Kubernetes load balancer service

Hello,

I have enabled the Kubernetes service in a basic networking zone. When I try to create a k8s load balancer service, the external-ip never changes from pending.

What do I need to do to enable this feature?

Thanks,
-Stu

Hello,

Is it futile to configure Cloudstack advanced networking with systems with only one NIC and a dumb switch?

Thanks,
-Stu

The systems only have one NIC, and the switch does not support VLAN. Based on the email below, I gave advanced networking with vxlan a try.

I followed the vxlan plugin guide. Since I only have one NIC, I used the cloudbr0 as the guest network traffic label. A VM on an isolated guest network cannot ping a system on the physical network using a packet size of 2048. The default packet size works.

I tried to set the MTU of the cloudbr0 interface to 1550, but this did not change the result. In fact, it made it so I could not ping the host using a packet size of 2048.

Any ideas?

Hi Stu

Could you please try the Kubernetes service on Advance zone, instead of Basic zone.

AFAIK Kubernetes provider requires a advanced zone ( i.e Network with Loadbalancing rules)
