The topic of setting up Kubernetes on AWS (including the use of the AWS cloud provider) is a topic I’ve tackled a few different times here on this site (see here, here, and here for other posts on this subject). In this post, I’ll share information provided to me by a reader, Christian Del Pino, about setting up Kubernetes on AWS with kubeadm but using manual certificate distribution (in other words, not allowing kubeadm to distribute certificates among multiple control plane nodes). As I pointed out above, all this content came from Christian Del Pino; I’m merely sharing it here with his permission.
This post specifically builds upon this post on setting up an AWS-integrated Kubernetes 1.15 cluster, but is written for Kubernetes 1.17. As mentioned above, this post will also show you how to manually distribute the certificates that kubeadm generates to other control plane nodes.
What this post won’t cover are the details on some of the prerequisites for making the AWS cloud provider function properly; specifically, this post won’t discuss:
I published a blog post describing how complex the underlay supporting VMware NSX still has to be (because someone keeps pretending a network is just a thick yellow cable), and the tweet announcing it admittedly looked like a clickbait.

Martin Casado quickly replied NO (probably before reading the whole article), starting a whole barrage of overlay-focused neteng-versus-devs fun.

In a MySQL master-slave high availability (HA) setup, it is important to continuously monitor the health of the master and slave servers so you can detect potential issues and take corrective actions. In this blog post, we explain some basic health checks you can do on your MySQL master and slave nodes to ensure your setup is healthy. The monitoring program or script must alert the high availability framework in case any of the health checks fails, enabling the high availability framework to take corrective actions in order to ensure service availability.
When having a business requirement of tenancy, most solutions will tend to lean towards VRF. That is because VLANs require a distributed L2 environment, which comes with spanning tree, mlag and a whole other glut of inefficient network control plane protocols. Upleveling the infrastructure to L3 ends up requiring VRF technology to enforce tenancy.
Once you’ve settled on this feature as the solution for the business requirement, the next question is: How do I successfully deploy VRFs in a large distributed environment at scale, that also allows me to minimize the burden of management while still enforcing tenancy in all the important parts of my network? Most conversations surrounding this question will lead down two solution paths:
VXLAN with EVPN leverages VRFs at every border and leaf switch, while all the intermediate devices (ie. spines, super spines) only see the encapsulated VXLAN traffic, and hence do not need any VRF intelligence or visibility.
A VRF Lite solution is fundamentally simpler since it uses less moving parts. The thought of enabling the EVPN address family and encapsulating traffic into a VXLAN tunnel Continue reading
