<p>AWS EKS makes use of their own CNI plugin and there are <a href="https://docs.aws.amazon.com/eks/latest/userguide/calico.html" rel="nofollow noreferrer">docs</a> that allow you to install Calico for managing policy.  For a number of reasons, I'd like to have Calico manage networking as well.</p>

<p>Based on the <a href="https://docs.projectcalico.org/v3.2/getting-started/kubernetes/installation/calico" rel="nofollow noreferrer">installation instructions</a> I can't seem to find a way to do either option:</p>

<h2>etcd</h2>

<p>Doesn't seem viable as I can't find a way to access the EKS control plane etcd endpoints. If I were to deploy my own etcd pods inside the cluster, I need to use the AWS CNI plugin for those to get an IP address, so that doesn't work. I could bring my own etcd cluster outside of Kubernetes, but that seems a bit ridiculous. </p>

<h2>Kubernetes API datastore</h2>

<p>This option wants me to change setting to the controller which I don't have access to in the AWS EKS managed control plane.</p>

<p>The short answer is as of this writing EKS (nor GKE) doesn't give you direct access to any of the control plane components: etcd, kube-apiserver, kube-controller-manager, coredns/kube-dns, kube-scheduler.</p>

<p>They do have some <a href="https://docs.aws.amazon.com/eks/latest/userguide/calico.html" rel="nofollow noreferrer">docs</a> on how to install Calico on an EKS cluster, but if you want more control you'll have to set up your own standalone cluster.</p>

<p>They might allow you access to the master components in the future but the bottom line is that EKS is a 'managed' service where they are supposed to take care of all your control plane components.</p>
