How to Manage OpenStack Private Clouds Episode 4 - Building Virtual Networks (Neutron)

OpenStack is an open-source cloud computing platform that enables you to build your very own private cloud that is completely under your control. You can use it to spin up compute instances, set up block and object storage, load balancers, software-defined networking, and more. In this six-part guide, Jay will guide you through the finer points of OpenStack with hands-on examples. In the fourth episode, we'll take a look at networking-related topics within OpenStack.

[@aqeelabbas8264]

so good to see this episode I've been waiting for... thank you so much!

[@jorgevisentini]

Hey man! Great video. Good explanation. Eager to the next video. Thank youu!

[@fedefede843]

It would be nice to see a VPN jump in box setup, to ssh into those internal servers instead using the floating IP.
Great tutorial!

[@davidgreen7392]

Private Cloud? Surely the question should be: "Where is it's storage of my defunct electric personal SUV?"

[@jg1000c]

Helpful, thanks

[@bellangerbenjamin1460]

Is there a specific reason for removing default SSH ingress and adding new SSH_access instead ? Or is it only for the purpose of the tutorial ? Thank you for your answer !

[@RustyNPiece]

Yes, for the purpose of the tutorial. See 8:24

[@jawadnet91]

great content and clear explanation. follows your steps but i am facing issue to access internet from my openstack instances and not able to install anything. my instance is on private network and associated a floating IP to it but unsuccessful. does anyone face this same issue.

[@openmetal_io]

This can be caused by several factors but my guess it's the network or router:
-Network Configuration: Check subnet settings, DHCP configuration, and router settings to ensure proper connectivity.
- Check that your router is connected to the external network with internet access

I am trying to follow along but created Open Stack on a virtual machine; I am not using Open Metal. Is there a tutorial or guide on how to tie my home network (which was not automatically created in open stack) to a private network? I assume my home network is acting like a provider network but I can't find anywhere on how one would create a provider network in Open Stack. TIA.

[@openmetal_io]

Try:
Log into OpenStack controller node
Source OpenStack Credentials
Create Provider network "openstack network create --external --provider-physical-network physnet1 --provider-network-type flat provider-network"

[@act.13.41]

The new intro music is better.

[@alx8439]

I'd say you shoud never make your ssh service public, unless you're using key based authentication.

[@George-664]

I will better learn cloudstack. Openstack is too much complicated.
