You can run PX-Developer with docker-compose to create a storage cluster for containers, as follows:

# git clone https://github.com/portworx/px-dev.git
# cd px-dev/quick-start
# docker-compose run portworx -daemon -k etcd://myetc.company.com:4001 -c MY_CLUSTER_ID -s /dev/nbd1 -s /dev/nbd2

OR, if you have a custom px configuration file at /etc/pwx/config.json, you can start PX-Developer as follows:

# docker-compose up -d

You now have a scale-out storage cluster for containers. To continue, refer to the resources listed in Get Started with PX-Developer.
