Well, we need a database service because we cannot use a local database server when we deploy our application live and also to persist data. We need to create a MongoDB database service to fix this error and use the connection URI it provides for us. We are getting this error because Cloud Foundry cannot recognize or see any connection URI for our MongoDB database. If you've not noticed already, when we push the application initially, it throws an error that looks like this: You can deploy to the application by running the following command: Let's test this theory by deploying our application on Cloud Foundry. We need a database service to help us manage the database when it's deployed live. While this works locally, we cannot use the local MongoDB server when we deploy our application on Cloud Foundry. If you run the application by running yarn start on your local machine and with a local MongoDB server, you'll get the following in your browser when you navigate to localhost:8080or the PORT number you provided in the. MONGO_URI = MongoDB service connection URI (this will be provided when we create a Cloud Foundry database service).ĬLOUDINARY_CLOUD_NAME = This will be available on your Cloudinary dashboard after registration.ĬLOUDINARY_API_KEY = This will be available on your Cloudinary dashboard after registration.ĬLOUDINARY_API_SECRET = This will be available on your Cloudinary dashboard after registration. NODE_ENV = The current deployment environment, i.e development or production. Run the following command to clone the application to your machine:Įnter fullscreen mode Exit fullscreen mode To get started, we have to clone our application from Github and install its dependencies on our machine. MongoDB handles the storing of the image urls that are used to display the images on the client-side. The server-side of the application is written in Node.js.Ĭloudinary handles the storing of images that are uploaded. The client-side of the application is written with EJS. (I'll be using anynines for the sake of this tutorial).Ī Cloudinary account for storing images that'll be uploaded (API key and API Secret).īasic Knowledge MongoDB, Node.js and Cloud Foundry We will also make a few changes to our deployed application and re-deploy our application to see how fast Cloud Foundry updates our application in the browser.Īny Cloud Foundry distribution account. I'll demonstrate how to use a database service we will create in our application to read, write data to our application and also persist data. In this tutorial, we will be deploying a full stack application on Cloud Foundry with a Node.js backend and a MongoDB database service. I also gave an introduction to what services are in Cloud Foundry and how to get started with them. To allow the application to use the destination you have just configured, you need to bind instances of the destination and the XSUAA services to your application.In the second part of this tutorial, I demonstrated how to deploy a Node.js application on Cloud Foundry, make a few changes to the deployed application to see how fast Cloud Foundry updates our application in the browser and finally, bind our application to a database service. This will make the fields User and Password appear.Įnter here the credentials of a technical user for your SAP S/4HANA Cloud system. If you use an SAP S/4HANA Cloud system, enter the system URL in the URL field and choose BasicAuthentication as the authentication type. If you use the business partner mock server, for URL enter the URL that you have saved from the previous step and use NoAuthentication for Authentication. On the page that opens, click New Destination and fill in the details below.įor Name, choose a name that describes your system. In the menu bar on the left, there should be a section Connectivity with an entry called Destinations. Next, navigate to your respective subaccount (in case of a trial account it should be called trial). Start by opening the Cloud Cockpit in your browser and logging in. Now that you have deployed your application, you need to configure a destination in the Cloud Cockpit so that it can be used by your application. When the server has been pushed successfully, cf CLI will output the route where the server can be reached.Ĭopy this route, as you will need it in the next step. Make sure that your mock server and Node.js are up to date.
