The latest News and Information on Containers, Kubernetes, Docker and related technologies.
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).
