[![Build](https://github.com/jeremyhuiskamp/golang-docker-scratch/workflows/build/badge.svg)](https://github.com/jeremyhuiskamp/golang-docker-scratch/actions?query=workflow%3Abuild)

A recipe for go binaries in a scratch docker container with

up-to-date tls certs and timezone data.

Golang binaries pair well with the docker scratch image, but

sometimes they need some help.  In particular, it is common to

need a TLS certificate database and timezone data.

Many tutorials suggest checking these files into your source

control, but this puts a maintenance burden on you to keep them

current.

This recipe leverages docker multistage builds to source the

data from the latest version of the alpine linux package repository

without needing the rest of alpine in the final image.

## Instructions

```

docker build -t golang-scratch-test --pull . && docker run -it --rm golang-scratch-test

```

## External tzdata

The default Dockerfile uses [time/tzdata](https://golang.org/pkg/time/tzdata/)

to embed the zone info included in the go distribution.

`Dockerfile.externaltz` shows an example of how to source the zone database

from alpine instead.  The external database takes up a bit more space but might

be desirable if, eg, you are stuck on an old golang version for some reason but

need a more current database, or want to use it from multiple go binaries in

the same image.
