Introduction

Application which sends an e-mail at regular intervals. An Gmail App password needs to be created: https://myaccount.google.com/security. The application uses the password to send an e-mail to a recipient. The application is available as a Docker container to run locally or in the cloud as an Azure Function App. The whole infrastructure is managed by Terraform. CICD is done using Azure DevOps.
