Docker Monkey Dance!

Docker CF-BOSH release

https://github.com/cf-platform-eng/docker-boshrelease

• Multiple Docker containers can be orchestrated into multiple vms

• Your choice of IaaS: AWS, OpenStack, VSphere, VCHS, CloudStack or GCE

• Containers self-healing• Container dependencies• Virtual machines self-healing• Host volumes can be bound to Docker containers• Resize data disks on-the-fly without losing data• Route container’s output to a remote syslog

Awesomeness!
