I've had a couple of previous tries at setting up k3s. In a lot of stuff I read, Traefik seems to have less issues than nginx proxy- but is harder to set up. I've had huge issues with Traefik before, but wanted to do it this way to learn, and because it will hopefully result in a 'better' long term solution. But it's early days, I may still be forced to come back to a better documented solution by lack of talent...
