Hi @skime​ 

On Docker, the default location for FME to use as temp is /tmp which should just write files inside the container which in turn uses the local machines storage. You could try setting the FME_TEMP env var for the engine containers to change where the temp files are written.

For Kubernetes, we don't have that exposed by default so you're right, you'd need to add FME_TEMP into the engine-deployments.yaml and add the volume mounts.

You'd just need to make sure that volume is created before you try to start FME Server.
