Need to scale your app? Put it in a container. Need more resiliency? Put it in a container. Code starting to smell? Put it in a container. Want some lunch? Put it in a container.
Okay. Containerization is pretty great, but once you start dealing with saving data and/or files you realize you need to add volumes to the mix. Docker volumes provide access to external resources, such as storage, in a way that seems local to the container. Mapping a local drive on the host to the container is as simple as adding a line or two to a docker-compose.yml file.
But what happens when you move to the cloud? Specifically, let’s talk about Azure. If you’ve got files to save in Azure, you’re probably using Azure Storage. Azure Storage provides a number of great features at a very competitive price, but how can we access those files within a container running in an Azure App Service? Read on to learn.
