(First time only) Initialize the GO module

$ go mod init example.com/hello
$ go mod tidy

Build the GO application

$ go build -o hello
$ ./hello

Alternatively, build the GO application using Nix

$ nix build
$ ./result/bin/hello

Bundle the GO application into a Docker image

$ nix build .#dockerImage
$ docker load < result
$ docker run -p 8080:8080 hello:latest
