Can't open window in docker headless even tried xvfb, no-sand-box

[dlintw]

I'm runing Arch Linux with these packages installed

• electron 7.1.7-1
• xorg-server-xvfb 1.20.6-3
• julia 2:1.3.1-1

In command line shell, I could run electron by 'electron --no-sandbox', here is the command for launch julia

export ELECTRON_PATH=/usr/bin/electron
xvfb-run julia

In the julia, I type in these command

using Blink
w = Window(Dict("webPreferences.sandbox"=>false))

Still got the following error messages

ERROR: IOError: connect: connection refused (ECONNREFUSED)

I can reproduce this using the Julia 1.3 image.

docker run --rm -it julia:1.4

# At container prompt
apt update && apt install -y unzip xvfb
julia -e 'using Pkg; Pkg.add("Blink")'
julia -e 'using Blink; w = Window()'

Hi, I had a similar problem and I found the following workaround: you can open a window in your browser, similar to what people do for reading a jupyter notebook from docker.

First, start docker with

docker run --rm -it -p 8700:8700 julia:1.4

then in the Julia prompt, start the server as follows:

using Sockets
using MeshCat
vis = Visualizer(MeshCat.CoreVisualizer(ip"0.0.0.0", 8700), ["meshcat"])

you should be able to reach the url at http://localhost:8700/
