Calico in 2020: The World's Most Popular Kubernetes CNI

Calico and Kubernetes go hand-in-hand. Kubernetes is the de facto standard for deploying and managing container-based applications at scale, both on-premises and in the cloud. Calico continues to be the most popular open-source networking and network security solution for Kubernetes. Despite the cataclysmic events that occurred in 2020, the Calico community, supported by the team at Tigera, remained focused and achieved several major successes. We are excited to share these highlights.

New Vulnerability Exposes Kubernetes to Man-in-the-Middle Attacks: How to Mitigate CVE-2020-8554

A few weeks ago a solution engineer discovered a critical flaw in Kubernetes architecture and design, and announced that a “security issue was discovered with Kubernetes affecting multi-tenant clusters. If a potential attacker can already create or edit services and pods, then they may be able to intercept traffic from other pods (or nodes) in the cluster.” If a hostile user can create a ClusterIP service and set the spec.externalIP field, they can intercept traffic to that IP.

Automated, Simplified DNS Troubleshooting for Kubernetes: Only in Calico Enterprise

The Domain Name System (DNS) is a naming system for computers, services, or other resources connected to the Internet or a private network. DNS translates domain names to the numerical IP addresses needed for locating and identifying computer services and devices. For decades It’s been an essential component of the Internet. It’s an essential part of Kubernetes as well, and is used to determine how workloads connect to Kubernetes services as well as resources outside the cluster.

Enabling Secure Kubernetes Multi-Tenancy with Calico Enterprise

When you have different teams interacting with a Kubernetes cluster you need to think about the security, privacy, and observability challenges associated with multi-tenancy: How to provide each team with access to the specific resources they need, in a way that allows the team to be agile, without risking impacting other teams? In this session, we’ll explore the Kubernetes multi tenancy concepts and design patterns needed for successful enablement of multi-tenancy within your Kubernetes clusters using key capabilities of Calico Enterprise.

Getting Up and Running with Calico for Windows

Calico is the only cross-platform CNI and networking and network security policy engine available today. It currently powers more than 150,000 known clusters across millions of nodes worldwide. Calico is also unique in supporting multiple dataplanes: Standard Linux, eBPF, and Windows HNS. Many organizations have .NET and Windows workloads that they have or eventually will modernize and deploy to Kubernetes. However, this may be uncharted territory for teams that are using Windows. This session is intended to inform and ease your adoption of Kubernetes on the Windows platform.

Securing Kubernetes using Egress Access Controls

A majority of existing workloads are non-Kubernetes, and for the platform teams involved, this creates challenges because the cluster will need to be securely connected to those resources. Calico Enterprise includes several features that enable fine-grained access controls between your microservices and databases, cloud services, APIs, and other applications that may be protected behind a firewall. There are different approaches to managing Kubernetes egress access, depending on your needs and where you want the control point to be

Deploying Calico in Your On-prem Kubernetes Cluster: Networking and Security Considerations

If you are deploying Kubernetes on-premises in your datacenter, this is a talk and demo you won’t want to miss. Networking and security might not be the first things that come to mind, but without some understanding of the networking and security decisions you’ll need to make, and the right options for your environment, you’re likely to get stuck or make the wrong assumptions. These may limit your ability to scale or integrate with the rest of the datacenter network.

Tigera to Support Amazon EKS-Distro

Today, we are excited to announce our commitment to support Calico and Calico Enterprise for the Amazon EKS-Distro, a Kubernetes distribution based on and used by Amazon EKS. EKS-D enables you to create reliable and secure Kubernetes clusters using the same versions of Kubernetes and its dependencies deployed by Amazon EKS. We view EKS-D as further confirmation of the central role that Kubernetes plays in today’s IT infrastructure.
