One of the barriers to entry for trying out TripleO and its derivatives has been the relative difficulty in getting an environment up quickly.

This set of ansible roles is meant to help.

Quickstart's default deployment method uses a physical machine, which is referred to as $VIRTHOST throughout this documentation. On this physical machine Quickstart sets up multiple virtual machines (VMs) and virtual networks using libvirt.

One of the VMs is set up as undercloud, an all-in-one OpenStack cloud used by system administrators to deploy the overcloud, the end-user facing OpenStack installation, usually consisting of multiple VMs.

You will need a $VIRTHOST with at least 16 GB of RAM, preferably 32 GB, and you must be able to ssh to the virthost machine as root without a password from the machine running ansible. Currently the virthost machine must be running a recent Red Hat-based Linux distribution (CentOS 7.x, RHEL 7.x). Other distributions could work but will not be supported with out CI validation.


Running commands as root is not suggested or supported.

The SSH server on your $VIRTHOST must be accessible via public keys for both the root and stack users.

A quick way to test that root to your virthost machine is ready to rock is:

ssh root@$VIRTHOST uname -a

The stack user is not added until the quickstart deploy runs, so this cannot be tested in advance. However, if you lock down on a per-user basis, ensure AllowUsers includes stack.

Timeouts can be an issue if the SSH server is configured to disconnect users after periods of inactivity. This can be addressed for example by:

ClientAliveInterval 120
ClientAliveCountMax 720

The quickstart defaults are meant to "just work", so it is as easy as downloading and running the script.
