Toolboxes not available inside the container when connected through vnc.

[matifali]

I have a custom Dockerfile where I install more toolboxes.

USER matlab

When I launch it using,

docker build -t test-matlab:latest .
docker run -it --rm -p 5901:5901 -p 6080:6080 --shm-size=512M test-matlab:latest -vnc

I get this,

[matifali]

Why are my toolboxes not installed?

[matifali]

More context

While running withy the -browser flag I see all toolboxes.

docker run -it --rm -p 8888:8888 --shm-size=512M test-matlab:latest -browser

@matifali I believe there is a minor bug in your Dockerfile - you have assumed that MATLABROOT where MATLAB is installed is /opt/matlab (by specifying --destination=/opt/matlab in the build file). In fact this is /opt/matlab/R2022b (as you can see from the image below obtained by running mathworks/matlab:r2022b with -vnc and asking what matlabroot is.

Could you try changing your Dockerfile to install in the correct location and see if that fixes things?

Also you may find this Dockerfile useful as an example of how to extend the image mathworks/matlab to incorporate other products and third-party tools.

Thanks @josmartin for pointing that bug. This fixed the issue. But I am wondering why i was able to see all toolboxes in the browser version.

[josmartin]

@matifali I suspect that with the -browser flag they weren't really there (as I'm sure they won't work if installed NOT in $MATLABROOT/toolbox) but ver perhaps picked up their existence in the wrong place and wrongly reported it.
