Expanding a Signals Data Factory Cluster

Applies to 

Managed Kubernetes
 
Adding nodes with no additional storage

1. The new nodes must meet all the pre-requisites of a SDF node
2. Edit cluster-configuration.yaml, add the IP addresses for the new nodes and set corereplicas to the new number of nodes.
3. Run ./scripts/deploy-sdf.sh 

Bare Metal Kubernetes
 
Adding nodes with no additional storage
The new nodes must meet all the pre-requisites of a SDF node

1. You must have the cluster.rkestate file from the original deployment.
2. Edit cluster-configuration.yaml and add the IP addresses for the new nodes.
3. Edit ./scripts/deploy-sdf-storage-k8s.sh and change deployStorage=true to deployStorage=false in both places.    --- Note: deployStorage=false should be the use in case of no additional storage
4. Run ./scripts/deploy-sdf-storage-k8s.sh —skipRequirements

Adding new nodes with storage on each new node
Same as above but skip step 3. Important, if storage is in use, node cannot be removed.
