Customs Halls are approval workflows. Used as gateways to Harbors they enforce approval rules before containers can be deployed to a Harbor.   Customs Halls exist in 3 forms:


Manual Approval 
The approval workflow is triggered on manual email approval from one or more designated approvers.

Automated Approval
The approval workflow is triggered on the success of an automated test or process.

Approval Lookup
The approval workflow is triggered on the existence of a change request or service desk ticket.
