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.
Quickstart tool runs commands with superuser privileges as installing packages
to the deployer system. The script should be run by a sudo user, e.g.
deployer, which should be added to the sudoers configuration, as shown
below:
deployer ALL=(ALL) NOPASSWD: ALL
Note
Running quickstart.sh 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 quickstart.sh script.
