Network "net_mgmt" in manual Tacker installation

[Roger Luethi]

The sample sample-vnfd.yaml on that page uses a network_name "net_mgmt". The name is used by devstack, but these are the instructions for a manual installation which follows (according to the previous page of the instructions) the OpenStack install-guide. The correct network name is therefore not net_mgmt. Presumably, the best choice is "selfservice".

cannot quite understand.

[Roger Luethi (rl-o)]

Sorry, I will try to be more precise.

The getting_started.html page linked in the bug report above contains a sample-vnfd.yaml file. In that file, one line reads: "network_name: net_mgmt".

"net_mgmt" is the name of a network which has to exist already (it is not created in the Tacker installation instructions). The network is a prerequisite.

A network with the name, "net_mgmt" is created by devstack. However, the manual installation instructions for Tacker do not use devstack. If you go one step back to https://docs.openstack.org/tacker/latest/install/manual_installation.html, you will see that it links to the OpenStack documentation site which hosts the OpenStack install-guide (https://docs.openstack.org/ocata/install-guide-ubuntu/). Users who follow that install-guide will _not_ have a network called "net_mgmt". Therefore, the sample sample-vnfd.yaml will not work.

Of the networks that do exist in such a non-devstack, install-guide cluster, the most suitable replacement for "net_mgmt" is probably a network named "selfservice".

Does that make more sense?

I am currently building a Tacker installer for the OpenStack training-labs which is a fully automated installer for OpenStack. It follows the install-guide and the manual installation instructions for Tacker. That is why I am hitting this problem (and some others I reported).
