To build container images for a specific version of the Unreal Engine, simply specify the UE4 release that you would like to build using full semver version syntax. For example, to build Unreal Engine 4.20.3, run:
You will be prompted for the Git credentials to be used when cloning the UE4 GitHub repository (this will be the GitHub username and password you normally use when cloning https://github.com/EpicGames/UnrealEngine.) The build process will then start automatically, displaying progress output from each of the
docker build commands that are being run in turn.
By default, all available images will be built. See the List of available container images page for details on customising which images are built.
See the Advanced build options page for details on all of the supported flags for customising build behaviour.
