Hello @gra_in_aus, thanks for using SAS Communities.
In this blog SAS Viya on Microsoft Azure: Three Ways to Import your Data files, there are steps describing a few ways to import your data files in SAS Viya up and running on Microsoft Azure.
If you are thinking to use remote shares to CIFS mount, in order for the container to 'see' the shares and, for example, configure SAS Studio to use the shares, the container will need to have the mounts configured first.
This step is specific to docker and not SAS Studio.
See the following information on defining cifs and nfs shares that can be used within the container:

Please let me know if this is answering to your question. Thanks.
