Live Updates (in development)

API

This is the current design of the API

• Command to set a password
  • sg -setpass password -password currentpass
  • so commands can be run securely via chef / puppet or SSH (password loaded into memory at sg boot)
  • password will also be used for administration and statistics service
• Command option to migrate a running spider gazelle to a new version
  • sg -upgrade name -password currentpass

Behind the scenes

• setpass
  • setpass uses scrypt to create a password file that can be distributed with the application
• upgrade? Needs more thought
  • Stop binding accepting sockets, pass binding over a pipe, new process starts accepting
  • how to deal with service supervisors? They may spawn a new process when the original shuts-down
  • Needs to also work where there is no supervisor
