Mar 9, 2025 by ADMIN 46 views

Overview

Database provisioning is a crucial aspect of project setup, allowing developers to create and configure databases with ease. In this article, we will explore the implementation of database provisioning functionality, including the addition of flags for the go create command, support for multiple database types, and configuration options for database settings.

Description

Database provisioning enables developers to create a new project with a database in a single command. This feature is essential for rapid development and deployment, as it saves time and effort in setting up databases. The goal of this implementation is to provide a seamless experience for developers, allowing them to focus on writing code rather than configuring databases.

Tasks

Implement Database Provisioning Flags for `go create` Command

To begin, we need to add flags for the go create command that will enable database provisioning. These flags will allow developers to specify the type of database they want to create and configure its settings.

// flags.go
package main

import (
	"flag"
	"fmt"
)

var (
	dbType = flag.String("db-type", "", "Database type (PostgreSQL, SQLite, MSSQL)")
	dbName = flag.String("db-name", "", "Database name")
	dbUser = flag.String("db-user", "", "Database username")
	dbPass = flag.String("db-pass", "", "Database password")
)

Support Multiple Database Types

We will support three database types: PostgreSQL, SQLite, and MSSQL. Each type will have its own initialization script and configuration options.

// db_types.go
package main

import (
	"fmt"
)

type DBType string

const (
	PostgreSQL DBType = "PostgreSQL"
	SQLite     DBType = "SQLite"
	MSSQL      DBType = "MSSQL"
)

Add Configuration Options for Database Settings

We will add configuration options for database settings, including database name, username, and password.

// db_config.go
package main

import (
	"fmt"
)

type DBConfig struct {
	Name  string
	User  string
	Pass  string
}

Create Database Initialization Scripts for Each Type

We will create initialization scripts for each database type, which will be executed when the database is created.

// init_scripts.go
package main

import (
	"fmt"
)

func initPostgreSQLDB(dbConfig *DBConfig) error {
	// Initialize PostgreSQL database
	return nil
}

func initSQLiteDB(dbConfig *DBConfig) error {
	// Initialize SQLite database
	return nil
}

func initMSSQLDB(dbConfig *DBConfig) error {
	// Initialize MSSQL database
	return nil
}

Implement Connection Information Storage

We will store connection information securely and accessibly, using a standardized format.

// connection.go
package main

import (
	"fmt"
	"encoding/json"
)

type Connection struct {
	Host     string `json:"host"`
	Port     int    `json:"port"`
	Username string `json:"username"`
	Password string `json:"password"`
}

func storeConnectionInfo(connection *Connection) error {
	// Store connection information securely
	return nil
}

Acceptance Criteria

User Can Create a Project with a Database in One Command

The user should be able to create a project with a database in a single command, using the go create command with the added flags.

go create -db-type=PostgreSQL -db-name=mydb -db-user=myuser -db-pass=mypass

Multiple Database Types Are Supported

The implementation should support multiple database types, including PostgreSQL, SQLite, and MSSQL.

Database Is Properly Initialized and Configured

The database should be properly initialized and configured, using the initialization scripts for each type.

Connection Information Is Stored Securely and Accessibly

The connection information should be stored securely and accessibly, using a standardized format.

Clear Feedback on Database Creation Success or Failure

The implementation should provide clear feedback on database creation success or failure, using a standardized error message format.

Implementation Notes

Check for Database Client Installations Before Attempting to Create

Before attempting to create a database, we should check if the required database client is installed.

// check_client.go
package main

import (
	"fmt"
)

func checkClientInstalled(client string) error {
	// Check if client is installed
	return nil
}

For PostgreSQL and MSSQL, Validate Server Connection Before Proceeding

For PostgreSQL and MSSQL, we should validate the server connection before proceeding with the database creation.

// validate_connection.go
package main

import (
	"fmt"
)

func validatePostgreSQLConnection(host string, port int, username string, password string) error {
	// Validate PostgreSQL connection
	return nil
}

func validateMSSQLConnection(host string, port int, username string, password string) error {
	// Validate MSSQL connection
	return nil
}

For SQLite, Create Appropriate Directory Structure and Initial .db File

For SQLite, we should create the appropriate directory structure and initial .db file.

// init_sqlite.go
package main

import (
	"fmt"
)

func initSQLiteDB(dbConfig *DBConfig) error {
	// Initialize SQLite database
	return nil
}

Consider Adding Templates for Common Database Schemas

We should consider adding templates for common database schemas, to simplify the database creation process.

// templates.go
package main

import (
	"fmt"
)

func createTemplate(dbType DBType) error {
	// Create template for database schema
	return nil
}

Store Connection Strings in a Standardized Format

We should store connection strings in a standardized format, to simplify the connection process.

// connection.go
package main

import (
	"fmt"
	"encoding/json"
)

type Connection struct {
	Host     string `json:"host"`
	Port     int    `json:"port"`
	Username string `json:"username"`
	Password string `json:"password"`
}

func storeConnectionInfo(connection *Connection) error {
	// Store connection information securely
	return nil
}

Consider Adding Docker Support for Containerized Databases

We should consider adding Docker support for containerized databases, to simplify the database creation process.

// docker.go
package main

import (
	"fmt"
)

func createDockerContainer(dbType DBType) error {
	// Create Docker container for database
	return nil
}

Add Option to Create Database Migration Files

We should add an option to create database migration files, to simplify the database migration process.

// migrations.go
package main

import (
	"fmt"
)

func createMigrationFile(dbConfig *DBConfig) error {
	// Create migration file for database
	return nil
}

Provide Settings for Database Name, Username, Password Options

We should provide settings for database name, username, and password options, to simplify the database creation process.

// db_config.go
package main

import (
	"fmt"
)

type DBConfig struct {
	Name  string
	User  string
	Pass  string
}

Consider Implementing Database Backup/Restore Functionality

We should consider implementing database backup/restore functionality, to simplify the database management process.

// backup_restore.go
package main

import (
	"fmt"
)

func backupDatabase(dbConfig *DBConfig) error {
	// Backup database
	return nil
}

func restoreDatabase(dbConfig *DBConfig) error {
	// Restore database
	return nil
}
