sqlserver got Mapped port can only be obtained after the container is started error

[qomosoloto]

The container is :

override def container: MSSQLServerContainer = new MSSQLServerContainer(
    dockerImageName = DockerImageName.parse("mcr.microsoft.com/mssql/server:2022-latest")
  )

And in the afterStart() hook:

    super.afterStart()
    logger.info(s"driver name: ${container.driverClassName};;;;started: ${container.container.isHealthy}")
    Class.forName(container.driverClassName)
    val properties = new Properties();
    properties.setProperty("user", container.username);
    properties.setProperty("password", container.password)
    Thread.sleep(10000)
    val connection = DriverManager.getConnection(container.jdbcUrl, properties)

    val statement = connection.createStatement()
    val resultSet = statement.executeQuery(
      "select ROUTINE_DEFINITION,ROUTINE_NAME,ROUTINE_SCHEMA,SPECIFIC_SCHEMA from INFORMATION_SCHEMA.ROUTINES where ROUTINE_TYPE='PROCEDURE'"
    )
    while (resultSet.next()) {
      val ROUTINE_DEFINITION = resultSet.getString("ROUTINE_DEFINITION")
      val ROUTINE_NAME = resultSet.getString("ROUTINE_NAME")
      val ROUTINE_SCHEMA = resultSet.getString("ROUTINE_SCHEMA")
      val SPECIFIC_SCHEMA = resultSet.getString("SPECIFIC_SCHEMA")
      logger.info(
        s"ROUTINE_DEFINITION: $ROUTINE_DEFINITION, ROUTINE_NAME: $ROUTINE_NAME, ROUTINE_SCHEMA: $ROUTINE_SCHEMA, SPECIFIC_SCHEMA: $SPECIFIC_SCHEMA"
      )
    }

    // use Flyway to execute repeatable sql
    val flyway = new Flyway(
      new FluentConfiguration()
        .dataSource(container.jdbcUrl, container.username, container.password)
        .locations("db/sqlserver")
    )
    flyway.migrate()

But I got error below:

Anyone knows why and how to resolve it ?
PS: under linux environment, openjdk 11 and scalatest.

Same here, but with Munit and Kafka container.

Solved the issue by running:
container.start()
