I’m trying to do the following within a Docker container:
docker run -it <image> bash root$ dd if=/dev/zero of=file.fs bs=1024 count=1024 root$ mkfs.ext4 file.fs root$ mkdir tmp root$ mount -t ext4 file.fs tmp mount: tmp/: mount failed: Unknown error -1 root$ dmesg dmesg: read kernel buffer failed: Operation not permitted
The same commands above (with sudo) work fine on my host.
How can I get mount to succeed within the Docker container?
I’m trying to automate building some root filesystems for an embedded Linux target from a Docker container so I need to be able to mount from within.
Thanks in advance!
