Best practices when adding files to docker image used in azure batch?

Question

I'm trying to allow for the use of docker images in our azure ecosystem, possibly with the ability to ADD and COPY files inside of the docker image to be used inside of the Azure Batch Task. When I try to ADD files I can't access (or see) them inside of the task or pool, even though when I run the image locally I can see them. Should I just be using the batch resources to pull in the files instead? I'm not sure what the best practice is here, there is no documentation about it.

Hey Tiffany Seale

Thats an great question and thanks for posting the question and QandA platform,

It's crucial to make sure that your approach aligns with best practices.lemme drop you a few pointers

so when working with Docker images in Azure Batch, consider storing necessary files in Azure Batch File Shares or Azure Storage instead of adding them directly to the Docker image. You can then mount these shares during task execution, ensuring efficient file management. Avoid relying on files added during the Docker image build, and use tools like azcopy or wget within your Batch tasks to download files as needed.

For large files, Azure Storage is a good option. You can download the required files from Azure Storage within your Batch tasks.

If your files are in Azure Blob Storage, you can use tools like BlobFuse to mount blobs as directories inside your Docker container.

If this helps kindly accept the answer thanks much.
