# This Vagrantfile sets up a bazel based VM for building istio code, while
# sharing the source folder with the host VM. Within the VM, run
# bin/init.sh to generate the go vendor directories. Once done, you can use
# your favorite IDEs in the host machine for hacking on Istio go
# code. However, builds should always be done inside the Vagrant VM.  Make
# sure to setup a separate minikube VM, and ensure that its accessible from
# the bazel VM when running integration tests.
