Release notes for the project can be found at: https://docs.openstack.org/releasenotes/tripleo-quickstart/
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
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
deployer ALL=(ALL) NOPASSWD: ALL
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
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
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

Getting the script¶
You can download the
quickstart.sh script with
curl -O https://raw.githubusercontent.com/openstack/tripleo-quickstart/master/quickstart.sh
Alternatively, you can clone this repository and run the script from there.
You need some software available on your local system before you can run
quickstart.sh. You can install the necessary dependencies by running:
bash quickstart.sh --install-deps
Deploying with instructions¶
Deploy your virtual environment by running:
bash quickstart.sh $VIRTHOST
$VIRTHOST is the name of the host on which you want to install your
virtual triple0 environment. The
quickstart.sh script will install this
repository along with ansible in a virtual environment on your Ansible host and
run the quickstart playbook. Note, the quickstart playbook will delete the
stack user on
$VIRTHOST and recreate it.
This script will output instructions at the end to access the deployed
undercloud. If a release name is not given,
queens is used.
Deploying without instructions¶
bash quickstart.sh --tags all $VIRTHOST
You may choose to execute an end to end deployment without displaying the
instructions and scripts provided by default. Using the
--tags all flag
will instruct quickstart to provision the environment and deploy both the
undercloud and overcloud. Additionally a validation test will be executed to
ensure the overcloud is functional.
Deploying on localhost¶
bash quickstart.sh 127.0.0.2
Please note the following when using quickstart to deploy tripleo directly on
localhost. Use the loopback address
127.0.0.2 in lieu of localhost as
localhost is reserved by ansible and will not work correctly. The deployment
should pass, however you may not be able to ssh to the overcloud nodes
while using the default ssh config file. The ssh config file that is generated
by quickstart e.g.
~/.quickstart/ssh.config.ansible will try to proxy
through the localhost to ssh to the localhost and will cause an error
if ssh is not setup to support it.
bash quickstart.sh -X -b $VIRTHOST
Please note that ~/.quickstart folder cannot be reused between deployments. It
has to be removed before executing quickstart.sh again. Using the
the script will remove this directory and create it again.
Note that using
-b flag will also force the creation of the virtualenv
environment and the installation of any requirement.
Enable Developer mode¶
Please refer to the OpenStack Documentation
Feature Configuration and Nodes¶
In previous versions of tripleo-quickstart a config file was used to determine not only the features that would be enabled in tripleo and openstack but also the number of nodes to be used. For instance “config/general_config/ha.yml” would configure pacemaker and ensure three controller nodes were provisioned. This type of configuration is now deprecated but will still work through the Queens release.
The feature and node configuration have been separated into two distinct configuration files to allow users to explicity select the configuration known as “feature sets” and the nodes to be provisioned. The feature set configuration can be found under tripleo-quickstart/config/general_config/ and the node configuration can be found under tripleo-quickstart/config/nodes/
A more in depth description of the feature sets can be found in the documentation under Feature Configuration
A more in depth description of how to configure nodes can be found in the documentation under Node Configuration
Working With Quickstart Extras¶
TripleO Quickstart is more than just a tool for quickly deploying a single machine TripleO instance; it is an easily extensible framework for deploying OpenStack.
For a how-to please see Working With Quickstart Extras
Setting up libvirt guests only¶
At times it is useful to only setup or provision libvirt guests without installing any TripleO code or rpms. The tripleo-quickstart git repository is designed to provision libvirt guest environments. Some may be familiar with an older TripleO tool called instack-virt-setup, these steps would replace that function.
To deploy the undercloud node uninstalled and empty or blank overcloud nodes do the following.:
bash quickstart.sh --tags all --playbook quickstart.yml $VIRTHOST
To only deploy one node, the undercloud node do the following.:
bash quickstart.sh --tags all --playbook quickstart.yml -e overcloud_nodes="" $VIRTHOST
