FUSE inside Docker

With respect to Nickolay’s answer below, the --privileged flag is not strictly required, for fuse. And you’re best to avoid giving that much privilege to your container.

You should be able to get things working by replacing it with --cap-add SYS_ADMIN like below.

docker run -d --rm \
           --device /dev/fuse \
           --cap-add SYS_ADMIN \
      <image_id/name>

Sometimes this may not work. In this case, you should try and tweak the AppArmor profile or just disable it as follows:

docker run -d --rm \
           --device /dev/fuse \
           --cap-add SYS_ADMIN \
           --security-opt apparmor:unconfined \
      <image_id/name>

Finally, if all fails, use –privileged flag.
