Hello,
I want to use chattr command inside an unprivileged container. Can anyone help me? im using LXD (with lxdui).
Here is the result from containers:
capsh --print
Current: =ep
Bounding set =cap_chown,cap_dac_override,cap_dac_read_search,cap_fowner,cap_fsetid,cap_kill,cap_setgid,cap_setuid,cap_se
tpcap,cap_linux_immutable,cap_net_bind_service,cap_net_broadcast,cap_net_admin,cap_net_raw,cap_ipc_lock,cap_ipc_owner,ca
p_sys_module,cap_sys_rawio,cap_sys_chroot,cap_sys_ptrace,cap_sys_pacct,cap_sys_admin,cap_sys_boot,cap_sys_nice,cap_sys_r
esource,cap_sys_time,cap_sys_tty_config,cap_mknod,cap_lease,cap_audit_write,cap_audit_control,cap_setfcap,cap_mac_overri
de,cap_mac_admin,cap_syslog,cap_wake_alarm,cap_block_suspend
Ambient set =
Current IAB:
Securebits: 00/0x0/1’b0 (no-new-privs=0)
secure-noroot: no (unlocked)
secure-no-suid-fixup: no (unlocked)
secure-keep-caps: no (unlocked)
secure-no-ambient-raise: no (unlocked)
uid=0(root) euid=0(root)
gid=0(root)
groups=0(root),990(mysyslog)
Guessed mode: UNCERTAIN (0)
I can use chattr in privileged mode. my host os is centos 7 and container os is almalinux 8.9. Is it possible to add cap_linux_immutable capability to the container.
Another question: if i change a container ‘security.privileged: “true” will i loss any data or any problem will occurs ?
Thanks in advance.
