Chapter 5. Foundation playbooks

Figure 5.1. Installation work flow

The main Ansible foundation playbook prepares the target hosts for infrastructure and OpenStack services and performs the following operations:

• Perform deployment host initial setup
• Build containers on target hosts
• Restart containers on target hosts
• Install common components into containers on target hosts

Running the foundation playbook

Before continuing, the configuration files may be validated using the guidance in "Checking the integrity of your configuration files".

1. Change to the /opt/openstack-ansible/playbooks directory.

2. Run the host setup playbook, which runs a series of sub-playbooks:

   # openstack-ansible setup-hosts.yml

   Confirm satisfactory completion with zero items unreachable or failed:

   PLAY RECAP ********************************************************************
   ...
   deployment_host                :  ok=18   changed=11   unreachable=0    failed=0

3. If using HAProxy:

   Note

   If you plan to run haproxy on multiple hosts, you'll need keepalived to make haproxy highly-available. The keepalived role should have been downloaded during the bootstrap-ansible stage. If not, you should rerun the following command before running the haproxy playbook:

   # pushd /opt/openstack-ansible; scripts/bootstrap-ansible.sh; popd

   or

   # ansible-galaxy install -r ../ansible-role-requirements.yml

Run the playbook to deploy haproxy:

# openstack-ansible haproxy-install.yml
