@Neha Sankhe Thanks for reaching out. The specific container engine used internally by Azure Container Apps is not explicitly mentioned in any available documentation and no way to determine it.
It’s important to note that the container engine used internally by a platform like Azure Container Apps is typically abstracted away from the user. The platform takes care of running the containers, and users don’t need to interact with the container engine directly. Instead, users can focus on building and deploying their applications.
do let me know incase of further queries, I would be happy to assist you.
