Open Stack

Openstack-ansible supports a containerless installation. We test this in 
CI equivalently to the LXC containers deployment - note that these are 
machine containers - analogous to VMs, and not docker type containers.

I would personally choose Ubuntu 20.04 as the OS - mostly due to the 
limited lifetime of python 3.6 which you might find elsewhere, plus the 
availability of a full set of upstream ceph packages which may be harder 
to find for some other distros.

OSA has managed to provide long and heavily overlapping lifecycles for 
Ubuntu based deployments, see 
https://docs.openstack.org/openstack-ansible/latest/en_GB/admin/upgrades/compatibility-matrix.html. 
This is something you should consider when planning how you are going to 
manage and upgrade your deployment. The more overlap you have the more 
freedom you have to work around external factors such as your preferred 
ceph versions.

The tools mentioned in this thread are not really "shrink-wrap" 
installers for OpenStack, only you can architect your deployment to meet 
your particular requirements for hardware, HA, storage and networking 
setup. This architecture has to align with what is possible with the 
deployment tools, and OpenStack in general. Check if the various tools 
provide a reference architecture you can start from.

Take a look at the available documentation, and join the relevant IRC 
channels. Operators using OSA who join #openstack-ansible and be an 
active part of the community are the ones who gain the most value.

Just my opinion - others may vary :)

>  From my understanding, Openstack ansible can be deployed without use of linux containers at all. Did someone try this approach? Is it scalable and stable? The problem is we might have restrictions on using containers at our organisation. So, a container-less solution for deploying and operating Openstack would be very helpful for us.
