Introducing Jetstack Flightdeck

We are pleased to announce Flightdeck, our online Jetstack Subscription portal. In this first release, customer teams can now run Operational Wargaming exercises from their browsers - self-paced and on-demand.

If you’ve attended one of our in-person Operational Wargaming workshops, you’ll be familiar with the format. We provision Kubernetes clusters and then break them, in order to simulate production issues and cluster failures.

With Flightdeck, these same exercises are now available on-demand, so operations teams can become familiar with troubleshooting cluster failures and drill themselves on effective response and resolution.

Introducing Jetstack's Kubernetes for Application Developers Course

Introduction Our Kubernetes training programme forms a considerable part of our services at Jetstack. In 2017 alone we trained more than 1,000 engineers from over 50 different companies, and so far in 2018 we have already delivered over 60 courses. We are constantly making an effort to ensure that our course content is refined and up-to-date, and that it reflects both the real-world experience of our engineers and also the evolving Kubernetes ecosystem.

Istio at 1.0 - Why should you care?

Businesses operating at scale face several challenges. Not only must many applications be maintained - running in different environments and built in different languages - but application behavior should be monitored closely, whilst adhering to strict security policies. There is a lot to juggle.

A Conversation with Jetstack's Head of Growth

Simon, our Head of Growth, details his experience as part of the growing commercial team at Jetstack. What are your main duties as Head of Growth at Jetstack? ‘Head of Growth’ is a relatively new title that has been more recently adopted by fast growing tech companies. It can mean different things to different people but the role is usually focused on scaling a business, product or customers. In my case, at Jetstack, I lead the business development side of the organisation which includes our Sales & Go-to-Market, Marketing and PR functions.

Adventures of the Kubernetes Vacuum Robots

Have you ever wondered how to run kubelet on a vacuum robot?

Our guess is, you haven’t - and nor have many other people. However, this didn’t stop Christian’s talk from attracting a large following at KubeCon Europe 2018, nor did it deter some curious conference goers from attempting to win a robot of their own!

Cert-manager: native x509 certificate management for Kubernetes

Those of you who closely follow Jetstack’s open source projects may have already noticed that our new certificate management tool, cert-manager, has been available for some time now. In fact, we now have over 1,000 stars on GitHub!

Cert-manager is a general purpose x509 certificate management tool for Kubernetes. In today’s modern web, securing application traffic is critical. cert-manager aims to simplify management, issuance and renewal of certificates within your organisation.

Introducing Jetstack Subscription

We are delighted to announce Jetstack Subscription, comprising tried-and-tested Kubernetes Reference Architecture, the highest quality training, and continuous support for organisations adopting Kubernetes.

As a leading Kubernetes company in Europe, Jetstack Subscription has been designed and refined to give organisations the confidence to take Kubernetes to production environments.

Kubernetes 1.10: Hidden Gems

Coming up to four years since its initial launch, Kubernetes is now at version 1.10. Congratulations to the many contributors and the release team on another excellent release!

At Jetstack, we push Kubernetes to its limits, whether engaging with customers on their own K8s projects, training K8s users of all levels, or contributing our open source developments to the K8s community. We follow the project day-to-day, and track its development closely.

New Jetstackers in 2018

Introduction As ever, the Jetstack team are incredibly busy. Recent months have seen back-to-back Kubernetes consulting, training and open source development, as more and more companies adopt Kubernetes in order to meet the demands of their business. It has to be said that at Jetstack we are scaling to meet the demands of our business: Just 3 months into 2018, and we have already grown by 3 members! We are delighted to welcome to our team Matt (yes, another!

Kubernetes Training with Jetstack

This blog post provides an insight into how we run our Kubernetes workshops as we prepare for even more from Jetstack training in 2018. Introduction In 2017, Jetstack ran more than 25 Kubernetes in Practice workshops: We trained engineers from over 80 different companies in London and across Europe, and had a great time doing so! 2018 promises to be an even busier year for Jetstack training, with several dates already in the diary for our first and second series of Beginner and Intermediate workshops.

The Kubernetes Market in 2018

Not long ago, I overheard the Jetstack team chatting about recent changes in the market and the increasingly widespread adoption of Kubernetes. Only when I reflected to write this did I realise that we have been saying the same thing every few months for the past year. Indeed, the Kubernetes market shows no sign of slowing down. Jetstack alone has tripled in size as we scale to cater to demand, KubeCon has gone from a couple of hundred in a small room to 4000 in a vast conference centre, and recent announcements have seen millions of dollars pour into the space as companies like Cisco and VMWare announce strategic investments.

What's New in Navigator?

Navigator is a Kubernetes extension for managing distributed databases. In this post we’ll tell you about all the improvements we’ve made since we unveiled it last year, including: experimental support for Apache Cassandra clusters, improved support for Elasticsearch clusters, and a Helm chart for easy installation! We’ll also give you an overview of the Navigator roadmap for 2018.

Kubernetes 1.8: Hidden Gems - Volume Snapshotting

In this Hidden Gems blog post, Luke looks at the new volume snapshotting functionality in Kubernetes and how cluster administrators can use this feature to take and restore snapshots of their data. Introduction In Kubernetes 1.8, volume snapshotting has been released as a prototype. It is external to core Kubernetes whilst it is in the prototype phase, but you can find the project under the snapshot subdirectory of the kubernetes-incubator/external-storage repository.

A Day in the Life of a Jetstack Solutions Engineer

Solutions Engineer Luke provides an insight into what it’s like to work on Kubernetes projects with Jetstack. What made you want to work for Jetstack? I wanted to work for Jetstack because they offered me the opportunity to work on a variety of different projects, both with private clients and in open source. On one hand, I provide consultation for customers about Kubernetes best practices, and run workshops with Google to teach those who are relatively new to Kubernetes about the various tools available within the software.

Introducing Tarmak - the toolkit for Kubernetes cluster provisioning and management

We are proud to introduce Tarmak, an open source toolkit for Kubernetes cluster lifecycle management that focuses on best practice cluster security, management and operation. It has been built from the ground-up to be cloud provider-agnostic and provides a means for consistent and reliable cluster deployment and management, across clouds and on-premises environments.

Kubernetes 1.8: Hidden Gems - The Resource Metrics API, the Custom Metrics API and HPA v2

In the coming weeks we will be releasing a series of blog posts called Kubernetes 1.8: Hidden Gems, accenting some of the less obvious but wonderful features in the latest Kubernetes release. In this week’s gem, Luke looks at some of the main components in the core metrics and monitoring pipelines and in particular how they can be used to scale Kubernetes workloads. Introduction One of the features that makes Kubernetes so powerful is its extensibility.

Couchbase on OpenShift and Kubernetes

Jetstack are pleased to open source a proof-of-concept sidecar for deployment of managed Couchbase clusters on OpenShift. The project is the product of a close engineering collaboration with Couchbase, Red Hat and Amadeus, and a demo was presented at the recent Red Hat Summit in Boston, MA.

This project provides a sidecar container that can be used alongside official Couchbase images to provide a scalable and flexible Couchbase deployment for OpenShift and Kubernetes. The sidecars manage cluster lifecycle, including registering new nodes into the Couchbase cluster, automatically triggering cluster rebalances, and handling migration of data given a scale-down or node failure event.

Introducing Navigator

Today we are proud to introduce Navigator, a centralised controller for managing the lifecycle of complex distributed applications. It intends to be the central control point for creating, updating, managing and monitoring stateful databases and services with Kubernetes.

Navigator is open source and extensible from day one. We launch today with support for Elasticsearch in alpha, with Couchbase support soon to land in the next few weeks, and more planned.

Kubernetes 1.3: Hidden Gems

With over 5000 commits and almost 350 contributors from the community and across industry, Kubernetes is now at version 1.3 and launched last week.

It is nearly two years ago that Kubernetes first launched. The scale of community engagement and innovation in the project has been staggering, with individuals collaborating alongside industry leaders (Google, RedHat et al) to push forward and bring production-grade container cluster management to all. This blog will investigate 1.3 and some of the hidden gems found in it.

Automated certificate provisioning in Kubernetes using kube-lego

In this blog post, we are pleased to introduce Kube-Lego, an open source tool for automated Let’s Encrypt TLS-enabled web services running in Kubernetes.

TLS has become increasingly important for production deployment of web services. This has been driven by revelations of surveillance post-Snowden, as well as the fact that Google now favours secure HTTPS sites in search result rankings.

An important step towards increased adoption of TLS has been the availability of Let’s Encrypt. It provides an easy, free-of-charge way to obtain certificates. Certificates are limited to a 90-day lifetime and so the free certificate authority (CA) encourages full automation for ease-of-use. At the time of writing, Let’s Encrypt has approaching 3.5 million unexpired certificates so adoption has certainly been strong.

Kube-Lego automates the process in Kubernetes by watching ingress resources and automatically requesting missing or expired TLS certificates from Let’s Encrypt.

High Availability and Services with Kubernetes

In our previous blog, Getting Started with a Local Deployment, we deployed an Nginx pod to a standalone (single-node) Kubernetes cluster. This pod was bound to a specified node. If the pod were to fail unexpectedly, Kubernetes (specifically, the Kubelet service) would restart the pod. By default, pods have an ‘Always’ restart policy, but only to the node that it is first bound; it will not be rebound to another node. This means of course that if the node fails then pods will not be rescheduled elsewhere.

Kubernetes: Getting Started With a Local Deployment

In Part 1 of this series of blogs, we introduced Kubernetes, an open source container management system from Google, based on operational systems that run over 2 billion containers a week. Kubernetes will very soon be production-ready with the 1.0 release scheduled for this month. In this second part, we will get hands-on, setup a local cluster and deploy a Nginx web server.

Kubernetes: Are you Ready to Manage your Infrastructure like Google?

Google’s Kubernetes open source project for container management has just recently celebrated its first birthday. In its first year, it has attracted massive community and enterprise interest. The numbers speak for themselves: almost 400 contributors from across industry; over 8000 stars and 12000+ commits on Github. And many will have heard it mentioned in almost every other conversation at recent container meetups and industry conferences – no doubt with various different pronunciations!
