Deploying Openstack

With RHEL OSP 7 and Director

Pablo Sanchez Red Hat OpenStack SpecialistAmsterdam OpenStack Meetup, 2/12/2015

About me

Openstack Technical Specialist @ Red HatWorking with Openstack since Folsom ReleaseWorked before for Rackspace in the public cloud Ops team@openpabz

Agenda

● What is RHEL OSP-Director

● How we deploy Openstack using it in RH

● Demo

RHEL OSP DirectorRed Hat's new installation, configuration, and monitoring toolset for RHEL

OSP deploymentsHas mechanisms of the following

1. Installing the Installer 2. Identification of the target hosts - the one's we're installing onto3. Content management for the software to be deployed4. Defining the topology and configuration of the deployment5. Bare metal provisioning via automated hardware control6. Software rollout and configuration management7. Making modifications to an already director-deployed environment

RHEL OSP Director

Uses Openstack Upstream components TripleOIronicHeat +Puppet

Community Version RDO Manager

6

7

1. One or more Management Nodes “Undercloud”

8

2. Operator Dashboard & CLI interfaces to configure the infrastructure

9

3. Optional introspection & benchmarking of hardware.

Hardware Discovery

10

4. Operator defines the OpenStack control services.

11

5. Operator defines the OpenStack resource nodes.

12

6. Control service and Resource nodes get provisioned.“Overcloud”

(Heat -> Nova -> Ironic -> Hardware)

OSP Director in a nutshell

Undercloud Installation

Set up the Undercloud hostname

Undercloud node needs to have a fqdn matching and entry in /etc/hosts :

Install the Undercloud package

Configure the Undercloud

Install the Undercloud

Undercloud Video

Overcloud Installation

Download the Overcloud Images

Define the Nodes as Ironic hosts

Import the Nodes into Ironic

Discover the HW of the Nodes

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

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

Get the Heat templates

$ cp -rf /usr/share/openstack-tripleo-heat-templates ~/templates/

Plan your network

Adapt templates to the env

Write your controller’s NIC configuration Heat templates

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

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
