November Meetup - GitOps with Rancher Continuous Delivery

As the number of clusters under management increase, application owners and cluster operators need a programatic way to manage deploying to their clusters. Rancher Continuous Delivery allows an administrator to create groups of clusters and link them to Git repositories. This means an application owner only ever needs access to the Git repository and not the management cluster. Deployment manifests can be defined in Helm, Kustomize or K8s yaml files and can be tailored based on attributes of the target clusters.

JFrog ChartCenter: How to Include Helm Charts from Source

Learn how you can add your Helm chart to ChartCenter directly from its Git-stored source. ChartCenter will host your Helm repository for you to share it with the world. Until the release of Helm v3, you might have submitted your Helm chart to the official `stable` or `incubator` chart repository to share it with the community. But this Helm chart archive is no longer actively maintained, and is not accepting new charts. Now all Helm charts must be in a hosted repository elsewhere.

All That Developers Need Is a Browser (or How to Be More Productive by Having Less)

What would you say if I would tell you that you can be as productive with the cheapest laptop as with the one you already have? Would you believe me if I would say that there is no need for you to install an IDE, compilers, CLIs, Docker, and whatever else you might have on your laptop? How about having a full development environment created whenever you need it instead of dealing with virtual machines and whatever else might be fulfilling your development needs?

Mitigating Kubernetes Security Vulnerability when using ExternalIP Services (CVE-2020-8554)

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.
