digitalmars.D - What's our container story?

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.

[Kaj Nackes 
post](https://dlang.org/blog/2019/03/14/containerize-your-d-
erver-application/) on our official blog is probably the best starting point.

Personally, I use Nix to build my docker containers. I don't have 
to know much about Docker, in fact I've never written a 
dockerfile! I also get extremely small containers since Nix will 
only put what really is needed to the container. No base OS image 
needed! It does mean you have to learn Nix and most likely also

Previously there was most up-to-date repo from China:
https://github.com/dlangchina/docker-dlang/tree/master

But now dlangdockertized is handled by Elias and Jonas - I would 
say should be recommended image for usage.

As usual DLF doesn’t care about production level things, but at 
least we have some heroes in community :)

I've been maintaining a Docker image for DMD for a while now:
🔗 https://hub.docker.com/r/starxen/dmd

It supports both Linux-based containers (Debian, Ubuntu, Fedora, 
openSUSE) and Windows containers.
I'm trying to follow the same standards as the official Docker 
images like PHP or Node.js – aiming for clarity, modularity, and 
best practices.

The image is kept up to date with the latest DMD versions.

You'll find links to the documentation, GitLab repo, CI pipeline 
history, and more in the description.

If you're using Docker and DMD – feel free to try it out and 
share any feedback 🙂

I also recently tried building [docker 
images](https://hub.docker.com/r/kirillsaidov/dlang) for D tool 
chain. Implemented 
[Dockerfiles](https://github.com/kirillsaidov/dlang-docker) for 
both DMD and LDC2 compilers using `ubuntu:24.04` as base image.

Also this container based on Debian looks well maintained

Unfortunately, the semi-release schedule of upstream project(s) 
makes things a bit semi-plannable ^^

I was looking forward to pre-build and push container images for 
the latest DMD release after the corresponding LDC release. Which 
eventually happened only a few weeks before what would have been 
the “approximate release date” of a future DMD release. 
Furthermore, I was also excited for a certain patch update of DMD 
to be released which hasn’t happened either (yet).

Please note that I’m only trying to explain why there hasn’t been 
a container image release. I do *not* want to shift blame to 
upstream maintainers; they have valid reasons that justify the 
current situation.

That said, up-to-date Containerfiles — aka Dockerfiles — are 
available:
<https://github.com/dlang-dockerized/containerfiles>

If one has a bit of CPU time to spare, one can easily build them 
on their own, too.

I've been using automated pushes by GH-action to support my own 
container for some time now, even though the LDC project offers 
recent (>=v1.40.1) alpine-tarballs.

The latest ldc2 and opend-ldc for x86_64/aarch64 are provided in:
