const port = process.env.PORT || 8080

app.get('/', (req, res) => {
  res.json({
    message: 'Hello World'
  })
})

app.listen(port, () => console.log(`Example app listening on port ${port}!`))

start docker container

run as SA

view password (!)

change password:

download
mssql datastudio

create and save data in volume

to see volumes

backup external to local desktop...

copy into container

backup from within the mssql in new backup folder

exit
copy it to desired location...

code first approach:
dotnet ef migrations add InitialMigration
dotnet ef database update

sql operations studio:
no longer in active development...

azure datastudio:
same as sql operations studio...

in azure datastudio:
new query
