Red Hat’s CoreOS Launches a New Toolkit for Managing Kubernetes Applications

CoreOS, the Linux distribution and container management startup Red Hat acquired for $250 million earlier this year, today announced the Operator Framework, a new open source toolkit for managing Kubernetes clusters. CoreOS  first talked about operators in 2016. The general idea here is to encode...

Cloud-Native Security Patching with DevOps Best Practices

In today’s world, the basic unit of deployment is a container image. Once you build a container image, it can’t be changed; if you want to update the image you need to rebuild a new version. When you start a container running, it’s instantiated from a container image, with the file system starting...

This month on Linux.com, we published several cloud-related articles to help clarify a few underlying ideas as well as examine specific implementations.

Cloud Computing in Focus: Serverless, Microservices, KubeCon + CloudNativeCon, and More

Cloud computing concepts can seem as nebulous as clouds themselves, but in April, we published several cloud-related articles to help clarify a few underlying ideas and look at some specific implementations. This month, Swapnil Bhartiya tackled the subject of serverless computing with There’s a...

Implementing Advanced Scheduling Techniques with Kubernetes

One of the advantages of using an advanced container orchestration tool like Kubernetes is the flexible scheduler. This provides a wide range of options for users to specify conditions for assigning pods to particular worker nodes that satisfy a condition, and not just based on available resources...

Data Protection for Containers: Part I, Backup

 How do you ensure data is properly backed up and recoverable according to current policies on a Kubernetes cluster? Traditional agent-based backup software won’t work natively with a container orchestrator such as Kubernetes. A Persistent Volume (PV) may be attached to any host at any given time...

Kubernetes StatefulSets gives you a set of resources to deal with stateful containers, such as: volumes and stable network ids; learn more in this preview from KubeCon + CloudNativeCon.

Extending Kubernetes API for Complex Stateful Applications using Operator

Conventional wisdom says you can’t run a database in a container because “Containers are stateless!” or “Databases are pointless without state!” However, this is not true any longer. We’ve been missing the right technology to support database running in a container. Then came Kubernetes 1.5, which...

The Future of Kubernetes Is Serverless

As we move forward, it’s becoming increasingly clear (to me at least) that the future will be containerized and those containers will run on serverless infrastructure. In this context, then, the obvious question is: “What becomes of orchestration in this serverless future?” Kubernetes is a...

Kubernetes
Learn about the new Kubernetes Cluster API in this preview of KubeCon + CloudNative, coming up May 2-4 in Copenhagen.

Extending the Kubernetes Cluster API

One major downside for developers is that Kubernetes has no native functionality to manage its nodes or other clusters. As a consequence, operations must get involved every time a new cluster or worker node is needed. Of course, several ways exist to create a cluster and also to create a new worker...

Helm
Learn how to run and test your code on a production-like environment with Kubernetes and Helm.

Put Wind into your Deployments with Kubernetes and Helm

I’m a Software Engineer. Every day, I come into work and write code. That’s what I’m paid to do. As I write my code, I need to be confident that it’s of the highest quality. I can test it locally, but anyone who’s ever heard the words, “...but it works on my machine,” knows that’s not enough. There...
