I'm trying to run clearlinux docker container on CentOS7. It launches successfully but basic fs operations fail:
$ docker run -it clearlinux:latest /bin/bash -c "ls -ld /"
ls: cannot access '/': Operation not permitted
However on CentOS8 and Ubuntu there is no such issue. It works fine:
$ docker run -it clearlinux:latest /bin/bash -c "ls -ld /"
drwxr-xr-x 1 root root 4096 Apr 14 14:18 /
I'm installing docker this way: https://docs.docker.com/engine/install/centos/
I've tried three different kernels: 5.6.4, 4.4.219, 3.10.0
Also I've tried both ext4 and xfs as Backing filesystem for overlay2.
Probably there is an issue with el7 kernel or el7 docker-ce package. Any help would be much appreciated.
