Okay, so I messed around with Fabio today, specifically checking out the “fabio images” thing. It wasn’t super straightforward at first, but I figured it out, so I thought I’d scribble down what I did in case it helps someone else.

Getting Started
First, I needed to actually get Fabio. I already had Docker and Docker Compose on my machine, so that part was easy. If you don’t, you’ll need to install those first. Go get ’em!
Then I went searching online about how install fabio, and found a good docker compose file to get it running.
Pulling the Image
So, the docker compose file took care of this next part, but basically it’s using the `fabiolb/fabio` image. This seemed to be the go-to image from what I could tell.
I double-checked the docker hub to make sure that image actually existed, and made sure to grab a recent version, just in case. No point in using old stuff, right?
Configuring Fabio
After getting the container to run, I poked around at the files. The main thing is the `*` file. This is where you tell Fabio how to route traffic.

I’m not gonna lie, it took me a bit of trial and error to get the routing right. I had to read the documentation a few times. The basic idea is you add lines that tell Fabio “if the request looks like this, send it to that service.”
My configuration ended up looking something like this (I’ve simplified it a bit):
*/foo strip=/foo route to myservice:9999
Don’t quote me on that exact syntax, though. Always double-check the official docs!

Testing it Out
Once I thought I had it configured, I fired up a simple web server (just a basic “Hello, world!” thing) on my machine, listening on port 9999. I used a service I already had running, actually.
Then, I used curl in my terminal to send requests to Fabio’s address (which is usually something like localhost:9999, depending on your setup). I tried hitting different URLs to make sure the routing was working the way I expected.
The first few tries? Yeah, they didn’t work. I got some errors, went back to the `*` file, tweaked some things, restarted Fabio, and tried again. Rinse and repeat. It’s all part of the fun, eh?
Finally, Success!
Eventually, I got it working! I could hit different URLs and Fabio would correctly route the requests to my test service. Victory!
It wasn’t the smoothest process, but I learned a lot. The key takeaways for me were:

- Read the docs! Seriously, the Fabio documentation is pretty good, even if it takes a bit to wrap your head around it.
- Be patient. Getting the routing just right can take some fiddling.
- Test, test, test. Don’t assume it’s working until you’ve actually sent some requests and seen the results.
So, that’s my Fabio adventure for the day. Hopefully, this rambling account of my struggles is helpful to someone out there. Good luck, and happy routing!
