Hello Nik, Ahamad,
I've asked on the list what API implementation to use [1] . From my
experience, when working with API's you end up writing a client. So if
one is already provided I choose to use that. It tends to be tested
and makes development easy and the code maintainable. Nobody wants
code that's hard to maintain. I could add a few more arguments but
it's not the point.
I guess my point of asking is you really don't need an API client to
talk to the CS API, it is drop dead simple.
Regarding the expunge time, I've tested with a cloud that kept
machines in 'Destroyed' state for as long as 20 minutes or more. I
never stayed so long as to see how long, but the idea is that I can't
clean up networks and maybe other stuff in that time. This is not
something that you would like when you wish to automate stuff around
CloudStack. You NEED to be able clean on demand.
Have you found the TWO parameters that affect expunge time? they are
1800 secs by default: expunge.delay and expunge.interval. Also,
expunge.workers is how many expunge threads to run at a time. If you set
both of those to 10 and have sufficient expunge workers, the vms will be
expunged.
Unfortunately, you may need to adopt Cloudstack's "lazy" way of cleaning
up, which is to create a scheduled task that goes through and cleans up
every hour or so. The lack of VMs in an account is not a reason to
delete the network, unless you are also trying to delete the account
along with it.
Ahamad: I'm using [2] fot documentation. I have tests that create and
delete[3] networks and work fine [4]. The network does not get deleted
when there are VM's associated with it. The delete network operation
fails, the VM's can be destroyed, or expunging, it doesn't matter.
