Everything works, except that the files and directories defaults to permission 0777, always. When I tried to manually mount within the container, I could customise dirmode and filemode, meaning that this change should be possible. Reading the source code confirms it - dirmode=0777 and filemode=0777 seem hardcoded. What you expected to happen: Being able to supply dirmode and filemode to the mount. e.g. How to reproduce it (as minimally and precisely as possible): N/A. This is a feature request.

Anything else do we need to know: N/A
This is a big requirement, using an azure file volume for postgresql for instance fails due to permissions as initdb tries to change the permissions to be less restrictive but is unable to.
Evaluating compatibility between a certain setup of a volume mount and an arbitrary piece of software would be the responsibility of the integrator, wouldn't it? It seems a big requirement for K8s itself to have to ensure PostgreSQL can do what it wants. An integrator who tries to use Azure File Storage for PostgreSQL should know better to mount with the correct permission.
The point is that you cannot mount with permissions, they're hard coded to 0777.
Ah. Yeah. Sorry for misunderstanding the comment above. Let's say it is an "important" requirement :)

I have a for this, use mount options in storage class, below is an example:
Has this change made it into any release yet? I can't seem to find it... Or was the issue resolved in some other way? I'm facing the issue you originally reported, i.e. using a pod volume to an azureFile, and it always mounting with filemode and dirmode of 0755... and I need it to be 0777. Is there a workaround? TIA.
azure file mountOptions feature is available from v1.8.5, here is the example :
Thanks -- I was still having trouble until I the storageClassName: "" to the claim... then realized I was hitting issue which I can avoid by setting storageClassName: "default" to both the pv and pvc, and now everything works. Thanks again!
