+## Example project with Java and Microsoft SQL Server
+
+{: #example-mssql-project }
+
+The following example runs a maven build in the primary container and spins up a Microsoft SQL Server in a secondary container.
+It waits for the database to start up with the `nc` shell command and then runs `sqlcmd` to create a test database.
+Finally it runs the maven build and tests against the database `circle_test` on `localhost:1433`
+The test user is `sa` to keep it simple (the database is temporary just to run the tests, so security is not really an issue).
