[openstack-dev] [Heat] stack-update with existing parameters
TL;DR Is there any reason why stack-update doesn¹t reuse the existing
parameters when I extend my stack definition with a resource that uses
them?
I have created a stack from the hello_world.yaml template
(https://github.com/openstack/heat-templates/blob/master/hot/hello_world.ya
ml)
It has the following parameters keyname, image, flavor, admin_pass,
db_port.
heat stack-create hello_world -P
key_name=test_keypair;image=test_image_cirros;flavor=m1.test_heat;admin_pa
ss=Openst1 -f hello_world.yaml
Then I have added one more nova server resource with new name(server1),
rest all the details are untouched.
I get the following when I use this new template without mentioning any of
the parameter value.
heat --debug stack-update hello_world -f hello_world_modified.yaml
On debugging it throws the below exception.
The resource was found
athttp://localhost:8004/v1/7faee9dd37074d3e8896957dc4a52e22/stacks/hello_wo
rld/85a0bc2c-1a20-45c4-a8a9-7be727db6a6d; you should be redirected

When I mention all the parameters then it updates the stack properly
heat --debug stack-update hello_world -P
key_name=test_keypair;image=test_image_cirros;flavor=m1.test_heat;admin_pa
ss=Openst1 -f hello_world_modified.yaml
Any reason why I can¹t reuse the existing parameters during the
stack-update if I don¹t want to specify them again?

Hey Dimitri,
There is an open bug for this feature:

Hey Dimitri,
There is an open bug for this feature:
https://bugs.launchpad.net/heat/+bug/1224828
and it seems to be being worked on.
In fact it's complete, and you can now use the -x (or --existing) flag
to do this on the latest master of Heat (i.e. it will be available in
Juno) and the latest release of python-heatclient.
cheers,
Zane.
