## LXC
|
||||
LXC == LinuX Container
|
||||
|
||||
Mit den selben Kernel-Mechanismen ("cgroups", "IP namespaces") wie z.B. Docker wird ein - in z.B. ein Verzeichnis installiertes - Linux-System gestartet und dabei vom Hauptsystem getrennt.
|
||||
|
||||
Auf jeder VM sind ~25 LXC(ontainer) mit verschiedenen Distributionen installiert. Die Distribution sollte sich aus den Namen der Container ableiten lassen.
|
||||
|
||||
### Anzeigen der Container
|
||||
```
|
||||
root@tn00-purple:~# lxc-ls -f
|
||||
NAME STATE AUTOSTART GROUPS IPV4 IPV6 UNPRIVILEGED…
|
||||
tn00-alma8 RUNNING 1 ansible 192.168.1.138 - false
|
||||
tn00-alpine3b RUNNING 1 ansible 192.168.1.194 - false
|
||||
tn00-alpine3c RUNNING 1 ansible 192.168.1.139 - false
|
||||
tn00-alpine3d RUNNING 1 ansible 192.168.1.152 - false
|
||||
tn00-alpine3e RUNNING 1 ansible 192.168.1.134 - false
|
||||
tn00-arch RUNNING 1 ansible 192.168.1.192 - false
|
||||
[...]
|
||||
```
|
||||
|
||||
### Container in /etc/hosts hinzufügen
|
||||
Bitte nur einmal ;) ausführen!
|
||||
```
|
||||
sudo lxc-ls -f -F ipv4,name | grep -v NAME | sudo tee -a /etc/hosts
|
||||
```
|
||||
|
||||
### Wechseln in den Container
|
||||
```
|
||||
root@tn00-purple:~# lxc-attach tn00-alpine3b
|
||||
~# cat /etc/os-release
|
||||
NAME="Alpine Linux"
|
||||
ID=alpine
|
||||
VERSION_ID=3.11.0
|
||||
PRETTY_NAME="Alpine Linux v3.11"
|
||||
HOME_URL="https://alpinelinux.org/"
|
||||
BUG_REPORT_URL="https://bugs.alpinelinux.org/"
|
||||
~# ^D
|
||||
```
|
||||
Beenden mit Strg-D (Shell beenden)
|
||||
|
||||
### Zugriff auf Dateien im Container
|
||||
Die Container sind auf File-Basis unter `/var/lib/lxc/CONTAINERNAME/` installiert, das File-System liegt dort jeweils im Verzeichnis `rootfs`.
|
||||
|
||||
Ein `cat /var/lib/lxc/tn00-alpine3b/rootfs/etc/os-release` im Host würde also die gleiche Dateien anzeigen wie oben.
