> Docker’s container runtime, runc, is written in Go.

I worked at Docker from 2014-2019. The most important part is actually written in C.

[I wrote a whole comment here about to explain how the hack works because I was too fixated on how technically incorrect "written in Go" is. Then I went back to read the rest of the article only to see that the paragraph immediately after this kind of explains it in its own way! Let that be a lesson to always finish reading the article before posting about it.]
