Controlling Containerized xUML Services (Kubernetes)

You have two options to deploy xUML services as a Kubernetes workload:

1. The PAS Administration offers a deployment wizard (refer to Working With the Deployment Wizard for details).

2. You can also deploy Designer services directly to the deployment target Container (refer to Designer Guide > Service Deployment Details).

xUML services that run in Kubernetes have extended details to manage this type of service.

We recommend using container deployment as the default deloyment target starting with PAS 23.1. For further information see:

• Designer Guide:

  • Service Deployment Details

• Administration Guide:

  • Controlling Containerized xUML Services (Docker)

  • Controlling Containerized xUML Services (Kubernetes)

Using the Workload Details

You can open a details page for each workload. To do so, click on the service name in the list:

Click on a name in the service list to open its details page. The details page shows you the title of the service and some quick actions:

Icon	Description
	Indicates the current state of the service.
	Indicates if logging for Process Mining is enabled or not.
	Starts the service.
	Stops the serivice.
	Restarts the service.

It also contains different collapsable sections:

• Information

• Kubernetes

• Details

• Documentation

• Logs

• History Log

• Persistent State

• Configuration

Information

The Information section contains the main information about the Kubernetes workload:

• Name

• Source is Kubernetes for workloads

• Type

• Created/Updated

• Version

Kubernetes

On top of the Kubernetes section, you find the information about

• API Version: Defines the versioned schema of this representation of a Kubernetes workload.

• Labels: Map of string keys and values that can be used to organize and categorize (scope and select) workloads.

• Annotations: Unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata.

Click Show all to display all available labels or annotations:

Below this information, you can find the two tabs Pod and Networking:

Pod

Tab Pod contains the sections General and Container. The information displayed in the two sections is read-only.

Pod - General

Section General contains common information about the Pod:

To scale the number of replicas, move the position of the slider to the desired number of replicas you want to set. Click Apply:

A pop-up window opens displaying the number of replicas before and after the change. Click Scale to confirm your choice or Cancel to abort:

The new number of replicas is displayed after a refresh of the browser tab:

Pod - Container

Section Container consists of several tabs, one tab for each container. The content of the tabs is the same for all containers and displays the container details:

• Scheduling, Preemption and Eviction about the rules regarding the termination of pods.

If you click the link Ports and Volumes, the container details open in a separate pop-up:

• Ports: Displays a list of all ports exposed in the internal network.

• Volumes: Lists all mounted volumes.

Use the filter on top of each list to search for single ports or volumes.

Networking

Tab Networking gives you an overview on the details of the service mesh. Use the filter to search for a port name:

Details

On top of the Details section, you can find the option Delete Service (refer to Deleting a Service below for further information). The boxes General, Build and Deployment contain read-only information:

The General details contain common information about the compiled .rep file:

The Build details contain information about the workload:

The Deployment details contain information about the deployment:

Below the three sections that contain read-only information, you can find the two tabs Endpoints and Libraries (see below for details):

Endpoints

In tab Endpoints you can find the necessary information regarding the API endpoints of this service:

Column	Description	Possible Values
Name	Name of the registered endpoint.	Any string.
Type	Type of the registered endpoint.	control rest shadow soap ui
URL	Click the URL to copy the secured endpoint to the clipboard. Click the arrow to display the URL of the internal endpoint. Click the URL to copy it to the clipboard.	Any URL.
Test	Use option Open to switch to the interface that allows you to test the application/API. The test interface is available on running services only. The PAS platform features an xUML Runtime API for each service. You can use the interface to obtain information on the states of the service's state machines in general, and to trigger state transitions. Refer to xUML Runtime API Reference for a comprehensive list of all available requests.	-
Interface/Descriptor	Use option Download to download the description (OpenAPI/WSDL) of the service interface. Use option Copy to clipboard to copy the private descriptor URL.	-
API	Use option Import to import the API to Scheer PAS API Management. A wizard will support you in creating the API in API Management. Refer to Creating an API in the API Management Guide for details.	-

Use the filter field to search for a specific endpoint. The content of the filter field is applied to the columns Name and Type:

Click Extended filter to display the extended filter options:

• Type

• Reset Filter

If a filter is applied, the extended filter image changes:

Use option Reset Filter in the main filter window to reset all selected filters. In the filter option window, you can also reset the selection:

Libraries

In tab Libraries you can find a list of all libraries that are used in this service:

Use the filter field to search for a specific library. The content of the filter field is applied to the column Name only:

Deleting a Service

If you want to delete a containerized xUML service, click Delete Service on top of the Details section:

Please note, that the deletion of a service has several consequences:

• The service container (deployment) will be removed from the current system.

• The registered routes are purged.

• Persisted data stored in this service will be removed.

Option Delete is only enabled if you insert the correct service name:

Documentation

Open the Documentation section to display the documentation of the xUML service:

Use the list Select Document to choose the documentation you want to see. The list contains:

• The documentation of the xUML service itself (if it is a service that has been created in the Designer, you will see the content of field Description from the service details page).

• The documentation of the libraries that are used in the service.

Logs

In section Logs you can change the log level. Refer to Changing the Log Level of a Workload for detailed information.

Use Open Service Logs for direct access to the service logs and Open Process Logs for direct access to the transaction logs. The Log Analyzer will open where you can inspect the corresponding logs. Refer to Showing Logs of a Containerized xUML Service (Kubernetes) and Analyzing Platform Logs for further information.

History Log

In the History Log section you can inspect the service history. Refer to Showing Logs of a Containerized xUML Service (Kubernetes) for detailed information.

Persistent State

In section Persistent State you can manage persistent state objects. Refer to Persistent States of Containerized xUML Services (Kubernetes) for detailed information.

Configuration

In the Configuration section you can change the settings of an xUML service. Refer to Adapting the Configuration of Containerized xUML Services (Kubernetes) for detailed information.
