Birchb1024: /* Container creation */

== LXC ==

[https://en.wikipedia.org/wiki/LXC LXC] is an operating-system-level virtualization method for running multiple isolated Linux systems (containers) on a control host using a single Linux kernel.

With LXC you can run Alpine Linux on container and start services in it using native Alpine Linux' init system (openrc).

This is instruction on how to install Alpine Linux on LXC container.

== Preparation ==

=== LXC installation ===
You have to install "lxc" package on your host system. For example, in Arch Linux you can install it by running:
{{Cmd|sudo pacman -S lxc}}

=== Bridge creation ===
You also have to create network bridge on your host.

[https://wiki.archlinux.org/index.php/Network_bridge Setting up bridge in Arch Linux or Arch Linux based systems]

[https://help.ubuntu.com/community/NetworkConnectionBridge Setting up bridge in Ubuntu or Ubuntu based systems]

Here is example, how to setup bridge with netctl:

Copy sample file "bridge"
{{Cmd|sudo cp /etc/netctl/examples/bridge /etc/netctl/myBridge}}

Modify your bridge configuration file as needed (network interfaces: eno1 and tap0 are, of cource, according to your needs)
{{Cmd|sudo vim /etc/netctl/myBridge}}
<pre>
Description="Bridge connection"
Interface=br0
Connection=bridge
BindsToInterfaces=(eno1 tap0)
IP=dhcp
</pre>

Stop active connection
{{Cmd|sudo systemctl stop dhcpcd}}

Start your bridge
{{Cmd|sudo netctl start myBridge}}

Perhaps you may wish to setup your system to start your bridge automatically at boot time.

== Container creation ==

To install Alpine Linux edge version run:
{{Cmd|sudo lxc-create --name alpine-edge -t alpine -- --release edge}}

You can also configure shared directory which will be accessible from both host and container. In this example we make host's /media/d directory available in container
{{Cmd|sudo mkdir /var/lib/lxc/alpine-edge/rootfs/media/d}}

Modify container's configuration file:
{{Cmd|sudo nano /var/lib/lxc/alpine-edge/config}}

Add folowing lines:
<pre>
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.mount.entry=/media/d media/d none bind 0 0
</pre>

Booting container:
{{cmd|sudo lxc-start -n alpine-edge}}

Shutting down container:
{{cmd|sudo lxc-stop -n alpine-edge}}

Going to Alpine Linux console:
{{cmd|sudo lxc-attach -n alpine-edge}}

== Container setup ==

Modify your apk/repositories configuration file
{{cmd|vi /etc/apk/repositories}}

It is recommended to include "main", "testing" and "community" repositories.
<pre>
http://nl.alpinelinux.org/alpine/edge/main
http://nl.alpinelinux.org/alpine/edge/testing
http://nl.alpinelinux.org/alpine/edge/community
</pre>

Upgrading your Alpine Linux system:
{{cmd|apk update && apk upgrade}}

Starting services:
{{Cmd|/etc/init.d/service_name start}}
or
{{Cmd|rc-service service_name start}}

Adding services to autostart
{{Cmd|rc-update add service_name}}

Restarting your container:
{{Cmd|reboot}}
