In theory, this should be possible if you can ensure that there is network connectivity between the k8s cluster and the shared folder. It's important to make sure k8s (linkerd) is also configured to accept SMB traffic. The port number you specified will NOT be taken into account, it's only used for FTP communication.

Hello @Mathias Dahl ,

I managed to configure FTP on azure storage using IIS on WMS server. will share detailed document how i did not.

Now while checking document. I dont get any error but the document does not store on location.

on checking logs i am getting error

Can you suggest please

Do you know that the Kubernetes cluster can reach the FTP server? If yes, how do you know that? How does the basic data of your Docman repository look like?

Thanks!

This is a bit strange. It looks like there is an error when our code tries to close the FTP input stream:

  com.ifsworld.docman.projection.util.AutoCloseFtpInputStream.close(AutoCloseFtpInputStream.java:20)

That calls

 org.apache.commons.io.input.AutoCloseInputStream.close(AutoCloseInputStream.java:64)

62   @Override

63    public void close() throws IOException {

64        in.close();

65        in = ClosedInputStream.CLOSED_INPUT_STREAM;

66    }
    
Which throws a null pointer exception. This suggests the stream is null ("in" above). Why would it be null if there is a successful FTP connection? Perhaps something closed it before? Either our own code has closed the connection or some other code did it...

We could try to add a check in our Java code, to see if the stream is not null before we close it. Then again, we might not be able to recreate this internally since, for us, FTP is working. So we would do that fix "blindly" (fixing something without being able to recreate the problem), which is never good.

I'll discuss this internally and see if we can come up with some theory.
 

Thanks @Mathias Dahl ,

Look forward. seems I am there but not there :(

Hi @Mathias Dahl 

I saw the same error in another customer (22R2 remote deployed) when they try to view a document which is saved in FTP. You cannot see any errors in the client during upload but you get a server error when you try to view the file. Below error is in the ODATA logs which is the same error as above.

I didn't receive feedback regarding FTP logs and the connectivity between k8s cluster and FTP server but since above log shows FTP code 220 (220 code is sent in response to a new user connecting to the FTP server to indicate that the server is ready for the new client) I am not sure it is due to a connectivity problem.

Check the FTP server logs to see how the communication looks like. In the server I use I can see every command, the whole interaction actually. 

Stupid question: does the file exist?
