I wanted to confirm, are the images offered in https://github.com/orgs/EpicGames/packages/container/package/unreal-engine built using the scripts in https://github.com/EpicGames/UnrealEngine/tree/release/Engine/Extras/Containers/Dockerfiles/linux and the instructions on Building the Linux Container Images from Source | Unreal Engine 4.27 Documentation | Epic Developer Community without modification? I’m encountering issues where I get to the build DDC stage and it fails to connect to the zen server. I’m attempting to build 5.5.4.
