Native Overlay Diff for Overlay2 on Rootless Docker
No matter what I do, I can't quite get it to work, and the internet is full of reports where this is the case. I'm on Ubuntu 20.04 with a 5.4.0-58 kernel. systemctl --user status docker reports:
dockerd-rootless.sh[1932]: [...] level=warning msg=" Not using native diff for overlay2, this may cause degraded performance for building images: failed to set opaque flag on middle layer: operation not permitted" I tried:
Setting options overlay metacopy=off redirect_dir=off for the overlay kernel module
Installing packages like fuse-overlayfs and its libraries
Reports:
Failed to pull images in rootless mode with overlayfs: "createDirWithOverlayOpaque(...) ... input/output error" docker/for-linux#1055 https://stackoverflow.com/questions/65273160/how-to-enable-native-overlay-diff-on-debian-docker-rootless ubuntu:18.04 container commit fails with error processing tar file: operation not permitted containers/buildah#2326
Steps to reproduce the issue:
Install rootless Docker on Ubuntu 20.04.1
