Hi everyone,

I'm a newbie of using Kolla-ansible to deploy OpenStack.
Everything works well. But I have few questions about Kolla since I was using Fuel as deploy tool before.
The questions may silly, but I really want to know since I didn't found much informations to solve my questions..

About offline deployment:

I already known that we need have OS local repository (CentOS or Ubuntu), docker local package repository, and local docker registry.
But one thing I'm not sure that it will use pip to install python packages or not. Because I found it will also install pip into target node during bootstrap-servers.
If so, which python package should I prepare for?

If you are using bootstrap-servers, you will need the pip and docker Python packages available for installation.

Are you building your own images? If so you will probably find it easier to use binary images than source since these use OS distro packages.

About operation:

1. Is it possible to operate a single service to whole OpenStack nodes? Like using crm to check status about MySQL or RabbitMQ services on all control nodes.

We don't have a simple way to manage the whole cluster of services from one place. You can use the docker CLI, perhaps configured for TCP transport if you want remote control, or just via SSH if you don't want to expose it to the network.

2. How can I maintenance the Ceph OSD if OSD down caused by disk issue?
I know how to rebuild OSD by Ceph commands but I'm not sure how to do if ceph-osd running in container.

I don't tend to use Ceph in kolla, so I can't really answer this one. I couldn't see anything about this in the docs.

Many thanks,
Eddie.
