Docker run failure - fuse: device not found

Docker Engine General

Hi all,

Using docker on Centos7, arm64.
Have an issue on one of our devices , cannot execute any “docker run” command getting a fuse related error:

[root@localhost docker]# docker run -it --device /dev/ttyMV1 modpoll
docker: Error response from daemon: using mount program fuse-overlayfs: **fuse: device not found,** try 'modprobe fuse' first
fuse-overlayfs: cannot mount: No such file or directory
: exit status 1.
See 'docker run --help'.
[root@localhost docker]#

modprobe fuse didn’t help (no errors on execution)

tried to run with all of the options, any combination:
–privileged --cap-add=SYS_ADMIN --device /dev/fuse

Do not help.same error.

Here is the docker info of 2 units, the working and the non-working one.

Same LINUX kernel on both of the devices.

nothing I have found so far helped out regarding the fuse.
Any suggestion ?
Thanks in advance!

I don’t know how exactly Docker works on Centos 7, but I remember there was something about the storage driver. The current default storage driver is overlay2 every distribution I work with. Your Docker is using fuse-overlayfs and I can’t see the backing filesystem which should be under the storage driver information.

I know sometimes podman on Centos appears to be Docker, but I don’t think Docker info would how what you quoted in that case.

Another thing I noticed is warning at the bottom of the docker info output. This usually appears in case of rootless Docker and searching for the error message I found reports about rootless Docker.

The context usually shows if the Docker is rootless, but the report I mentioned shows the same “default” context.

PS.: Since the question has nothing to do with Docker Hub, I am going to move the topic to another category (I know, many topics not related to Docker Hub in this category)
