xorio42/rencfs repository overview

Get the image

docker pull xorio42/rencfs

Start a container to set up mount in it

docker run -v ~/Downloads:/share -it --device /dev/fuse --cap-add SYS_ADMIN --security-opt apparmor:unconfined xorio42/rencfs:latest /bin/sh

Replace ~/Downloads with a path on the host machine you want to share with the container.

In the container, create mount and data directories.

mkdir mnt && mkdir data

Start rencfs

rencfs mount --mount-point mnt --data-dir data

Enter a password for encryption. If it says that the password doesn't match, please start it again; it will work the second time. This is an unknown possible bug.

Get the container ID

docker ps

In another terminal, attach the running container with the above ID

docker exec -it <ID> /bin/sh

From here, you can play with it by creating files in mnt directory.

cd mnt
mkdir 1
ls
echo "test" > 1/test
cat 1/test

cp /share/some-file
ls -la

When you close the mount point by Crtl+C in the first window, it will try to unmount the mount point. If it's in use, it could not succeed. In that case, you can manually unmount it as root

cd && umount mnt

If that still fails, you can try

umount -f mnt

If still failing

umount -l mnt
