Description of problem:
restart centos container
SELinux is preventing dmesg from 'syslog_read' accesses on the system labeled kernel_t.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that dmesg should be allowed syslog_read access on system labeled kernel_t by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'dmesg' --raw | audit2allow -M my-dmesg
# semodule -X 300 -i my-dmesg.pp
