BTSYNC - revisited, and conquered
I got this shit it working!
My own personal, client-encrypted, always online, secure storage.
plase read my original btsync post for some context.
My issues arose because I did not know that docker tried to resolve DNS with its host. This is ubuntu, that was terrible. I configured the entire docker deamon to use some external DNS, and suddenly, it works. EXACTLY as I had hoped.
