OpenStack Installation

OpenStack Nuances

Verify the following OpenStack nuances:

  • OpenStack newton release with at least the following service versions:
    • Cinder V2
    • Keystone V3
    • OpenStack Nova V2
    • OpenStack Networking V2
    • OpenStack Glance V2
  • The tenant and project requirements for OpenStack Cloud are as follows:
    • One Subnet with DNS servers set on the subnet 
    • Minimum Quota 
      • 11 Volumes 
      • 7 VMs 
      • 200 GB Volume Quota 
      • Flavor with at least two vCPUs and 8 GB RAM
  • Network Time Protocol (NTP) must be configured – this is important as the CloudCenter Suite installation can fail, if NTP is not configured or if it is wrongly configured.

    If you setup CloudCenter Suite in offline mode, you must provide valid NTP server details before you save your configuration.

  • Additionally, refer to your module documentation for module-specific dependencies:

Installation Process

To install the CloudCenter Suite on a new OpenStack cluster, perform the following procedure. 

  1. Verify that you have prepared your environment as listed in the OpenStack Nuances section above.
  2. Navigate to the Suite Installer Dashboard.

  3. Click New Kubernetes Cluster.

  4. Select the cloud of your choice.

  5. To connect using OpenStack cloud credentials, enter the following details.

    OpenStack DetailsDescription
    Identity UsernameThe OpenStack account username.
    Identity PasswordThe OpenStack account password.
    OpenStack Domain NameThe OpenStack account domain name.
    OpenStack Identity URLThe OpenStack authentication service URL.

  6. Click Connect.

  7. Once the connection is validated, click Next.

  8. To specify the placement properties, enter the following details.

    If you setup CloudCenter Suite in offline mode, you must provide valid NTP server details before you save your configuration.

    OpenStack DetailsDescription
    OpenStack ProjectThe OpenStack project to which the Kubernetes cluster is deployed.
    Installer Virtual ApplianceThe base image for the OpenStack installer – this must be the same image as the CloudCenter Suite virtual appliance.
    OpenStack VM FlavorThe VM specification for the Kubernetes cluster.
    OpenStack Network SubnetThe network where the VMs will be deployed.
    OpenStack Nova Availability ZoneThe compute availability zone.
    OpenStack Cinder Availability ZoneThe OpenStack volume availability zone. This field is required if the Nova availability zone is different from the Cinder Availability Zone.
    OpenStack Floating IP PoolFloating IP pool from which IP addresses are assigned to VMs.
    NTP ServersThe list of IP addresses or FQDNs of your NTP server(s) – to be used to sync VM clocks.

  9. Click InstallThe installation progress is visible on screen. 
  10. Once successful, you see the following message.

  11. You have the following options at this point:

    1. Click Take Me To Suite Admin to launch and set up the Suite Admin.

    2. Click Install Another Cluster to start another installation and go back to the homepage (Installer Dashboard).

    3. Download Kubeconfig file to connect to the launched cluster using the kubectl tool.

    4. Download SSH private key to SSH into your cluster node on private clouds – each time you launch a new cluster using the installer, the CloudCenter Suite generates a new key-pair for that cluster. 

      For private clouds, the download link for the SSH private key is available on the last page of the installer UI as displayed in the following screenshot.

  12. Be sure to switch off the installer VM. You can reuse this VM for any other purpose, for example, as an Offline Repository.
