Introduction

Users accessing yuuvis® Momentum via a browser have to select their tenant before their credentials are requested. This tenant selection web page is provided by the AUTHENTICATION Service. In order to customize the design, it is possible to replace the underlying default form files by a set of custom form files.

Required Sources

A directory public has to be available in the root of the AUTHENTICATION service's container when the service is started. In this public directory, there must be at least the files tenant.html and error.html.

In the tenant.html file, the reference on http://www.thymeleaf.org (line 2) and the corresponding form definition are required (lines 11-–12) in order to provide the tenant selection functionality.

...

In the error.html file, the reference on http://www.thymeleaf.org (line 2) and the three span definitions are required (lines 8-–10) in order to provide error details.

The example custom form files used in this article are available for download as public.zip file.

Possible Procedures

There are different ways to proceed:

...

In this article, only the first procedure via Kubernetes ConfigMaps is described. The replacement of the default form files is explained by means of a simple example.

Configuration via Kubernetes ConfigMaps

By following these steps, you configure a simple custom web page for the tenant selection dialog:

• Add the following line in the authentication-prod.yml configuration file:

  Code Block
  language yml
  spring.thymeleaf.prefix: 'file:/public/'

  
  

• Unpack the public.zip file.

• Create a ConfigMap for the files in the public directory via the command:

  Code Block
  language bash
  kubectl -n yuuvis create configmap templates --from-file=./public/

  
  

• Adjust the Kubernetes deployment of the AUTHENTICATION service via the command:

  Code Block
  language bash
  kubectl -n yuuvis edit deploy authentication

  
  

• Extend the volumes section as follows:

  Code Block
  language yml
  volumes: - name: templates configMap: name: templates

  
  

• Extend the volumeMounts section as follows:

  Code Block
  language yml
  volumeMounts: - name: templates mountPath: /public/tenant.html subPath: tenant.html - name: templates mountPath: /public/error.html subPath: error.html - name: templates mountPath: /public/res/tenant.css subPath: tenant.css - name: templates mountPath: /public/res/next-btn.svg subPath: next-btn.svg

  
  

• Restart the AUTHENTICATION service.
