Julia DiffEq Dev Env

We'll base our environment off of our Minimal Bash image. Note that the Julia version is set as an environment variable on the runtime.

Julia 1.1 Minimal (Bash)

Type: Nextjournal

Environment:

Resources:

Environment Variables:

PATH	/usr/local/julia/bin:/usr/local/nvidia/bin:/usr/local/cuda/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Download this environment as a Docker image from:

tarArch='x86_64'

JULIA_VERSION_SHORT=${JULIA_VERSION/-rc/}
FILENAME="julia-${JULIA_VERSION}-linux-${tarArch}.tar.gz"
FILEURL="https://julialang-s3.julialang.org/bin/linux/${dirArch}/${JULIA_VERSION_SHORT%[.-]*}/${FILENAME}"

echo "Downloading ${FILEURL}."

curl -fL -o julia.sha256 \

echo `grep $FILENAME julia.sha256 | cut -d " " -f1` > j256sig

The JSON package is required to run on Nextjournal.

Julia 1.1 Minimal (Bash)

Build Julia 1.1

We'll add a number of packages as well as the libraries and support programs required by them. The major packages installed are JuliaPlots along with the GR and PlotlyJS backends, Makie, and the DataFrames, CSV, and HDF5 data-handling packages. The setup requires a GPU node for Makie to successfully precompile, but not to transclude and use unless Makie itself is needed.

First we'll check that the minimal Julia env works.

Some Julia packages require gcc to compile, so first we'll install that, as well as various required tools and libraries.

apt-get -qq update
apt-get install --no-install-recommends \
  imagemagick libhdf5-dev hdf5-tools mesa-utils \
  build-essential gfortran cmake automake libtool libltdl-dev pkg-config \

Plots also needs FFmpeg to create animations, so we'll install a 64-bit static build from an install package we download in the Appendix.

IDIR="/usr/local/ffmpeg"

mkdir -p $IDIR
cd $IDIR

tar -Jxf ffmpeg-release-amd64-static.tar.xz
 --strip 1

for ex in $IDIR/{ffmpeg,ffmpeg-10bit,ffprobe,qt-faststart}; do
  ln -s $ex /usr/local/bin/
done

Next the Julia package installs. Bugfix: Makie release fails to precompile, recommendation is using #master for Makie, GLMakie, and AbstractPlotting—mpd, 9 Dec 2018.

Finally, add font defaults for JuliaPlots and Makie. These named Code Listings will be mounted as files to the runtime's filesystem, and saved with the environment.
