Finding all the number of ip addresses used in eks with fargate

Can we use Amazon-vpc-cni-k8s network plugin in cluster created with kubeadm tool?

QUESTION

Finding all the number of ip addresses used in eks with fargate

Asked 2022-Feb-09 at 11:09

I am trying to understand the usage of the ip addresses from my vpc in the eks with fargate environment. I can see that each pod has its own private ip address, which seems to be the same ip address for fargate node as well. It seems that the ENI allocates a single primary address for a EC2 node and many ip address as secondary based on the size, but I cannot find the same information on fargate. Does that mean it does not have any secondary ip addresses allocated ?

Extending on the question, it seems that a network load balancer requires a minimum of 8 free ip addressses to be created, Does that mean it blocks all the 8 ?

...Does that mean it does not have any secondary ip addresses allocated ?

Correct, since you can only run 1 pod on each Fargate instance, while on EC2 node you can run many pods.

...Does that mean it blocks all the 8 ?

The LB controller won't block subnet IP. When you make request to create NLB in a subnet that has insufficient IP, you will see error message like: ..."error":"InvalidSubnet: Not enough IP space available in subnet-.... ELB requires at least 8 free IP addresses in each subnet. Note this is a requirement of ELB and not EKS.

Asked 2020-May-26 at 13:19

I have a Kubernetes cluster created using kubeadm tool in AWS instance. I used the "Weave" Network plugin. I just saw amazon-vpc-cni-k8s plugin in EKS Documentation. So can I use this Network plugin in my cluster created by kubeadm tool?

No, you would need to separately run the amazon-vpc-cni-k8s command.

kubectl apply -f aws-k8s-cni.yaml from here

Alternatively you could use Kubespray that allows you to configure the CNI plugin as part of the deployment

Install amazon-vpc-cni-k8s

Download the latest version of the yaml and apply it the cluster. Launch kubelet with network plugins set to cni (--network-plugin=cni), the cni directories configured (--cni-config-dir and --cni-bin-dir) and node ip set to the primary IPv4 address of the primary ENI for the instance (--node-ip=$(curl http://169.254.169.254/latest/meta-data/local-ipv4)). It is also recommended to set --max-pods equal to (the number of ENIs for the instance type × (the number of IPs per ENI - 1)) + 2; for details, see vpc_ip_resource_limit.go. Setting --max-pods will prevent scheduling that exceeds the IP address resources available to the kubelet. The default manifest expects --cni-conf-dir=/etc/cni/net.d and --cni-bin-dir=/opt/cni/bin. Alternatively there is also a Helm chart: eks/aws-vpc-cni.
