Changing Labels on aws docker engine.md

First ssh into the node you want to add lable to

docker-machine ssh aws-node

Depending on wheather the machine is using upstart or systemd you will need to modify a config file:

systemd:

sudo vim /etc/systemd/system/docker.service

edit the line starting ExecStart to add label

ExecStart=/usr/bin/docker daemon -H .... --label provider=amazonec2 **--label your=newlabel** --cluster-store=consul://ip:8500 --cluster-advertise=eth0:0 
MountFlags=slave

reload demon units

sudo systemctl daemon-reload

upstart:

echo "DOCKER_OPTS=\$DOCKER_OPTS --label your=newlabel" | sudo tee -a /etc/default/docker

Restart the docker engine

sudo service docker restart

Restart the containers

export DOCKER_HOST=unix:///var/run/docker.sock
sudo docker start $(sudo docker ps -aq)

check the containers are up

sudo docker ps

check the docker entgine info

sudo docker info
