Fleet is new open source project from the team at Rancher focused on managing fleets of Kubernetes clusters. Ever since Rancher 1.0, Rancher has provided a central control plane for managing multiple clusters. As pioneers of Kubernetes multi-cluster management, we have seen firsthand how users have consistently increased the number of clusters under management. We are already seeing interest from users who want to manage tens of thousands or even millions of clusters in the near future.

Security is one of the most talked-about topics for Kubernetes users. Google “Kubernetes security” and you’ll find a huge number of articles, blogs and more. The reason is simple: you need to align your container and Kubernetes security with your organization’s existing security profile. Kubernetes has some strong security best practices for your cluster—authentication and authorization, encryption in secrets and objects in the etcd database—to name a few. However, you need to be aware of other risks, such as privilege escalation and secrets obtained.

The k3s project was started by Darren Shepherd, Chief Architect at Rancher 7 months ago and has already become one of the most popular Kubernetes options on the CNCF Landscape by number of GitHub stars. To put this into context, k3s is more popular than OpenShift by IBM/Red Hat and only Rancher Kubernetes itself is more popular than k3s. Now stars are indicative of interest and popularity only and that should be noted.

Support for relational databases is a growing focus for Kubernetes users, and the release of Windows Server 2019 is expanding options for .NET applications and SQL Server. SQL Server workloads, however, often rely on Active Directory and Windows Auth, and storage arrays, which will not be supported by SQL Server containers on Windows Server 2019. Fortunately, a new Rancher Labs partner, Windocks, offers new options for SQL Server on Kubernetes and Rancher.

Today we announced releases v2.1.6 and v2.0.11 to address two security vulnerabilities recently discovered in Rancher. The first vulnerability allows users in the Default project of a cluster to escalate privileges to that of a cluster admin through a service account. The second vulnerability allows members to have continued access to create, update, read, and delete namespaces in a project after they have been removed from it. You can view the official CVEs here CVE-2018-20321 and here CVE-2019-6287.
