I have a running Kubernetes cluster consists of 3 nodes and one mater running on a VPS server, each node and master has its own public IP and floating IP also assigned to it and all these IPs are different from other
I am trying to configure metallb as a load balancer for my Kubernetes cluster but I don't know how can I set the metalLb IPs to range in the configuration file
here are the IPs examples of my servers
as you can see here, each IP is different so how can I set the Ip ranges in metallb config map?
Here an example of a config map
apiVersion: v1
kind: ConfigMap
metadata:
namespace: metallb-system
name: config
data:
config: |
address-pools:
- name: default
protocol: layer2
addresses:
- PUBLIC_IP-PUBLIC_IP
In the Metallb documentation there is a mention you can use certain IPs metallb.universe.tf/address-pool. See here
apiVersion: v1
kind: Service
metadata:
name: nginx
annotations:
metallb.universe.tf/address-pool: production-public-ips
spec:
ports:
- port: 80
targetPort: 80
selector:
app: nginx
type: LoadBalancer
The production-public-ips must be configured as showed here.
To configure MetalLB, you should create a configmap with your ips. Since you don't have the range, you can set /32 as subnet for your ips, like the example below.
apiVersion: v1
kind: ConfigMap
metadata:
namespace: metallb-system
name: config
data:
config: |
address-pools:
- name: production-public-ips
protocol: layer2
addresses:
- 115.203.150.255/32
- 94.217.238.58/32
- 46.12.5.65/32
- 76.47.79.44/32
It should work for your scenario.
