pvpython can not be used in kubernets

Web Support

I want to create a web visualization application based on ParaView. I used code from the trame framework. When building the Docker image, I adopted the Linux version downloaded from the official website: ParaView-5.12.0-RC1-osmesa-MPI-Linux-Python3.10-x86_64.

Part of my Dockerfile is as follows:

dockerfileCopy code

FROM python:3.10

## Install ParaView
ARG paraview=ParaView-5.12.0-RC1-osmesa-MPI-Linux-Python3.10-x86_64
COPY ${paraview}.tar.gz /tmp/
RUN tar -xzf /tmp/${paraview}.tar.gz -C /tmp/ && \
    mv /tmp/${paraview} /opt/paraview && \
    rm -rf /tmp/${paraview}.tar.gz
RUN apt-get update && \
    apt-get install -y libgl1-mesa-glx libgl1-mesa-dri
    
ENV PATH="/opt/paraview/bin:${PATH}"

I was able to launch pvpython on my own computer using docker run -idt MyImage pvpython. However, when I deploy it to the Kubernetes server, it throws an error:

cssCopy code

root@paraview-7f688cf59f-c2h46:/app# pvpython
error: exception occurred: Illegal instruction
```"

Is the K8s server running an older CPU at all?

This seems to be a CPU from 2010 or so. I would call it too old for ParaView these days. We definitely have code that wants more advanced vectorization support than can be provided here.

It seems that the CPU doesn’t support libOSmesa.

Yes, I can imagine that OSMesa has a lot of vectorized code in it.
