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.

11. Getting Started with Kubernetes on AWS
Some tutorials are great, but you won’t learn anything if you’re easily bored with what you are watching. It could be because of the speaker, being a tad too formal. Or it could be because you are looking for particular information, and skipping ahead won’t be helpful because you simply don’t know where to skip to and you might end up missing the exact part you are looking for.
The good news is that this is a series of videos that won’t give you any of these headaches. If you are looking for information on Kubernetes and AWS, then you should check out Jeffrey Taylor’s “Getting Started with Kubernetes on AWS” series.
Taylor divided his Web cast into nine different parts:
- Part 1. Kops and Kubectl
- Part 2. Kops and Route53
- Part 3. More Kops and Route53
- Part 4. Hapi.js Web server
- Part 5. Creating a Dockerfile
- Part 6. Running a container locally
- Part 7. Pushing to ECR
- Part 8. Deploying a pod
- Part 9. Deployed!

It also introduces logging using Kibana, Fluetd, LogTrail, using Auth0, RBAC, Helm, Spinnaker, kubefed, Linkerd, and Prometheus. Support files and course materials are provided.
There are occasions when you would prefer to build your own Kubernetes clusters. However, you might not have any idea what tools and installers to use. WeaveWorks has developed this tutorial for those who want to build custom clusters. It begins with the hard way to do things, and then launches into alternatives for installing Kubernetes. It also includes a discussion on Terraform and Ansible.
The tutorial discusses different installers you can use, including kops, Kubeadm, and kubicorn. It outlines the pros and cons of every installer and helps you decide on your own. You will also learn how to use these tools with a step-by-step guide, and will be given links to other useful resources.

Operators automate tasks related to Kubernetes, thus enabling you to focus more on developing your applications. However, these operators are not that easy to create, and you would need to be an expert on how Kubernetes works in order to build and implement them.
In this tutorial, Red Hat’s CoreOS CTO Brandon Philips talks about how to create your own operators so you have more time to work on your applications.
While most courses and tutorials focus on the basics, best practices, and how to use Kubernetes, “Anatomy of a Production Kubernetes Outage” will tell you what to expect in the event of an outage.
This talk was given by Oliver Beattie, Head of Engineering, Monzo Bank, based on their company’s experience. It discusses the causes of the Kubernete’s outage that affected Monzo, as well as how it affected them. It also provides insights on how to design and manage Kubernetes from their experience.

One benefit of working with Kubernetes is that there is a community you can turn to if you need help with deployment. This same community has been writing and developing new features over time. These new features are being deployed as external controllers.
In this tutorial, Alena Prokharchyk ( Principal Software Engineer, Rancher Labs, Inc.) tells you more about writing these extensions using custom resource definition. She takes you through the complete lifecycle for CRD resources – from defining clients, schema, and types to using informers to control resource.

Prokharchyk also speaks about the challenges of CRD management that you should expect to encounter, as well as suggested solutions for each.
Morgan Bauer is an open source contributor at IBM, while Sriniva Brahmaroutu works as a software engineer for the same company. In this talk, Bauer and Brahmaroutu delve into custom resource definition. CRD has long been regarded as a good way to extend the capabilities of Kubernetes. You will also learn how to manage custom resources and controllers. The two share their experiences in leader election, the difference between clustered CRDs and namespaced CRDs, and how to manage and respond to unexpected events from APIServers, among other things.
And Even More . . .
As you can see from this post, there’s a huge array of Kubernetes materials that you can watch, read, and join. A lot of these are freely available on the Web, and a number are taught by some of the most renowned experts in the technology.
