kubectl enables system administrators to interact with Kubernetes using a well-designed command-line interface. The common interactions include running services, grabbing pod logs, or identifying nodes inside of a cluster. For most Kubernetes users, these interactions are second nature.

CoreOS builds open source software. Why build with open source? Because the problem to be solved is massive, and innovation is needed at the macro level. It is estimated:

Since the first enterprise technology systems became available, they have promised greater freedom, efficiency and productivity, yet each successive generation demanded considerable capital expenditure for proprietary software that made the option of changing vendors prohibitive. Despite the unquestionable promise of cloud computing, the landscape is beginning to look familiarly restrictive. Today at CoreOS Fest, we are showing how CoreOS Tectonic is focused on breaking this cycle of restriction, all via open source technologies.

Prometheus is a monitoring system and time series database expressly designed for the highly distributed, automated, and scalable modern cluster architectures orchestrated by systems like Kubernetes. Prometheus has an operational model and a query language tailored for distributed, dynamic environments.

CoreOS Fest, the distributed systems, containers and Kubernetes conference, is coming up on May 31 and June 1 in San Francisco. This two-day event is the only 2017 West Coast conference for those in the Kubernetes community (new and seasoned alike) to come together and share stories, and we want to make sure you are all planning to be there. Last year, the event was in Berlin, and for its third year CoreOS is bringing the conference back to San Francisco.

Kubectl is a familiar tool if you use Kubernetes, and it has a broad functionality that takes time to master; it can be a more powerful tool than many people expect. Great resources exist for working with the kubectl command line interface. This is a collection of tips and tricks that will allow you to expand your ability to work with kubectl. Be sure to take a look at the cheat sheet in the kubernetes.io docs section as well!

At the end of March we saw Kubernetes 1.6, the first release led by a non-Google employee (CoreOS’ own Dan Gillespie), released in upstream. Today we announce the release of CoreOS Tectonic 1.6.2.

The primary focus of this release, in addition to delivering the most current, upstream version of Kubernetes to Tectonic users, is to turn on a number of features that deliver enterprise Kubernetes.

The major updates that make up Tectonic 1.6.2 include:

While Kubernetes is ushering in a world where SSH is less necessary on a daily basis for deploying and managing applications, there are still instances when SSH is necessary for gathering statistics, debugging issues, and repairing configuration issues. So, while years from now there may not be a need to SSH and run one-off debugging sessions, the tools below are useful for quickly SSH'ing into machines in your Kubernetes cluster.

Bringing AWS Application Load Balancer support to Kubernetes with Ticketmaster

Teams running Kubernetes have long desired more than the "out of the box" cloud provider integration for load balancers. This is especially true on AWS, where provisioning a Classic Elastic Load Balancer (ELB) per service might not cut it (financially and functionally).

It’s easy to forget how new Kubernetes and containers are. Those of us who’ve already embraced them should remember we’re on the frontier. If you’re a regular reader of the CoreOS blog, you’re likely with us on that bleeding edge.

This post will be a little different than our usual. Its goal is to introduce Kubernetes to folks who aren’t on the frontier. That might be those in tech who work on the business side, or developers who have yet to make the leap into containers. To tell the tale, we’ll get a little help from everyone’s favorite frozen treat—ice cream.
