 **SQL Server in Docker** comes in two different flavors:
 - [Linux-based containers](https://github.com/Microsoft/mssql-docker/tree/master/linux): This Docker image uses [SQL Server 2017 Developer Edition on Linux](https://docs.microsoft.com/en-us/sql/linux/) on top of an Ubuntu 16.04 base image. This is meant to be run on [Docker Engine](https://www.docker.com/products/overview) on its multiple platforms.  There are also Dockerfiles here for building [RHEL](linux/preview/RHEL/Dockerfile) & [CentOS](linux/preview/CentOS/Dockerfile) based images.
-- [Windows-based containers](https://github.com/Microsoft/mssql-docker/tree/master/windows): These Docker images use SQL Server 2017 Express Edition and SQL Server 2017 Developer Edition. Both images are based on Windows Container technology and can only be run using [Docker Engine for Windows Containers](https://msdn.microsoft.com/en-us/virtualization/windowscontainers/docker/configure_docker_daemon).

You can currently sign-up for SQL Server 2019 on Windows Containers available in our [Early Adopter Preview](https://cloudblogs.microsoft.com/sqlserver/2019/07/01/sql-server-2019-on-windows-containers-now-in-early-adopters-program/) program.

+Before choosing to run a SQL Server container for production use cases, please review our [support policy](https://support.microsoft.com/en-us/help/4047326/support-policy-for-microsoft-sql-server) for SQL Server Containers to ensure that you are running on a supported configuration.
 
 **SQL Server Command Line Tools(sqlcmd,bcp)** are also available as a Docker Image. You can now deliver SQL Server management payload using this as a base image for your CI/CD scenarios. Check out the [mssql-tools Docker Image](https://hub.docker.com/r/microsoft/mssql-tools/) to get started.
