Installation fail with conflict between the ports of the gateway and its load balancer

Hi @IceManGreen,

The issue is that both your lb and liqo gateway pods try to bind to the same port. If you change it in the values file, it is reflected on the pod and service.

You have two possible solutions:

• use node port services
• run the installation with the flag --set "gateway.service.type=LoadBalancer,gateway.config.listeningPort=5873" and then edit your service to listen the port 5871

We will fix this in the next release by avoiding the usage of host ports and host networks.

Thank you, it works indeed !

For anyone looking for a temporary solution for the LoadBalancer, what I did exactly is :

liqoctl install k3s --cluster-name domain-1 \
    --api-server-url <url> \
    --set "gateway.service.type=LoadBalancer,gateway.config.listeningPort=5873" \

(Like @aleoli said)

Then edit the LoadBalancer Daemonset with kubectl edit daemonset/svclb-liqo-gateway-2fe6dd49 -n kube-system (or according to the name of your daemonset) with :

# ...
spec:
 template:
   spec:
     containers:
     - env:
       - name: SRC_PORT
        # HERE >
         value: "5871"
       - name: SRC_RANGES
         value: 0.0.0.0/0
       - name: DEST_PROTO
         value: UDP
       - name: DEST_PORT
         value: "5873"
       - name: DEST_IPS
         value: 10.43.232.220
       image: rancher/klipper-lb:v0.4.5
       imagePullPolicy: IfNotPresent
       # HERE (to avoid confusions) >
       name: lb-udp-5871
       ports:
      # HERE (all the ports) >
       - containerPort: 5871
         hostPort: 5871
         name: lb-udp-5871
         protocol: UDP

Apply the modifications and watch the installation end with success :)

Perfect, closing this issue
