go-example

Description

This example builds a hello world application.

Build

The base golang:alpine Docker image is several hundred MBs in size, to run a tiny application. To make the smallest possible image, we'll build the application first and then copy it into a scratch base image.

Compile the application before building the image:

CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o bin/go-example .

docker build -t go-example .

Run

Run the following to run a container that will be removed when the command exits:

docker run -it --rm -p 8080:8080 go-example

Browse to http://localhost:8080 to test.
