This document discusses managing stateful Docker containers using Cloud Foundry BOSH. It describes how the Docker CF-BOSH release allows multiple Docker containers to be orchestrated across multiple virtual machines. Containers and their dependencies can be self-healing. Host volumes can be bound to Docker containers and data disks can be resized on-the-fly without losing data. The release routes container output to remote syslog. A demo is shown of defining container properties like image, command, ports, and environment variables. Resources listed include the Docker and Shipyard CF-BOSH releases on GitHub and documentation.

5. • 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!
