How to install SSHFS inside Alpine container?

I use php:7.3.2-cli-alpine3.9 as my base image. I also need SSHFS installed inside container since PHP library I use relies on it. I know there are many answers with "if you install SSHFS inside container you are doing it wrong" but in my case I need this software installed inside container not on host.

In my Dockerfile I have

RUN apk update && apk add sshfs;

This command is executed without errors:

fetch http://dl-cdn.alpinelinux.org/alpine/v3.9/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.9/community/x86_64/APKINDEX.tar.gz
v3.9.3-21-g265a28802e [http://dl-cdn.alpinelinux.org/alpine/v3.9/main]
v3.9.3-15-g583c0d55e9 [http://dl-cdn.alpinelinux.org/alpine/v3.9/community]

Executing busybox-1.29.3-r10.trigger
Executing glib-2.58.1-r2.trigger
OK: 25 MiB in 44 packages

But when I am trying to mount remote host

'/usr/bin/sshfs' -C -o reconnect -o 'Port=22' -o 'UserKnownHostsFile=/ssh/known_hosts' -o StrictHostKeyChecking=yes -o 'IdentityFile=/ssh/<FILE>' -o PasswordAuthentication=no '<USER>@<HOST>:/' '/fuse/'

I am getting:

fuse: device not found, try 'modprobe fuse' first

When I am running it I am getting:

modprobe: can't change directory to '/lib/modules': No such file or directory

Am I missing any packages? What else needs to be installed?

Thanks.

In order to run SSHFS inside container it requires privileged permissions.

Install SSHFS by adding this line in Dockerfile: RUN apk update && apk add sshfs;

Run container: docker run --privileged=true -it --rm --name alpine-app transfers-image
