This document summarizes a presentation about deploying OpenStack with Red Hat Enterprise Linux OpenStack Platform (RHEL OSP) 7 and Director. It discusses: 1. What RHEL OSP Director is and how it is used to install, configure, and monitor RHEL OSP deployments through mechanisms like installing the installer, identifying target hosts, managing content, defining topology, and provisioning hardware. 2. How RHEL OSP Director uses upstream OpenStack components like TripleO, Ironic, and Heat along with Puppet to deploy the undercloud management nodes and overcloud workload nodes. 3. The steps to deploy the undercloud and overcloud through the director including configuring the undercloud, discovering

3. Agenda
● What is RHEL OSP-Director
● How we deploy Openstack using it in RH
● Demo

4. RHEL OSP Director
Red Hat's new installation, configuration, and monitoring toolset for RHEL
OSP deployments
Has mechanisms of the following
1. Installing the Installer
2. Identification of the target hosts - the one's we're installing onto
3. Content management for the software to be deployed
4. Defining the topology and configuration of the deployment
5. Bare metal provisioning via automated hardware control
6. Software rollout and configuration management
7. Making modifications to an already director-deployed environment

20. OSP Director in a nutshell

22. Undercloud Installation

23. Set up the Undercloud hostname
Undercloud node needs to have a fqdn matching and entry in /etc/hosts :

24. Install the Undercloud package

25. Configure the Undercloud

26. Install the Undercloud

27. Undercloud Video

28. Overcloud Installation

29. Download the Overcloud Images

30. Define the Nodes as Ironic hosts

31. Import the Nodes into Ironic

32. Discover the HW of the Nodes

33. Add nodes to roles and create their flavors
$ ironic node-update $node_id add properties/capabilities='profile:compute,boot_option:local'
$ ironic node-update $node_id add properties/capabilities='profile:control,boot_option:local'
$ openstack flavor create --id auto --ram 3000 --disk 17 --vcpus 2 --swap 2000 compute
$ openstack flavor create --id auto --ram 3000 --disk 19 --vcpus 2 --swap 1500 control
$ openstack flavor create --id auto --ram 3000 --disk 19 --vcpus 2 baremetal

34. Associate flavors to roles
$ openstack flavor set --property "cpu_arch"="x86_64" --property
"capabilities:boot_option"="local" --property "capabilities:profile"="control" control
$ openstack flavor set --property "cpu_arch"="x86_64" --property
"capabilities:boot_option"="local" --property "capabilities:profile"="compute" compute

35. Get the Heat templates
$ cp -rf /usr/share/openstack-tripleo-heat-templates ~/templates/

36. Plan your network
Network Subnet VLAN
Provisioning 172.16.0.0/24 Native
Internal API 172.17.1.0/24 101
Tenant 172.17.2.0/24 201
Storage 172.17.3.0/24 301
Storage Management 172.17.4.0/25 401
External 192.168.122.0/24 Native

37. Adapt templates to the env

38. Write your controller’s NIC configuration
Heat templates

39. Summary before deploying
What we need
● Undercloud configured and ready
● Nodes discovered and available in Ironic
● Flavors created and nodes matched
● Images downloaded (or created)
● Heat Templates adapted for our environment

40. Let’s deploy the Overcloud
openstack overcloud deploy --templates ~/templates/
--ntp-server 192.168.122.1
--control-flavor control --compute-flavor compute --ceph-storage-flavor ceph
--control-scale 3 --compute-scale 2 --ceph-storage-scale 3
--neutron-tunnel-types vxlan --neutron-network-type vxlan
-e ~/templates/environments/storage-environment.yaml
-e ~/templates/environment.yaml
