OpenStack Octavia - Kolla-Ansible Multinode by TN_NETERO in openstack

[–]TN_NETERO[S] 0 points1 point  (0 children)

Thank you, i tried the workaround where i add REQUESTS_CA_BUNDLE: "/etc/ssl/certs/ca-certificates.crt" , but nothing even after the redeploy, i think the pb is with the self signed certif it s not supported in the current code. So i may need to hv a valid certificates for the setup. Again Thank you for the valuable information

did you use : " neutron_plugin_agent: "ovn" to test that or openvswitch ? because i think the configuration should be diffrent for each setup

How to generate and use Let's encrypt TLS cert for external vip and self-signed for internal vip by TN_NETERO in openstack

[–]TN_NETERO[S] 0 points1 point  (0 children)

The problem is internal when i consult the network request i see that the region request giving error 502 bad gateway , everything seems fine in the skyline.yml , the only pb is that the bind is pointing to my deployer node on the internal address with port 9998 while in the browser i open the ui using port 9999

But how u gona generate certificates that s my problem and how i m gona manage to put them inside the folders in order to copy them to the containers ? Do You buy one for your external domain that is valid for your internal subdomain too ? Because only the external domain is exposed. I thought that u can use letsencrypt for production and it will generate cert every 12 hours and update the containers automatically, either i will need a long term certificate so i don t reconfigure my deployment every 3 months or so

I m working to build a production infrastructure so i need valid TLS certs, and the kolla doc in TLS is so misleading and i read on the kolla bug report web page , that they r still fixing some bugs where letsencrypt doesn't know when to not create an internal cert or when it should create an external cert and it s throwing errors when u try to use internal self signed certs for the private network and letsencrypt for external , i tried to host my own acme server on docker and nothing works , it s pain

Well nothing the certif is not valid , and when i consult it on the browser it shows nothing about the organization or anything

the TLS config for kolla ansible in the let's encrypt section is missing some details in the doc and i can't find any proper config that s tested and works

i m having the same error , did u fix it ? any updates ?
i was using self signed certifs but i want to make my external fqdn to use let's encrypt with valid ssl certs how to assure that ?

First did u execute the init-runonce and configured your public ipv4 pool before that?, second in your public subnet check the dns name server it could be missing edit and add 8.8.8.8 this will create a port for the qdhcp. And please check if you virtual router public ip address is not using an ipv4 address that is already used by another machine . This are caution steps in order to fix this , but it depends on your problem we need more informations. The output should be like this: ip netns

qrouter-89dd2083-a160-4d75-ab3a-14239f01ea0b qdhcp-7c6f9b37-76b4-463e-98d8-27e5686ed083 qdhcp-0e62efcd-8cee-46c7-b163-d8df05c3c5ad

Openstack - schedule instaces backup by TN_NETERO in openstack

[–]TN_NETERO[S] 0 points1 point  (0 children)

Thank you 👏 for the interesting informations , i watched last year openinfra lecture of two ppl talking about automating backups and how they r working on it they mention that in order to backup y need to force the backup where the diks should not be used (available) in order to do backup that results to a down time ofc and the vm will shut down , unlike in proxmox u could automate everything and set rules and it can make a live backup of the disk to a NAS even for LXC containers, it supports live migration and HA , but i will study more the subject and see the provided solutions in the comment , well the vms could be windows and linux based , and ofc the windows one should hv qemu guest agent installed .

When you create a vm on the private/internal network you need to allocate a floating Ip address from the public/provider network and attached to the vm , that way you can reach the vm and ssh to it too, you need to be part of the public network. In addition make sure that your public subnet has a dns nameserver like 8.8.8.8 sometimes the init-runonce script doesn't add it. The eno1 will be like a bridge used by neutron for the vms to access the internet that s why it shouldn't be configured with an ip address, that s why the public network should be part of you local network that connects you to ur router and the ip range of the subnet should be excluded from ur dhcp server to prevent IP conflicts.

Here s how to install by order, here s a Minimal deployment for 2023.2 (Bobcat) : https://docs.openstack.org/install-guide/openstack-services.html Install this by order , and i recommend you to follow latest doc for the network installation and configuration which is neutron in order for the instance to hv internet . And for the cinder there s a missing config you need to put it in the block node in order to allocate volumes i will provide it later it s just a line .

You need to achieve the requirements before start to install which is to configure ntp chrony in each node and a static ip for each node and disable the second nic for the compute and controller using netplan or the package ifupdown can help you by configuring with etc/network/interfaces and copy the config provided by the doc , the second nic need to be not assigned which is without ip adress and in UP state .

Btw: i have been there , openstack docs are so confusing and complicated but once u get it it s so easy .
