yuniql

yuniql (yuu-nee-kel). Free and open source schema versioning and database migration engine made natively with .NET Core. Use plain SQL scripts, bulk import CSV, integrate CI/CD pipelines, zero runtime dependencies and works with windows and linux. Supports SqlServer, PostgreSql, MySql, MariaDB, Snowflake, and Amazon Redshift.

Working with CLI

Manage local db versions and run database migrations from your CLI tool. Perform local migration run or verify with uncommitted runs to test your scripts. Install yuniql CLI with Chocolatey or use alternative ways listed here https://yuniql.io/docs/install-yuniql

choco install yuniql

Run migrations for SQL Server

docker run -d -e "ACCEPT_EULA=Y" -e "[email protected]!" -p 1400:1433 -d mcr.microsoft.com/mssql/server:2017-latest
SETX YUNIQL_CONNECTION_STRING "Server=localhost,1400;Database=yuniqldb;User Id=SA;Password=[email protected]!"
SETX YUNIQL_WORKSPACE "c:\temp\yuniql-cli\samples\basic-sqlserver-sample"

git clone https://github.com/rdagumampan/yuniql.git c:\temp\yuniql-cli
cd c:\temp\yuniql-cli\samples\basic-sqlserver-sample

yuniql run -a --platform sqlserver
yuniql list --platform sqlserver

Supported databases and platform tests

Amazon Aurora, Azure Synapse and Alibaba Aspara are being evaluated/developed/tested. For running migration from docker container, see instructions here.

Platforms	Build Status	Description	Cloud Infrastructure	Documentation
sqlserver		Sql Server 2017, 2019, latest	Azure, GCP, AWS	Get started
postgresql		PostgreSql v9.6, v12.1, latest	Azure, GCP, AWS	Get started
mysql		MySql v5.7, v8.0, latest	Azure, GCP, AWS	Get started
mariadb		MariaDb v10.2, latest	Azure, GCP, AWS	Get started
snowflake		Preview in v1.1.55 (latest)	Azure	Get started
redshift		Preview in v1.1.55 (latest)	AWS	Get started
synapse	development	Preview build ETA mar 27 2021	Azure

NOTE: Supported cloud platforms are based on limited testing and community feedbacks where users indicated the platform they were attempting to run against. yuniql primarily uses Amazon RDS as cloud provider for non-vendor specific platforms.

Distributions	Build Status	Description
Docker image linux-x64		docker pull yuniql/yuniql:linux-x64-latest
Docker imiage win-x64		docker pull yuniql/yuniql:win-x64-latest

Run migrations for PostgreSql, MySql and others

docker run -d -e POSTGRES_USER=sa -e [email protected]! -e POSTGRES_DB=yuniqldb -p 5432:5432 postgres
SETX YUNIQL_CONNECTION_STRING "Host=localhost;Port=5432;Username=sa;Password=[email protected]!;Database=yuniqldb"
SETX YUNIQL_WORKSPACE "c:\temp\yuniql-cli\samples\basic-postgresql-sample"

git clone https://github.com/rdagumampan/yuniql.git c:\temp\yuniql-cli
cd c:\temp\yuniql-cli\samples\basic-postgresql-sample

yuniql run -a --platform postgresql
yuniql list --platform postgresql

Working with Azure DevOps Pipelines Tasks

Run your database migration from Azure DevOps Pipelines. The tasks downloads package and cache it for later execution just like how Use .NET Core or Use Node tasks works. Find Yuniql on Azure DevOps MarketPlace. Developer guide is available here https://yuniql.io/docs/migrate-via-azure-devops-pipelines.

Working with Docker Container

Run your database migration thru a Docker container. This is specially helpful on Linux environments and CI/CD pipelines running on Linux Agents as it facilitates your migration without having to worry any local installations or runtime dependencies. Developer guide is available here https://yuniql.io/docs/migrate-via-docker-container.

git clone https://github.com/rdagumampan/yuniql.git c:\temp\yuniql-docker
cd c:\temp\yuniql-docker\samples\basic-sqlserver-sample

docker build -t sqlserver-example .
docker run sqlserver-example -c "<your-connection-string>" -a --platform sqlserver

Working with ASP.NET Core

Run your database migration when your ASP.NET Core host service starts up. This ensures that database is always at latest compatible state before operating the service. Applies to Worker and WebApp projects. Developer guide is available here https://yuniql.io/docs/migrate-via-aspnetcore-application.

dotnet add package Yuniql.AspNetCore

using Yuniql.AspNetCore;
...
...

//1. deploy new sql server on docker or use existing instance
//$ docker run -dit --name yuniql-sqlserver  -e "ACCEPT_EULA=Y" -e "[email protected]!" -p 1400:1433 -d mcr.microsoft.com/mssql/server:2017-latest

//2. create custom trace message sinks, this can be your own logger framework
var traceService = new ConsoleTraceService { IsDebugEnabled = true };

//3. run migrations
app.UseYuniql(traceService, new Yuniql.AspNetCore.Configuration
{
	Platform = SUPPORTED_DATABASES.SQLSERVER,
	Workspace = Path.Combine(Environment.CurrentDirectory, "_db"),
	ConnectionString = "Server=localhost,1400;Database=helloyuniql;User Id=SA;[email protected]!",
	IsAutoCreateDatabase = true, IsDebug = true
});

Working with .NET Core Console Application

Run your database migration when Console App starts. Developer guide is available here https://yuniql.io/docs/migrate-via-netcore-console-application.

dotnet add package Yuniql.Core

using Yuniql.Core;
...
...

static void Main(string[] args)
{
	//1. deploy new sql server on docker or use existing instance
	//$ docker run -dit -e "ACCEPT_EULA=Y" -e "[email protected]!" -p 1400:1433 -d mcr.microsoft.com/mssql/server:2017-latest

	//2. create custom trace message sinks, this can be your own logger framework
	var traceService = new ConsoleTraceService { IsDebugEnabled = true };

	//3. configure your migration run
	var configuration = Configuration.Instance;
	configuration.Platform = SUPPORTED_DATABASES.SQLSERVER;
	configuration.Workspace = Path.Combine(Environment.CurrentDirectory, "_db");
	configuration.ConnectionString = "Server=localhost,1400;Database=helloyuniql;User Id=SA;[email protected]!";
	configuration.IsAutoCreateDatabase = true;

	//4. run migrations
	var migrationServiceFactory = new MigrationServiceFactory(traceService);
	var migrationService = migrationServiceFactory.Create();
	migrationService.Run();
