Can't successfully destroy provisioned VM based on contrainfra/linchpin

[Dannyb48]

From what I can gather, the RunDB that Linchpin uses to store the resource state info was empty for that target:

TASK [openstack : Get topology output data from RunDB] *************************
ok: [localhost] => {"changed": false, "output": "[]"}

Not sure if that is left over from the prior failed deletion attempt.

Can you try reproduce this again now that you upgraded the contra container to linchpin 2.0.2?

• provsion your VM
• destroy your VM

* provsion your VM

* destroy your VM

As you seen, I have done this, please see previous comments, please let me know if you need extra information.

BTW, I had ever removed manually several provisioned VM instances from Openstack webUI, I guess it may be reason, it will be better if there is a command like linchpin list --provisioned/fresh to get latest provisioned VM instances information.

I reproduced it in a non-container environment.

    "ansible_facts": {
        "topo_output_json": []
    }, 
    "changed": false
}

    "msg": "The task includes an option with an undefined variable.

}

Without provisioning anything I just ran:

linchpin --no-monitor -vvvv destroy

``

As I suspect nothing is there in the database related to that target for it retrieve hence it fails.

It's a valid feature suggestion linchpin list --provisioned/fresh but unfortunately Linchpin is in maintenance mode right now. So we are only really providing support and fixes to already existing functionality.

@chuanchang Any chance we can close this out?
