Today, Canonical announces full enterprise support for Kubernetes 1.21, from cloud to edge. Canonical Kubernetes support covers MicroK8s, Charmed Kubernetes and kubeadm. Starting with 1.21, moving forward Canonical commits to supporting N-2 releases as well as providing extended security maintenance (ESM) and patching for N-4 releases in the stable release channel.

Since the release of CVE-2020-8554 on GitHub this past December, the vulnerability has received widespread attention from industry media and the cloud security community. This man-in-the-middle (MITM) vulnerability affects Kubernetes pods and underlying hosts, and all Kubernetes versions—including future releases—are vulnerable. Despite this, there is currently no patch for the issue.

In my first post in the Kubernetes Logging Simplified blog series, I touched on some of the ‘need to know’ concepts and architectures to effectively manage your application logs in Kubernetes – providing steps on how to implement a Cluster-level logging solution to debug and analyze your application workloads. In my second post, I’m going to touch on another signal to keep an eye on: Kubernetes events.

System and application logs provide crucial data for operators and developers to troubleshoot and keep applications healthy. Google Cloud automatically captures log data for its services and makes it available in Cloud Logging and Cloud Monitoring. As you add more services to your fleet, tasks such as determining a budget for storing logs data and performing granular cross-project analysis can become challenging.

2020 was a difficult year for all of us, and it was no different for engineering teams. Many software releases were postponed, and the industry slowed its development speed quite a bit. But at least at AWS, some teams released updates out of the door at the end of the year. AWS Lambda received two significant improvements: With these two new features and Lambda Layers, we now have three ways to add code to Lambda that isn’t directly part of our Lambda function.

In April 2020, MalwareHunterTeam found a number of suspicious files in an open directory and posted about them in a series of tweets. Trend Micro later confirmed that these files were part of the first cryptojacking malware by TeamTNT, a cybercrime group that specializes in attacking the cloud—typically using a malicious Docker image—and has proven itself to be both resourceful and creative.

While containers are known for their multiple benefits for the enterprise, one should be aware of the complexity they carry, especially in large scale production environments. Having to deploy, reboot, upgrade or apply patches to patches to hundreds and hundreds of containers is no easy feat, even for experienced IT teams. Different types of Kubernetes solutions have emerged to address this issue.
