This GitHub repository aims to provide a centralized location for community engagement. In here you will find documentation, Dockerfiles and additional developer resources.

**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.
- [Linux-based containers](https://github.com/Microsoft/mssql-docker/tree/master/linux): This Docker image uses [SQL Server 2025 Developer Edition on Linux](https://docs.microsoft.com/en-us/sql/linux/) on top of an Ubuntu 24.04 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 2025 Express Edition and SQL Server 2025 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).

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.

## Troubleshooting & Frequently Asked Questions

- "Unknown blob" error code: You are probably trying to run the Windows Containers-based Docker image on a Linux-based Docker Engine. If you want to continue running the Windows Container-based image, we recommend reading the following community article: [Run Linux and Windows Containers on Windows 10](https://stefanscherer.github.io/run-linux-and-windows-containers-on-windows-10/).
- "Unknown blob" error code: This error usually indicates that you are attempting to run a Windows container image on a Linux container runtime. Verify that your image and container runtime use the same OS. If you need to run the Windows-based image, switch Docker to Windows Containers mode.

- When using the Windows Docker CLI you must use double quotes instead of single ticks for the environment variables, else the mssql-server-linux image won't find the `ACCEPT_EULA` or `SA_PASSWORD` variables which are required to start the container.

- The 'sa' password has a minimum complexity requirement (8 characters, uppercase, lowercase, alphanumerical and/or non-alphanumerical)

- Licensing for SQL Server in Docker: Regardless of where you run it - VM, Docker, physical, cloud, on prem - the licensing model is the same and it depends on which edition of SQL Server you are using. The Express and Developer Editions are free. Standard and Enterprise have a cost. More information here: [https://www.microsoft.com/en-us/sql-server/sql-server-2016-editions](https://www.microsoft.com/en-us/sql-server/sql-server-2016-editions)
