Serverless Function MS SQL database API

Overview

This sample provides a Serverless Function configured as an API endpoint for communication with the MS SQL database that you can find in the database-mssql folder. You can also configure the API endpoint to use the database example provided in the database-azure-mssql folder. The deployment.yaml defines the Function definition as well as an APIRule to expose the Function without authentication. The Deployment contains the following parameters for the database-mssql example that you can configure to modify the default options:

Parameter Value
database DemoDB
host mssql.dev.svc.cluster.local
password Yukon900
username sa

Note: If you use the database-azure-mssql example, remove the parameters provided by the Function and use the ServiceInstance instead.

This sample demonstrates how to:

  • Create a development Namespace in the Kyma runtime.
  • Deploy a Serverless Function and an APIRule.

Prerequisites

  • SAP BTP, Kyma runtime instance
  • kubectl configured to use the KUBECONFIG file downloaded from the Kyma runtime

Steps

Deploy the Function

  1. Create a new dev Namespace:

    kubectl create namespace dev
kubectl label namespaces dev istio-injection=enabled

  2. Apply the Deployment:

    kubectl -n dev apply -f ./k8s/deployment.yaml

  3. Verify that the Function is up and running:

    kubectl -n dev get function api-mssql-function

  4. Use the APIRule:

  • https://api-mssql-function.{cluster-domain}/orders
  • https://api-mssql-function.{cluster-domain}/orders/10000001
