too new API version

[KorbenDev]

When I run the alias/docker command I get the following error message:
Error response from daemon: client version 1.40 is too new. Maximum supported API version is 1.39

Running on a Synology NAS. Sorry, quiet a noob...

One workaround is to run with -e DOCKER_API_VERSION=1.39, e.g:
docker run -e DOCKER_API_VERSION=1.39 --rm -i -v /var/run/docker.sock:/var/run/docker.sock nexdrew/rekcod <container>
