automated configuration of an OpenStack instance for ONAP
Initial code (based on OpenStack SDK Python client) for configuring an OpenStack instance (e.g. installed by Fuel/MCP) and prepare it for ONAP (especially, to host VM-based VNFs). Currently works: creation of networks, routers, router interfaces, security groups (accessing VMs also works with compute proxy, but is not used for this program). Current issues: identity proxy (so can't create projects and users), adding gateway to router, deletions This script could be launched automatically right after installing OpenStack, and before installing ONAP (so as to grab OpenStack info to be fed into ONAP configuration files). Also, VNF YAML/ENV files can be populated once the OpenStack instance is ready for ONAP. Note: plenty of test and debug lines, which would be removed. This changeset is just to capture a snapshot of this effort in the Auto repository, and to enable reviews and feedback.

+######################################################################
+# This script configures an OpenStack instance (e.g. from an OPNFV installer like FUEL/MCP) to make it
+# ready to interface with an ONAP instance, for example to host VM-based VNFs deployed by ONAP.
+# After running this script, the created OpenStack object names/IDs can be used for example to populate
+# YAML&ENV files used by ONAP (installation of ONAP itself, VNF descriptor files, etc.).
+
+
+######################################################################
+# Overview of the steps:
+#
+# 1) create an ONAP project/tenant (a tenant is a project; project is a more generic term than tenant)
+# (optional, probably not needed: create a new group, which can be associated to a project, and contains users)
+# 2) create an ONAP user within the ONAP project, so as not to use the "admin" user for ONAP
+# (associate user to group if applicable; credentials: name/pwd or name/APIkey, or token)
+# 3) create an ONAP security group, to allow ICMP traffic (for pings) and TCP port 22 (for SSH), rather than changing default security group(s)
+# (optional, probably not needed: create new region)
+# 4a) create a public network for ONAP VNFs, with ports, subnet, and CIDR block
+# (or maybe not necessary? floating_net serves as public/external network and provides pool of floating IP@)
+# 4b) create an OAM network for ONAP VNFs, with ports, subnet, and CIDR block
+# (ONAP VNFs will be deployed in this OMA/private network, which will be connected by router to an external network)
+# 5) create an OpenStack router, with an interface to the OAM/private network (and one to the public network?)
+# and a reference to an external network (gateway)
+# 6) create VM flavors as needed: m1.medium, etc.
+# 7) download images, as needed for ONAP-deployed VNFs: e.g. Ubuntu 14.04, 16.04, ...
+
+
+######################################################################
+# Assumptions:
+# - python3 is installed
+# - OpenStack SDK is installed for python3
+# - there is a clouds.yaml file (describing the OpenStack instance, especially the Auth URL and admin credentials)
+# - the script connects to OpenStack as a user with admin rights
+
+# typical commands to install OpenStack SDK Python client:
+# apt install python3-pip
+# pip3 install --upgrade pip
+# pip3 list
+# pip3 install openstacksdk
+# pip3 install --upgrade openstacksdk
+# pip3 show openstacksdk
+# pip3 check
