Resources from heat template
We have setup an instance of ONAP based on "vanilla" Openstack (Ocata). Similarly to Resources and Sizing on Rackspace I would like to have a space for vanilla Openstack installs. The table below is generated by a little script (see attachment) based on the flavors used in our setup and the onap_openstack.yaml file.
| Nr. | VM | FLAVOR | CPU | RAM | DISK |
| 1 | dns | SMALL | 1 | 2 | 20 |
| 2 | aai | XLARGE | 8 | 16 | 160 |
| 3 | mso | LARGE | 4 | 8 | 80 |
| 4 | mrouter | LARGE | 4 | 8 | 80 |
| 5 | robot | SMALL | 1 | 2 | 20 |
| 6 | vid | MEDIUM | 2 | 4 | 40 |
| 7 | sdnc | LARGE | 4 | 8 | 80 |
| 8 | sdc | XLARGE | 8 | 16 | 160 |
| 9 | portal | LARGE | 4 | 8 | 80 |
| 10 | dcae_c | MEDIUM | 2 | 4 | 40 |
| 11 | policy | XLARGE | 8 | 16 | 160 |
| 12 | appc | LARGE | 4 | 8 | 80 |
| total | ..... | 50 | 100 | 1000 |
(n.b.: Need to update #vCPU for dcae still)
Openstack Defaults.
To get the HEAT template to load, we needed to change some defaults in the Openstack install.
I think we increased RAM, Instances, vPCUs to enable the resources needed by the HEAT template

Physical infrastructure
One controller node, two compute nodes (Blades in a pureflex center)
specs: <tbd>
Other observations
A few observations we made during the setup of on vanilla Openstack.
Robot_vm
The demo.sh script fails all tests, with the first being "access". Further investigation unveils that a file contains a parameters pointing to Rackspace.
/opt/eteshare/config/integration_robot_properties.py , at or around line 30 "GLOBAL_OPENSTACK_KEYSTONE_SERVER" to be changed to your keystone server as http://<your keystone server>:5000.
Now the scripts fails at another point, but I'll find out why and will report here.
