Re: Openshift Origin V3 installation on Openstack.


I tried to connect dots and if I understand correctly I'll need to provision few VMs on OpenStack which will become Master and Nodes. Then, follow the Host Preparation steps on those VMs and rest will be taken care by ansible as Master and Nodes will be mentioned in the ansible hosts file.

Is this correct?

Now, if this is correct I have doubts about the variables to set for ansible. I'll appreciate if someone can guide.
The OpenStack is installed locally in lab environment and is not publicly accessible. Also, DNS request to public DNS are blocked from the lab.

I know I am asking to much but the guide assumes prior knowledge of lot of things but I do not have any experience on such things.

Thanks & Regards,

Hi Alberto,

Thanks for clarification. Yes, I'll do the ansible installation.

I still have few doubts in the Host Preparation section of the https://docs.openshift.org/latest/install_config/install/prerequisites.html.

By host I understand the Compute Nodes of openstack. So, the first mentions to manage packages as yum install wget git net-tools bind-utils iptables-services bridge-utils bash-completion  but as mentioned earlier I have Ubuntu setup. Do I need to find equivalent apt packages?

Second step is to clone ansible, I suppose that is not on host but on the machine from which I'll do the installation.

Third step is to do Docker installation on host. This is fine. I can install this on Compute Nodes.

Thanks & Regards,

Yes, in this case it doesn't matter.

Do you mean the advanced installation using ansible playbooks?

In that case it can be executed from any computer able to establish a ssh passwordless connection to the OpenShift master and nodes, tipically an external computer. I don't think it would be a good idea to use the OpenStack controller for that.
