+vagrant-devstack-Kuryr-Kubernetes
+=================================
+
+Getting started
+---------------
+
+A Vagrant based kuryr,neutron,keystone,docker and kubernetes system.
+
+Steps to try vagrant image:
+
+ 1. Install Vagrant on your local machine. Install one of the current
+    providers supported: VirtualBox, Libvirt or Vagrant
+ 2. Git clone kuryr-kubernetes repository.
+ 3. Run `cd kuryr-kubernetes/contrib/vagrant`
+ 4. Run `vagrant up`
+    It will take from 10 to 60 minutes, depending on your internet speed.
+    Vagrant-cachier can speed up the process [2].
+ 5. `vagrant ssh`
+
+At this point you should have experimental kubernetes (etcdv3, k8s-apiserver,
+k8s-controller-manager, k8s-scheduler, kubelet and kuryr-controller), docker,
+kuryr, neutron, keystone all up, running and pointing to each other. Pods and
+services orchestrated by kubernetes will be backed by kuryr+neutron. The
+architecture of the setup can be seen at [1].
+
+References:
+[1] https://docs.openstack.org/developer/kuryr-kubernetes/devref/kuryr_kubernetes_design.html
+[2] http://fgrehm.viewdocs.io/vagrant-cachier/
+
+Vagrant Options available
+-------------------------
+
+You can set the following environment variables before running `vagrant up` to modify
+the definition of the Virtual Machine spawned:
+
+ * **VAGRANT\_KURYR\_VM\_BOX**: To change the Vagrant Box used. Should be available in
+   [atlas](http://atlas.hashicorp.com).
+
+       export VAGRANT_KURYR_VM_BOX=centos/7
+
+   Could be an example of a rpm-based option.
+
+ * **VAGRANT\_KURYR\_VM\_MEMORY**: To modify the RAM of the VM. Defaulted to: 4096
+ * **VAGRANT\_KURYR\_VM\_CPU**: To modify the cpus of the VM. Defaulted to: 2
+ * **VAGRANT\_KURYR\_RUN\_DEVSTACK**: Whether `vagrant up` should run devstack to
+   have an environment ready to use. Set it to 'false' if you want to edit
+   `local.conf` before run ./stack.sh manually in the VM. Defaulted to: true.
+   See below for additional options for editing local.conf.
+
+Additional devstack configuration
+---------------------------------
+
+To add additional configuration to local.conf before the VM is provisioned, you can
+create a file called "user_local.conf" in the contrib/vagrant directory of
+networking-kuryr. This file will be appended to the "local.conf" created during the
+Vagrant provisioning.
+
+For example, to use OVN as the Neutron plugin with Kuryr, you can create a
+"user_local.conf" with the following configuration:
+
+    enable_plugin networking-ovn http://git.openstack.org/openstack/networking-ovn
+    enable_service ovn-northd
+    enable_service ovn-controller
+    disable_service q-agt
+    disable_service q-l3
+    disable_service q-dhcp
