In this guide, I’ll walk through setting up a site-to-site VPN between Google Cloud and a CentOS 9 VM hosted on DigitalOcean. We’ll use strongSwan to establish the IPsec tunnel, and the BIRD Internet Routing Daemon to peer with a Google Cloud Router and exchange routes dynamically using BGP.
Looking for a simple way to serve files over HTTP? In this guide, I'll walk through setting up a file server using Caddy, a modern web server written in Go. With minimal configuration, built-in directory browsing, and optional basic authentication, Caddy makes it easy to share files.
Secure your application with OAuth2 Proxy and Microsoft Entra ID. In this post, I’ll walk you through configuring OAuth2 Proxy to authenticate users via Entra ID, both as a reverse proxy in front of your application and as a forward authentication provider using Traefik.
Automating infrastructure deployments using Terraform and GitHub Actions is a common practice. In this post, we’ll walk through setting up a Terraform workflow in GitHub that runs a Terraform Plan and sends a Slack notification with the diff whenever there are changes detected.
In this post, we’ll walk through setting up Traefik as an application proxy with Docker Compose, including automatic provisioning of Let's Encrypt TLS certificates via HTTP and DNS validation.
If you prefer keeping your documentation in Git, love writing in Markdown, but need to publish it in Confluence, Confluence Updater is the perfect solution.

If you use GitHub, you likely rely on an SSH key to clone repositories and sign commits. However, when working with a GitHub Enterprise-managed account, you must set up a separate SSH key because the same key cannot be shared across different accounts. This guide will show you how to create and configure a new SSH key for a second account. Additionally, you'll learn how to configure Git to automatically apply specific settings for repositories that match certain URL patterns.
Setting up authentication for pushing images to Google Artifact Registry from a Github pipeline is usually done by creating a static, forever valid, credential file for at service account, which will probably never be rotated. An alternative to that is to use Workload Identity Federation to exchange a Github issued JWT token with a Google token and use that for authentication.
When creating a good bash script for others to use, it's important to create a good user experience. Creating good usage arguments makes all the difference and really makes your script look professional instead of just a list of commands bunced together in a file.
With Mirrord you can intercept traffic for your pods in your Kubernetes cluster, which allows you to develop your application locally as if it was deployed in your cluster. Utilizing the pods network, environment or even the filesystem. In this post I will be writing some examples that I personally use.
