Chapter 7. OpenStack playbooks

Figure 7.1. Installation work flow

The main Ansible OpenStack playbook installs OpenStack services and performs the following operations:

• Install common components
• Create a utility container that provides utilities to interact with services in other containers
• Install Identity (keystone)
• Generate service IDs for all services
• Install the Image service (glance)
• Install Orchestration (heat)
• Install Compute (nova)
• Install Networking (neutron)
• Install Block Storage (cinder)
• Install Dashboard (horizon)
• Reconfigure Rsyslog

Running the OpenStack playbook

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

2. Run the OpenStack setup playbook:

   # openstack-ansible setup-openstack.yml
   

   The openstack-common.yml sub-playbook builds all OpenStack services from source and takes up to 30 minutes to complete. As the playbook progresses, the quantity of containers in the polling state approaches zero. If any operations take longer than 30 minutes to complete, the playbook terminates with an error.

   Setting up the compute hosts takes up to another 30 minutes to complete, particularly in environments with many compute hosts. If any operations take longer than 30 minutes to complete, the playbook terminates with an error.

   Confirm satisfactory completion with zero items unreachable or failed:

Utility container

The utility container provides a space where miscellaneous tools and software are installed. Tools and objects are placed in a utility container if they do not require a dedicated container or if it is impractical to create a new container for a single tool or object. Utility containers are also used when tools cannot be installed directly onto a host.

For example, the tempest playbooks are installed on the utility container since tempest testing does not need a container of its own.

Verifying OpenStack operation

Verify basic operation of the OpenStack API and dashboard.

Procedure 8.1. Verifying the API

The utility container provides a CLI environment for additional configuration and testing.

1. Determine the utility container name:

   # lxc-ls | grep utility
   infra1_utility_container-161a4084
   

2. Access the utility container:

   # lxc-attach -n infra1_utility_container-161a4084
   

3. Source the admin tenant credentials:

   # source /root/openrc
   

4. Run an OpenStack command that uses one or more APIs. For example:

   # openstack user list

   +----------------------------------+--------------------+
   

Procedure 8.2. Verifying the dashboard

1. With a web browser, access the dashboard using the external load balancer IP address defined by the external_lb_vip_address option in the /etc/openstack_deploy/openstack_user_config.yml file. The dashboard uses HTTPS on port 443.
2. Authenticate using the username admin and password defined by the keystone_auth_admin_password option in the /etc/openstack_deploy/user_variables.yml file.

Note

Only users with administrator privileges can upload public images using the dashboard or CLI.
