23 Installing a Stand-Alone Cloud Lifecycle Manager #
23.1 Important Notes #
For information about when to use the GUI installer and when to use the command line (CLI), see Chapter 13, Overview.
Review the Chapter 2, Hardware and Software Support Matrix that we have listed.
Review the release notes to make yourself aware of any known issues and limitations.
The installation process can occur in different phases. For example, you can install the control plane only and then add Compute nodes afterwards if you would like.
If you run into issues during installation, we have put together a list of Chapter 36, Troubleshooting the Installation you can reference.
Make sure all disks on the system(s) are wiped before you begin the install. (For swift, refer to Section 11.6, “Swift Requirements for Device Group Drives”.)
There is no requirement to have a dedicated network for OS-install and system deployment, this can be shared with the management network. More information can be found in Chapter 9, Example Configurations.
The terms deployer and Cloud Lifecycle Manager are used interchangeably. They refer to the same nodes in your cloud environment.
When running the Ansible playbook in this installation guide, if a runbook fails you will see in the error response to use the
--limit
switch when retrying a playbook. This should be avoided. You can simply re-run any playbook without this switch.DVR is not supported with ESX compute.
When you attach a cinder volume to the VM running on the ESXi host, the volume will not get detected automatically. Make sure to set the image metadata vmware_adaptertype=lsiLogicsas for image before launching the instance. This will help to discover the volume change appropriately.
The installation process will create several OpenStack roles. Not all roles will be relevant for a cloud with swift only, but they will not cause problems.
23.2 Prepare for Cloud Installation #
Review the Chapter 14, Pre-Installation Checklist about recommended pre-installation tasks.
Prepare the Cloud Lifecycle Manager node. The Cloud Lifecycle Manager must be accessible either directly or via
ssh
, and have SUSE Linux Enterprise Server 12 SP4 installed. All nodes must be accessible to the Cloud Lifecycle Manager. If the nodes do not have direct access to online Cloud subscription channels, the Cloud Lifecycle Manager node will need to host the Cloud repositories.If you followed the installation instructions for Cloud Lifecycle Manager server (see Chapter 15, Installing the Cloud Lifecycle Manager server), SUSE OpenStack Cloud software should already be installed. Double-check whether SUSE Linux Enterprise and SUSE OpenStack Cloud are properly registered at the SUSE Customer Center by starting YaST and running › .
If you have not yet installed SUSE OpenStack Cloud, do so by starting YaST and running › › . Choose and follow the on-screen instructions. Make sure to register SUSE OpenStack Cloud during the installation process and to install the software pattern
patterns-cloud-ardana
.tux >
sudo zypper -n in patterns-cloud-ardanaEnsure the SUSE OpenStack Cloud media repositories and updates repositories are made available to all nodes in your deployment. This can be accomplished either by configuring the Cloud Lifecycle Manager server as an SMT mirror as described in Chapter 16, Installing and Setting Up an SMT Server on the Cloud Lifecycle Manager server (Optional) or by syncing or mounting the Cloud and updates repositories to the Cloud Lifecycle Manager server as described in Chapter 17, Software Repository Setup.
Configure passwordless
sudo
for the user created when setting up the node (as described in Section 15.4, “Creating a User”). Note that this is not the userardana
that will be used later in this procedure. In the following we assume you named the usercloud
. Run the commandvisudo
as userroot
and add the following line to the end of the file:CLOUD ALL = (root) NOPASSWD:ALL
Make sure to replace CLOUD with your user name choice.
Set the password for the user

su - ardanaPlace a copy of the SUSE Linux Enterprise Server 12 SP4
.iso
in theardana
home directory,var/lib/ardana
, and rename it tosles12sp4.iso
.Install the templates, examples, and working model directories:
ardana >
/usr/bin/ardana-init
23.3 Configuring Your Environment #
You have already configured an input model for a stand-alone deployer in a previous step (Chapter 20, Preparing for Stand-Alone Deployment). Now that input model needs to be moved into the setup directory.
ardana >
cp -r ~/openstack/examples/entry-scale-kvm-stand-alone-deployer/* \ ~/openstack/my_cloud/definition/(Optional) You can use the
ardanaencrypt.py
script to encrypt your IPMI passwords. This script uses OpenSSL.Change to the Ansible directory:
ardana >
cd ~/openstack/ardana/ansibleEnter the encryption key into the following environment variable:
ardana >
export ARDANA_USER_PASSWORD_ENCRYPT_KEY=<encryption key>Run the python script below and follow the instructions. Enter a password that you want to encrypt.
ardana >
./ardanaencrypt.pyTake the string generated and place it in the
ilo-password
field in your~/openstack/my_cloud/definition/data/servers.yml
file, remembering to enclose it in quotes.Repeat the above for each server.
NoteBefore you run any playbooks, remember that you need to export the encryption key in the following environment variable:
export ARDANA_USER_PASSWORD_ENCRYPT_KEY=<encryption key>
Commit your configuration to the local git repo (Chapter 22, Using Git for Configuration Management), as follows:
ardana >
cd ~/openstack/ardana/ansibleardana >
git add -Aardana >
git commit -m "My config or other commit message"ImportantThis step needs to be repeated any time you make changes to your configuration files before you move on to the following steps. See Chapter 22, Using Git for Configuration Management for more information.
23.4 Running the Configuration Processor #
Once you have your configuration files setup, you need to run the configuration processor to complete your configuration.
When you run the configuration processor, you will be prompted for two
passwords. Enter the first password to make the configuration processor
encrypt its sensitive data, which consists of the random inter-service
passwords that it generates and the ansible group_vars
and host_vars
that it produces for subsequent deploy
runs. You will need this password for subsequent Ansible deploy and
configuration processor runs. If you wish to change an encryption password
that you have already used when running the configuration processor then
enter the new password at the second prompt, otherwise just press
Enter to bypass this.
Run the configuration processor with this command:
ardana >
cd ~/openstack/ardana/ansibleardana >
ansible-playbook -i hosts/localhost config-processor-run.yml
For automated installation (for example CI), you can specify the required passwords on the ansible command line. For example, the command below will disable encryption by the configuration processor:
ardana >
ansible-playbook -i hosts/localhost config-processor-run.yml \
-e encrypt="" -e rekey=""
If you receive an error during this step, there is probably an issue with one or more of your configuration files. Verify that all information in each of your configuration files is correct for your environment. Then commit those changes to Git using the instructions in the previous section before re-running the configuration processor again.
For any troubleshooting information regarding these steps, see Section 36.2, “Issues while Updating Configuration Files”.
23.5 Configuring TLS #
This section is optional, but recommended, for a SUSE OpenStack Cloud installation.
After you run the configuration processor the first time, the IP addresses
for your environment will be generated and populated in the
~/openstack/my_cloud/info/address_info.yml
file. At
this point, consider whether to configure TLS and set up an SSL certificate
for your environment. Please read Chapter 41, Configuring Transport Layer Security (TLS) before proceeding
for how to achieve this.
23.6 Deploying the Cloud #
Use the playbook below to create a deployment directory:
cd ~/openstack/ardana/ansible ansible-playbook -i hosts/localhost ready-deployment.yml
[OPTIONAL] - Run the
wipe_disks.yml
playbook to ensure all of your non-OS partitions on your nodes are completely wiped before continuing with the installation. Thewipe_disks.yml
playbook is only meant to be run on systems immediately after runningbm-reimage.yml
. If used for any other case, it may not wipe all of the expected partitions.If you are using fresh machines this step may not be necessary.
ardana >
cd ~/scratch/ansible/next/ardana/ansibleardana >
ansible-playbook -i hosts/verb_hosts wipe_disks.ymlIf you have used an encryption password when running the configuration processor use the command below and enter the encryption password when prompted:
ardana >
ansible-playbook -i hosts/verb_hosts wipe_disks.yml --ask-vault-passRun the
site.yml
playbook below:ardana >
cd ~/scratch/ansible/next/ardana/ansibleardana >
ansible-playbook -i hosts/verb_hosts site.ymlIf you have used an encryption password when running the configuration processor use the command below and enter the encryption password when prompted:
ardana >
ansible-playbook -i hosts/verb_hosts site.yml --ask-vault-passNoteThe step above runs
osconfig
to configure the cloud andardana-deploy
to deploy the cloud. Therefore, this step may run for a while, perhaps 45 minutes or more, depending on the number of nodes in your environment.Verify that the network is working correctly. Ping each IP in the
/etc/hosts
file from one of the controller nodes.
For any troubleshooting information regarding these steps, see Section 36.3, “Issues while Deploying the Cloud”.
23.7 Installing OpenStack Assets on the Stand-alone Deployer #
The OpenStack CLI and OpenStack clients will not be installed automatically. If you require access to these clients, you will need to follow the procedure below to add the appropriate software.
[OPTIONAL] To confirm that OpenStack clients have not been installed, connect to your stand-alone deployer and try to use the OpenStack CLI:
ardana >
source ~/keystone.osrcardana >
openstack project list -bash: openstack: command not foundEdit the configuration file containing details of your Control Plane,
~/openstack/my_cloud/definition/data/control_plane.yml
Locate the stanza for the cluster where you want to install the client(s). This will look like the following extract:
clusters: - name: cluster0 cluster-prefix: c0 server-role: LIFECYCLE-MANAGER-ROLE member-count: 1 allocation-policy: strict service-components: - ntp-server - lifecycle-manager
Choose the client(s) you wish to install from the following list of available clients:
- barbican-client - ceilometer-client - cinder-client - designate-client - glance-client - heat-client - ironic-client - keystone-client - magnum-client - manila-client - monasca-client - neutron-client - nova-client - ntp-client - octavia-client - openstack-client - swift-client
Add the client(s) to the list of
service-components
- in the following example, several OpenStack clients are added to the stand-alone deployer:clusters: - name: cluster0 cluster-prefix: c0 server-role: LIFECYCLE-MANAGER-ROLE member-count: 1 allocation-policy: strict service-components: - ntp-server - lifecycle-manager - openstack-client - cinder-client - designate-client - glance-client - heat-client - ironic-client - keystone-client - neutron-client - nova-client - swift-client - monasca-client - barbican-client
Commit the configuration changes:
ardana >
cd ~/openstack/ardana/ansibleardana >
git add -Aardana >
git commit -m "Add explicit client service deployment"Run the configuration processor, followed by the
ready-deployment
playbook:ardana >
cd ~/openstack/ardana/ansibleardana >
ansible-playbook -i hosts/localhost config-processor-run.yml -e encrypt="" \ -e rekey=""ardana >
ansible-playbook -i hosts/localhost ready-deployment.ymlAdd the software for the clients using the following command:
ardana >
cd ~/scratch/ansible/next/ardana/ansibleardana >
ansible-playbook -i hosts/verb_hosts clients-upgrade.ymlCheck that the software has been installed correctly. Using the same test that was unsuccessful before, connect to your stand-alone deployer and try to use the OpenStack CLI:
ardana >
source ~/keystone.osrcardana >
openstack project listYou should now see a list of projects returned:
ardana >

23.8 Post-Installation Verification and Administration #
We recommend verifying the installation using the instructions in Chapter 38, Post Installation Tasks.
There are also a list of other common post-installation administrative tasks listed in the Chapter 44, Other Common Post-Installation Tasks list.
