# Distro Specifics
|
||||
|
||||
Arch dependencies: `arch-install-scripts` `dnsmasq`
|
||||
|
||||
# Basic Setup
|
||||
|
||||
Make and start a linux container called 'playtime':
|
||||
|
||||
> # lxc-create -n playtime -t download
|
||||
|
||||
> # lxc-ls --fancy
|
||||
|
||||
> # lxc-start playtime
|
||||
|
||||
Attach it:
|
||||
|
||||
> # lxc-attach playtime
|
||||
|
||||
# Networking
|
||||
|
||||
Place the following in /etc/default/lxc-net to configure the network:
|
||||
|
||||
---
|
||||
|
||||
# Leave USE_LXC_BRIDGE as "true" if you want to use lx
|
||||
cbr0 for your
|
||||
# containers. Set to "false" if you'll use virbr0 or
|
||||
another existing
|
||||
# bridge, or mavlan to your host's NIC.
|
||||
USE_LXC_BRIDGE="true"
|
||||
|
||||
# If you change the LXC_BRIDGE to something other than
|
||||
lxcbr0, then
|
||||
# you will also need to update your /etc/lxc/default.c
|
||||
onf as well as the
|
||||
# configuration (/var/lib/lxc/<container>/config) for
|
||||
any containers
|
||||
# already created using the default config to reflect
|
||||
the new bridge
|
||||
# name.
|
||||
# If you have the dnsmasq daemon installed, you'll als
|
||||
o have to update
|
||||
# /etc/dnsmasq.d/lxc and restart the system wide dnsma
|
||||
sq daemon.
|
||||
LXC_BRIDGE="lxcbr0"
|
||||
LXC_ADDR="10.0.3.1"
|
||||
LXC_NETMASK="255.255.255.0"
|
||||
LXC_NETWORK="10.0.3.0/24"
|
||||
LXC_DHCP_RANGE="10.0.3.2,10.0.3.254"
|
||||
LXC_DHCP_MAX="253"
|
||||
# Uncomment the next line if you'd like to use a conf-
|
||||
file for the lxcbr0
|
||||
# dnsmasq. For instance, you can use 'dhcp-host=mail1
|
||||
,10.0.3.100' to have
|
||||
# container 'mail1' always get ip address 10.0.3.100.
|
||||
#LXC_DHCP_CONFILE=/etc/lxc/dnsmasq.conf
|
||||
|
||||
# Uncomment the next line if you want lxcbr0's dnsmasq
|
||||
to resolve the .lxc
|
||||
# domain. You can then add "server=/lxc/10.0.3.1' (or
|
||||
your actual $LXC_ADDR)
|
||||
# to your system dnsmasq configuration file (normally
|
||||
/etc/dnsmasq.conf,
|
||||
# or /etc/NetworkManager/dnsmasq.d/lxc.conf on systems
|
||||
that use NetworkManager).
|
||||
# Once these changes are made, restart the lxc-net and
|
||||
network-manager services.
|
||||
# 'container1.lxc' will then resolve on your host.
|
||||
#LXC_DOMAIN="lxc"
|
||||

|
||||
|
||||
Then start the lxc NAT:
|
||||
|
||||
> sudo systemctl restart lxc-net
|
||||
|
||||
> sudo systemctl restart NetworkManager
|
||||
|
||||
... and make sure the bridge's ip-range doesn't intefere withe local network.
|
||||
|
||||
> sudo arp-scan -I lxcbr0 -l
|
||||
|
||||
The lxc template is in /etc/lxc/default.conf. You need to modify it so that it uses lxcbr0.
|
||||

|
||||
|
||||
/etc/lxc/default.conf
|
||||
lxc.net.0.type = veth
|
||||
lxc.net.0.link = lxcbr0
|
||||
lxc.net.0.flags = up
|
||||
lxc.net.0.hwaddr = 00:16:3e:xx:xx:xx

# Making machines
|
||||
|
||||
> sudo lxc-create -n roach -t download -- --dist archlinux --release current --arch amd64
|
||||
|
||||
Arch linux containers take up about 600 Megs.
|
||||
|
||||
To speed up the startup process, one can install haveged and start the haveged.service. Haveged stops the wait-time for system entropy creation.
|
||||
|
||||
Machines are stored in /var/lib/lxc.
|

# Starting

> lxc-attach -n roach
