Using Puppet stdlib in TripleO is risky because it exposes deployments to dependency cycles in the catalog. We should rather use native functions to make orchestrations, like ordering and dependencies management. This patch: - removes usage of stages from stdlib - use ordering to make sure we run pre rules before post - use ordering to make sure we start all Services in catalog before post rules. It ensure that we don't drop all traffic before starting the services, which could lead to services errors (e.g. trying to reach database or amqp) Change-Id: Iec4705d6b785a40ccf6f43809b94b726ccd47fef Closes-Bug: #1643575

|

# tripleo.<service name with underscores>.firewall_rules:
|

# '300 allow custom application 1':

# dport: 999
