In this scenario you will learn how to run your Golang development environment inside a Docker container. We'll also discuss how to build a Docker image suitable for Golang applications.

This was created based on http://blog.benhall.me.uk

As demonstrated in this scenario, Makefiles make it really easy to manage the creation of Docker images. By having a single file you can organise the required commands for creating, debugging and releasing in a single and consistent approach.

NAME = ocelotuproar/docker-warden
INSTANCE = docker-warden

.PHONY: default build copy debug run release dev push

default: build

build:
    docker build -t $(NAME) .

copy:
    docker create --name $(INSTANCE) $(NAME)
    docker cp $(INSTANCE):/go/bin/app $(shell pwd)/build
    docker rm $(INSTANCE)

debug:
    docker run --rm -it --name $(INSTANCE) $(NAME) /bin/bash

run:
    docker run --rm --name $(INSTANCE) $(NAME)

dev:
    docker run -it --rm -w /go/src/github.com/$(NAME) -v $(shell pwd)/vendor/github.com/:/go/src/github.com/ -v $(shell pwd):/go/src/github.com/$(NAME) golang
