FUSE implementation for overlayfs

fuse-overlayfs

An implementation of overlay+shiftfs in FUSE for rootless containers.

Limitations:

Read-only mode is not supported, so it is always required to specify an upperdir and a workingdir.

Usage:

$ fuse-overlayfs -o lowerdir=lowerdir/a:lowerdir/b,upperdir=up,workdir=workdir merged

Specify a different UID/GID mapping:

$ fuse-overlayfs -o uidmapping=0:10:100:100:10000:2000,gidmapping=0:10:100:100:10000:2000,lowerdir=lowerdir/a:lowerdir/b,upperdir=up,workdir=workdir merged

Build Requirements:

fuse-overlayfs requires libfuse > v3.2.1

On Fedora: dnf install fuse3-devel

Static Build:

buildah bud -t fuse-overlayfs -f ./Dockerfile.static .
