Slides from Ramon Acedo, Red Hat from the London Openstack Meetup, Noovember 18th, 2015. RHEL OSP 7, TripleO and director

1. OpenStack Lab
With RHEL OSP 7, TripleO and director
Ramon Acedo
Red Hat OpenStack Specialist
London OpenStack Meet-up, November 2015

2. Goals
Experiment with RHEL OSP director in your own laptop
Understand how TripleO is used to install OpenStack
Prepare real environments

3. Tools
Laptop with 16 GB of RAM and fast HDD
If Mac OSX, VMware Fusion Professional
If Linux, VMware Workstation or Libvirt+KVM

5. Create the VMs in your laptop

6. Undercloud VM networks

7. Set up the Undercloud network

8. Set up the Undercloud hostname

9. Install the Undercloud package

10. Configure the Undercloud

11. Install the Undercloud

12. Ironic fake_pxe driver

13. Download the Overcloud Images

14. Define the VMs as Ironic hosts

15. Import the VMs into Ironic

16. Discover the HW of the VMs

17. 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

18. 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

19. Get the Heat templates

20. Plan your network

21. Write your network environment Heat
template

22. Plan your controller’s NIC configuration

23. Write your controller’s NIC configuration
Heat templates

24. Do the same with your compute node

25. Let’s enable swap, create the main template
New template in:
/home/stack/templates/firstboot/firstboot.yaml

26. Let’s enable swap, create the script
And the userdata.yaml called from the template:

27. Summary before deploying

28. 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
