urbackup-client-docker VS traefik

For backups I use UrBackup, and with the UrBackup Client container, I can back up each application's persistent volumes. I run it in Docker for now, and store backups on a BTRFS Zvol in my ZFS array. Though technically it's not totally safe to backup databases this way, I have not run into many issues going this. Restoring or migrating is as simple as spinning up my helm chart on the new server (with only the client and its Persistent Volume Claims active), hitting restore, and then upgrading the deployment with the actual databases and services.

Pronounced "traffic", Traefik is a modern HTTP reverse proxy and load balancer aimed at making deploying microservices easier. It integrates with your existing infrastructure components such as Docker, Kubernetes, and others, and configures itself automatically and dynamically. The latest version adds lots of new options and enhancements such as adding healthcheck options, support for custom headers, and more. Read the migration guide on how to update to the latest version which is now required due to breaking changes.

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:

Not as good though. Case in point: https://github.com/traefik/traefik/issues/5472#issuecomment-... (that's just from this morning)

I'm speak objectively here. Of course, any built-in auto HTTPS that works (more or less) is better than none. Traefik uses an ACME library that was originally written for Caddy. After the original author left that project, Traefik team started maintaining it. Caddy's users' requirements exceeded what the library was capable of, but unfortunately there was friction in getting it to achieve our requirements. So I ended up writing a new ACME client library in Go and, together with upgrades in CertMagic (Caddy's auto-TLS lib), Caddy has the more flexible, robust, and capable auto-HTTPS functionality.

That is to say, not all auto-HTTPS functionalities are the same.

We'll use Traefik, an open source cloud native gateway that can plug into a Kubernetes cluster. It has the concept of "middleware" that can process API requests before passing them through to a backend. We can configuring a rate limit for all of our API endpoints by matching on the request path:

I did the same question here and here

Sadly there is currently no way of doing so. https://github.com/traefik/traefik/issues/6999

Traefik is another widely used system that has automatic configuration and offers support for more things like swarm/kubernetes/etc.
