I finally got the danged thing to work.  Forgot that xfs on cent7 doesn't support the overlay2 d_type dependency.  So, what I did as root was the following.  created 2 ext4 lv's.  moved everything in /var/lib/docker to one and mounted it up on /var/lib/docker.  the other was blank and I mounted it up on /opt/seafile-data.  That got it to start.  The root webpage doesn't have a redirect, so you have to poke around a bit.  http://<your hostname or ip>/accounts/login/

if the d_type thing is your problem, it'll be hanging around in your journald logs.

I haven't necessarily tried to recreate an environment as I have attempted to use an image provided by seafile.

I use docker quite a bit.  It's an intentionally crippled version of containers that forces you to obey certain design patterns.  Sure you CAN get around them, but they exist for a reason.  For sanity's sake, I suggest using docker-compose or some other form of automation to recreate your environments correctly each time.  Puppet or whatnot is also perfectly acceptable.

1St I have not used docker as of yet.
I have been using LXC for over 3 years and with a bit of a learning curve I enjoy it, containers are faster than kvm smaller and easy to move and migrate or duplicate
I use turnkey linux for a few of the prebuilt containers.
a easy inrto is to use Proxmox as a gui to kvm/lxc and after updates you can click install turnkey linux containers
stop by the installfest for a demo or to assist building it and there may be a docker person there also

你们好。

So, I understand that containers are a good thing. I have been trying to install seafile via docker, following the guide found online at seafile's website. However when I attempt to invoke the dock with it utilizing /opt/seafile as the root directory for the instance, I get errors that the dock can't create directories during the initialization. 

At this point I'm ready to give up on trying to use containers and simply install upon the bare metal. Thoughts? Ideas?
Any requests for specific error output will be delivered when I can get back home and get to it from my computer instead of my phone.
