Flags

Flags allow you to control the availability of certain features within Desktop Modeler.

Configuring Flags

You may configure flags in a flags.json file or pass them via CLI.

Configure in flags.json

Place a flags.json file inside the resources folder of your local {USER_DATA} or {APP_DATA_DIRECTORY} directory to persist them.

Configure via CLI

Pass flags via the command line when starting the application.

Windows

"Camunda Modeler.exe" --disable-plugins

macOS

camunda-modeler --disable-plugins

Linux

camunda-modeler --disable-plugins

Flags passed as command line arguments take precedence over those configured via a configuration file.

Available Flags

flag	default value
"disable-plugins"	false
"disable-adjust-origin"	false
"disable-cmmn"	true
"disable-dmn"	false
"disable-form"	false
"disable-platform"	false
"disable-zeebe"	false
"disable-remote-interaction"	false
"single-instance"	false
"user-data-dir"	Electron default
"display-version"	undefined
"zeebe-ssl-certificate"	undefined
"c7-engine-version"	undefined
"c8-engine-version"	undefined

Examples

Disable Plug-ins

Start the modeler without activating installed plug-ins. This is useful to debug modeler errors.

BPMN-only Mode

To disable the DMN and Form editing capabilities of the App, configure your flags.json like this:

{
    "disable-dmn": true,
    "disable-form": true
}

As a result, the app will only allow users to model BPMN diagrams.

Custom display-version label

To display a custom version information in the status bar of the app, configure your flags.json like this:

{
    "display-version": "1.2.3"
}

Zeebe SSL certificate

ℹ️ The Modeler will read trusted certificates from your operating system's trust store.

Provide additional certificates to validate secured connections to a Camunda 8 installation.

Configure your flags.json like this:

{
    "zeebe-ssl-certificate": "C:\\path\\to\\certs\\trusted-custom-roots.pem"
}

Additional information adapted from the upstream documentation:

The peer (Camunda 8) certificate must be chainable to a CA trusted by the app for the connection to be authenticated. When using certificates that are not chainable to a well-known CA, the certificate's CA must be explicitly specified as trusted or the connection will fail to authenticate. If the peer uses a certificate that doesn't match or chain to one of the default CAs, provide a CA certificate that the peer's certificate can match or chain to. For self-signed certificates, the certificate is its own CA, and must be provided.

Default execution platform version

To change default execution platform version, configure your flags.json as follows:

{
  "c7-engine-version": "7.18.0",
  "c8-engine-version": "8.0.0"
}

New diagrams created in Desktop Modeler will use the configured version instead of the latest stable version.
