fails building ue4-minimal, not enough space on disk

Output of the ue4-docker info command: PS C:\Users\moray> ue4-docker info ue4-docker version: 0.0.72 (latest available version is 0.0.72) Operating system: Windows Server 2019 Datacenter Version 1809 (OS Build 17763.1579) Docker daemon version: 19.03.13 NVIDIA Docker supported: No Maximum image size: 999GB Available disk space: 1.39 TiB Total system memory: 16 GiB physical, 18.37 GiB virtual Number of processors: 2 physical, 4 logical

The build command I am using is “ue4-docker build 4.26.0”, I am building on a server 2019 datacenter VM.

I am able to build engine and source images, but it fails building minimal.

The failure point for the first run was step 21/27, and it failed copying the build over, with an error about there not being enough space on the disk. I assume this is the disk in a docker container, the host system has a couple of TB of storage available.

The output from ue4-docker attached is from the second run of the build command, engine and source images are already built.

I have been experiencing a similar failure point when trying to build 4.24.3. Is there something I have missed?

This appears to be the direct result of this conan-ue4cli issue, so I’ll need to fix conan-ue4cli before the ue4-full image can be built for Unreal Engine 4.26.0.

This was fixed in 4.26.1 in case anyone is searching for this (@mloftis’ PR merged). 😃
