  • Deploy Secure Spring Boot Microservices on Amazon EKS Using Terraform and Kubernetes

    The JHipster scaffolded sample application has a gateway application and two microservices. It uses Consul for service discovery and centralized configuration.

    Service Discovery: Microservices need to discover and communicate with each other dynamically. Service discovery tools like etcd, Consul, or Kubernetes built-in service discovery mechanisms help locate and connect to microservices running on different nodes within the infrastructure.
  • Replicating and Load Balancing Go Applications in Docker Containers with Consul and Fabio
    4 projects | /r/golang | 31 May 2023
    After some research and testing, I landed on using Consul and Fabio as the demo infrastructure. Of course, there is a myriad of other options to accomplish this task, but because of the low configuration and ease of use, I was impressed with this pairing. Both projects are mature and well-supported, and very flexible--just because you can run them with low configuration, doesn't mean you have to. I wanted to keep this demo constrained, but the exercise did get me excited about exploring things further: circuit breakers, traffic splitting, and more complex service meshes.

    The goal is to be able to use Consul SD configurations to allow for retrieving scrape targets from consul. Is this possible? Can anyone provide an example? Thank you!!

    The Consul collector is production ready! Consul by HashiCorp is a powerful and complex identity-based networking solution, which is not trivial to monitor. We were lucky to have the assistance of HashiCorp itself in this endeavor, which resulted in a monitoring solution of exceptional quality. Look for common blog posts and announcements in the coming weeks!

    Changed the service discovery to Consul, since this is the default in JHipster 8.

    In another effort to standardize development and operations, Lob has just wrapped up our container orchestration migration from Convox to HashiCorp’s Nomad, led by Senior Platform Engineer Elijah Voigt. In this new ecosystem, one feature available to us is Consul Service Mesh (a feature of Consul, which is part of our Lob Nomad stack).

  • How I use Devbox in my Elm projects
    15 projects | | 2 May 2024
    These projects use Caddy as my local development server, Dart Sass for converting my Sass files to CSS, elm, elm-format, elm-optimize-level-2, elm-review, elm-test (only in Calculator), ShellCheck to find bugs in my shell scripts, and Terser to mangle and compress JavaScript code.

    No, look at the associated unit test:

    If that test fails we could serve PHP source code instead of having it be evaluated, a major security flaw.

  • How to securely reverse-proxy ASP.NET Core web apps
    3 projects | | 4 Apr 2024
    However, it's very unlikely that .NET developers will directly expose their Kestrel-based web apps to the internet. Typically, we use other popular web servers like Nginx, Traefik, and Caddy to act as a reverse-proxy in front of Kestrel for various reasons:

    I think that recompiling with upgraded Go will not solve the issue. It seems Caddy imports `` and pins it to v0.22.0 which is vulnerable:
  • Show HN: Nano-web, a low latency one binary webserver designed for serving SPAs
    8 projects | | 25 Mar 2024
    Caddy [1] is a single binary. It is not minimal, but the size difference is barely noticeable.

    serve also comes to mind. If you have node installed, `npx serve .` does exactly that.

    There are a few go projects that fit your description, none of them very popular, probably because they end up being a 20-line wrapper around http frameworks just like this one.


  • I Deployed My Own Cute Lil’ Private Internet (a.k.a. VPC)
    8 projects | | 18 Mar 2024
    Each app’s front end is built with Qwik and uses Tailwind for styling. The server-side is powered by Qwik City (Qwik’s official meta-framework) and runs on Node.js hosted on a shared Linode VPS. The apps also use PM2 for process management and Caddy as a reverse proxy and SSL provisioner. The data is stored in a PostgreSQL database that also runs on a shared Linode VPS. The apps interact with the database using Drizzle, an Object-Relational Mapper (ORM) for JavaScript. The entire infrastructure for both apps is managed with Terraform using the Terraform Linode provider, which was new to me, but made provisioning and destroying infrastructure really fast and easy (once I learned how it all worked).
  • Automatic SSL Solution for SaaS/MicroSaaS Applications with Caddy, Node.js and Docker
    1 project | | 29 Feb 2024
    So I dug a little deeper and came across this gem: Caddy. Caddy is this fantastic, extensible, cross-platform, open-source web server that's written in Go. The best part? It comes with automatic HTTPS. It basically condenses all the work our scripts and manual maintenance were doing into just 4-5 lines of config. So, stick around and I'll walk you through how to set up an automatic SSL solution with Caddy, Docker and a Node.js server.

    One of the most heavily used Russian software projects on the internet but it's only marginally more modern than Apache httpd.
