How to try out nested-pods locally (MACVLAN)
|
|
============================================
|
|
|
|
Following are the instructions for an all-in-one setup, using the
|
|
nested MACVLAN driver rather than VLAN and trunk ports.
|
|
|
|
1. To install OpenStack services run devstack with ``devstack/local.conf.pod-in-vm.undercloud.sample``.
|
|
2. Launch a Nova VM with MACVLAN support
|
|
|
|
.. todo::
|
|
Add a list of neutron commands, required to launch a such a VM
|
|
|
|
3. Log into the VM and set up Kubernetes along with Kuryr using devstack:
|
|
- Since undercloud Neutron will be used by pods, Neutron services should be
|
|
disabled in localrc.
|
|
- Run devstack with ``devstack/local.conf.pod-in-vm.overcloud.sample``.
|
|
Fill in the needed information, such as the subnet pool id to use or the
|
|
router.
|
|
|
|
4. Once devstack is done and all services are up inside VM. Next steps are to
|
|
configure the missing information at ``/etc/kuryr/kuryr.conf``:
|
|
|
|
- Configure worker VMs subnet::
|
|
|
|
[pod_vif_nested]
|
|
worker_nodes_subnet = <UNDERCLOUD_SUBNET_WORKER_NODES_UUID>
|
|
|
|
- Configure "pod_vif_driver" as "nested-macvlan"::
|
|
|
|
[kubernetes]
|
|
pod_vif_driver = nested-macvlan
|
|
|
|
- Configure binding section::
|
|
|
|
[binding]
|
|
link_iface = <VM interface name eg. eth0>
|
|
|
|
- Restart kuryr-k8s-controller::
|
|
|
|
sudo systemctl restart devstack@kuryr-kubernetes.service
|
|
|
|
Now launch pods using kubectl, Undercloud Neutron will serve the networking.
