Primary ENI IP #15

Closed C45tr0 closed 6 years ago

C45tr0 commented 6 years ago

It looks like the Primary ENI IP is allocated, but not used as a podIP.

This would not be an issue on bigger servers with more interfaces and IPs per interface, or even more servers, but starting out small this removes precious resources.

Is there a reason for this or would it be possible to change this behavior?

Would be willing to do a PR if this can be done and is a good idea.

This should probably be fixed (allocate interface, locate free). Right now we do not have dramatic wastage in production as we use the cni-ipvlan-vpc-k8s-tool new-interface invocation at cloud-init to allocate a secondary adapter, however subsequent adapters will still be leak one address on the first pass.

Merged in #17 to fix this.
