Since the revolutionization of the concept by Docker in 2013, containers have become a mainstay in application development. Their speed and resource efficiency make them ideal for a DevOps environment as they allow developers to run software faster and more reliably, no matter where it is deployed. With containerization, it’s possible to move and scale several applications across clouds and data centers. However, this scalability can eventually become an operational challenge.

Kubernetes — a popular open source container orchestration system — enables you to easily deploy, monitor, and scale cloud-native application workloads in both private and public cloud environments. In other words, Kubernetes does the hard work of managing containerized applications, giving you more time to spend building it.

While Kubernetes is a very powerful and comprehensive application, it can also be very complicated and confusing to new users. Thankfully, the community is great at pulling together to try to tame the Kubernetes beasts, and as more users join the platform, more handy tools to help you manage your cluster are developed. Kubernetes Resources range from everyday helper tools to development tools to troubleshooting tools, and in this article we’ll discuss fifteen of the best ones.

In October 2020 we released the community-driven roadmap for 2021. It's time to revisit and see all the things we have completed from the list! I am very proud to say that at Civo we have taken the community suggestions and implemented most of them during the launch on May 4th 2021. Let's dive into each of the features listed in the original blog post and see where we are with the 2021 Civo Roadmap.

The CVE-2021-25737 low-level vulnerability has been found in Kubernetes kube-apiserver where an authorized user could redirect pod traffic to private networks on a Node. The kube-apiserver affected are: By exploiting the vulnerability, adversaries could be able to redirect pod traffic even though Kubernetes already prevents creation of Endpoint IPs in the localhost or link-local range.

In its mission to simplify building and running cloud-native applications for users, Amazon has announced the GA of AWS App Runner, a new purpose-built container application service. With security top of mind for most organizations shifting to the cloud, Sysdig has collaborated with AWS to enable threat detection for the new platform.

The Atlanta Startup Podcast is the briefing room for the innovation ecosystem, featuring the investors, founders and activators creating the fastest emerging venture capital ecosystem in the country. Ken Ahrens, founder and CEO of Speedscale sits down with Valor Investor, William Leonard in this episode.

Nobody wants to deal with annoying neighbors. Whether it’s the neighbor who always knows everyone’s business or the one who turns up their music late at night, both types of neighbors can have a negative impact on your living environment and daily life. Obnoxious neighbors aren't exclusive to just your physical living space, but in the public cloud where there are multiple Kubernetes clusters (EKS, AKS, or GKE) and multiple users (or tenants) with the need for cluster access.

When Kubernetes launches and schedules workloads in your cluster, such as during an update or scaling event, you can expect to see short-lived spikes in the number of Pending pods. As long as your cluster has sufficient resources, Pending pods usually transition to Running status on their own as the Kubernetes scheduler assigns them to suitable nodes. However, in some scenarios, Pending pods will fail to get scheduled until you fix the underlying problem.
