New applications and workloads are constantly being added to Kubernetes clusters. Those same apps need to securely communicate with resources outside the cluster behind a firewall or other control point. Firewalls require a consistent IP, but routable IPs are a limited resource that can be quickly depleted if applied to every service.
Rancher 2.4, the latest release of Rancher’s Kubernetes management platform, includes a new CIS security scanning feature. The Center for Internet Security publishes more than 100 benchmarks for Kubernetes, which are considered the default standard benchmark for defining security of Kubernetes clusters. With Rancher 2.4, CIS scanning is an integrated part of the Rancher UI itself for RKE clusters. If you create or import any RKE cluster via Rancher, CIS Scan will work flawlessly.
Data science has exploded as a practice in the past decade and has become an undisputed driver of innovation. The forcing factors behind the rising interest in Machine Learning, a not so new concept, have consolidated and created an unparalleled capacity for Deep Learning, a subset of Artificial Neural Networks with many “hidden layers”, to thrive in the years to come.
This article explores how we can reverse engineer Docker images by examining the internals of how Docker images store data, how to use tools to examine the different aspects of the image, and how we can create tools like Dedockify to leverage the Python Docker API to create Dockerfiles from source images.
Kubernetes is an open source-system for managing containerized applications across multiple hosts. It aims to provide a “platform for automating deployment, scaling, and operations of application containers across clusters of hosts.” Originally developed by Google, it is now maintained by the Cloud Native Computing Foundation (CNCF).
Optimization and validation bring hands-free infrastructure for Kubernetes in public and hybrid clouds to Red Hat OpenShift customers 21 May, 2020 — Spot, a leading provider of software for modern CloudOps, today announced that Ocean by Spot has achieved Red Hat Operator certification for OpenShift.
This week, Canonical announced the integration of Charmed Kubernetes with Microsoft Azure Arc. This integration provides businesses with a centralised place to manage their Kubernetes clusters and deploy their applications at scale, from cloud to the edge. The Azure Arc dashboard enables management and governance of any Kubernetes, across any substrate.
A Prometheus CloudWatch exporter is a key element for anyone wanting to monitor AWS CloudWatch. Exporting CloudWatch metrics to a Prometheus server allows leveraging of the power of PromQL queries, integrating AWS metrics with those from other applications or cloud providers, and creating advanced dashboards for digging down into problems. But, who watches the watcher? Despite those advantages, using the wrong exporter or an incorrect configuration can have bad consequences in production environments.
The promise of Kubernetes is to empower your organization to quickly deliver applications and services to your customers. Delivering fast cycle time and innovation requires developers and operators to collaborate effectively to ensure safety while moving fast. The GitOps methodology has taken hold in the Kubernetes ecosystem to deliver on this promise. What is GitOps? GitOps provides a mechanism to safely deploy Kubernetes manifests stored in a Git repository.
Hey there. Welcome to the fifth and final installment in our series on successfully deploying an app to AWS with the least effort. This week, we'll discuss things you need to worry about now that you've released, plus optimizing your app. Ok, so you've released your app. Congrats! However, we both know your work doesn't end here. You should continue improving your app, both on the end-user side and the back end.
