Does MathWorks support a Docker image for MATLAB? How do we create a Docker image with MATLAB installed?

I want to create a Docker image with MATLAB installed. How do I do this?

Is there any official documentation to show me how to do this?

Answer 1

[MathWorks Support Team]

Yes, instructions for creating a MATLAB Docker container image are available on GitHub:

https://github.com/mathworks-ref-arch/matlab-dockerfile

At this time, we only recommend using MATLAB in a Docker container with Network licenses, but we are working on expanding support to other license options.

From a licensing standpoint, the Software License Agreement (SLA) includes virtual machines in the definition of a "Computer" and therefore allows the use of products in a virtual environment, except in the case of Designated Computer. The Designated Computer License Option only allows use on a single, physical (not virtual) designated Computer. The only exception to this rule is if the Designated Computer License option is used on a Automation Server that is virtual. Please see our Program Offering guide (p.14) for more information.

In addition to GitHub, the MATLAB container is also now available in dockerhub!

when I mount a matlab license into a matlab container, it returns th folllowing error:

The hostid of your computer (02420ac80002) does not match the hostid of the license file (6aeeb73d).

Is it possible that your license was created based on a windows host id (8 character volume serial number) but you are running the linux-based matlab image?

On linux, the relevant host id is the mac address of a network adapter (run ifconfig and look for the value next to "HWaddr").

But as far as I know, only network licenses are supported (not from a licensing perspective but for technical reasons). The main concern with a host-id based license is that the host-id of a container is not the same each time you start it.

Hi @David Willingham,

I have a similar question but in a different context.

The company that I have been working on has a license with "n" toolboxes.

In our CI, when the Jenkins node is executing a stage that uses Matlab, our verification engineers need to wait for that execution, otherwise, they will get "License Manager Error -9", therefore, it is our bottleneck.

I was wondering if is possible to create a MatLab docker image that can be shared throughout our company to avoid that bottleneck, so the question is, can I use that Matlab docker image mentioned by you and execute a container on a laptop, on-premises server, or cloud server at the same time?

Is it feasible/possible? In case it does not, could you please summarize the constraints? If so, can I just create our customized MatLab docker image and start running the container everywhere, or do I need something else?

I guess so because I do not see any information related to that on https://de.mathworks.com/help/install/administer-network-licenses.html

Am trying to implement something similar to this as it would be great to dockerize Matlab workflows.

Any progress on this issue you could share?

Bumping because I have similar needs using containerized Matlab.
