WSO2 Business Rules Manager uses ruleTemplates within templateGroups, to derive business rules from. Each ruleTemplate will have a UUID - that is used to uniquely identify itself. When a ruleTemplate is specified under a worker node; SiddhiApps derived in business rules created out of that ruleTemplate will be deployed in the specified worker node.

1. Open the deployment.yaml file in the <WSO2SP_HOME>/conf/dashboard directory.

2. Deployment configurations for the Business Rules Manager are specified under wso2.business.rules.manager. Provide the URL(s) of worker node(s) that is/are available to deploy SiddhiApps, under deployment_configs in the <HOST_NAME>:<PORT> format.

   Code Block
   language powershell
   deployment_configs: - <NODE1_HOST_NAME>:<NODE1_PORT> <NODE2_HOST_NAME>:<NODE2_PORT>

   Eg:

   Code Block
   language powershell
   deployment_configs: - localhost:9090 10.100.4.140:9090

3. List down the UUIDs of required rule templates under each node. This results in Siddhi applications created out of the business rules derived from those templates being deployed in the required nodes.

   Code Block
   language powershell
   deployment_configs: - <NODE1_HOST_NAME>:<NODE1_PORT>: - ruleTemplate1_UUID - ruleTemplate2_UUID - ruleTemplate3_UUID

   
   

   e.g.,

   Code Block
   language powershell
   deployment_configs: - localhost:9090: - sweet-production-kpi-analysis - stock-exchange-input - stock-exchange-output

4. If required, you can enter a specific rule template under multiple nodes as shown below.

   Info
   Before entering a specific rule template under multiple node, make sure that you have selected Many for the Instance Count field of the template. For more information, see Creating a Business Rule Template.

   Code Block
   language powershell
   deployment_configs: - <NODE1_HOST_NAME>:<NODE1_PORT>: - ruleTemplate1_UUID - ruleTemplate2_UUID - ruleTemplate3_UUID <NODE2_HOST_NAME>:<NODE2_PORT>: - ruleTemplate1_UUID - ruleTemplate3_UUID <NODE3_HOST_NAME>:<NODE3_PORT>: - ruleTemplate2_UUID - ruleTemplate3_UUID - ruleTemplate4_UUID

   e.g.,

   Code Block
   language powershell
   deployment_configs: - localhost:9090: - sweet-production-kpi-analysis - stock-exchange-input - stock-exchange-output 10.100.40.169:9090: - identifying-continuous-production-decrease - sweet-production-kpi-analysis

   Note that the rule template with the sweet-production-kpi-analysis UUIDhas been configured under two worker nodes. As indicated by this, if a business rule is derived from sweet-production-kpi-analysis, Siddhi Applications created from it are deployed in both the nodes.

5. Specify the username and password that are common for all the worker nodes.

   Code Block
   language powershell
   username: admin password: admin

   
   

   The complete deployment configuration for Business Rules looks as follows.

   Code Block
   language powershell
   wso2.business.rules.manager: datasource: BUSINESS_RULES_DB deployment_configs: - localhost:9090: - stock-data-analysis - stock-exchange-input - stock-exchange-output - identifying-continuous-production-decrease - sweet-production-kpi-analysis username: admin password: admin
