Adding Docker Plugin

Get status of VMs

vagrant status

SSH into your nodes and install flocker docker plugin.

vagrant ssh node1
sudo su
cd credentials/
/opt/flocker/bin/flocker-ca create-api-certificate plugin
cp plugin.* /etc/flocker
yum install -y clusterhq-flocker-docker-plugin
systemctl enable flocker-docker-plugin
systemctl start flocker-docker-plugin
systemctl restart flocker-docker-plugin

Exit from that node

exit
exit

Node 2

vagrant ssh node2
sudo su
cd /etc/flocker/

The password for the next command (scp) is vagrant

scp root@172.16.255.250:/home/vagrant/credentials/plugin* .
yum install -y clusterhq-flocker-docker-plugin
systemctl enable flocker-docker-plugin
systemctl start flocker-docker-plugin
systemctl restart flocker-docker-plugin

Exit out of node2

exit
exit

Test our your local flocker cluster

vagrant ssh node1
docker run -v apples:/data --volume-driver flocker busybox sh -c "echo hello > /data/file.txt"
docker run -v apples:/data --volume-driver flocker busybox sh -c "cat /data/file.txt"

Also, if you have uft-flocker-tools installed locally, it works!

uft-flocker-volumes --control-service=172.16.255.250 list
