Adventures of a Small Time OpenStack Sysadmin Chapter 016 - OpenStack Horizon UI

Adventures of a Small Time OpenStack Sysadmin relate the experience of converting a small VMware cluster into two small OpenStack clusters, and the adventures and friends I made along the way.

Adventures of a Small Time OpenStack Sysadmin Chapter 016 - OpenStack Horizon UI

Horizon is a pretty easy install.  Note that the docs on page:

https://docs.openstack.org/horizon/yoga/install/install-ubuntu.html

Refer to OPENSTACK_KEYSTONE_URL on port 80, and if you've been following along in the instructions, you set it up on port 5000, and there is a note in the docs on that topic.

I note that Kolla-Ansible also installs Keystone on port 5000.  So its just kind of odd to see a suggestion of running Keystone on port 80, I have not seen that anywhere else.

On identical hardware, Kolla-Ansible's Horizon is vastly faster.  I suspect something to do with different WSGI configurations.

You will need the "Horizon Plugin Registry" later on when installing add-on services.

When I first set up Horizon and Keystone I placed pretty much the entire LAN into one project, which is slow to use and slow to page thru multiple screens in Horizon.  My solution for Plan 2.0 of breaking everything into smaller projects makes Horizon much more usable.  My architecture advice would be if you find yourself with multiple pages of Anything in Horizon, you probably need to break your projects down into smaller components, for ease of use reasons if nothing else.

Stay tuned for the next chapter!
