I replaced my haproxy setup with Traefik and it works pretty wonderfully. The LetsEncrypt integration works really well. I don't really have any interest in plugins personally, but this is still quite an amazing project.

I never built Traefik successfully. The same is for tag v2.3.0. $ go build ./... go: finding module for package github.com/traefik/traefik/v2/autogen/genstatic cmd/traefik/traefik.go:18:2: module github.com/traefik/traefik@latest found (v1.7.26), but does not contain package github.com/traefik/traefik/v2/autogen/genstatic

In order to build Traefik you have to get go-bindata and run the go generate command. You can find more information on https://doc.traefik.io/traefik/contributing/building-testing...
Fantastic, looking forward to playing with this.
> Rather than being pre-compiled and linked, however, plugins are executed on the fly by Yaegi, an embedded Go interpreter. Woof, no thank you. Go is basically incompatible with any kind of plugin-like dynamic linking. There are basically two reasonable models for doing something like plugins: the HashiCorp model, where plugins are actually separate processes that do some kind of intra-process communication with the…
Plugins and scripting languages flourish when they democratize the process of adding features to a piece of code. To have prebuilt binaries you need a build matrix, and the complexity of the build matrix is somewhere between exponential and factorial.
This is a perverse incentive for the curators. The cost has to be justified, and as the friction grows you can only justify the things that you have a strong affinity for. Anything you don't understand or don't like gets voted off the island.
In the best addon ecosystems, the core maintainers put some safety rails on the system so the addons can't do anything too crazy. Then they watch the cream of the crop and start trying to include them in the base functionality (limiting the number of optional features the majority of their users have to manually pick). The hard part here is how to reward the people whose ideas you just co-opted, and I don't have a great answer for that (although money and/or a free license for life is a good start)
I really wish Go plugins got some more love from the go team. It looks like this is using Yaegi a Go interpreter, which is probably the only reasonable choice. Go's plugin package requires that the plugin be compiled with exactly the same compiler version as the main binary. So you need to recompile every plugin for every new release, at least if you upgrade the compiler between releases which you often do. It also d…
The use case in our Hackerspace was to dispatch different Docker containers through our wild-card subdomains. Traefik is supposed to also automatically create TLS certificates. I had numerous problems with the Let's Encrypt functionality.
Debugging information is quite cryptic, the documentation seems all over to me, which is even more problematic given the number of breaking changes between 1.x and 2.x versions. The way you automatically configure things through Docker labels means that a simple typo can render your configuration ignored.
Also, plugging in Traefik to complex docker-compose projects such as Sentry or Gitlab is next to impossible, because of networking: whatever I tried, Traefik just couldn't pick up containers and forward to them unless I changed the definition of every single container in the docker-compose to include an extra network. I don't feel this should be this complex.
Sometimes I just feel that we should get back to using Nginx and write our rules manually. While the concept of Traefik is awesome, the way one uses it is extremely cumbersome.
