#KingbaseES

#Introduction

KingbaseES can be used as the NocoBase main database. It stores NocoBase system-table data and business data in the main data source. Configure it when deploying NocoBase; it cannot be deleted after the application is running.

To connect an existing KingbaseES database as an external database, see External KingbaseES.

#Installation

#Use as the main database

Follow Install a NocoBase application. The main difference is the database environment variables.

#Environment variables

Add or update these database variables in .env:

# Adjust DB parameters for your environment.
DB_DIALECT=kingbase
DB_HOST=localhost
DB_PORT=54321
DB_DATABASE=kingbase
DB_USER=nocobase
DB_PASSWORD=nocobase

#Docker installation

  nocobase:
    driver: bridge

    restart: always

    environment:

    ports:

  kingbase:
    image: registry.cn-shanghai.aliyuncs.com/nocobase/kingbase:v009r001c001b0030_single_x86
    platform: linux/amd64
    restart: always
    privileged: true
    networks: [nocobase]
    volumes:
      - ./storage/db/kingbase:/home/kingbase/userdata
    environment:
      ENABLE_CI: no
      DB_USER: nocobase
      DB_PASSWORD: nocobase
      DB_MODE: pg
      NEED_START: yes
    command: ["/usr/sbin/init"]

APP_KEY is used for user tokens and similar application secrets. Changing it invalidates existing tokens; use a random value and store it safely. The kingbase service is intended only for local evaluation. DB_MODE must be pg.

#Install with create-nocobase-app

yarn create nocobase-app my-nocobase-app -d kingbase \
  -e DB_HOST=localhost \
  -e DB_PORT=54321 \
  -e DB_DATABASE=kingbase \
  -e DB_USER=nocobase \
  -e DB_PASSWORD=nocobase \
  -e TZ=Asia/Shanghai

#Use as an external database

For configuration entry points, connection parameters, and synchronization rules when using KingbaseES as an external database, see External KingbaseES.

#Usage

KingbaseES main data sources use PostgreSQL compatibility mode. For everyday management, see PostgreSQL main data source.

1. Select or enter KingbaseES connection settings when deploying NocoBase.
2. After NocoBase starts, open Data source management, select Main, and manage collections and fields.
3. Use Sync from database to connect tables that already exist in the main database.
4. Use Collections and Collection fields to choose Field types and Field interfaces.

#Field type mapping

When you create a field in NocoBase, NocoBase creates the corresponding KingbaseES field. When you synchronize an existing table, NocoBase applies PostgreSQL-compatible mapping to select a Field type and Field interface.

For common configuration, see Main database.
