Add an autoscaling cluster to SolarCloud|
To add an autoscaling cluster to your cloud:
- Go to your Control Panelâ€™s Load Balancers menu
- Click the Add a balancer button
- On the page that follows, fill in the form that appears:
- Port - specify the port for this load balancer to run on (e.g. 9090, 8080)
- Label â€“ give a name for your load balancer instance.
- Hostname â€“ specify a host name which will identify your load balancer.
- Port Speed â€“ use the slider to set a port speed or tick the Unlimited box if required.
- Choose the Autoscaling option.
- Cluster Node Template
These settings configure the nodes that will be added to your cluster.
- Image template -Â choose a template from the drop-down box: nodes will be built on this template
- Min node amount â€“ the minimum number of nodes in this cluster
- Max node amount â€“ the maximum number of nodes in this cluster
Example: if you set Min node amount = 2 and Max node amount = 5, then the SolarCloud system will scale out the cluster up to 5 nodes, and scale in to 2 nodes if required
- Cluster Node Parameters
These are the settings for each node of a cluster. Each node added to a cluster will have the following parameters:
- Memory â€“ set the amount of memory allocated per node in MB
- CPUs â€“ set the amount of CPUs which will form each node
- CPU Priority â€“ specify CPU priority. For more info on CPU priority, refer to Create VMs KB
- Rate Limit â€“ set the port speed for a node
- Autoscale Out Parameters
Set the rules defining when the system should add more nodes to your autoscaling cluster. The system will add nodes until the limit set in the Max node amount field is reached.
- Autoscale In Parameters
Set the rules defining when the system should remove the nodes from your autoscaling cluster. The system will remove nodes until the limit set in the Min node amount field is reached.
