Proxmox - перенос контейнеров из LXC и отключение apparmor
Материал из support.qbpro.ru
- Имеем виртуальный хост LXC 3.0.1 на базе Debian Мне надо перенести контейнеры с этого хоста на хост Proxmox.
- Создание архива контейнера исходном хосте:
- останавливаем контейнер:
lxc-stop -n wiki
- На хосте LXC находим папку с контейнером и переходим в нее, в rootfs.
cd /var/lib/lxc/wiki/rootfs
- создаем архив контейнера в папке /home:
tar -czvf /home/wiki.tar.gz ./
- полученный архив переносим на хост Proxmox и выполняем его конвертацию:
pct create 101 wiki.tar.gz -description wiki -hostname wiki -memory 1024 -rootfs volume=vmdata1:32 -storage vmdata1 -password mypassword
- пояснение:
pct create 101 - создание ноды 101 wiki.tar.gz -description wiki - архив wiki.tar.gz с пометкой wiki -hostname wiki - имя контейнера / хоста -rootfs volume=<имя носителя proxmox>:<размер образа диска в Гб> -storage vmdata1 - носитель на Proxmox где будет создан образ с носителем
- Для того чтобы не прописывать массу настроек для вновь созданного контейнера после конвертации в apparmor, правим:
mcedit /var/lib/lxc/101/101.conf .. lxc.apparmor.profile = generated lxc.apparmor.allow_nesting = 1 ..
mcedit /var/lib/lxc/apparmor/lxc-107_\<-var-lib-lxc\>
#include <tunables/global>
