functions.sh generate_appimage fails to work in a CentOS 7 Docker container: failed to open /dev/fuse

Hi,

I downloaded the functions.sh script from this repo, ran it (with . /functions.sh) and ran generate_appimage and it gave the error message:

fuse: failed to open /dev/fuse: Operation not permitted
Could not mount AppImage
Please see https://github.com/probonopd/AppImageKit/wiki/FUSE

I have fuse and squashfs installed, specifically I have run:

yum install -y git gcc gcc-c++ xz libtool make bzip2 perl wget sudo squashfs-tools fuse fuse-libs fuseiso lzma \
               yum-utils gtk-doc epel-release libffi-devel

If relevant my AppDir is /AppDir.

Thanks for your time,
Brenton

Travis CI is even giving me errors because of this https://travis-ci.org/fusion809/AppImages/builds/177757649.

Try adding the following arguments to docker run:
--cap-add SYS_ADMIN --cap-add MKNOD --device=/dev/fuse
If you're running Ubuntu container, you may need this one as well:
--security-opt apparmor:unconfined
