Configuring Cilium CNI¶
Prerequisites¶
Before you being configuring Cilium CNI, make sure the following prerequisites are met:
- BIG-IP is licensed and set up as a cluster.
- The networking setup is already complete.
- Supported Cilium Version v1.12.0 or newer.
- Linux version v5.2.0 or newer on all nodes of a Kubernetes cluster.
- Supported CIS version of v2.10.0 or newer.
- Validated Kubernetes Version: v1.24.3
- Cilium CNI is successfully installed and able to allocate a Pod IPaddress from Cilium CNI.
Creating VXLAN Tunnels on Kubernetes Cluster for Cilium CNI¶
CIS supports Cilium CNI only in a ClusterIP Deployment. See Deployment Options for more information.
Create a VXLAN profile. In the example below, the profile name is
cilium-vxlan-profile
.tmsh create net tunnels vxlan cilium-vxlan-profile port 8472 flooding-type multipoint
Create a VXLAN tunnel.
tmsh create net tunnels tunnel cilium-vxlan-tunnel-mp key 2 profile cilium-vxlan-profile local-address 10.4.1.59 remote-address any
Create the VXLAN tunnel self IP.
tmsh create net self cilium-selfip address 10.1.5.15/255.255.0.0 allow-service none vlan cilium-vxlan-tunnel-mp
Create a default route to route traffic through vxlan-tunnel (i.e. vxlan-tunnel-mp) interface to podCIDR Network of kubernetes cluster.
tmsh create net route ciliumRoute network 10.0.0.0/16 interface cilium-vxlan-tunnel-mp
Note
CIS creates only FDB entries. ARP entries of the cluster pods are learned dynamically by BIG-IP.
