Migration precheck

Assumptions:

  • Only the participants can execute a precheck.
  • Precheck is executed before the migration, if it fail the migration will be not executed.
  • User needs to receive the result of the precheck.
  • Acm-runtime needs to handle the precheck fail in a different way it handles migration fail.

Solution 1: create a new flow for migration-precheck.

User can send the action migration-precheck POST. The user can do the action migration POST after that. The migration flow is still backwards-compatible.

  • User send migration-precheck action
  • Acm-runtime set the instance in "MIGRATING-PRECHECK" deployState
  • Acm-runtime sends migration-precheck message to participants
  • Participant receives migration-precheck message and executes the precheck and sends the result
  • Acm-runtime receives precheck-result messages from all participants
  • Acm-runtime shows this result into the stateChangeResult (deployState will be in "DEPLOYED" state)
