Azure Container Instances (ACI) and Secrets - Using Secure Environment Variables

This article explains how to use secure environment variables (secureValue) in Azure Container Instances (ACI) to protect sensitive data like connection strings from being visible in the Azure Portal or API responses. It covers security considerations, noting that while values are hidden outside the container, they remain accessible inside. The post demonstrates two methods for creating secure environment variables: using Azure CLI directly and via YAML definition files, with a sample YAML configuration provided. Aimed at developers deploying Docker containers in Azure, it emphasizes best practices for handling secrets in cloud environments.
