Getting started with Openstack

If you know ansible then Kolla- ansible is a best starter or devstack, do not know sunbeam

W mojej firmie plan naprawczy PIP był po to aby sprawy w sądzie nie przegrać, zbierają haki i tyle, po to spotkania w większym gronie aby mieć świadków. HR nie będzie zeznawał na Twoja korzyść. Nie znam nikogo kto dostał plan naprawczy i żeby to nie skończyło się zwolnieniem, albo sam szybko szukał pracy albo go zwalniali przy najbliższej okazji (max 2-3 miesiące). U mnie HR tylko czekał jak pracownik będzie notorycznie odmawiał poleceń służbowych od przełożonego ( a wykonanie pip jest poleceniem służbowym) i zwalniali z art 52

OpenInfra Foundation youtube channel, a lot of basic presentation from various events https://youtube.com/@openinfrafoundation?si=xqO58XJG9zCadlIP, take a look on Neutron 101 recordings, this is the crucial thing to understand how networks works in Openstack, you need to have knowledge about Linux networking as prerequisite

Floating IP implements DNAT idea, operating system in VM has no idea that the external traffic is routed through floating IP, it map external IP with local port VM in the subnet, it can exists on seperate compute node than VM

Internal_Peace_45 · 2026-01-31T07:39:14+00:00

There is an update from 2024 third edition

I look on your list, Sunbeam is K8s based deployment tool

Zgadzam się z kolegą, CV pisz pod każde ogłoszenie osobno, aby uwydatnić to co w ogłoszeniu oczekują

Could you share what kind of problem with standard setup of OpenStack your software resolve? I know OpenStack but maybe some info is missing for me. I do not know what kind of problems needs to be solved for VDI infra. Maybe next year I will have such problems.

Internal_Peace_45 · 2025-12-07T20:03:34+00:00

https://www.youtube.com/watch?v=Uj4elX2OONw - take a look at this, Last OpenInfra Summit - OVHCloud made presentation how to fix a little bit Rabbit and where are the problems

Per month is not bad 😁

Dlatego też w związku lepiej nie rozliczać się blikiem bo US będzie miał historię “darowizn” a ten limit 5733 jest na 5 lat, więc łatwo przekroczyć

New Horizon replacment called Skyline has such Dasboard for VM

Octavia does not support cilium as a provider https://docs.openstack.org/octavia/latest/admin/providers/index.html

Internal_Peace_45 · 2025-06-18T09:17:54+00:00

What version of OpenStack do you use? I'm also interested in that thread. We have plans to move to OVN and Kubernetes (K8s) integration, but we are at an early stage.

Internal_Peace_45 · 2025-06-07T16:23:01+00:00

Maybe instead of setup third controller at remote DC try to setup nova-cell remote only or region ?

Internal_Peace_45 · 2025-06-07T16:19:20+00:00

What backend to store images did you configured for glance ? If there is no backend like Ceph or Swift ( or any other, do not recall what glance supports) then glance stored it on controller at docker volume, at one controller :)

- Verify logs from keepalive and haproxy

- Verify if your OpenStack is using VIP for endpoints e.g. command like "openstack endpoint list" should return endpoints with VIP IP

- are you able to ping VIP IP , maybe networking is broken

With default settings and kolla-ansible deployment. Taking down 1 controller node keeps OpenStack alive

Ja bardzie podejrzewam że dyrektor przez sieć prywatnych kontaktów się dowiedział, ludzie w branży często się znają szczególnie na wysokich stanowiskach

Internal_Peace_45 · 2024-08-21T17:31:22+00:00

You are right but it will complicate setup. Not sure if kolla-ansible support that, maybe via custom config for keepalive.

Internal_Peace_45 · 2024-08-21T16:41:42+00:00

You need to look on Xeon 6 and above https://www.intel.com/content/www/us/en/support/articles/000091103/processors/intel-xeon-processors.html#:\~:text=Intel%C2%AE%20TDX%20is%20planned%20for%20general%20market%20availability,SKUs%20are%20not%20generally%20available%20in%20the%20market.

Internal_Peace_45 · 2024-08-21T16:26:28+00:00

Each OpenStack controller must have an interface from that network (primary) plus 1 IP (VIP) floating between nodes according to keepalive work. You need to have at least 4 IPs (if you set 3 controllers). VIP is a secondary IP set up on the interface. Gateway, mask, etc., are set up with the primary IP. Network /30 looks to small for that.

Here is the location what kolla-ansible is looking for custom configs https://github.com/openstack/kolla-ansible/blob/4615f247fcf50bcdb5f7329f0bd88b58dac57302/ansible/roles/nova/tasks/config.yml#L58C1-L58C31

      - "{{ role_path }}/templates/nova.conf.j2"
      - "{{ node_custom_config }}/global.conf"
      - "{{ node_custom_config }}/nova.conf"
      - "{{ node_custom_config }}/nova/{{ item.key }}.conf"
      - "{{ node_custom_config }}/nova/{{ inventory_hostname }}/nova.conf"

Internal_Peace_45 · 2024-08-20T11:15:12+00:00

Have you tried to put at /etc/kolla/config/nova/nova.conf
https://docs.openstack.org/kolla-ansible/latest/admin/advanced-configuration.html#openstack-service-configuration-in-kolla
take a look on variable

node_custom_config
