I used the official tutorial to create a default instance https://docs.microsoft.com/en-us/sql/linux/sql-server-linux-setup-ubuntu
but now I want to create a named-instance and can't find how to do that
SQL Server on Linux doesn't support the notion of "multi-instance", so there are no named instances on Linux.
You can see that its Windows only feature here: https://docs.microsoft.com/en-us/sql/sql-server/install/work-with-multiple-versions-and-instances-of-sql-server?view=sql-server-2017
