This is a simple demo app that can be used to identify the different build versions of the application as well as the environment they are running in.
A Dockerfile is included so you can build container images. Alternatively, you can use Go to build it using go build.
Whether you run the binary directly, or through a container image, you can set the ENVIRONMENT environment variable to alter the name that appears in the application. The GitHub SHA is taken from the latest git commit as of building.
