Problems deploying a trame app using VtkRemoveView in Docker (with cookiecutter)

[loisvazquezind]

Hello.

I have been trying to deploy the finite element analysis example (https://github.com/Kitware/trame/tree/master/examples/06_vtk/Applications/FiniteElementAnalysis) in Docker using the cookiecutter (https://github.com/Kitware/trame-cookiecutter) tool. When I deploy the app using the VtkLocalView, all works fine, but when I deploy it using the VtkRemoveView, the application does not render well: I almost access the app but I got the "Connection closed" spinner. Is there any limitation for deploying a VtkRemoveView in Docker or I could have another error?

Thanks in advance.

Default VTK can not work within docker. In order to solve your problem you need to either use vtk-osmesa (CPU) or vtk-egl (GPU).

You can see a simple docker example using vtk here.

@loisvazquezind can you run the mentioned example without errors?

Hi. Yes, I can try and it works. I also try to run it with cookie-cutter and also works. Thanks.

Hello again.
I deployed the example on the GPU following the instructions described here, but the performance in the remote view is even worse than using the CPU I'm using vtk-egl instead of vtk-osmesa and using the 'kitware/trame:glvnd' as the base image in the Dockerfile instead of 'kitware/trame:py3.9'. Do I need to configure anything else?

Thanks, that works!
