MongoDB in Azure Container Apps

Question

Hello, I need to run MongoDB as an Azure Container App, and I have a couple questions.

How do I ensure that the data doesn't disappear if the container goes down? I saw people saying to connect a file storage system, but if that is the answer does anyone have some examples/tutorials on how to do so?

If I have other containers running in Azure, how do I allow them to connect with the MongoDB container?

Thanks for the help!

Hi @Rishab Mehta,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
To run MongoDB as an Azure Container App while ensuring data persistence and enabling connectivity with other containers, follow these steps:

1)Ensuring Data Persistence:

• Create an Azure Storage Account and a file share.
• Mount the Azure File Share to your MongoDB container to store data outside the container, ensuring persistence even if the container restarts or crashes.
• Ensure your MongoDB configuration points to the mounted volume for data storage (e.g., /data/db).

2)Connecting Other Containers to MongoDB:

• Deploy your MongoDB container and other containers within the same Azure Container App environment or virtual network to allow them to communicate.
• Ensure that the MongoDB container exposes the default port (27017) so that other containers can connect to it.
• Use the MongoDB container's service name in connection strings from other containers. Azure Container Apps supports built-in service discovery for easy connection using the container name.
