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].
|
||||

||||

||||
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
