Create a stack and validate it

3. check and parse withproperty schema.

class

4. if func. in side, call function of the version (pike)

5. got resource object

2. get a class or files for that resource

1. search mapping implements base on type

6. build dependenices for resource

From a resource object to actually create

1. ask worker to `check_resource`

2. call with `create_convergence`

3. create with `handle_create`

4. use service client with context from heat to triger createlike: self.sled_dogs().create(*kwargs)

5. mark as CREATE COMPLETE.All resource go to `CREATE COMPLETE`

I need a new resource type

def resource_mapping(): return { 'OS::Sled::Dog': SledDog }

Or in environment file:

● openstack stack event show <stack> <resource> <event>● openstack stack resource show <stack> <resource>● report a bug! https://bugs.launchpad.net/heat● chat on irc #heat or join our meeting● A reset botton?

And if anything went wrong

● openstack stack abandon <stack>● openstack stack export <stack>● openstack stack adopt --adopt-file <adopt-file> <stack-name>● openstack stack snapshot create <stack>● openstack stack snapshot restore <stack> <snapshot>

A Reset Button

● Consider backwards● With Unittest● synchronize● review! review! review!

Hacking rules

● Python 3.5 support● Neutron Segment resource for routed networks● Neutron VLAN trunk ports (802.1Q)● External custom resources managed by Mistral workflows● New intrinsic functions: make_url, list_concat_unique● Internal architecture improvements● Stable attribute values (no live lookup) in convergence● Memory & performance improvement for convergence● Reliability improvements for large stacks● [Preview] Optionally compare to actual state of resources during updates
