- Add an Openstack Credential
  Add an OpenStack Cloud account to NavOps you can later add a cloud credential in NavOps.
- Prerequisites for Openstack Cloud Scaling
  Components that are necessary for OpenStack cloud scaling.
- Create an Openstack Cloud Environment
  Create an OpenStack cloud environment so that workload manager execution nodes can be deployed in the cloud. Provide information about the cloud environment such as region, OS image, subnet id, security group id and tags
- Create an Openstack Node Class
  Create an Openstack Node Class so that workload manager execution nodes can be deployed in the cloud. A Node Class provides the infrastructure for the workload to run on. It is a template of an instance which defines benchmarked hardware. A Node Class exists in an Environment and consists of instance type, OS image, security group id, tags, SSH-keys and cloud-init script.
Add, Register, and Deploy a Cluster
After creating a cluster, it has to be registered by installing the NavOps CLI and agent. You can add node configurations containing custom resources and scripts and deploy the cluster.
Node Configurations
Node configurations enable you to customize a node associated with a cluster. Compared to operations performed via the cloud-init script these configurations are managed on the WLM server increasing flexibility and security. Node configurations are supported for PBS, Grid Engine and Slurm clusters.
Deploy Cloud Nodes Manually
Deploy nodes manually (without the intervention of the workload manager) for testing purposes or when your site wants to keep nodes deployed for an indeterminate amount of time.
Undeploy Cloud Nodes Manually
Undeploy cloud nodes when they are no longer needed.
Automate Cloud Scaling for Accelerator
Create rules to automatically scale-up and scale-down deployment of nodes on the cloud.
Automate Cloud Scaling for PBS Professional
Create rules to automatically scale-up and scale-down deployment of nodes on the cloud. Use node configuration to customize a node associated with a PBS cluster.
Automate Cloud Scaling for Grid Engine
Create rules to automatically scale-up and scale-down deployment of nodes on the cloud. Use node configuration to customize a node associated with a Grid Engine cluster.
Automate Cloud Scaling for Slurm
Create rules to automatically scale-up and scale-down deployment of nodes on the cloud. Use node configuration to customize a node associated with a Slurm cluster.
Generate API Keys
NavOps uses API keys to connect the NavOps server, WLM agent, head node and cloud nodes. Each cluster has a dedicated API KEY, if you would like to generate additional key please use the following instructions. The key is generated and displayed once. Make sure you save it as you won't be able to access it again. The key is generated for a specific cluster. The key is set on the deployed nodes. It is also present in the NavOps agent on the head node and the MoMs. The default expiry date of the key is one year. When the key expires, you can generate another one and replace the key manually on the head node.
Cost Center
Cost centers provide visibility of expenditure to dynamically manage cloud operations and plan ahead. Cost centers are associated with node delpoyments. The limits defined in the cost center are checked before deploying nodes. The estimated costs accrued by cost centers are displayed visually as well as in a table.
Accounting
The accounting dashboard provides a set of reports containing charts and tables tracking Burn Rate, Core Count, Node Count and Total Cost for the Cloud connector, Cloud credentials, Cloud environment, Node class and Cluster datasets. These reports can be produced for a custom date and time range or a set of preset date and time ranges.
Known Issues

Add an Openstack Credential

Add an OpenStack Cloud account to NavOps you can later add a cloud credential in NavOps.

For information about logging into the OpenStack Dashboard see Log in to the dashboard.

Open the OpenStack RC file to get information that's necessary to create an OpenStack Cloud account. This file contains tenant-specific environment variables and environment variables that are necessary to run OpenStack command-line clients.

Login to NavOps.
Go to Clouds, and then select Credentials.
Click Add Cloud Credentials
Select Openstack.
For Name, enter any name for the cloud account.
The name can be anything meaningful to your organization, e.g., openstack_cloudaccount.
Open a second browser window.
Login to the Openstack Dashboard as a user with Openstack admin or member privileges.
Click > OpenStack RC File.
