The latest News and Information on Containers, Kubernetes, Docker and related technologies.
LogicMonitor recently released LM Container Argus v4 and has made monitoring Kubernetes clusters even easier. We have updated our Add Kubernetes Cluster wizard to make customization easier in the installation process. Start by going through the normal configuration settings, and then you will have the option to edit additional configuration settings to the CollectorSet Controller and Argus YAML files.
Earlier this month the Kubernetes project discovered a security issue affecting multitenant clusters: If a potential attacker can already create or edit services and pods, then they may be able to intercept traffic from other pods (or nodes) in the cluster. An attacker that is able to create a ClusterIP service and set the spec.externalIPs field can intercept traffic to that IP.
Prometheus is an essential element in DevOps. It has one of the largest contributor communities in the open source world and is the favorite database for time-series metrics data. It is also part of Logz.io’s complete observability package, which integrates open source grafana, Jaeger, and ELK Stack into one platform. It’s a favorite for system and container monitoring. This tutorial will show you how Prometheus works with Docker and your local machine.
The Domain Name System (DNS) is a naming system for computers, services, or other resources connected to the Internet or a private network. DNS translates domain names to the numerical IP addresses needed for locating and identifying computer services and devices. For decades It’s been an essential component of the Internet. It’s an essential part of Kubernetes as well, and is used to determine how workloads connect to Kubernetes services as well as resources outside the cluster.
On December 9th, 2020, I had the pleasure of speaking with two great minds on the topic of simplifying storage in Kubernetes. Alex Chircop is the Founder and CEO at StorageOS (https://storageos.com), and Bruno Andrade is the Founder and CEO at Shipa (https://www.shipa.io). The full recording of this discussion is below. Here is a summary of what we discussed: Simplify Deploying and Operating Stateful Applications within Kubernetes
