Configure Containers

When you start a container using the docker run command, you can configure its run time behavior. To do this, you can set environment variables inside the container by using the -e flag when you run the docker run command. This page describes some of the environment variables that you can use to configure MathWorks^® containers.

Configure Desktop Access Password

To change the password to access the desktop in the container via VNC or from a web browser in containers that allow this, you can use the following option:

-e PASSWORD=MyNewPassword

Add this option to the docker run command when deploying the container.

Configure Proxy Settings

If you are using a container inside a network that connects to the internet via a proxy server, you can specify your proxy server address when you run the container. If you are using MATLAB^® with online licensing, you need to specify your proxy server to be a be able connect to the MathWorks online licensing servers.

If you are using the MATLAB Container on Docker Hub, then specify the proxy server address using the environment variable PROXY_SETTINGS:
```
-e PROXY_SETTINGS=<proxy-server-address>
```
If you are using the MATLAB Deep Learning Container on NVIDIA GPU Cloud for NVIDIA DGX, then specify the proxy server address using the environment variable NGC_PROXY:
```
-e NGC_PROXY=<proxy-server-address>
```

Add these options to the docker run command when deploying the container.

You can specify the proxy server address using any of the following forms:

hostname:12345
shorthostname:12345
http://hostname:12345
http://username:password@hostname:12345
IPaddress:12345

where hostname is the fully qualified domain name, shorthostname is the relative domain name, and 12345 is the port number.

Network License Manager

If your license is administrated via a network license manager, you can use this license with MathWorks containers. You can point to the location of the license in the docker run command. Add the option:

-e MLM_LICENSE_FILE=27000@MyLicenseServer

Add this option to the docker run command when deploying the container.

Further Configuration Options

For advanced users, further configuration of the container deployment is available through additional Docker^® options. For more information, see the Docker documentation.
