Notes on the dtplugins Helm Chart

Overview

The dtplugins Helm Chart deploys the Digital Twin CAD Plugins web application. As of Release 5.1 the CAD Plugins are no longer included in the dtplatform chart and must be installed separately.

All resource names are prefixed with the {{ dtplugins.name }} function. This will result in a prefix of {{ Chart.Name }}- (unless using .Values.nameOverride). For example, the prefix would be dtplugins- if there is no .Values.nameOverride.

Note: All settings names listed below do not have the dtplugins- prefix since it can be updated by the installer. The Helm Chart will adjust the names as necessary.

Deployment Modes

The CAD Plugins application can be deployed two ways:

1. As a standalone nginx/web service serving the application directly
2. As a migration job that copies the static files to a shared PersistentVolumeClaim which is served by the staticwebsvc created by the dtplatform chart

The default values deploy in mode 2, which matches the default behavior of dtplatform.

To deploy in mode 1, set the following values:

ingress.ipaplugins.enabled=trueservice.ipaplugins.enabled=truedeployment.ipaplugins.enabled=truejob.ipaplugins-migrations.enabled=false

In this mode the staticwebsvc ingress in the dtplatform chart should not be configured to serve the app URL.

To deploy in mode 2, set the following values:

ingress.ipaplugins.enabled=falseservice.ipaplugins.enabled=falsedeployment.ipaplugins.enabled=falsejob.ipaplugins-migrations.enabled=truejob.ipaplugins-migrations.persistentVolumeClaimName=staticwebsvc

In mode 2 the dtplatform chart must be installed first so that the staticwebsvc PersistentVolumeClaim exists when the migration job runs.

Configuration Maps

The configuration maps (ConfigMaps) have references to environment variables (secret values) in the form of ${VARIABLE_NAME}. These are interpolated at runtime to avoid adding secrets to the Helm Chart values.

Global

The settings at config.global.* configure URLs that must match those configured in the dtplatform chart.

Key	Description	Default
config.global.url.app	URL for platform management applications	https://app.yourdomain.com
config.global.url.id	URL for platform identity management	https://id.yourdomain.com
config.global.url.api	URL for REST API	https://api.yourdomain.com
config.global.theme	Theme for installation (platform is only available value)	platform

External

The settings at config.external.* configure external services. The default values are empty and customer overrides are not typically required.

Internal

The settings at config.internal.* configure internal communication between the chart's resources. No changes or overrides should be made unless specifically directed by the support team.

Override

The settings at config.override.* configure per-resource overrides. The default values are empty.

Key	Description	Default
config.override.ipaplugins.*	Overrides for the ipaplugins deployment	{}
config.override.ipaplugins-migrations.*	Overrides for the ipaplugins-migrations job	{}
