title: ms-sql-server says exited on docker?
body: <p>my class requires us to use ms sql server but i have a mac so i found a tutorial using docker and azure data studio. I'm really new to this whole sql thing so go easy on me. But whenever I close docker or just randomly, i checked docker and it says under ms-sql-server exited(127). what does that mean?</p>
  <p>Also how do i backup a database on azure data studio? My teacher said we need to use a connection string at one point that she easily got on windows but i didn't get one when i downloaded sql onto my mac. please help.</p>
