Hi,
I am testing stratos 3.0.0 incubating in our environments however i have
seen some issues. On fresh start it could open new vm or close vm on
openstack with min app instance or max app instance information. After
starting to stratos instances if i change the min app instance information
in configuration file
(apache-stratos-cc-3.0.0-incubating/repository/deployment/server/services/test.xml)
it is not terminate the vm. When i check the logs i have realized that
there is an issue AutoscaleDeciderCallable.java. In this file it is getting
serviceConfig object with serviceConfig =
appDomainContext.getServiceConfig();. On the other hand
AppNodeSanityCheckCallable getting serviceConfig like
AutoscalerTaskDSHolder.getInstance().getWholeLoadBalancerConfig().getServiceConfig(this.domain,
this.subDomain); ServiceConfig object on AutoscaleDeciderCallable is
getting old deployment information but the other one is correct. When i
have changed this code on AutoscaleDeciderCallable it has started to
terminate instance. But this time i have get error on Cloud Controller.
You could see the logs at the below. Do you have any suggestion about the
problem. By the way if you wish to commit AutoscaleDeciderCallable.java
class i have attached the diff file to mail.
Best regards,
Umut
