  • HAproxy is good at what it does but it’s only good at proxying and simple rules.

    It’s possible to write very complex rules/ACLs with HAproxy… stick-tables, ACLs with regexes on whatever HTTP header, source or destination ACLs, map files, geoblocking, lua scripting, load-balancing from round-robin to host header load balancing, dynamic backend servers provisionning through DNS… Not that you can’t do it with Nginx (it started as a reverse-proxy before becoming a jack of all trades), nor that nginx isn’t a great tool (it is!), but HAProxy can do very complex things too. It also follows the good ol’ UNIX philosophy of “one program to do one thing and do it well” and thus doesn’t try to be a webserver, hence why you need a webserver behind it to serve anything from static files to PHP/Python/whatever.


  • You’re welcome! scratch and distroless are indeed basically the same thing, scratch being the ‘official’ docker minimal image while distroless is from google - as I’m more a Kubernetes user (at home and at work) than a Docker user, I tend to think about distroless first :) - my apologies if my comment was a bit confusing on this matter.

    By the way, have fun experimenting with docker (or podman), it’s interesting, widely used both in selfhosting and professional environments, and it’s a great learning experience - and a good way to pass time during these long winter evenings :)


  • A bit late but you might want to have a look at docker multi-stage build documentation which does exactly what you did (start from a base image then copying stuff from it to your own image), something like that:

    FROM someimage:sometag AS build
    [do stuff]
    FROM minimalimage:someothertag
    COPY --from=build /some/file /some/other/file
    [and so on]
    USER somebody
    CMD ["/path/somecommand"]
    

    Which will simplify building new images against newer “build” image newer tags easier.

    btw, you were quite creative on this one! You also might want to have a look at the distroless image, the goal being to only have the bare minimum to run your application in the image: your executable and its runtime dependencies.





  • I use Vim since 31 years. Started in 1992, on Amiga with Fred Fish disks. I use Vim daily at work since 20 years. It’s like a second home for me, a familiar tool which makes me confident that it’ll help me manage whatever task I throw at it. I never had the pleasure to encounter Bram to tell him how much his work helped me throughout the years. I should have sent a “thank you for your hard work” mail when it was still possible. Now I can only send condolences. And some money to the ICCF. That’s the least I can do.
