How to check what Julia packages are installed in `jupyter/datascience-notebook`? - docker

Question

I'm in Julia x Jupyter project and I chose to use jupyter/datascience-notebook Docker Image which contains jupyterlab and Julia environment.
I want to know what package for Julia is pre-installed in jupyter/datascience-notebook and know what extra packages I need to install manually.
I read Dockerfile of datascience-notebook to know what package is installed in the jupyter/datascience-notebook image, but I could not find lines for designating julia packages.

How can I check out what Julia packages are installed in jupyter/datascience-notebook?

Answer 1

In your code julia -e 'import Pkg; Pkg.add("HDF5")' installs HDF5 package and it is the only package installed beside of IJulia.
If you want to show the list of packages installed in your Julia environment you can do:
julia -e 'using Pkg;Pkg.status()'
Looking at your code this will work correctly as long as you run it with the Julia depot location env variable set to: JULIA_DEPOT_PATH=/opt/julia
