Statically compiled tool to ingest json + erb and produce config files

erbmash

erbmash is a minimal wrapper around mruby-erb and mruby-yaml using the go-mruby bindings. It allows you to mash json or yaml input and erb templates together without a ruby runtime.

It is intended t be used in conjunction with other tools to provide the json or yaml data (e.g. etcdctl, consul, web services or manually written config).

Watch behaviour similar to confd should be possible using these external tools but I haven't played with that. A PR (or an issue if it's not possible) with examples would be appreciated if it works!

Usage

Usage is pretty simple: erbmash --data some_json_or_yaml_file --erb some_erb_file

See the examples directory for examples of templates.

Plans

I don't want to scope creep too much as the premise of the tool is really do one thing well.

Support may be added for the following:

• Producing several output files from a single run
• Encode json / yaml

Building

You will need docker, Go 1.6+, make and govendor installed. Note that the actual build happens in a docker container so no other host deps should be required.

go get -d github.com/mikesimons/go-mruby
govendor update github.com/mikesimons/go-mruby
make
