400 Client Error: Bad Request

Hi,
I am interested to use docker-sync. I have followed instruction to run it.
Unfortunately I get an error when I run it. Here is the error I get.
Traceback (most recent call last):

docker.errors.APIError: 400 Client Error: Bad Request ("client version 1.8 is too old. Minimum supported API version is 1.23, please upgrade your client to a newer version")

I appreciate if you could guide me about it.

You'll need to upgrade docker-py to work with the newer version of the Docker server.

Thanks for quick response. I upgraded docker-py to 1.8.0, and Docker server is latest version, but it still giving the same error.

With docker client 1.8 you highest supported API version is 1.20 (see https://docs.docker.com/engine/reference/api/docker_remote_api/). You are obviously connecting to a docker server of version 1.11.x which supports API version 1.23, and seems to be quite strict on not supporting older versions. You need docker client version 1.11.x

Thanks for information. It now runs perfectly, nice work.
Let's say I create a container file as 00-hosts.yaml available as example. The first run is fine, it filters all unwanted containers. But it says "ports are different" and remove the container when I run it for the second time with exactly the same file which does not have any different port defined. Shouldn't it keep the container which is made from 00-hosts.yaml file?

Sorry my mistake, it does not remove it if same. Awesome. Thanks
