Host MATLAB Online in ICE Connect EKC. Run code on multiple Nvidia GPUs in parallel.

Requires a MATLAB license.

Helm Chart on GitLab


Install the app through Rancher.

Supported Docker images

This Helm chart can be used with MathWorks Docker images


Provides an Ubuntu-based image with an installation of MATLAB.


Also adds additional toolboxes:

  • Deep Learning Toolbox
  • Image Processing Toolbox
  • Parallel Computing Toolbox
  • More


Additional products and services

Before deploying MATLAB from Rancher, additional toolboxes can be installed from MathWorks Products and Services, such as Financial Toolbox and Optimization Toolbox.

Simulink is not supported by MATLAB Online.

SSH settings

MATLAB Online requires SSH access to the host machine. Add your SSH public key from e.g. ~/.ssh/


Requested CPU (required): The minimum number of CPU cores to request for the Jupyter server, in milli-CPU units (m). The default is 1000m, which is equivalent to one CPU core. More cores will be available freely depending on the server load, with a maximum of 64 cores.

Memory limit (required): The maximum amount of memory to request, in Gibibytes (Gi).

Storage size (required): The amount of persistent storage to request, in Gibibytes (Gi). The storage volume will be mounted in the /home/matlab.

Attach GPU (optional): If you want to use an Nvidia GPU, enable this option. Select the GPU type and the number of GPUs to request.

Environment variables

Read more about the environment variables in the MATLAB documentation for the Docker container.


The login portal of MATLAB Online opens the application up for anyone to access from a browser, so SSH port forwarding must be used (instead of ingress).

SSH port forward

In Rancher, look up the NodePort at Endpoint using Protocol: TCP

Endpoint                            Protocol           TCP

Log in as user matlab or root, and port forward the MATLAB web interface from port 8888:

ssh -p 31243 -L 9999:localhost:8888

Open http://localhost:9999 in your web browser.

Web interface

Log in using your MathWorks account, and access the application

Install packages at runtime

Add-on Explorer is not supported on MATLAB Online.

Packages from MATLAB File Exchange can be installed using the MATLAB Command Window

net = mobilenetv2();
Error using mobilenetv2
mobilenetv2 requires the Deep Learning Toolbox Model for MobileNet-v2 Network support 
package for the pretrained weights. 
To install this support package, use the Add-On Explorer. To obtain the untrained
layers, use mobilenetv2('Weights','none'), which does not require the support package.

Open the Deep Learning Toolbox Model for MobileNet-v2 Network, right-click Download, and Copy Link.

websave('mobilenetv2.mlpkginstall', '')

Continue with the example

net = mobilenetv2();

Verify GPU Environment

Use the MATLAB Command Window to verify the GPU Code Generation Environment

gpuEnvObj = coder.gpuEnvConfig;
gpuEnvObj.BasicCodegen = 1;
gpuEnvObj.BasicCodeexec = 1;
gpuEnvObj.DeepLibTarget = 'tensorrt';
gpuEnvObj.DeepCodeexec = 1;
gpuEnvObj.DeepCodegen = 1;
results = coder.checkGpuInstall(gpuEnvObj)

The output should be
