Installation options

There are three supported installation options for OpenREM v1.0:

  • Docker

  • Native install on Linux

  • Native install on Windows

Docker

This is the quickest and easiest way of installing a fully functioning OpenREM instance, complete with database, web server and DICOM server, on any operating system that supports Docker with Linux containers. This includes Windows 10 with Docker Desktop, but currently excludes Windows Server, though this may change with availability of WSL2 for Windows Server 2019.

The Docker installation has mostly been tested with Ubuntu server, but has also been used successfully with Podman on Redhat Enterprise Linux and other distributions.

Existing Windows or Linux installations of OpenREM 0.10 can be upgraded to run in a Docker installation.

It is advisable that the server OpenREM is installed on has access to the internet to get images from Docker and security updates for the operating system. However, if this is not possible the Docker images can be obtained on a computer that does have access to the internet and transferred to the ‘offline’ serer for installation.

Native install on Linux

A native installation on Linux requires Python, a webserver (eg Nginx) a database (ideally PostgreSQL) and a DICOM server (ideally Orthanc) to be installed, with OpenREM and all the other dependencies being installed via Pip.

Existing installations of OpenREM 0.10 can be upgraded, but this release requires a different version of Python to the older releases, and some services that were previously required are no longer needed. Full upgrade instructions are provided, based on an Ubuntu Server installation.

Native install on Windows

A native installation on Windows Server requires Python, a database (ideally PostgreSQL) and a DICOM server (ideally Orthanc) to be installed, with OpenREM and all the other dependencies being installed via Pip. IIS is the recommended webserver to use on Windows.

This installation process can be used with Windows 10 (and probably 11), but this is not advised for production use as Windows 10 and 11 are not designed to be servers.

As for native Linux installs, existing installations of OpenREM 0.10 can be upgraded, but this release requires a different version of Python to the older releases, and some services that were previously required are no longer needed. Full upgrade instructions are provided, based on a Windows Server 2019 installation.
