Julia 0.7 Environment

Setup

Build a Minimal Julia 0.7 Environment

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.

The JSON package is required to run on Nextjournal. Newest JSON.jl uses xparse from newer versions of Parsers.jl, which we can't install. —mpd, 20 Aug 2019

Build a 'Default' Julia 0.7 Environment

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, and the DataFrames, CSV, and HDF5 data-handling packages.

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 \
  libxt6 libxrender1 libgl1-mesa-glx libqt5widgets5 `# for GR` \
  libhttp-parser2.7.1 `# for PlotlyJS`
apt-get clean
rm -r /var/lib/apt/lists/* # Clear package list so it isn't stale

Plots 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

Install packages. Fixing Plots at v0.19.3, the current final 0.7 version. This seems to clear up some other version/dep issues. —mpd, 16 Dec 2018. Added JSON version here, because pinning apparently doesn't work. —mpd, 20 Aug 2019.
