What you need to know Microsoft's SQL Server on Windows Containers Beta program has been going since 2017. The program is now being suspended indefinitely. Related docker hub repos and the tags within said repos have been hit with deletion as a result. Are you a fan of SQL Server on Linux containers? If so, you're in luck because that Microsoft offering isn't going anywhere. On the flip side, the SQL Server on Windows Containers Beta program is being suspended indefinitely. Not only that, but two docker hub repositories, "microsoft/mssql-server-windows-express" and "microsoft/mssql-server-windows-developer," along with these repositories' tags, have been deleted. Images from the repos won't be available, either.
