Just as a reference, I posted here first but it didn’t attract much interests: https://stackoverflow.com/questions/63725623/device-acl-not-visible-in-docker-container
I have a serial device which I get access through ACL which can be seen on the host OS:
fgervais@fgervais-System-Product-Name:~$ getfacl /dev/ttyUSB3
getfacl: Removing leading '/' from absolute path names
# file: dev/ttyUSB3
# owner: root
# group: dialout
user::rw-
user:fgervais:rw-
group::rw-
mask::rw-
other::---
I then map it in a container:
docker run --rm -it -v $(pwd):/project -w /project --user $(id -u):$(id -g) -v /etc/group:/etc/group -v /etc/passwd:/etc/passwd --device /dev/ttyUSB3:/dev/ttyUSB3 espressif/idf:v3.3.2 bash
However inside the container I don’t have access anymore:
fgervais@caee53c47877:/project$ id
uid=1000(fgervais) gid=1000(fgervais) groups=1000(fgervais)
fgervais@caee53c47877:/project$ getfacl /dev/ttyUSB3
getfacl: Removing leading '/' from absolute path names
# file: dev/ttyUSB3
# owner: root
# group: dialout
user::rw-
group::rw-
other::---
Anyone knows why?
