Systemd is used to setup a static route and Debian 8.1 or later is recommended as the host distribution. Others probably work, but haven't been tested.
### Step 1 — Setup IPv6 on the Host Machine
The tutorial uses a free tunnel from [tunnelbroker.net](https://tunnelbroker.net/) to get a /64 and /48 prefix allocated to me. The tunnel endpoint is less then 3 ms away from Digital Ocean's San Francisco datacenter.

If this doesn't work, figure it out. It may be necessary to add an firewall rule to allow IP protocol 41 through the firewall.
### Step 2 — Setup the systemd Unit File
Copy the systemd init file from the docker-openvpn /init directory of the repository and install into `/etc/systemd/system/docker-openvpn.conf`
### Step 2 — Update Docker's Init To Enable IPv6 Support
Copy the system's existing docker file and append the `--ipv6` argument to the end of the command line:
sed -e 's:^\(ExecStart.*\):\1 --ipv6:' /lib/systemd/system/docker.service | tee /etc/systemd/system/docker.service
Reload the daemon and restart docker so that it takes affect:
systemctl daemon-reload && systemctl restart docker.service
### Step 3 — Setup the systemd Unit File
Copy the systemd init file from the docker-openvpn /init directory of the repository and install into `/etc/systemd/system/docker-openvpn.service`
curl -o /etc/systemd/system/docker-openvpn.service https://raw.githubusercontent.com/kylemanna/docker-openvpn/dev/init/docker-openvpn.service
Edit the file, replace `IP6_PREFIX` value with the value of your /64 prefix.
vi /etc/systemd/system/docker-openvpn.service
Finally, reload systemd so the changes take affect:
systemctl daemon-reload
### Step 3 — Start OpenVPN
### Step 4 — Start OpenVPN
Ensure that OpenVPN has been initialized and configured as described in the top level `README.md`.
