OpenStack Lab

With RHEL OSP 7, TripleO and director

Ramon AcedoRed Hat OpenStack SpecialistLondon OpenStack Meet-up, November 2015

Goals

Experiment with RHEL OSP director in your own laptop

Understand how TripleO is used to install OpenStack

Prepare real environments

Tools

Laptop with 16 GB of RAM and fast HDD

If Mac OSX, VMware Fusion Professional

If Linux, VMware Workstation or Libvirt+KVM

Create the VMs in your laptop

Undercloud VM networks

Set up the Undercloud network

Set up the Undercloud hostname

Install the Undercloud package

Configure the Undercloud

Install the Undercloud

Ironic fake_pxe driver

Download the Overcloud Images

Define the VMs as Ironic hosts

Import the VMs into Ironic

Discover the HW of the VMs

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

Plan your network

Write your network environment Heat template

Plan your controller’s NIC configuration

Write your controller’s NIC configuration Heat templates

Do the same with your compute node

Let’s enable swap, create the main template

New template in:

/home/stack/templates/firstboot/firstboot.yaml

Let’s enable swap, create the scriptAnd the userdata.yaml called from the template:

Summary before deploying

Let’s deploy the Overcloud

$ openstack overcloud deploy \--templates templates/openstack-tripleo-heat-templates/ \-e templates/openstack-tripleo-heat-templates/environments/network-isolation.yaml \-e templates/network-environment.yaml \-e templates/firstboot/firstboot.yaml \--control-flavor control \--compute-flavor compute \--neutron-tunnel-types vxlan --neutron-network-type vxlan \--ntp-server clock.redhat.com
