Use this repository in your Makefile by including it:

BINARY := metal-api
MAINMODULE := <your package>
COMMONDIR := $(or ${COMMONDIR},../../common)

include $(COMMONDIR)/Makefile.inc

release:: all ;

You have to:

• specify the BINARY name. This will be the generated binary, it will be placed in the bin folder.
• specify the MAINMODULE path. This path should point to the folder of your main.go
• specify the COMMONDIR is the directory where this repository is located. you MUST evaluate if there is an environment variable COMMONDIR and use this one, so that our CI server and multistage builds can set this path to another location than on your local pc.
• overwrite the release target (note the two colons after the target name). Normally you should set this to the all which compiles your go code. But sometimes you want to do something before compiling (generate code, etc.).

Now you can simply make to build a binary

You can use the image as a base builder image in your own Dockerfile:

FROM metalstack/builder:latest as builder

This base image wants you to have a go.mod and a Makefile where the default target creates the binary. This binary will be located in the path /work/bin/....
