gRPC in the Real World: The Kubernetes Container Runtime Interface

In this article we’re going to look at how gRPC is used by Kubernetes in its Container Runtime Interface (CRI) technology. Bit first, why aren’t we seeing that much gRPC on the front-end? It’s a question that’s been asked many times now and it is one that is well worth answering. In previous installments of […]

Yes, you can run VMs on Kubernetes with KubeVirt

Containers and Kubernetes are awesome technologies that enable applications to run without a heavy operating system (OS), as using a virtual machine (VM) would require. Container-first, cloud-native applications are the future, but not every application is suitable to be cloud-native. KubeVirt allows you to run your virtual machines alongside your containers on a Kubernetes platform. […]

How Alibaba Cloud uses Cilium for High-Performance Cloud

A couple of weeks ago, the Alibaba team presented details on the new datapath for the Alibaba Cloud during the SIG Cloud-Provider-Alibaba meeting and also published a blog post with the technical architecture. Guess what, it is all Cilium & eBPF based. Alibaba Cloud is not the first cloud provider to directly embed Cilium. Recently, […]

How to perform a CNI Live Migration from Flannel+Calico to Cilium

Container Network Interface (CNI) is a big topic, but in short, CNI is a set of specifications that define an interface used by container orchestrators to set up networking between containers. In the Kubernetes space, the Kubelet is responsible for calling the CNI installed on the cluster so Pods are attached to the Kubernetes cluster […]

3 Years of Kubernetes in Production–Here’s What We Learned

We started out building our first Kubernetes cluster in 2017, version 1.9.4. We had two clusters, one that ran on bare-metal RHEL VMs, and another that ran on AWS EC2. Today, our Kubernetes infrastructure fleet consists of over 400 virtual machines spread across multiple data-centres. The platform hosts highly-available mission-critical software applications and systems, to […]

Amazon EKS now supports assigning EC2 security groups to Kubernetes pods

Amazon Elastic Kubernetes Service (EKS) customers can now leverage EC2 security groups to secure applications with varying network security requirements on shared cluster compute resources. Previously, all pods on a node shared the same security groups. While IAM roles for service accounts solves the pod level security challenge at the authentication layer, many organization’s compliance […]

Ingress for Anthos—Multi-cluster Ingress and Global Service Load Balancing

Ingress for Anthos is a Google cloud-hosted multi-cluster ingress controller for Anthos GKE clusters. Ingress for Anthos supports deploying shared load balancing resources across clusters and across regions enabling users to use a same load balancer with an anycast IP for applications running in a multi-cluster and multi-region topology. In simpler terms this allows users […]

What we learned after a year of GitLab.com on Kubernetes

It’s been one year since we moved GitLab.com to Kubernetes. We unpack the challenges and learnings from this major migration. For about a year now, the infrastructure department has been working on migrating all services that run on GitLab.com to Kubernetes. The effort has not been without challenges, not only with moving services to Kubernetes […]
