Subject: Creating a docker image with Guix
Date: Mon, 2 Jan 2017 13:54:30 +0100 [thread overview]
Message-ID: <idjbmvpwrjt.fsf@bimsb-sys02.mdc-berlin.net> (raw)
Hi Guix,
I just played around with Docker and built up a command to create a
Docker image for Emacs.
Can anyone find a more elegant way to do this?
--8<---------------cut here---------------start------------->8---
guix environment --ad-hoc \
coreutils bash emacs-no-x-toolkit -- \
sh -c 'tar -c $(guix gc --requisites $GUIX_ENVIRONMENT) | \
docker import -c "ONBUILD RUN [\"$GUIX_ENVIRONMENT/bin/ln\", \"-s\", \"$GUIX_ENVIRONMENT/bin\", \"/bin\"]" - emacs-base' \
&& echo -e "FROM emacs-base\nCMD [\"/bin/emacs\"]" | \
docker build -
--8<---------------cut here---------------end--------------->8---
What happens here is this:
* using “guix environment” build a temporary profile containing
coreutils (for “ln”), bash (for “sh”), and emacs
* inside the environment $GUIX_ENVIRONMENT points to the profile; take
all of the requisites for this profile (“guix gc --requisites”) and
send them to “docker import” using a tar pipe
* modify the base image such that it links the profile’s “bin” directory
to “/bin” when a derivative image is built
* name that base image “emacs-base”
* then build a derivative of this base image with “docker build” (this
causes “ln -s” to be executed) and make it run the command
“/bin/emacs” by default
The result is an unnamed image (“docker build” reports an image id such
as “ae8d6281b56f”) that can be run interactively like this:
docker run -it --rm ae8d6281b56f
What do you think? Gross?
