Available tags
--------------

The default tag (`latest`) is the last stable release.



```yaml
- image: dlang2/dmd-circleci:nightly
- image: dlang2/dmd-circleci:beta
- image: dlang2/dmd-circleci
- image: dlang2/dmd-circleci:2.078.0
```



```yaml
- image: dlang2/ldc-circleci:beta
- image: dlang2/ldc-circleci
- image: dlang2/ldc-circleci:1.6.0
```



```yaml
- image: dlang2/gdc-circleci
- image: dlang2/gdc-circleci:4.8.5
```

- https://hub.docker.com/r/dlang2/ldc-circleci/tags/
- https://hub.docker.com/r/dlang2/gdc-circleci/tags/

This repo is fully automated and new releases get deployed 
automatically.
It already has DMD 2.078.0.

Cheers,

PS: I'm aware of Stefan Rohe's great D Docker images [1], but 
this Docker image is built on top of the specialized CircleCi 
image (e.g. for their SSH login).

do you orchestrate your containers in deployment?

Oh I am not sure we are talking about the same thing. This 
CircleCi image is intended to be used for CircleCi _only_ and 
there's a lot of stuff you probably don't want to have in your 
production container:

https://github.com/wilzbach/dlang-docker/blob/master/circleci/template.docker

However, I also added dlang2/{dmd,ldc,gdc}-ubuntu images 
recently. Here's an example app built with DUB:

https://github.com/wilzbach/dlang-docker/blob/master/example-app/Dockerfile

However, note that this will install the respective D compiler in 
your image which typically actually don't need for your 
application (so again it's more intended for CI usage)
Hence, for my things I use `-static` and just COPY the binary 
into the docker image.
Here's an example of an Open-Source application, which I 
maintain, that does so:

https://github.com/dlang-tour/core/blob/master/Dockerfile
https://github.com/dlang-tour/core/blob/master/dub.sdl

It's a pity that D doesn't support Musl (a light-weight 
alternative to glibc) yet, but that might change soon [1].
Anyhow for now you can use glibc on alpine, e.g.:

https://github.com/wilzbach/dlang-docker/blob/master/alpine/dlang.docker

One useful characteristic of Stefan's images is that the 
Dockerhub pages include the Dockerfile and github repository 
links. I don't know what it takes to include them. It does make 
it easier to see exactly what the configuration is, find the 
repo, and even create PRs against them. Would be useful if they 
can be added to the CircleCI image pages.

My interest in this case - I use Stefan's LDC image in Travis-CI 
builds. Building the runtime libraries with LTO/PGO requires the 
ldc-build-runtime tool, which in turn requires a few additional 
things in the docker image, like cmake or ninja. I was interested 
if they might have been included in the CircleCI images as well. 
(Doesn't appear so.)

Oh, thanks for the hint! I added a link back to the repo:

https://github.com/wilzbach/dlang-docker

(FYI: the link was in my post)

Nope, it's not. Here's the list of the packages pre-installed:

https://github.com/wilzbach/dlang-docker/blob/master/circleci/dlang.docker

However, CircleCi gives you sudo rights by default and can simply 
add:


 sudo apt-get update && sudo apt-get install cmake


Note that the CircleCi Docker image was motivated to test 
PIE-hardening with DMD, but it's still WIP:
