On May 25 2019, a security relevant bug has been reported to us via the documented security disclosure channel. It was soon identified that multiple vendors are affected by this vulnerability. This lead to an embargo period which is being lifted today. The bug allows, under certain circumstances, to bypass network security policies. See below for details on the vulnerability and the mitigation.
As with everything we do, we are fully transparent. As it becomes obvious that a simple resolution in this matter is not possible, we follow open source best practices and choose a public forum for the sake of transparency. It was brought to our attention that some of the new eBPF code committed to the Calico repository is violating the license of source code in the Cilium repository.
Back in March we have asked our users to provide feedback via our first ever user survey. Many of you have responded and the results are in!
We are excited to announce the Cilium 1.5 release. Cilium 1.5 is the first release where we primarily focused on scalability with respect to number of nodes, pods and services. Our goal was to scale to 5k nodes, 20k pods and 10k services. We went well past that goal with the 1.5 release and are now officially supporting 5k nodes, 100k pods and 20k services. Along the way, we learned a lot, some expected, some unexpected, this blog post will dive into what we learned and how we improved.
This is a deep dive into ClusterMesh, Cilium's multi-cluster implementation.
We are excited to announce the Cilium 1.4 release. The release introduces several new features as well as optimization and scalability work. The highlights include the addition of global services to provide Kubernetes service routing across multiple clusters, DNS request/response aware authorization and visibility, transparent encryption (beta), IPVLAN support for better performance and latency (beta), integration with Flannel, GKE on COS support, AWS metadata based policy enforcement (alpha) as well as significant efforts into optimizing memory and CPU usage.
