Introduction

Simple dockerfile to install jsonnet and go-jsonnet into a runnable container.

Usage

You can run the C++ binary directly with a command like:

docker run --rm -it -v `pwd`:/src mexisme/jsonnet jsonnet ${ARGS}

or, for the Go binary:

docker run --rm -it -v `pwd`:/src mexisme/jsonnet go-jsonnet ${ARGS}

Note that it will mount the current directory into the Docker image before running it, so if you're importing other Jsonnet files, they will need to a sub-dir of the current directory.

Shell Aliases:

You can add aliases to your profile to reduce typing. For example, in your ~/.zshrc add

alias jsonnet='docker run --rm -it -v `pwd`:/src mexisme/jsonnet jsonnet'
alias go-jsonnet='docker run --rm -it -v `pwd`:/src mexisme/jsonnet go-jsonnet'

Building

The Dockerfile and Makefile can build either Alpine Linux or Debian versions:

Make all:

make

Alpine:

make alpine

Debian:

make debian

Updating local copies of `jsonnet` and `go-jsonnet`:

In an attempt to stay reasonably hermetic, the Jsonnet code for C++ and Go has been vendored into the subrepo/ directory. This also helps Docker to decide when it needs to use a cached layer or re-run the build steps.

In order to update the contents of the vendored code, you must first install https://github.com/ingydotnet/git-subrepo and then run the following:

make update
