Watchtower not working on Synology DSM 6.0.x as a Docker container

When installing the standard Watchtower container onto DSM 6.0 with Docker, I ran into 2 issues which caused the container not to run and constantly restart itself (see container logs for the error messages):

1. Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
2. Error response from daemon: client is newer than server (client API version: 1.24, server API version: 1.23

Both issues have a solution. First being that an older docker image has to be used, second being that DSM UI somewhere filters out a file mapping when creating the container.

Fix for issue 1: Create a symlink

sudo ln -s /var/run/docker.sock /volume1/docker/docker.sock

Fix for issue 2: Create a new docker container

sudo docker run -d --name watchtower-new -v /volume1/docker/docker.sock:/var/run/docker.sock centurylink/watchtower --interval 82800 --cleanup

Thanks to these links for finding a solution
