Install StarlingX OpenStack

These instructions assume that you have completed the following OpenStack-specific configuration tasks that are required by the underlying StarlingX Kubernetes platform:

• All nodes have been labeled appropriately for their OpenStack role(s).

• The vSwitch type has been configured.

• The nova-local volume group has been configured on any node’s host, if running the compute function.

Install application manifest and helm-charts

1. Modify the size of the docker_lv filesystem. By default, the size of the docker_lv filesystem is 30G, which is not enough for stx-openstack installation. Use the host-fs-modify CLI to increase the filesystem size.

   The syntax is:

   system host-fs-modify <hostname or id> <fs name=size>
   

   Where:

   • hostname or id is the location where the file system will be added.

   • fs name is the file system name.

   • size is an integer indicating the file system size in Gigabytes.

   For example:

   system host-fs-modify controller-0 docker=60
   

2. Get the latest StarlingX OpenStack application (stx-openstack) manifest and helm charts. Use one of the following options:

   • Private StarlingX build. See Build StarlingX OpenStack application for details.

   • Public download from the StarlingX mirror.

     After you select a release, helm charts are located in centos/outputs/helm-charts.

3. Load the stx-openstack application’s package into StarlingX. The tarball package contains stx-openstack’s FluxCD manifest and stx-openstack’s set of helm charts. For example:

   system application-upload stx-openstack-<version>-centos-stable-versioned.tgz

   This will:

   • Load the FluxCD manifest and helm charts.

   • Internally manage helm chart override values for each chart.

   • Automatically generate system helm chart overrides for each chart based on the current state of the underlying StarlingX Kubernetes platform and the recommended StarlingX configuration of OpenStack services.

4. Apply the stx-openstack application in order to bring StarlingX OpenStack into service. If your environment is preconfigured with a proxy server, then make sure HTTPS proxy is set before applying stx-openstack.

   system application-apply stx-openstack

   Note

   To set the HTTPS proxy at bootstrap time, refer to Ansible Bootstrap Configurations.

   To set the HTTPS proxy after installation, refer to Docker Proxy Configuration.

5. Wait for the activation of stx-openstack to complete.

   This can take 5-10 minutes depending on the performance of your host machine.

   Monitor progress with the command:

   watch -n 5 system application-list
