//Enable the remote API on a new socket
Create a file called /etc/systemd/system/docker-tcp.socket to make Docker available on a TCP socket on port 2375.

[Unit]
Description=Docker Socket for the API

[Socket]
ListenStream=2375
BindIPv6Only=both
Service=docker.service

[Install]
WantedBy=sockets.target

Then enable this new socket:

systemctl enable docker-tcp.socket
systemctl stop docker
systemctl start docker-tcp.socket
systemctl start docker

Test that it's working:
docker -H tcp://127.0.0.1:2375 ps

//Install portainer run on 9999
docker run -d -p 9999:9000 -v "/var/run/docker.sock:/var/run/docker.sock" portainer/portainer

//Switch channel
You can switch machines between channels by creating /etc/coreos/update.conf:
GROUP=alpha

//Restart update engine
sudo systemctl restart update-enginesudo

//Manual update
sudo update_engine_client -update

//Start service
