Rails on Docker
I used to think I hated Docker, but I think what I actually hate is using Docker locally (building&#x2F;rebuilding&#x2F;cache-busting images, spinning containers up and down, the extra memory usage on macOS, etc etc). I don&#x27;t need all that for development, I just want to run my dang code<p>But I&#x27;ve been really enjoying it as a way of just telling a PaaS &quot;hey here&#x27;s the compiler&#x2F;runtime my code needs to run&quot;, and then mostly not having to worry about it from there. It means these services don&#x27;t have to have a single list of blessed languages, while pretty much keeping the same PaaS user experience, which is great
