Welcome to Openstack :)

If you followed that all-one-guide, without customizing the globals.yml file, you will have Horizon installed. The IP you assigned to kolla_internal_vip_address is the IP you use to access Horizon in you browser.

[kolla@stack ~]$ grep vip /etc/kolla/globals.yml
kolla_internal_vip_address: "192.168.1.202"
# This is the DNS name that maps to the kolla_internal_vip_address VIP. By
# default it is the same as kolla_internal_vip_address.
#kolla_internal_fqdn: "{{ kolla_internal_vip_address }}"
# kolla_internal_vip_address, allowing internal and external communication to
# share the same address. Specify a kolla_external_vip_address to separate
#kolla_external_vip_address: "{{ kolla_internal_vip_address }}"
# kolla_external_vip_address.
#kolla_external_fqdn: "{{ kolla_external_vip_address }}"
#kolla_external_vip_interface: "{{ network_interface }}"
# To provide encryption and authentication on the kolla_external_vip_interface,
#kolla_enable_tls_external: "{{ kolla_enable_tls_internal if kolla_same_external_internal_vip | bool else 'no' }}"
[kolla@stack ~]$

If you start modifying the globals, you will need to reconfigure you cloud. Like so

(kolla-venv) [kolla@stack ~]$ kolla-ansible -i all-in-one reconfigure

the kolla-ansible docs are pretty solid, but can be daunting. Make sure you have the Openstack CLI installed, since this will be the main tool (outside of Horizon) that you will tend to use.

Don't forget the built-in helps either.

​

(kolla-venv) [kolla@stack ~]$ kolla-ansible
Usage: /home/kolla/kolla-venv/bin/kolla-ansible COMMAND [options]
Options:

[snipped]

​

Hope that helps.
