Run Locally

The DeltaTwin® Command Line Interface (CLI) enables you to run your DeltaTwin® component locally for testing and experimentation.


deltatwin run start_local -i inputs_file_example.json

inputs_file_example.json is a file containing all input values. Below is an example input file that takes as input the URL of the GAEL SYSTEMS logo and an angle value of 90 degrees:


{
  "image": {
    "type": "Data",
    "url": "https://platform.destine.eu/wp-content/uploads/2023/11/cropped-favDEPL-180x180.png"
  },
  "angle": {
    "type": "integer",
    "value": 90
  }
}

Local Run Limitation

When running DeltaTwin® components locally, some input types are not supported:

DriveData: Resources stored in DeltaTwin® Drive cannot be accessed remotely for local execution. You must download these files manually and update the manifest to reference the local path.
URL with SesamEO API Key

Run on DeltaTwin® cloud environment

DeltaTwin® service provides a cloud environment to store and run your DeltaTwin® project.

Publish

To proceed, you will need to publish your DeltaTwin® by using the command ‘DeltaTwin® component publish’ ( see (CLI Documentation )) for more details).

For example, to publish the previous rotation DeltaTwin® as version 0.1, enter:


deltatwin component publish -t demo -v private  0.1

the optional parameters indicates that:

-t demo is a topic name for referencing our project. Later, you will be able to search DeltaTwins by topic name.
-v private means that the DeltaTwin® is only visible to you. If you set to public the DeltaTwin®will be visible and runnable by any user.

The DeltaTwin® component is automatically published in the namespace associated with the current user account. Publishing to a different namespace is not supported.

Once published, you can remotely run your DeltaTwin® component either with the command line or by using the DeltaTwin® web application.

Run using CLI

The following command enables to get the DeltaTwin®


deltatwin component list

Now, use the name to run your DeltaTwin® component


deltatwin run start TWIN_NAME -i inputs.json

By default, the service runs the DeltaTwin® component located in the current namespace. To run a DeltaTwin® component outside the current namespace, specify the namespace using the -n option:


deltatwin run start TWIN_NAME -i inputs.json -n <namespace>
