Is it possible to create a Docker image from Simulink model?

Is it possible to create a Docker image from Simulink model? Could you provide an example if possible?

You can deploy a MATLAB function that simulates a Simulink model to Docker using MATLAB Compiler and Simulink Compiler. You will need MATLAB that is R2020b or newer. We suggest you use newer releases that are more stable and have more functionality.

Since Simulink Compiler generates platform-specific binaries and the fact that Docker containers are Linux based, you need to build and package on Linux.

Please refer to the following example steps.

1. Start with the following function.

function deployedScript()

  in = Simulink.SimulationInput('sldemo_suspn_3dof');
  in = in.setVariable('Mb', 1000);
  in = simulink.compiler.configureForDeployment(in);

  out = sim(in);
  plot(out.ScopeData.signals.values)
  pause(3)
  close(gcf)

end

2. ​Build the example into a standalone application.

>> r = compiler.build.standaloneApplication('deployedScript.m')

3. Package that executable into a Docker container. It may take a while.

>> compiler.package.docker(r)

4. Run the newly created container.

>> !docker run --rm -e "DISPLAY=:1.0" -v /tmp/.X11-unix:/tmp/.X11-unix deployedscript
