Rancher 2.2 Hits the GA Milestone
We released version 2.2.0 of Rancher today, and we’re beyond excited. The latest release is the culmination of almost a year’s work and brings new features to the product that will make your Kubernetes installations more stable and easier to manage.
Logging Kubernetes on GKE with the ELK Stack and Logz.io
An important element of operating Kubernetes is monitoring. Hosted Kubernetes services simplify the deployment and management of clusters, but the task of setting up logging and monitoring is mostly up to us. Yes, Kubernetes offer built-in monitoring plumbing, making it easier to ship logs to either Stackdriver or the ELK Stack, but these two endpoints, as well as the data pipeline itself, still need to be set up and configured.
Monitoring StatsD: metric types, format & code examples
The StatsD stack is one of the most popular monitoring solutions to instrument your code using custom metrics. In this post we will describe the StatsD metrics architecture, metrics types and formats, proving code examples for the Golang, NodeJS/Javascript and Python programming languages.
What you need to know to successfully run databases in production on Kubernetes
The Kubernetes community has made significant progress when it comes to easily deploying stateful services like databases. But what happens on Day 2? Day 2 operations are all about managing an application when things go wrong: nodes fail, networks are partitioned, a CVE comes out requiring a new version of Kubernetes to be deployed and all running apps upgraded.
What's New in Prometheus 2.8: WAL-Based Remote Write
Six months in the making, Write-Ahead Logging (WAL) for the remote_write API was one of the enhancements we included in the Prometheus 2.8 release on March 12. It’s a change intended to safeguard client metrics in the face of any network issues.
Container compliance for Docker and Kubernetes
Container compliance for Docker and Kubernetes is an essential part of enterprise security. It’s important for your environments, no matter where they reside, to remain compliant with industry regulation and/or company security policy.
Detecting and preventing cgroups escape via SCTP - CVE-2019-3874
This week CVE-2019-3874 was discovered which details a flaw in the Linux kernel where an attacker can circumvent cgroup memory isolation using the SCTP socket buffer. In containerised environments, this has the potential for a container running as root to create a DoS.
What's new in Kubernetes 1.14?
As it is already a tradition, here we are with What’s new for Kubernetes 1.14. Here at Sysdig we follow the Kubernetes development cycle closely in order to bring you a sneak peak of the enhancements and new features that Kubernetes 1.14 will contain when released on March 25, 2019.
Configuring Route Reflectors in Calico
Calico is a popular CNI plugin for Kubernetes. It leverages Border Gateway Protocol (BGP) for communicating routes available on nodes. This method fosters a highly scalable networking model between our workloads.
