Can Azure Storage Resources (Blobs / Tables) be accessed from Containers?

[TurtleBeach]

I have a Windows nanoserver container running a spring-boot application that accesses azure table storage from within a spring-boot CommandLineRunner. The container runs fine locally (Docker / Win10 Pro). When I deploy to a container instance, a StorageException is thrown at the point that an attempt is made to retrieve a DynamicTableEntity from a table. The connection to the storage account and the table appear to succeed, but the retrieve operation fails. The Tomcat server is running and responsive (I catch the exception and prepare basic error information to be returned by servlets that manage requests). I have been unable to find any examples or definitive statements about using the Java Azure storage libraries in containers, so I would like to know if there are any restrictions.
Thanks.

Further to my earlier post, the storage exception is apparently being thrown due to an "unknown host". See logs below. The CommandLineRunner: entries reflect logging from my code - storage account credentials are parsed and a reference to the table obtained without error (both of course using HTTPS encapsulated by version 8 of Azure Java storage libraries). When testing the container on a local machine, the table is accessible.

This is extremely frustrating - it takes 4-5 hours to upload an image to the repository, and debugging options are limited in the cloud.
I would greatly appreciate any insights into why table access is not working.
