RUST sample

This sample demonstrates how a rust application can be run in Mystikos

It is recommended that you understand how to use EXT2 file system and how applications can be packaged Mystkos before proceeding with this sample. Please refer to the README for the helloworld sample to obtain the necessary information.

Transform a Dockerfile into a root file system

Dockerfile imports from a base RUST image and builds src/hello with Cargo. myst-appbuilder is used to convert the Dockerfile into a directory containing all the files needed to run this application in Mystikos.

myst-appbuilder -v -d Dockerfile

After this, the appdir generated can be converted into a cpio archive using myst mkcpio or an EXT2 file system using myst mkext2that can be loaded into Mystikos. In this sample, we use an EXT2 file system.

Functionality

This sample prints hello world from a RUST application. The source code is contained in /hello/src/main.rs.

Running the sample

To run the sample in package mode, use make run.

To run the sample using myst exec-sgx, use make runexec.

Configuration parameters

The configuration used in this sample is very similar to that in the helloworld sample. Please refer to the helloworld sample for more details.

{
    // Mystikos configuration version number
    "version": "0.1",

    // OpenEnclave specific values
    "Debug": 1,
    "ProductID": 1,
    "SecurityVersion": 1,

    // Mystikos specific values
    "HostApplicationParameters": true,
    "MemorySize": "40m",
    "ApplicationPath": "/app/hello"
}
