Kubernetes: Tackling Resource Consumption

This is the third of a series of three articles focusing on Kubernetes security: the outside attack, the inside attack, and dealing with resource consumption or noisy neighbors. A concern for many administrators setting up a multi-tenant Kubernetes cluster is how to prevent a co-tenant from becoming a “noisy neighbor,” one who monopolizes CPU, memory, storage and other resources.

Manual Rotation of Certificates in Rancher Kubernetes Clusters

Kubernetes clusters use multiple certificates to provide both encryption of traffic to the Kubernetes components as well as authentication of these requests. These certificates are auto-generated for clusters launched by Rancher and also clusters launched by the Rancher Kubernetes Engine (RKE) CLI.

Kubernetes Master Class: How to Secure Production Kubernetes and Service Mesh Workloads on Rancher

As more container deployments move into production there will be an increasing level of attacks on application containers and the orchestration tools to manage them. The success of Kubernetes has been a major enabler for the “service mesh” concept to become a reality, as a “sidecar” container is the ideal form-factor for service mesh functions to be placed together with the service itself. The important thing to remember is that, although a service mesh has security features, it is NOT a security solution. It is not designed to provide the type of network, endpoint and host security required for defense in depth.

Kubernetes Master Class: Bringing Istio to Production

We all have gone through the introductory talks about Istio, but there is some confusion on how you can bring Istio in to a full production environment. In this master class, we will help you understand this journey of bringing Istio into a production environment and how it differs from your testing environments.

How To Manage Kubernetes with Kubectl

The mechanism for interacting with Kubernetes on a daily basis is typically through a command line tool called kubectl. kubectl is primarily used to communicate with Kubernetes API servers to create, update, delete workloads within Kubernetes. The objective of this tutorial is to provide an overview of some of the common commands that you can utilise, as well as provide a good starting point in managing Kubernetes.

Introducing Rio - Containers at Their Best

Today I’m excited to announce a new Rancher Labs project called Rio. Rio is a MicroPaaS that can be layered on any standard Kubernetes cluster. Consisting of a few Kubernetes custom resources and a CLI to enhance the user experience, users can easily deploy services to Kubernetes and automatically get continuous delivery, DNS, HTTPS, routing, monitoring, autoscaling, canary deployments, git-triggered builds, and much more.
