Have you ever needed to turn on audit logs for the Kubernetes cluster bundled with Docker Desktop and wasn't sure how? Well, here's how!

While attempting to build a multi-tenant Kubernetes platform, I decided to use Karpenter to help create node pools for each tenant. Here's how we made each pool and forced tenants into the pool.

At Virginia Tech, I've been leading an effort to build a multi-tenant platform, currently on top of Kubernetes. But, there are a lot of things needed to pull this off. We'll dive into some of those in this post.

Karpenter is a new auto-scaling component from AWS and its docs are still growing. Here's how to deploy it using Terraform.

It's often tempting to use process.env in your frontend code. But, that means you either have to run Node in all environments or need to build the app for each location. How can we build once, deploy anywhere? In this post, we'll talk about externalizing our configuration.

Compose has slowly been adding support for additional backends, including an experimental k8s backend. I've been doing some digging to figure out how to support GitOps workflows, yet hook into the Docker Compose tooling.

When building a multi-tenant platform, you have to think about creating proper isolation between tenants. For VT's platform, Gatekeeper and OPA serves a critical role.

We were invited to present at Flux's KubeCon booth about some of the things we're doing with Flux that helps support our multi-tenant platform.

At DockerCon's first virtual conference, I had the opportunity to speak about Docker Compose! Here are my slides and extra resources. Enjoy!

Feeling overwhelmed while getting started with containers? Have you been tasked to figure out how to train everyone back at your organization? There's just so much to learn and teach! In this talk, we’ll start with a tiny bit of history to motivate the "why" and quickly move into the "what" by explaining what container and images actually are (they're not just magical black boxes!). We'll talk about how volumes help with data persistence and include an overview of Docker Compose and even orchestration. There will be plenty of live demos and fun!

Developing applications is tough. Especially in the ever-changing environments. We have local development. QA validation. Pre-prod/staging. Production. But, how do we ensure our applications work the same everywhere? While containers help out, they aren't the only thing to keep in mind. The folks at Heroku, in 2011, published "The Twelve-Factor App", which has become the standard for building cloud-native applications.
