&gt; Call me a simpleton but I am happy with better package management and config systems.<p>Fundamentally (in terms of process, not technical implementation) that&#x27;s all containers really are.<p>Run this, with this config file, and everything is pre-packaged for you in a bundle you can ship to your prod server if you like (or not, run it locally, whatever).<p>It&#x27;s quite nice. I shared the skepticism (&quot;so.. it&#x27;s just VM&#x27;s then? So what?&quot;) but having switched to a dev toolchain using it - it&#x27;s actually a LOT simpler than developing locally normally.
