For my integration tests, I am running an sftp server (atmoz/sftp) via dockertest. Currently I am mounting a directory (with sub-folders + files)

    fp, err := filepath.Abs("./testfixtures/upload")
        if err != nil {
            return nil, fmt.Errorf("Could not get absolute path: %w", err)
        }
    
        options := &dockertest.RunOptions{
            Repository: "atmoz/sftp",
            Tag:        "latest",
            Env: []string{
                "SFTP_USERS=foo:123:1001:1001",
            },
            Mounts: []string{
                fmt.Sprintf("%s/:/home/foo/upload", fp),
            },
        }
    
        // Run the container
        resource, err := pool.RunWithOptions(options)
        if err != nil {
            return nil, fmt.Errorf("Could not start resource: %w", err)
        }

When connecting to the server in the code, I am able to access the read the files – but NOT rename a file which is a requirement

    service_test.go:57: failed to process: unable to rename file - G0731626.cdf: sftp: "Failure" (SSH_FX_FAILURE)

I get that this is related to the file mode 493 for the file named G0731626_20240502_022401SB_000001.cdf. But not sure how to resolve this? I can’t change the mode or owner of the local directory as this will prevent the initial mounting.

Any help would be appreciated
