Grasshopper is an implementation of the Nulecule Specification. It can be used to bootstrap container applications and to install and run them. Grasshopper is designed to be run in a container context.
Grasshopper is packaged as a container. End-users typically do not install
the software from source. Instead use the Grasshopper container as the FROM
line in your Dockerfile and package your application on top. For example:
FROM goern/grasshopper:0.2.0
MAINTAINER Your Name <you@example.com>
ADD /Nulecule /Dockerfile README.md /grasshopping/
ADD /artifacts /grasshopping/artifactsTo install your newly nuleculized application, simply call atomic run myapp.
For a description of the lifecycle of a Nulecule, please refer to FIXME
First of all, clone the github repository: git clone https://github.com/goern/grasshopper.
To build a Grasshopper base image just run make image, this will compile the
Grasshopper binary and generate a Docker container image containing it.
Grasshopper is also build on Fedora’s wonderful COPR build service, therefor a SPEC file is provided.

Warning

Nevertheless a source RPM is provided containing all the source from
github, the rpm build process itself is using go get to get the source.
