Following are the instructions for an all-in-one setup where Kubernetes will also be running inside the same Nova VM in which Kuryr-controller and Kuryr-cni will be running. 4GB memory and 2 vCPUs, is the minimum resource requirement for the VM:
To install OpenStack services run devstack with devstack/local.conf.pod-in-vm.undercloud.sample
.
Ensure that “trunk” service plugin is enabled in /etc/neutron/neutron.conf
:
[DEFAULT]
service_plugins = neutron.services.l3_router.l3_router_plugin.L3RouterPlugin,neutron.services.trunk.plugin.TrunkPlugin
Launch a VM with Neutron trunk port.. The next steps can be followed: Boot VM with a Trunk Port.
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
.
but first fill in the needed information:
Point to the undercloud deployment by setting:
SERVICE_HOST=UNDERCLOUD_CONTROLLER_IPFill in the subnetpool id of the undercloud deployment, as well as the router where the new pod and service networks need to be connected:
KURYR_NEUTRON_DEFAULT_SUBNETPOOL_ID=UNDERCLOUD_SUBNETPOOL_V4_ID KURYR_NEUTRON_DEFAULT_ROUTER=router1Ensure the nested-vlan driver is going to be set by setting:
KURYR_POD_VIF_DRIVER=nested-vlanOptionally, the ports pool funcionality can be enabled by following: How to enable ports pool with devstack.
[OPTIONAL] If you want to enable the subport pools driver and the VIF Pool Manager you need to include:
KURYR_VIF_POOL_MANAGER=True
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 binding section:
[binding] driver = kuryr.lib.binding.drivers.vlan link_iface = <VM interface name eg. eth0>Restart kuryr-k8s-controller:
sudo systemctl restart devstack@kuryr-kubernetes.serviceRestart kuryr-daemon:
sudo systemctl restart devstack@kuryr-daemon.service
Now launch pods using kubectl, Undercloud Neutron will serve the networking.
