Getting started with EDMM

The EDMM Modeling, Decision Support, and Transformation System consists of three components: (1) the EDMM Modeling Tool, (2) the EDMM Framework, and (3) the EDMM CLI.

---

Usage

Install and use the EDMM CLI

• Download the latest edmm.zip distribution package from the releases page
• Extract the files to a location on your filesystem and add it to your path variable (Linux: $PATH, Windows: %PATH%).
• Run the CLI: edmm -r <modeling-repository> transform <target> <input>

EDMM supports YAML files as input, according to the published YAML specification. Specified components and their respective component types must be supplied in a single file. An example shows the usage of the built-in types to model an application deployment based on virtual compute resources, e.g., virtual machines having some software components installed.

The generated deployment technology-specific models and artifacts will be stored relative to the YAML input file.

Run the EDMM Modeling Tool

Prerequisites:

• Git
• Docker and Docker Compose

Clone the repository:

git clone https://github.com/UST-EDMM/getting-started.git
git submodule update --init

Start the environment:

docker-compose up -d

Afterward, EDMM Modeling Tool is running on http://localhost:8080 and is preconfigured to support the types from the EDMM modeling-repository.

If you want to deploy the application on a server, change the PUBLIC_HOSTNAME in the .env file to your domain name or respective IP address before starting it with Docker Compose.

To terminate the system, run the following command:

docker-compose down

Getting Started with the EDMM Modeling Tool

After opening the EDMM Modeling Tool on http://localhost:8080, it displays a set of example applications, e.g., PetClinc and SockShop. You can see the graphical model of an application by clicking one of them.

Afterwards, navigate to the Topology Tempalte tab and click the Open Editor button.

A new browser window opens that presents the respective application structure.

Now you can enable the transformation check, to see which technology supports the currently modeled application. Click Show EDMM Transformation Check.

In the sidebar, hover over the different technologies to highlight the components that are not supported. If the transformation check is successful, you can trigger the transformation by clicking do transformation.

Alternatively, you can click show replacements to highlight how the structure need to be adapted to be supported by a certain deployment technology.
