Finance Service Configuration

Overview

This document describes the steps to be followed to set up a new instance of Finance. When a new state or city is to be set up, there are some activities to be executed in a defined order. Setting up an instance of an application server and configuration changes etc are a few of the key activities.

Technical Prerequisites

Prior Knowledge of Java/J2EE.
Prior Knowledge of Spring and Hibernate
Prior knowledge of Maven
Prior knowledge of Git.

Hardware/Software Prerequisites

Maven v3.2.x
PostgreSQL v9.6
Customized Wildfly Image
Git 2.8.3
JDK 8 update 112 or higher
Create subdomains under the main domain for each of the cities that are to be set up
Create a schema per city in the database

Configurations and Setup

The Co-existence repository is the base repository for the finance product and the client-specific data needs to be defined in the Client implementation repository

How to set up a client implementation repository

Fork and create a client implementation repository from Client implementation repository to keep client-specific data and configurations.
Any configurations and data specific to the client should be added in the client repository.

Application Configuration

The default application configurations of the finance service are present in the application configuration file. To enable or disable any feature, either update the values in the application configuration file or the override configuration file.
The override configuration is the template and the values for the template are present either in the finance service values yaml file or in the environment named yaml file. The finance service values yaml is the common file to override the default values and the changes made to this file are applicable for all environments (dev, qa, uat, prod etc).
Any specific configuration change is required for any specific environment then update the environment named yaml file.

Sample environment named yaml files for your reference

https://github.com/egovernments/Train-InfraOps/blob/master/helm/environments/qa.yaml
https://github.com/egovernments/Train-InfraOps/blob/master/helm/environments/uat.yaml

Database configuration

Add or update the db url in the environment specific file using the below property

erp-db-url: "jdbc:postgresql://egov-dev-db.ctm6jbmr5mnj.ap-south-1.rds.amazonaws.com:5432/finance_qa_db"

Update the db username and password, which are configured in the environment named secrets yaml file.

For example, for the qa environment, update the qa-secrets.yaml

secrets:
        db:
            username: <username value> 
            password:  <password value>

Set up a schema-based multi-tenant database

Finance co-existence service uses schema-based multi-tenancy, this means there will be one schema present for a city. The following are the configuration changes to set up this kind of database.

Enable multi-tenancy by enabling the following property

multitenancy: true

Each ULB is enabled by adding a schema name and domain name. Schema names should follow a naming standard, It should be the same as that of the city name.
Each ULB can be configured by adding an entry like tenant.<domain_name>=schema_name (city_name)
The default tenants are configured in the finance service yaml file using the below configuration.

tenants: |
 tenant.citya.egovernments.org=citya
 tenant.cityb.egovernments.org=cityb

To override and have separate tenants for a specific environment then update the environment-specific file like below.

FinanceTenants: |
 tenant.citya.egovernments.org=citya
 tenant.cityb.egovernments.org=cityb

Here citya.egovernments.org, cityb.egovernments.org are the domains and citya, cityb are the schemas/tenants.

Example environment specific configuration file for your reference.

Update the domainurl in the eg_city table.
Domain URL value should be the same as configured tenant domain_name Ex:

For citya, domain url should be citya.egovernments.org
For cityb, domain url should be cityb.egovernments.org

Database migration settings

The default database migration configurations are present in the application configuration file.

#Enable/Disable flyway migration
db.migration.enabled=true

#Enable/Disable flyway migration validation
db.flyway.validateon.migrate=false

#Enable/Disable repairing of flyway migration checksum
db.flyway.migration.repair=false

#Various flyway migration sql script file paths
db.flyway.main.migration.file.path=classpath:/db/migration/main/
db.flyway.sample.migration.file.path=classpath:/db/migration/sample/
db.flyway.tenant.migration.file.path=classpath:/db/migration/%s/
db.flyway.statewide.migration.file.path=classpath:/db/migration/statewide/

#Enable/Disable to run migration sql's inside "statewide" migration folder (resources/db/migration/statewide)
statewide.migration.required=false

#Schema name where statewide migration to be executed, value must be your default schema name (see default.schema.name)
statewide.schema.name=generic

#Enable/Disable dev mode, this must be set to false in all non dev environments
dev.mode=false

Override the default values by updating the properties either in the finance service values yaml file or the environment-specific yaml file. The following are different properties.

# Enable/Disable to execute the sample sql scripts.
dev_mode: false
# Enable/Disable flyway migration validation
db_flyway: true
#Enable/Disable to run migration sql's inside "statewide" migration folder (resources/db/migration/statewide)
statewide_migration: true
#Enable or Disable Multitenancy
multitenancy: true

System Integration User Details Configuration

Configure the following property either in the finance service values yaml file or the environment-specific yaml file.

Systemintegration: |
 si.microservice.user=${si-microservice-user}
 si.microservice.password=${si-microservice-password}
 si.microservice.usertype=SYSTEM
 si.microservice.scope=read
 si.microservice.granttype=password
 
 env: |
  - name: si-microservice-password
    valueFrom:
      secretKeyRef:  
        name: egov-si-microservice
        key: si-microservice-password
  - name: si-microservice-user
    valueFrom:
      secretKeyRef:  
        name: egov-si-microservice
        key: si-microservice-user

Add one user in the system for system integration - SIFINANCE mapped with role SYS_INTEGRATOR_FINANCE by using the user service createnovalidate API.
