The mechanism for interacting with Kubernetes on a daily basis is typically through a command line tool called kubectl. kubectl is primarily used to communicate with Kubernetes API servers to create, update, delete workloads within Kubernetes.

Secure access to your own private registry helps control who has access to your images. Compared to usage-based services such as Docker Hub and Quay, a Cycle hosted private registry only consumes the resources you give it access to, yielding a more cost-effective deployment. Let’s take a look at how simple it is to deploy a private Docker registry on Cycle.

DevOps is a very data-driven practice.

Deploying a basic Serverless application has been made easy with the abundance of frameworks out there. If you’re part of a small team or working on a relatively simple project, setting up a basic serverless CICD process is also pretty straightforward, since there is plenty of information on the subject. But when a Serverless application grows it can get very complex very fast.

Have you ever been confused about the different ways to handle missing data in the Ruby language? I know I have, and I’m sure I’m not alone in that.
