States

This section is an explanation of the various states that are used in NetOrca objects.

Change Instance state

Change instances have the following possible states

  1. PENDING: The CI has been requested and is not yet approved by the Service Owner
  2. APPROVED: The CI has been approved, the declaration requested in this CI is now the active declaration for the SI
  3. COMPLETED: The CI has been completed, this indicates to the user that the requested declaration in this CI has now been applied to the infrastructure
  4. REJECTED: the PENDING CI has been REJECTED, this could be due to validation or incompatibility. The Consumer must change the declaration for this SI on next push.
  5. ERRORED: an APPROVED CI cannot be implemented onto the infrastructure. This is a rare occurance as validated CI's should be able to be completed by the ServiceOwner. This is an indication of a broken process.
