50 Useful Kubernetes Tutorials for IT Professionals

Technologies like Docker have made it easier to continuously deploy applications across any number of host servers. They eliminate the need for having your own virtual machine because all the code and configuration settings you need to run your app is packaged into one container.

Google created Kubernetes to automate a number of tasks and processes involved in managing containerized apps. You can use Kubernetes to automatically deploy, scale, and decommission containerized applications. Of course, Kubernetes is not a silver bullet, and Kubernetes deployments have opened up a new set of infrastructure security concerns for DevOps teams. That’s why it’s important to be well versed in how to work with Kubernetes, as well as the tactics and solutions you can employ to create a more secure environment. For instance, Threat Stack now provides security and IT leaders transitioning to container-based infrastructure with the expertise and enhanced security visibility necessary to effectively manage the addition of container-based cloud environments through our Threat Stack Cloud Security Platform® and Threat Stack Cloud SecOps Program℠.

If you are planning to take a systematic approach to learning Kubernetes, then you should be on the lookout for quality tutorials. The good news is that a lot of resources are available online. There are also more structured courses that sometimes offer certification — if you’re willing to pay, that is. Read more “50 Useful Kubernetes Tutorials for IT Professionals”

Why Kubernetes is Not a Silver Bullet

Container adoption is on a meteoric rise. Gartner estimates that 50 percent of companies will use container technology by 2020, up from less than 20 percent in 2017. It’s not hard to see why — containers’ offer greater DevOps flexibility along with an optimized build/deployment pipeline.

The surge in container adoption is the driving force behind a new phenomenon in developer circles that we at Threat Stack lovingly refer to as “Kubernetes FOMO.” Eager to get on board with the most popular orchestration platform around, organizations are jumping on the Kubernetes bandwagon.

And why not? Kubernetes speeds container deployment and enables the management of multi-container clusters at scale. It allows for continuous integration and delivery; handles networking, service discovery, and storage; and has the ability to do all that in multi-cloud environments.  

Some would call Kubernetes a silver bullet in the world of container deployment and management, but that doesn’t mean it comes without security concerns. In this post, we’ll discuss a few things to watch out for if you’re considering a move to Kubernetes, as well as some tips on ensuring that your infrastructure remains secure during a transition.

3 Things to Know About Kubernetes Security

Gartner estimates that 50 percent of companies will use container technology by 2020, up from less than 20 percent in 2017. The operational benefits of containers, including optimized build times and more efficient use of infrastructure resources, have caused a surge in interest in container orchestration platforms like Kubernetes. At the same time, Kubernetes deployments have opened up a whole new set of infrastructure security concerns for Development and Operations teams.

For teams just getting started with Kubernetes deployments, here’s an overview of three things you need to know about securing your infrastructure from the outset. Read more “3 Things to Know About Kubernetes Security”
