From 55cbc98cfe62c5aaf0384bc7ee61b82c29805c1d Mon Sep 17 00:00:00 2001 From: tierno Date: Tue, 6 Oct 2020 08:28:00 +0000 Subject: [PATCH] fix 1238: Provide known ip-address, mac-address at created vnf vnf is created at database. Instantiation parameters of ip-address, mac-adddress are populated to the vnf, so that it is available for jinja2 cloud-init parsing at LCM Change-Id: Ida091f713219f702b753a044683d9474a2670cc1 Signed-off-by: tierno --- osm_nbi/base_topic.py | 20 +++++++++++ osm_nbi/instance_topics.py | 68 ++++++++++++++++++++++++++++++++++---- 2 files changed, 81 insertions(+), 7 deletions(-) diff --git a/osm_nbi/base_topic.py b/osm_nbi/base_topic.py index 5492a8f..9572409 100644 --- a/osm_nbi/base_topic.py +++ b/osm_nbi/base_topic.py @@ -65,6 +65,26 @@ def versiontuple(v): return tuple(filled) +def increment_ip_mac(ip_mac, vm_index=1): + if not isinstance(ip_mac, str): + return ip_mac + try: + # try with ipv4 look for last dot + i = ip_mac.rfind(".") + if i > 0: + i += 1 + return "{}{}".format(ip_mac[:i], int(ip_mac[i:]) + vm_index) + # try with ipv6 or mac look for last colon.
