We created a bunch of custom resources for use in global environments. They
work just fine if they are registered from a user's environment (specified
using -e) using resource_registry, both for stack-create and stack-delete. If
the same environment is copied to /etc/heat/environment.d stack creation will
continue to work. stack-delete depends on the continued availability of the
global environment used to create the stack, though. If the global environment
is removed before stack-delete the stack will be remain stuck in state
DELETE_IN_PROGRESS indefinitely. Additionally, stack-abandon will result in an
error message:
$ heat stack-abandon test_delete
ERROR: Unknown resource Type : sys11::bootstrap
Recovery from the error condition is possible through restoring the missing
environment and issuing another stack-delete.
A minimum example template, environment and costum resource to reproduce the
problem we observed is attached. We ran into this problem with the stable/juno
version of heat-engine (Ubuntu Package version 2014.2.1-0ubuntu2~c).
Steps to reproduce with user environment (working):
1. tar -C /tmp -xf test_global_env.tar
2. heat stack-create -e /tmp/test_global_env/env.yaml -f /tmp/test_global_env/test.yaml -P key_name=<nova key name> test_delete
3. heat stack-delete test_delete # Works fine.
2. heat stack-create -e /tmp/test_global_env/env.yaml -f /tmp/test_global_env/test.yaml -P key_name=<nova key name> test_delete
3. heat stack-abandon test_delete # Works fine.
Steps to reproduce with global environment (breaks upon stack-delete):
1. tar -C /tmp -xf test_global_env.tar # on the machine where heat-engine is running.
2. cp /tmp/test_global_env/env.yaml /etc/heat/environment.d/
3. service heat-engine restart
4. heat stack-create -f /tmp/test_global_env/test.yaml -P key_name=<nova key name> test_delete
5. rm /etc/heat/environment.d/env.yaml
6. service heat-engine restart
7. heat stack-delete test_delete # Stack gets stuck in state DELETE_IN_PROGRESS.
8. heat stack-abandon test_delete # Results in the error message shown above.
9. cp /tmp/test_global_env/env.yaml /etc/heat/environment.d/
10. service heat-engine restart
11. heat stack-delete test_delete # Will work now.
