Hi Shaheed,
I have found couple of issues in your application definition. You have
given the value "0" to groupMinInstances and groupMaxInstances properties
in all the group references . So No groups being created and execution
stops at that point.
"name":"blade",
"alias":"blade",
"groupMinInstances":0,
"groupMaxInstances":0
Please give a positive numbers to these properties and try again.
And we don't need to specify the application status ("status":"Deployed")
in application definition. It will be set to "Deployed" by auto-scaler once
an application is successfully deployed.
PS - We should modify our addApplication() rest API in a way that the bean
class should not have application status attribute. Otherwise if someone
sets this attribute in application definition, it will cause issues in AS.
Thanks.
