mosadm build-matlab-image

Build MATLAB Docker image for use in MATLAB Online Server

Since R2020a

Syntax

mosadm build-matlab-image

mosadm build-matlab-image matlabInstallLocation

mosadm build-matlab-image [matlabInstallLocation] option1 ... optionN

Description

mosadm build-matlab-image builds a MATLAB^® image from the default MATLAB install location, /MATLAB.

mosadm build-matlab-image matlabInstallLocation builds a MATLAB image from the specified MATLAB installation location.

mosadm build-matlab-image [matlabInstallLocation] option1 ... optionN builds a MATLAB image using the specified configuration options and either of the previous syntaxes.

Note

mosadm build-matlab-image interacts with Docker^®. If you do not have sudo administration privileges for Docker, then this command also requires sudo.

Examples

Build MATLAB Image from Specified Location

sudo ./mosadm build-matlab-image /Programs/MATLAB

Specific to mosadm build-matlab-image

Option	Description
--deployment-image-registry registryName	Image registry to use for the deployment. Example: registry.yourcompany.com
--deployment-image-repository repositoryName	Image repository to use for the deployment images. Example: mathworks
--tag tagName, -t tagName	Image name and optional tag to use for the deployment images. Specify tagName as a string of the form name or name:tag. Example: mos-matlab-image Example: mos-matlab-image:R2024a
--extra-reserved-file-system-space numGBs	Extra reserved file system space for image, in GB. Specify numGBs as a numeric scalar. Default: 0.1
--image-flavor imageFlavorName	Container image flavor, specified as debian or rhel. Default: debian

Common to All mosadm Commands

Option	Description
--charts-dir chartsDir	Name of the MATLAB Online Server™ charts folder to use. This folder contains the Helm® charts of the server. Specify chartsDir as an absolute path or a path relative to the MATLAB Online Server root folder mosRoot. Example: matlab_online_server/charts. Default: mosRoot/charts
--data-dir dataDir	Name of the MATLAB Online Server data folder to use. Specify dataDir as an absolute path or a path relative to the MATLAB Online Server root folder mosRoot. Example: matlab_online_server/data. Default: mosRoot/data
--dry-run	Print out the commands that would have run without this option specified but do not run the operation. Specify this option to test that the operation produces the expected results before actually executing it.
--help, -h, help	Output help for mosadm build-matlab-image to the command line.
--kube-config configFilePath	Path to the Kubernetes® cluster configuration file. Specify configFilePath as an absolute path or a path relative to the MATLAB Online Server root folder mosRoot. Example: /etc/kubernetes/admin.conf By default, configFilePath is empty and Kubernetes obtains the cluster configuration from the KUBECONFIG environment variable (if specified) or the ~/.kube/config file. If you run mosadm build-matlab-image with sudo, then ~/.kube/config is equivalent to /root/.kube/config.
--mos-root rootDir	MATLAB Online Server root folder, specified as an absolute path or a path relative to the current folder, that is, the folder in which you can run mosadm commands. Default: . (current folder)
--overrides-dir overridesDir	Name of the MATLAB Online Server overrides folder to use. Specify overridesDir as an absolute path or a path relative to the MATLAB Online Server root folder, mosRoot. Example: matlab_online_server/overrides Default: mosRoot/overrides
--quiet, -q	Print only the most useful or relevant output from the mosadm build-matlab-image command.
--skip-log-file	Skip creating the install.log file and logging data about the mosadm build-matlab-image operation to this file.
--skip-prompt, -y	Force acceptance of the terms of use for the mosadm build-matlab-image and skip any command-line prompts normally provided when calling this command.
--tmp-dir tempDirName	Name of MATLAB Online Server temporary folder to use. Specify tempDirName as an absolute path or a path relative to the temporary folder. By default, mosadm build-matlab-image generates a new temporary folder every time you run the command.
--verbose	Output extra details about the mosadm build-matlab-image operation to the command line.

Tips

• To build this image, your machine must have a TMPDIR environment variable that specifies a writable temporary directory mounted in exec mode. To mount TMPDIR in exec mode, run this command.

  mount -o remount,exec /tmp

  If you are unable to make the /tmp folder writable or you cannot mount folders in exec mode, then set a custom temporary directory by setting the --tmp-dir option, where

  mosadm build-matlab-image --tmp-dir tempDirName

  Here, tempDirName is the name of a directory that is writable and mounted in exec mode.

• If you are using a CIS hardened image, the /tmp directory or directory specified by --tmp-dir must be have executable permissions. For more details, see CIS Hardened Images.

• If you are using a snap install of Docker, the /tmp directory or directory specified by --tmp-dir must be under the $HOME directory. For more details, see https://snapcraft.io/install/docker/ubuntu.
