The latest News and Information on Containers, Kubernetes, Docker and related technologies.
The Rancher community is 30,000+ strong and growing fast! In order to continue growing and nurturing our vibrant open source community, we’ve created the Trusted Ranch Hand Program. Trusted Ranch Hands are a select group of knowledgeable ranchers ready, willing, and able to help other Ranchers as we all adopt DevOps practices and principles using Rancher, Kubernetes, and related technologies that help us all Run Kubernetes Everywhere!
Unless you have been living under a rock, you have probably heard of Kubernetes, the open source container orchestration governed by the Cloud Native Computing Foundation. Kubernetes helps you focus on your applications by providing powerful abstractions and help solves many of the challenges of managing, deploying and scaling your containerized applications.
The history of technology, and Enterprise IT, in particular, is a story of trends colliding with trends. In the case of Kubernetes, we have the intersecting trends of cloud, microservices, and containerization adoption. The orchestration platform born in the juggernaut that is Google has become the focal point for all 3 of these trends. And why do companies care? Because it is life and death.
Oracle’s Container Engine for Kubernetes (OKE) is a service that helps you deploy, manage, and scale Kubernetes clusters in the cloud. With OKE, organizations can build dynamic containerized applications by incorporating Kubernetes with services running on their Oracle Cloud Infrastructure. We’ve partnered with Oracle so that you can use the Datadog Agent to get comprehensive visibility into your Kubernetes clusters on Oracle Cloud Infrastructure.
The recent public release of Cycle’s API has already seen all sorts of innovative uses, from automating the deployments of medical applications, to creating customized monitoring services to track specific performance metrics. Everything you can do in the portal can also be accomplished via the API — it’s actually the exact same API we used to build the portal!
AquaSec’s Daniel Sagi recently authored a blog post about DNS spoofing in Kubernetes. TLDR is that if you use default networking in Kubernetes you might be vulnerable to ARP spoofing which can allow pods to spoof (impersonate) the IP addresses of other pods. Since so much traffic is dialed via domain names rather than IPs, spoofing DNS can allow you to redirect lots of traffic inside the cluster for nefarious purposes.
Cycle’s API docs are live, and with it a whole new suite of tools to automate the management of containers across cloud providers. This is the same API that Cycle’s portal is built upon, meaning you have near full capability to do anything programmatically that you can do through the interface.
