### Why I did it HLD implementation: Container Hardening (https://github.com/sonic-net/SONiC/pull/1364) ### How I did it Reduce linux capabilities in privileged flag #### How to verify it Check container's settings: Privileged is false and container only has default Linux caps, does not have extended caps. ``` admin@vlab-01:~$ docker inspect nat | grep Privi "Privileged": false, admin@vlab-01:~$ docker exec -it nat bash root@vlab-01:/# capsh --print Current: cap_chown,cap_dac_override,cap_fowner,cap_fsetid,cap_kill,cap_setgid,cap_setuid,cap_setpcap,cap_net_bind_service,cap_net_raw,cap_sys_chroot,cap_mknod,cap_audit_write,cap_setfcap=ep ```
