This chapter describes how to install SUSE CaaS Platform Heat template on HPE Helion OpenStack.
Download the latest SUSE CaaS Platform for OpenStack image (for example,
SUSE-CaaS-Platform-3.0-OpenStack-Cloud.x86_64-1.0.0-GM.qcow2
)
from https://download.suse.com.
Upload the image to Glance:
openstack image create --public --disk-format qcow2 --container-format \ bare --file SUSE-CaaS-Platform-3.0-OpenStack-Cloud.x86_64-1.0.0-GM.qcow2 \ CaaSP-3
Install the caasp-openstack-heat-templates package on a machine with HPE Helion OpenStack repositories:
zypper in caasp-openstack-heat-templates
The installed templates are located in
/usr/share/caasp-openstack-heat-templates
.
Alternatively, you can get official Heat templates by cloning the appropriate Git repository:
git clone https://github.com/SUSE/caasp-openstack-heat-templates
In Horizon, go to
› › .
Select caasp-stack.yaml
file.
In the
dialog, provide the required information (stack name, password, flavor size, external network of your environment, etc.).Click OpenStack environment. The stack creates one Admin Node, one Master Node, and server worker nodes as specified.
to launch the stack. This creates all required resources for running SUSE CaaS Platform in an
Specify the appropriate flavor and network settings in the
caasp-environment.yaml
file.
Create a stack in Heat by passing the template, environment file, and parameters:
openstack stack create -t caasp-stack.yaml -e caasp-environment.yaml \ --parameter image=CaaSP-3 caasp-stack
After the stack has been created, the Velum SUSE CaaS Platform dashboard runs on the Admin Node. You can access it using the Admin Node's floating IP address.
Create an account and follow the steps in the Velum SUSE CaaS Platform dashboard to complete the SUSE CaaS Platform installation.
When you have successfully accessed the admin node web interface via the floating IP, follow the instructions at https://documentation.suse.com/suse-caasp/3/single-html/caasp-deployment/ to continue the setup of SUSE CaaS Platform.
A Heat stack with load balancing and multiple master nodes can only be created from the command line, because Horizon does not have support for nested Heat templates.
Install the caasp-openstack-heat-templates package on a machine with HPE Helion OpenStack repositories:
zypper in caasp-openstack-heat-templates
The installed templates are located in
/usr/share/caasp-openstack-heat-templates
.
A working load balancer is needed in your SUSE OpenStack Cloud deployment. HPE Helion OpenStack uses HAProxy.
Verify that load balancing with HAProxy is working correctly
in your OpenStack installation by creating a load balancer manually and
checking that the provisioning_status
changes to
Active
.
ardana >
openstack loadbalancer show
<LOAD_BALANCER_ID>
HAProxy is the default load balancer provider in HPE Helion OpenStack.
The steps below can be used to set up a network, subnet, router, security
and IPs for a test lb_net1
network with
lb_subnet1
subnet.
ardana >
openstack network create lb_net1ardana >
openstack subnet create --name lb_subnet1 lb_net1 \ --subnet-range 172.29.0.0/24 --gateway 172.29.0.2ardana >
openstack router create lb_router1ardana >
openstack router add subnet lb_router1 lb_subnet1ardana >
openstack router set lb_router1 --external-gateway ext-netardana >
openstack network list
Specify the appropriate flavor and network settings in the
caasp-multi-master-environment.yaml
file.
Set master_count
to the desired number in the
caasp-multi-master-environment.yaml
file. The master
count must be set to an odd number of nodes.
master_count: 3
Create a stack in Heat by passing the template, environment file, and parameters:
ardana >
openstack stack create -t caasp-multi-master-stack.yaml \
-e caasp-multi-master-environment.yaml --parameter image=CaaSP-3 caasp-multi-master-stack
Find the floating IP address of the load balancer. This is necessary for accessing the Velum SUSE CaaS Platform dashboard.
ardana >
openstack loadbalancer list --provider
From the output, copy the id
and enter it in the
following command as shown in the following example:
ardana >
openstack loadbalancer show id

The load balancer floating ip address is 10.84.65.37
Accessing the Velum SUSE CaaS Platform Dashboard
After the stack has been created, the Velum SUSE CaaS Platform dashboard runs on the admin node. You can access it using the floating IP address of the admin node.
Create an account and follow the steps in the Velum SUSE CaaS Platform dashboard to complete the SUSE CaaS Platform installation.

By default the Heat SUSE CaaS Platform playbook downloads the SUSE CaaS Platform image from http://download.suse.de/install/SUSE-CaaSP-3-GM/SUSE-CaaS-Platform-3.0-for-OpenStack-Cloud.x86_64-3.0.0-GM.qcow2. If this URL is not accessible, the SUSE CaaS Platform image can be downloaded from https://download.suse.com/Download?buildid=z7ezhywXXRc and copied to the deployer.
To create a SUSE CaaS Platform cluster and pass the path to the downloaded image, run the following commands:
ardana >
cd ~/scratch/ansible/next/ardana/ansibleardana >
ansible-playbook -i hosts/localhost heat-caasp-deploy.yml -e "caasp_image_tmp_path=~/SUSE-CaaS-Platform-3.0-for-OpenStack-Cloud.x86_64-3.0.0-GM.qcow2"

ardana >
cd ~/scratch/ansible/next/ardana/ansibleardana >
ansible-playbook -i hosts/localhost heat-caasp-deploy.yml -e "caasp_image_tmp_path=caasp_image_tmp_path=~/SUSE-CaaS-Platform-3.0-for-OpenStack-Cloud.x86_64-3.0.0-GM.qcow2 caasp_stack_name=caasp_multi-master caasp_stack_yaml_file=caasp-multi-master-stack.yaml caasp_stack_env_yaml_file=caasp-multi-master-environment.yaml"
When deploying a CaaaSP cluster using SUSE CaaS Platform OpenStack Heat
templates, the following CPI parameters can be set in
caasp-environment.yaml
or
caasp-multi-master-environment.yaml
.
The URL of the Keystone API used to authenticate the user. This value can be found on OpenStack Dashboard under › › (for example, https://api.keystone.example.net:5000/v3/)
Name of the domain the user belongs to
Name of the project the user belongs to. This is the project where the resources will be created.
Name of the region to use when running a multi-region OpenStack cloud. The region is a general division of an OpenStack deployment.
Username of a valid user that has been set in Keystone. Default: admin
Password of a valid user that has been set in Keystone.
Neutron load balancer monitoring max retries. Default: 3
Cinder Block Storage API version. Possible values are v1, v2 , v3 or auto. Default: auto
Ignore Cinder and Nova availability zones. Default: true
When the SUSE CaaS Platform cluster has been deployed by the Heat templates, the
Velum dashboard on the admin node
(https://ADMIN-NODE-IP/) will have entries for
OpenStack
settings form will show the values that were set in the
caasp-environment.yaml
or
caasp-multi-master-environment.yaml
files.
After the SUSE CaaS Platform cluster comes up, install the latest SUSE CaaS Platform 3.0 Maintenance Update using the following steps:
Spin up a SUSE CaaS Platform cluster using Heat templates following the instructions in Section 21.1, “SUSE CaaS Platform Heat Installation Procedure”. Do not go through the bootstrapping steps, because the SUSE CaaS Platform Maintenance Update (MU) must be applied first. After the maintenance update process below succeeds, return to the SUSE CaaS Platform installation instructions and follow the admin node bootstrapping steps.
Apply the SUSE CaaS Platform 3.0 Maintenance Update with the following steps:
Log in to each node and add the update repository.
ardana >
sudo zypper ar http://nu.novell.com/SUSE/Updates/SUSE-CAASP/3.0/x86_64/update/ caasp_update
With root privileges, run transactional-update
on each node.
Reboot each node
Verify that the Velum image packages were updated
ardana >
zypper se --detail velum-image

Upload a valid trust certificate that can validate a certificate
presented by Keystone at the specified
keystone_auth_url
in the system-wide
certificate
section of Velum. The certificate must be uploaded
to avoid bootstrapping failure with a x509: certificate signed
by unknown authority
error message.
Get SUSE Root CA certificate with the following steps:
From the RPM provided in the repos:
Add a repository for your distribution at
http://download.suse.de/ibs/SUSE:/CA/
. For
example, with openSUSE Leap
, use
http://download.suse.de/ibs/SUSE:/CA/openSUSE_Leap_15.0/SUSE:CA.repo
Install certificates and find the .pem
file.
ardana >
sudo zypper in ca-certificates-suseardana >
rpm -ql ca-certificates-suse
The path to the cert is /usr/share/pki/trust/anchors/SUSE_Trust_Root.crt.pem
In system wide certificate
during setup in Velum,
upload this certificate so you can bootstrap with CPI.
After the nodes come up, continue with the installation instructions in Section 21.1, “SUSE CaaS Platform Heat Installation Procedure” following the admin node cluster bootstrapping steps.
