Create a MATLAB Container Image

This repository shows you how to build and customize a Docker® container for MATLAB® and its toolboxes, using the MATLAB Package Manager (mpm).

You can use this container image as a scalable and reproducible method to deploy and test your MATLAB code.

Use the Dockerfile in this top-level repository if you want a lightweight and simple way to create a MATLAB container image. You can also download prebuilt images based on this Dockerfile from here.

For alternative resources, see the alternates folder that contains the following Dockerfiles:

The Dockerfile in matlab-installer uses the MATLAB installer rather than mpm to install MATLAB in the container. This allows you to install toolboxes that are not currently supported by mpm. Use this Dockerfile if you prefer using the MATLAB installer workflow, instead of mpm.
The Dockerfile in building-on-matlab-docker-image shows you how to build on top of the MATLAB Container Image on Docker Hub. Use this Dockerfile if you want to install extra toolboxes on top of the mathworks/matlab container image. This Dockerfile contains the features of the MATLAB image on Docker Hub, allowing you to access the dockerised MATLAB through a browser, batch mode, or an interactive command prompt.
The Dockerfile in non-interactive allows you run MATLAB in non-interactive environments. This Dockerfile requires that you have a MATLAB batch licensing token to license MATLAB in the container. Use this Dockerfile in continuous integration and continuous delivery (CI/CD) pipelines or other automated environments where interactive licensing is not possible.
The Dockerfile in matlab-container-offline-install shows you how to build and customize a Docker container for MATLAB and its toolboxes in an offline environment. Use this Dockerfile if you must build your container image in an offline environment.

Build Instructions

Get Sources

Access this Dockerfile either by directly downloading this repository from GitHub®, or by cloning this repository and then navigating to the appropriate folder.

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

Build & Run Docker Image

Build container with a name and tag of your choice.

docker build -t matlab:R2024b .

Run the container. Test the container by running an example MATLAB command such as ver.

docker run --init --rm -e MLM_LICENSE_FILE=27000@MyServerName matlab:R2024b -batch ver

The Dockerfile defaults to building a container for MATLAB R2024b.

The example command ver displays the version number of MATLAB and other installed products. For more information, see ver. For more information on running the container, see the section on Running the Container.

Note

Using the --init flag in the docker run command ensures that the container stops gracefully when a docker stop or docker kill command is issued. For more information, see the following links:

Docker run reference page.

Blog post on the usage of init.

Customize the Image

By default, the Dockerfile installs MATLAB for the latest available MATLAB release without any additional toolboxes or products in the /opt/matlab/${MATLAB_RELEASE} folder.

Use the options below to customize your build.

Customize MATLAB Release, MATLAB Product List, MATLAB Install Location and License Server

The Dockerfile supports the following Docker build-time variables:

Argument Name	Default value	Description
MATLAB_RELEASE	R2024b	The MATLAB release to install, for example, `R2023b`.
MATLAB_PRODUCT_LIST	MATLAB	Products to install as a space-separated list. For more information, see MPM.md. For example: `MATLAB Simulink Deep_Learning_Toolbox Fixed-Point_Designer`
MATLAB_INSTALL_LOCATION	/opt/matlab/R2024b	The path to install MATLAB.
LICENSE_SERVER	unset	The port and hostname of the machine that is running the Network License Manager, using the `port@hostname` syntax. For example: `27000@MyServerName`

Use these arguments with the the docker build command to customize your image. Alternatively, you can change the default values for these arguments directly in the Dockerfile.

Build an Image for a Different Release of MATLAB

For example, to build an image for MATLAB R2019b, use this command.

docker build --build-arg MATLAB_RELEASE=R2019b -t matlab:R2019b .

Build an Image with a specific set of products

For example, to build an image with MATLAB and Simulink®, use this command.

docker build --build-arg MATLAB_PRODUCT_LIST='MATLAB Simulink' -t matlab:R2024b .

Build an Image with MATLAB installed to a specific location

For example, to build an image with MATLAB installed at /opt/matlab, use this command.

docker build --build-arg MATLAB_INSTALL_LOCATION='/opt/matlab' -t matlab:R2024b .

Build an Image Configured to Use a License Server

Including the license server information with the docker build command means you do not have to pass it when running the container.

# Build container with the License Server.
docker build --build-arg LICENSE_SERVER=27000@MyServerName -t matlab:R2024b .

# Run the container, without needing to pass license information.
docker run --init --rm matlab:R2024b -batch ver

Use the Network License Manager

This container requires a Network License Manager to license and run MATLAB. You will need either the port and hostname of the Network License Manager, or a network.lic file.

Step 1: Contact your system administrator, who can provide one of the following:

The address to your server, and the port it is running on. For example: [email protected]

A network.lic file which contains the following lines:

# Sample network.lic
SERVER MyServerName.example.com <optional-mac-address> 27000
USE_SERVER

A license.dat file. Open the license.dat file, find the SERVER line, and either extract the port@hostname, or create a network.lic file by copying the SERVER line and adding a USE_SERVER line below it.
```
# snippet from sample license.dat
SERVER MyServerName.example.com <mac-address> 27000
```

Step 2: Use port@hostname or the network.lic file with either the docker build or the docker run command.

With the docker build command, either:

Specify the LICENSE_SERVER build-arg.

# Example
docker build -t matlab:R2024b --build-arg LICENSE_SERVER=27000@MyServerName .

Use the network.lic file:
1. Place the network.lic file in the same folder as the Dockerfile.
2. Uncomment the line COPY network.lic /opt/matlab/licenses/ in the Dockerfile.
3. Run the docker build command without the LICENSE_SERVER build-arg:
```
# Example
docker build -t matlab:R2024b .
```

With the docker run command, use the MLM_LICENSE_FILE environment variable. For example:

docker run --init --rm -e MLM_LICENSE_FILE=27000@MyServerName matlab:R2024b -batch ver

Run the Container

If you did not provide the license server information when building the image, then provide it when running the container. Set the environment variable MLM_LICENSE_FILE using the -e flag, with the network license manager's location in the format port@hostname.

# Start MATLAB, print version information, and exit:
docker run --init --rm -e MLM_LICENSE_FILE=27000@MyServerName matlab:R2024b -batch ver

You can run the container without specifying MLM_LICENSE_FILE if you provided the license server information when building the image, as shown in the examples below.

Run MATLAB in an Interactive Command Prompt

To start the container and run MATLAB in an interactive command prompt, execute:

docker run --init -it --rm matlab:R2024b

Run MATLAB in Batch Mode

To start the container, run a MATLAB command, and then exit, execute:

# Container runs the command RAND in MATLAB and exits.
docker run --init --rm matlab:R2024b -batch rand

Run MATLAB with Startup Options

To override the default behavior of the container and run MATLAB with any set of arguments, such as -logfile, execute:

docker run --init -it --rm matlab:R2024b -logfile "logfilename.log"

To learn more, see the documentation: Commonly Used Startup Options.
