Ich habe Alpine ausprobiert, und werde das Tutorial noch erweitern. Die build Zeit ist gefühlt genau so lang, oder noch ein bisschen länger. Die Grösse vom Final Image ändert sich auch kaum (15 Mb vs 16 Mb, mit `-b release` Argument). Die Grösse vom final Image lässt sich noch reduzieren wenn man die static libraries von druntime/phobos nimmt. Per default werden die SO Dateien eingebunden. Das macht auch noch ein paar MB aus.

Try out the Alpine image and see if it doesn't have the same issue with vibe-d. Also, if you report your problem with ldc here, preferably with a reduced sample, someone will take a look: https://github.com/ldc-developers/ldc/issues

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

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: https://github.com/dlang/dmd/pull/7579
