The default Epic docker image doesn’t include any downloads. When the tools are bundled in the image they can’t be updated separately from the main docker image, that’s why empty images are good idea since you can use the DeployTool buildgraph node and/or horde cli tools to upload them. If you want horde container with pre-bundled tools, you’ll have to build it yourself.
It’s pretty easy, just run the RunUAT.bat BuildGraph -Script="Engine/Source/Programs/Horde/BuildHorde.xml" -Target="Build Bundled Docker Image" -p4 (remove -p4 if you’re not using perforce and if you don’t have RunUAT.bat in engine root directory you’ll have to use Engine/Build/BatchFiles/RunUAT.bat
