      networks:
      - port: {get_resource: s_port}
      - port: {get_resource: s_port2}
      name: testss
  s_port2:

3. the stack update failed, because the s2 create failed: port2 still in use
4. finally, we can find that port2 detached from s1

Because there is no dependence between s1 and s2, so they update in parallel. I think add the dependence to s2 will fix this problem.

It seems this is not allowed in heat.
The s_port2 is fixed in the first stack creation.

i meet the bug before..
when i try to update..i found my s_port2 is detached from s1...(that is OK)..
and i try to use nova interface-attach --port-id to add this port to s2..
nova give me a HTTP error(500)...

Hi zhaozhilong ,

Could you please explain this bug, In Step 1: 2 ports are assigned from same network. Is this possible? In real scenario it never be assign same 2 port from same network.

Which version of openstack did you face this issue?

[Pete Birley (petebirley)]

This is also affecting my deployment, Trove, Murano, and Manila are now all failing, I am running the latest heat from git, all was working well with Liberty RDO packages, and head from approx 1 month ago.

[pawnesh kumar (pawnesh.kumar)]

i am not able to reproduce this , in newton release
