Obtaining Container Images:

Available Image Sources

What EULA-compliant sources are available for obtaining Unreal Engine container images?

Prerequisite reading:

This page assumes the reader has read and understood the following pages:


Sources of Unreal Engine runtime images

Runtime images are container base images for running packaged Unreal projects. Packaged Unreal projects can run in any container image that includes the required runtime libraries. These requirements vary based on platform:

Since runtime base images do not contain any Unreal Engine components, they can be distributed without any restrictions and shared publicly on container registries such as Docker Hub. A number of pre-configured base images are readily available for download:

Sources of Unreal Engine development images

Development images are images which contain the “Engine Tools” (Editor and build tools.) As discussed in the Unreal Engine EULA Restrictions page, container images that include the Engine Tools for building and packaging Unreal projects or plugins cannot be distributed publicly. These container images must only be distributed privately to ensure compliance with the terms of the EULA.

Since building development images can be a time-consuming process, it is typically preferable to use pre-built images where available. If pre-built container images that meet your requirements are not available (or you wish to create container images for a custom version of the Unreal Engine) then you will need to build images and distribute them within your organisation via whichever private sharing mechanism is most appropriate.

The following sources provide pre-built development container images:

The following sources are available for building development container images:
