This contains code to run Go on the Rumprun unikernel.
Rumprun is a special project because it allows you to run your Go apps unmodified directly on the hypervisor of your choice such as KVM or Xen.
This allows faster boot times, smaller images and a much smaller attack surface for security.
We believe unikernels are the future of infrastructure.
This repo is based on Go the source 1.5.1 stable c7d78ba4df574b5f9a9bb5d17505f40c4d89b81c downloaded at https://storage.googleapis.com/golang/go1.5.1.src.tar.gz .
On top, the NetBSD platform has been modified to support Rumprun instead.
To generate a patch: git diff go-1-5-1-upstream master.
We don't intend to fork Go but there's quite a lot of work to do to get it in enough shape to put into the main tree.
You can find the latest build of the modified Go @ https://s3.amazonaws.com/dp-gorump/gorump.tar.gz .
Please submit pull requests!
See examples directory on how to build and use.
There are 2 ways you can install - from apt-get or by downloading the source and the rumprun source and building it yourself.
