Debugging and Monitoring DNS issues in Kubernetes

DNS is a common cause for outages and incidents in Kubernetes clusters. For real-world stories, swing by Kubernetes Failure Stories. How do you debug and troubleshoot DNS issues? How do you know a problem is related to DNS? This guide provides a step by step tutorial on how to systematically troubleshoot DNS issues in Kubernetes clusters. We will be using [Hubble] to identify and inspect DNS issues as well as set up monitoring so we can locate DNS issues early on to react even before incidents occur.

CVE-2019-13119: Policy bypass via nested encapsulation

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.

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.
