Docker Compose Sql server Creating a database and tables automatically upon startup

I created a asp.net core web api with Sql server. By running docker compose file I need to create a database and tables. My solutions is as follows

Dockerfile

FROM microsoft/dotnet:2.2-aspnetcore-runtime AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/dotnet:2.2-sdk AS build
WORKDIR /src
COPY StarterPackMSSQL.StarterPackMSSQL.csproj StarterPackMSSQL/
RUN dotnet restore StarterPackMSSQL/StarterPackMSSQL.csproj
COPY . .
WORKDIR /src/StarterPackMSSQL
RUN dotnet build StarterPackMSSQL.csproj -c Release -o /app

FROM build AS publish
RUN dotnet publish StarterPackMSSQL.csproj -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "StarterPackMSSQL.dll"]

docker-compose.yml

version: '3.5'

networks : 
  localdev:
    name: localdev

services:
 starterpackmssql:
    image: ${DOCKER_REGISTRY-}mssql
    restart: always
    build:
      context: .
      dockerfile:StarterPackMSSQL/Dockerfile
    ports:
      - "5001:80"
    depends_on:
      - db-server
    networks:
      - localdev

  db-server:
    image: microsoft/mssql-server-linux
    container_name: db-server
    environment:
      - ACCEPT_EULA=Y
      - MSSQL_SA_PASSWORD=password123
      - MSSQL_TCP_PORT=1433

    ports:
      - "1400:1433"
    networks:
      - localdev

SQL Script

CREATE DATABASE [StarterPacksDB]
GO

USE [StarterPacksDB]
GO

/****** Object:  Table [dbo].[Users]    Script Date: 10/18/2019 10:42:39 PM ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[User](
    [id] [int] IDENTITY(1,1) NOT NULL,
    [handle] [varchar](50) NOT NULL,
 CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED 
(
    [id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

I just need to create database and tables automatically upon when running docker-compose up

And it should work on both mac and windows.
