What's our container story?

[Lance Bachmeier]

With Apple's [Containerization announcement 
yesterday](https://www.youtube.com/watch?v=JvQtvbhtXmo) and 
GitHub Codespaces running Linux containers, it appears the 
container thing is a big deal. I admit I don't know a lot about 
them beyond playing with Docker a few years back.

Looking at Docker Hub, I see there is an organization called 
dlangdockerized that makes semi-recent releases of DMD and LDC 
available. Do we have any getting started documentation 
available, and do we provide any other containers (for instance, 
to do web development)? I plan to use GitHub Codespaces for a 
class I'm teaching next semester. It would sure be nice to have 
some guidance on getting things up and running. This seems to be 
the extent of the documentation: `docker pull 
dlangdockerized/dmd` and then the user is on their own to figure 
out the rest.
