In a previous post, we explained the concept of configuration management and presented three of the most popular tools: Chef, Puppet, and Ansible. We also briefly explored the impact that containerization is having on configuration management, and how the two can be used in combination. This article takes a more in-depth look at this relationship by presenting different techniques for using Chef, Puppet, and Ansible to deploy and manage a Kubernetes cluster.

Gatsby is currently generating a ton of buzz as the new hot thing for generating static sites. This has lead to a number of frequent questions like: A static…what now? How is GraphQL involved? Do I need to set up a GraphQL server? What if I’m not a great React developer, really more of a bad React developer?

When you are using Rancher to manage your Kubernetes clusters, at some point you will encounter the terms Rancher, RKE, and custom cluster. If you are new to Rancher, it can be difficult to understand the difference between and purpose of each of these concepts. In this post, I will go over what each component is used for and how they are used together in parts of the system.

After closing a $20 million Series A round, Mattermost is skyrocketing in popularity as a secure, open source Slack alternative for enterprise DevOps and IT. High-trust teams are adopting it for messaging to overcome some of the biggest collaboration challenges today.

We are excited about Calico v3.5 release. This release provides more control and allows much finer-grained dynamic IP management vs the static allocation of a fixed set of addresses to each node in native Kubernetes. Here are the details.

I’ve been working on creating AWS Cognito User Pools in CloudFormation, and thought this would be a good time to share some of what I’ve learned.

Etcd is an open-source distributed key-value store created by the CoreOS team, now managed by the Cloud Native Computing Foundation. It is pronounced “et-cee-dee”, making reference to distributing the Unix “/etc” directory, where most global configuration files live, across multiple machines. It serves as the backbone of many distributed systems, providing a reliable way for storing data across a cluster of servers.

2018 is behind us and first of all we would like to thank all of our users, community members and customers for supporting us and making 2018 a successful year. In this post we would like to have a look at the various things we have released and important milestones we have reached in 2018.

Kubernetes is a fantastic tool for building large containerised software systems in a manner that is both resilient and scalable. But the architecture and design of Kubernetes has evolved over time, and there are some areas that could do with tweaking or rethinking. This post digs into some issues related to how image tags are handled in Kubernetes and how they are treated differently in plain Docker.

One of the biggest software development shifts of the past decade has been the emergence of the DevOps movement. There is a growing demand for DevOps Engineers, and organizations that have embraced DevOps practices are becoming more efficient in iterating through service delivery.
