I was in the audience when you gave the 5-minute docker lightning talk at PyCon US Santa Clara in 2013. I remember chatting with a friend/colleague about it (https://nvie.com/about/) and we both agreed it was the most interesting lightning talk that day. What’s funny, though, is that since it was “just” a lightning talk, it didn’t even make it into the roundup of notes I sent to my team after PyCon. But a mere year later, Docker was how my team (and seemingly everyone else) ran projects locally. Any interesting memories from that day in 2013? From your perspective, what happened in the year that followed that caused docker to be adopted so widely? Were there other key moments or turning points?

I'm a big fan of docker and mainly just want to say thanks for bringing it about. I remember my first time trying to use a container was about 2015 on a beach cafe's wifi in Bocas del Toro, Panama. You can imagine how it went... After a brief hiatus though I was back to it and since then it's been a core part of many a local dev stack and even production stack (compose) I've set up. I recall the magic moment for me being when I first realised you could mount src to use all your local native dev tools while completely virtualising everything else, including and especially whatever combo of runtimes and dependencies you need. It was just a lightbulb moment, like it entirely solves 'works on my machine', setting new people up on a project, it just seems like how software engineering ought to work and once you have experienced it it's difficult to go back. I'm curious, as its creator are you still using it, or as someone who can clearly look ahead to experimental ways of doing things are you on to the next thing whatever that may be? If so, what is it? :-)

Thank you for inventing Docker, it truly changed the life of many developers. I was there when dotCloud announced Docker in 2013 and it was truly pragmatic. I had previously burned my hands on LXC, Juju Charms and Vagrant to containerize the apps, but it was all a house of cards. I remember helping a friend ship his whole Vagrant Box to the interview panel for a job! It’s incredible to think about how much boilerplate Docker removed right at it's launch. Thank you.

I'm curious what made think of it in the first place? What was your thought process that made you think that these Linux primitives give the opportunity to make it a platform for distributing and deploying packaged applications and eliminating a lot of the issue around "it works my machine" argument? You may have already answered this somewhere, so feel free to tell me what to search for or if you have a link to hand, that works too :)

Hi, question from a sysadmin / network engineer. Why localhost with port forwarding? Why not native mechanism like routing and mdns? I’ve gave Docker and other container managers which do networking the same way a try a few times and I always found the network unnecessarily complicated. Eventually I came across OrbStack which uses the aforementioned mechanisms. Every container gets an IP address in the local bridge and responds to mdsns queries. This plays especially well in “compose” scenario when services on containers can all use original port numbers. And containers can be accessed with hostnames, so there won’t be conflict between port numbers especially if I run multiple composed stacks.
