What is the trigger in the UI in order to know when a node from an ami in complete when launched using knife?


#1

Hi,

I am using knife to launch an ami from python. Then I need to execute
a loop the will be checking the UI using PyChef so when the node is
complete…I can do further processing.

So…what is the field that I should be monitoring that 1) if the
field exists and 2) if it does exists goes from one state to another.
i.e. all ready.

Thanks

Why use knife instead of boto and fabric? You could monitor ohai_time in the node attributes, that is just the timestamp of the last chef run, but using boto to do the launch and then watch the instance status and then fabric to check SSH might be easier in the long run.
