HelloWorldGoServer

An Example Go Application

https://github.com/td-harness/goHelloWorldServer

An example "Hello World" golang web application.

This README.md is constantly evolving.

I forked this work from td-harness who forked the original source from nofarb.

• https://github.com/td-harness
• https://github.com/nofarb

I made an attempt at simplifing the repository and content; removing tests, conflicts, etc, and structuring the same in such a way as to keep it very small and readable for my PPT presentation to Harness management.

Dependencies:

• go
• docker

Running the app locally

go build -o main .
./main

Hello, jbarfield
