Various policy engines for Kubernetes policies - Saiyam Pathak

Kubernetes configurations are complex to manage across developers and operators. External tools like Helm, Kustomize cannot ensure environment-specific configurations and admission controllers provide a way to do this. Now, various tools have evolved over time that helps solve this problem - OPA Gatekeeper, Kyverno, Kubewarden and jsPolicy. In this talk during ContainerDays 2021, Saiyam Pathak from Civo goes through the need for a policy engine and discusses how each of the tools help along with the differences between them and where these are headed to.

A CTO's View: Driving Continuous Alignment with Mattermost 6.0

ChatOps and Mobile Adoption: The Power of Teams Working Where They Are

The way we socialize, learn, shop, and receive care has changed drastically over the last 18 months. For many of us, perhaps one of the most drastic changes was the way we work. While work from home (WFH) was an option before the pandemic, NCCI states, “only 6% of the employed worked primarily from home and about three-quarters of workers had never worked from home.” Fast forward to 2021, and according to NorthOne, here’s how much things have changed.

Enhance the security of your open-source applications and share feedback

Are you spending time on high-impact, high-value activities, or are you constantly derailed by maintenance, support, and deployment challenges? Does your organisation consume open-source software that needs security patching? Where do you get the security updates from, and how do you track what’s available? Are you responsible for vulnerability management, compliance, and long term maintenance of the software running on top of Ubuntu in your organisation?

LMA 2: Reimaginging observability with MicroK8s and Grafana, Prometheus and Grafana Loki

Juju re-imagines the world of operating software securely, reliably, and at scale. Juju realizes the promise of model-driven operations. Excellent observability is undeniably a key ingredient for operating software well, which is why the Charmed Operator ecosystem has long provided operators the ability to run a variety of open source monitoring software. We collectively refer to these operators as the Logs, Metrics, and Alerts (LMA) stack.

Monitor NS1 with Datadog

NS1 is an intelligent DNS and traffic management platform that helps optimize the performance of your network infrastructure and speed application delivery to your end users. Since even a small increase in service latency can lead to churn and revenue loss, it’s critical to remove any inefficiencies embedded in basic network functions. NS1 helps ensure high performance for name resolution and routing through support for the edns0-client-subnet (ECS) DNS extension and for Filter Chain technology.

How Debian Cron Handles DST Transitions

When the Daylight saving time starts, and the computer’s clock jumps forward, what does cron do? If the clock jumps from 1AM to 2AM, and there is a job scheduled for 1:30AM, will cron run this job? If yes, when? Likewise, when the Daylight saving time ends, and the clock jumps backward, will cron possibly run the same scheduled job twice? Let’s look at what “man cron” says.

Forecasting Kubernetes Costs

The benefits of containerizing workloads are numerous and proven. But, during infrastructure transformations, organizations are experiencing common, consistent challenges that interfere with accurately forecasting the costs for hosting workloads in Kubernetes. Planning the proper reservations for CPU and memory before migrating to containers is a persistent issue Densify observes across our customers.

Deploy Iron Bank-Approved Artifactory/Xray on AWS GovCloud and RKE2

With Artifactory and Xray now included in the U.S. Department of Defense’s Iron Bank container repository, we’re eager to help you benefit from this accreditation. Today, we’ll explain how to deploy these hardened JFrog images on AWS GovCloud using Rancher Kubernetes Edition (RKE2.)
