alt Hacker NewsI listed some popular languages that web applications I happened to run dockerised are using. They are not arbitrary.
If you run normal web applications they often take many hundreds of megabytes if they are built with some popular languages that I happened to list off the top of my head. That is a fact.
Comparing that to cut down frameworks with many limitations meant for embedded devices isn't a valid comparison.
1GB is plenty for almost every case I've seen, 10-20x the need. Yes if you're running a repeated full OS underneath (hello VMs) then it'll waste more.
I run (regular) .NET (8) in <50mb, Javascript in <50mb, PHP in <50mb. C, Perl, Go in <20mb.
Unless you're talking about disk space.. runtimes take space.
