Hi everybody,
is there a way to use Debian-Wheezy containers in a clean,
working way on lxc?
My current setup involves a Debian-Wheezy Host with several Wheezy containers.
As stated on the Debian wiki (wiki.debian.org/LXC), the original template ships
with several problems (mainly missing ttys for console login and other stuff).
We set up our containers with the template recommended on this mailinglist.
Installation worked pretty fine, but there are some problems according to the
init scripts:
1. Stopping/Restarting containers via /etc/init.d/lxc fails with a timeout:
####
[....] Stopping Linux Containers: test.xxx.com
telinit: timeout opening/writing control channel /run/initctl
####
2. Shutdown/Reboot inside a container stops all processes except of init, so the
container finally does not shutdown or reboot.
We can see the still active init process for the container via lxc-ps
####
CONTAINER PID TTY TIME CMD
test.xxx.com 4352 ? 00:00:05 init
####
The only way to finally stop a container is via lxc-stop
Did anyone experience a similiar problem, or is there an existing workaround for
this?
Regards,
Danijel

Dear Ajith,
if you need to tailor your Linux down for an embedded environment, you may take a look on Gentoo Linux. Here you may choose freely between different software alternatives. And in case of the init framework, in the moment SystemD is an option and the default is openRC.

hi All,
I've seen a couple of times in the past like this:
# lxc-ls --fancy --stopped --fancy-format name,state
NAME STATE
--------------------
finance STOPPED
hammer STOPPED
ijc-cipool STOPPED
jay STOPPED
marvin4jsci STOPPED
marvinci STOPPED
svntest STOPPED
In fact VMs are running fine, but I updated lxc (from daily ppa) this morning.
Is this some kind of bug? Do others meet this issue?

Out of curiosity, did you see it in the past before you you updated from
the PPA today?

Ohh, I'm afraid, I misunderstood the question.
Yes, I did as well, a couple of time.
As for that a couple of time I experienced really stopped guests after package update.

Hi,
I've been happily using ubuntu's stock lxc (originally
in 12.04, now in 13.04), and finally have an occasion
to run a server inside a container. I'd like it to
be visible from the outside.
There are plenty of web pages about this, but they seem to
assume that you've created the lxc config file by hand.
I have never done that; I just use whatever lxc-create creates.
What's the simplest way to get a container to look
like just another host on the LAN, starting with
sudo apt-get install lxc
sudo lxc-create -t ubuntu -n foobar
on ubuntu 13.04?
Thanks,
Dan

Hi Dan,
I've just started working with LXC so this how I am doing it and maybe some one else can fill in any areas I've left out.
If you are going to have a local LAN and outside WAN connection than you will need two ethernet cards ( 1 for each network )
Unless you already have a router setup that can punch a hole into your local network's firewall creating a DMZ connection for that container.
What I have been doing is creating a bridge on the host with a static ip.
Then each container is configured to it's own static ip address inside the container's /etc/network/interface config doc
If you check out this mailing list's archive for the last week or so you will find an example of most of my config files I used in this test.
The problem I was having is the gateway on a container was not loading .
So I ending up writing a simple Ubuntu startup script to manually load the gateway settings at the container's OS boot time.
For now it does the job until I can figure out why.
Bellow are the document paths to most config files you will need to deal with.
There are plenty of good blog post out on the web that will give you deeper details.
Finally you may want to check out this project to see it might make all the above easier for your needs. http://lxc-webpanel.github.io
I looked at it but ended up doing all manual configurations, as I wanted to better understand LXC structure for now.
Good luck.
-Kevin
Host ( create bridge )
/etc/network/interfaces
/etc/sysctl.conf
net.ipv4.ip_forward = 1
/etc/lxc/lxc.conf
/etc/default/lxc
/var/lib/lxc/containers_name/config
/var/lib/lxc/conatianers_name/rootfs/etc/network/interfaces

Get your SQL database under version control now!
Version control is standard for application code, but databases havent
caught up. So what steps can you take to put your SQL databases under
version control? Why should you start doing it? Read more to find out.
