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.
You will need a host machine (referred to as $VIRTHOST) with at least
16G of RAM, preferably 32G, and you must be able to ssh to the
virthost machine as root without a password from the machine running ansible.
Currently the virthost machine must be running a recent Red Hat-based Linux
distribution (CentOS 7, RHEL 7, Fedora 22 - only CentOS 7 is currently tested),
but we hope to add support for non-Red Hat distributions too.
A quick way to test that your virthost machine is ready to rock is:
ssh root@$VIRTHOST uname -a
The defaults are meant to "just work", so it is as easy as downloading
and running the quickstart.sh script.
You can download the quickstart.sh script with wget:
wget 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
Deploy your virtual environment by running:
bash quickstart.sh $VIRTHOST
Where $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, mitaka is used.
bash quickstart.sh -p quickstart-extras.yml -r quickstart-extras-requirements.txt --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.
bash quickstart.sh localhost
Please note the following when using quickstart to deploy tripleo directly on
localhost. 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. An alternative workflow is being
tested and can be found under tripleo-quickstart/ci-scripts/usbkey/.
If you are working on TripleO upstream development, and need to reproduce what runs in tripleo-ci, you will want to use developer mode.
This will fetch the images produced by tripleo-ci instead of the ones produced by RDO. The incantation for a job using the quickstart defaults other than developer mode would be:
bash quickstart.sh \
--release master-tripleo-ci \
$VIRTHOST
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.
