A simple calculator that parses the querry string and responds with the solved calculation.

The service is available at : https://futuricetic-calculator.azurewebsites.net/

A base64 encoded expresssion can be sent as follows:

expression to be solved: 2 * (23/(3 * 3))- 23 * (2 * 3)

base64encoded string : MiAqICgyMy8oMyozKSktIDIzICogKDIqMyk=

Work flow

The repository contains three main branches 'main', 'develop', and 'release'. 'Develop' is the default branch and branch where the source code of HEAD always reflects a state with the latest delivered development changes for the next release. When the source code in the develop branch reaches a stable point and is ready to be released, all of the changes should be merged back into 'main'. The 'main' branch is where the source code of HEAD always reflects a production-ready state. To deploy the new release the 'main' branch should be merged with the 'release' branch which will trigger the deployment procedure from the creation of a Docker container and then pushing it to the Azure container registry (ACR). An Azure App Service uses the container from ACR via webhook and the new release is deployed.

Deploying the container on Aure app service (with continuous deployment)

• Create a 'Resource-group' at Azure (To manage all the resources).
• Create Azure Container Registry (ACR) to push container images to this registry from Github.
• Create registry access keys at ACR and add them in the Github repository settings(Github secrets) and use them in the Github-Actions-Flow so that containers can be pushed to ACR. (see my-futuricetic-calculator/.github/workflows/main.yml)
• Create an 'App-Service' at Azure, assign it to the previously created resource group, use Docker for publishing by choosing 'Docker' in the publish option.
• After app service is successfully created, navigate to 'App-Service > Settings > Container Settings', here choose 'Azure Container Registry' as the image source, Select the previously created registry, then chose the image name and tag then save settings.
• For Continous deployment, turn on the option 'Continous deployment' by navigating to 'App-Service > Settings > Container Settings', Copy the webhook URL, then navigate to 'Container registry > Services > Webhooks', Then add a webhook here, give it a name and paste the Webhook URL link here. This will create a webhook and whenever a new container image is pushed to ACR it will be deployed to the APP-service.
