Upgrading Your AWS Kubernetes Cluster By Replacing It

With the recent panic over the zero-day Kubernetes vulnerability CVE-2018-1002105, Kubernetes administrators are scrambling to ensure their Kubernetes clusters are upgraded to a version that is patched for the vulnerability. As of this writing, the minimum versions that have the patch are 1.10.11, 1.11.5, 1.12.3, and 1.13.0-rc.1.

Infrastructure UI for Kubernetes and Docker using Elasticsearch and Kibana

The Elastic Stack comes with powerful data visualization capabilities. Filebeat and Metricbeat modules, as well as, Elastic APM ship with pre-built Kibana dashboards that serve as a great starting point for exploring logs, metrics, and APM data in Kibana. On top of that, the Infrastructure, Logs, and APM UIs enable common workflows for correlating the data coming from different operational contexts.

Introducing Sysdig Secure 2.2: Kubernetes auditing, compliance, and access control.

Over the past four years we’ve helped hundreds of organizations run reliable, secure, and compliant Kubernetes and Openshift clusters. Some of the key themes we’ve seen from organizations that have successfully grown their Kubernetes footprint are: they have immaculate labeling, understand how to leverage internal Kubernetes features to harden their platform, and understand what developers need access to and manage it with RBAC and namespaces.

Container security orchestration with Falco and Splunk Phantom

Container security orchestration allows to define within your security policy how you are going to respond to your different container security incidents. These responses can be automated in what is called security playbooks. This way, you can define and orchestrate multiple workflows involving different software both for sourcing and responding. This is how Falco and Splunk Phantom can be integrated together to do this.

Service based access control with Sysdig Secure Teams

While you’re likely familiar with role-based access control, Sysdig teams introduce the concept of service-based access control. With service-based access control, administrators can define groups of users that have access to policy events, policy configuration, and scanning data limited to a service or set of services, as defined by your orchestration system (think Kubernetes, Mesos, and the like).

How to Monitor Kubernetes Without an Agent on Every Node

LogicMonitor is an agentless monitoring solution. What we really mean by “agentless” is that we don’t require an agent on every monitored server (physical or virtual). One LogicMonitor Collector - a lightweight application that takes just seconds to install - can monitor hundreds or even thousands of devices, including servers, virtual machines, network switches, storage systems, cloud resources, containers, and more.

Streamlined Kubernetes Cluster Agent

Sematext provides a single pane of glass and machine learning powered alerts for logs, metrics, traces and digital user experience data. The new Sematext agent is fully Docker Engine and Kubernetes-aware. (Re)written in Go, it has a minimal memory and CPU footprint. It also collects Kubernetes metrics in the most optimal fashion possible.

Kubernetes in Production: Services

We migrated all of our services to Kubernetes about six months ago. At first glance, the task seemed quite simple: deploy a cluster, write application specifications, and that’s it. But, since we’re obsessed with stability, we nevertheless had to learn how k8s works under pressure, so we tested multiple failure scenarios. Most of the questions that arose were network related. One particular point of concern was how Kubernetes Services function.
