Caddy VS caddy-docker-proxy

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: https://github.com/caddyserver/caddy/blob/c6eb186064091c79f4...

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

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 `golang.org/x/net/http2` and pins it to v0.22.0 which is vulnerable: https://github.com/caddyserver/caddy/issues/6219#issuecommen....

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.

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).

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.

Let's use Caddy which can act as reverse-proxy with automatic HTTPS coverage.

Even if it may be simple, it doesn't handle edge cases such as https://github.com/caddyserver/caddy/issues/1632

I personally would make the trade off of taking on more complexity so that I can have extra compatibility.

One of the most heavily used Russian software projects on the internet https://www.nginx.com/blog/do-svidaniya-igor-thank-you-for-n... but it's only marginally more modern than Apache httpd.

In light of recently announced nginx memory-safety vulnerabilities I'd suggest migrating to Caddy https://caddyserver.com/

Sticky sessions are supported: https://caddyserver.com/docs/caddyfile/directives/reverse_pr..., and yes it's pluggable so you could write your own LB policy. Very easy, just copy the code from Caddy's source to write your own plugin. Let us know if you need help.

Also yes, Caddy does service discovery if you use https://github.com/lucaslorentz/caddy-docker-proxy, configuration via Docker labels. Or you can use dynamic upstreams (built-in) https://caddyserver.com/docs/caddyfile/directives/reverse_pr... to use A/AAAA or SRV DNS records to load your list of upstreams.

Caddy via Caddy Docker Proxy (network).

https://github.com/lucaslorentz/caddy-docker-proxy

It handles the routing to multiple dockerized projects on one server, by scanning docker compose files for labels and automatically setting up the required caddy configuration.

My go to is always this instead:

https://github.com/lucaslorentz/caddy-docker-proxy

Single label to a docker container and with correct DNS you’ll have an automatically managed certificate right away.

I have had a great experience with using this: https://github.com/lucaslorentz/caddy-docker-proxy

It combines caddy with docker-compose labels, making it super easy to spin up new projects that can immediately be exposed.

If you want a slightly heavier but more robust solution, caddy-docker-proxy[0] is a plugin that listens to the Docker socket and automatically updates the Caddy configuration based on Docker labels you add to containers.

I.e. it makes Caddy act a bit more like Traefik. Most of the time, you'll just add the label `caddy.reverse_proxy={{upstreams http 8080}}` to your containers and the plugin will regenerate Caddy's configuration whenever the container is modified.

I disagree, Caddy works great in Docker. See https://caddyserver.com/docs/running#docker-compose, and CDP is a project that autoconfigures Caddy from labels https://github.com/lucaslorentz/caddy-docker-proxy. Regarding plugins, it's super simple to write a Dockerfile to add plugins, we ship a builder image variant that can be used to compile in any plugins you want.

This way, Caddy will buffer the request and give 30 seconds for your new service to get online when you're deploying a new version.

Ideally, during deployment of a new version the new version should go live and healthy before caddy starts using it (and kills the old container). I've looked at https://github.com/Wowu/docker-rollout and https://github.com/lucaslorentz/caddy-docker-proxy but haven't had time to prioritize it yet.

Docker labels support is available via a plugin https://github.com/lucaslorentz/caddy-docker-proxy
