See http://console.opencraft.com/ for a working example, and the README for installation instructions.

Discussions

Reviewers input needed:

• Pylint configuration
  • Which warnings to ignore
  • Max locals & Max branches

TODO - Current PR

• Small nits
• Clearing temporary files & directories
• Use constants for instance & server model status
• Web UI loading indicator
• Integration tests
  • Add an integration test that fully instantiates a sandbox
  • Setup CircleCI to run integration tests
  • Make CircleCI builds reliable (they currently timeout)
• Display a "Please wait" page while DNS are being set for the first time, initially
• Add hostname to /etc/hosts to avoid warning "sudo: unable to resolve host xxxx"
• Add comment for instance statuses, pointing to server status descriptions
• Shorter & updated sandbox names

TODO - Future tasks

• Improve logging management
  • Use custom constants for logging levels
• Switch to OpenStack CLI instead of class
  • Use OS_* variables for OpenStack configuration
  • Use vanilla Ubuntu image from upstream
  • Implementation-agnostic public IP retreival

Suggestions & ideas

• Links to PRs in Web UI & Better PR handling via dedicated model
• Get the build to fail when the ansible run fails (might also require error states for VMs & retries)
• OpenCraft logo & "Powered by"/licensing footer & as a favicon
• Relax regex syntax for configuration variables in PRs
• Better status transition management - state machine?
• Better approach for reboot detection
• Load XBlocks by default
