## Installation d'un container
|
|
|
|
~~~
|
|
# lxc-create -t download -n test
|
|
~~~
|
|
|
|
Avant de démarrer la VM mettre ces lignes dans le fichier de conf du conteneur : ``/var/lib/lxc/test/config`
|
|
|
|
~~~
|
|
lxc.network.type = veth
|
|
lxc.network.link = br1
|
|
lxc.network.ipv4 = 10.1.0.X/24
|
|
lxc.network.ipv4.gateway = 10.1.0.254
|
|
lxc.network.name = eth0
|
|
lxc.network.flags = up
|
|
~~~
|
|
|
|
(Il est conseillé de supprimer systemd du container car ce dernier est mal géré pour le moment)
|
|
|
|
~~~
|
|
# apt install sysvinit-core
|
|
~~~
|
|
|
|
## Utilisation
|
|
|
|
Démarrer un conteneur :
|
|
|
|
~~~
|
|
# lxc-start -n test -d
|
|
~~~
|
|
|
|
Entrer dans un conteneur :
|
|
|
|
~~~
|
|
# lxc-attach -n test
|
|
~~~
|
|
|
|
Arreter un conteneur :
|
|
|
|
~~~
|
|
# lxc-stop -n test
|
|
~~~
|
|
|
|
Autres commandes utiles :
|
|
|
|
~~~
|
|
# lxc-info -n test-container
|
|
# lxc-console -n test-container
