Container for Amazon EC2?

Container for Amazon EC2?

[Jun OKAJIMA]

Somebody know any Amazon EC2 Image which
supports any container technology?
Vserver/LXC/OpenVZ... Any technology is Okay,
I want to use pre-created image for EC2.

I found many images for Ubuntu 9.10,
but it lacks some support for LXC.
Fedora12 supports all functions of LXC,
but did not find any image.

It's been a little while (probably a year) since I played with
EC2, but generally the problem is that you don't have much of
a choice for underlying kernels.  So you can't pick vserver/openvz
kernels, and the available kernels are too old to have containers
features.  As kernels get updated, whether you can use lxc or not
will only depend on whether CONFIG_{containers} features are compiled
in.

It couldn't hurt to write the amazon folks and ask about it...

So I tried running one of the public ubuntu karmic images in
ec2 (ami-bb709dd2).  I could sudo apt-get install lxc.  The
default kernel (aki-5f15f636) didn't support namespaces.  Now
you can specify kernels at boot, but I'm not sure if there is
an easy way to find kernels with specific CONFIG_ options.
I'll let you know if I find one with all namespaces and
veth+bridge+macvlan enabled, bc that would then give you
everything you'd need.

This is my result.
I dont know very well about lxc,
but this is usable?

I'm not sure which you mean as usable:  lxc is very usable, and
lets you run multiple application and system containers of various
distros.  The lxc-users-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org mailing list was
recently started to accomodate its growing user base.

The kernel on the ec2 instance, however, is not :)

It might be worth jumping onto #ubuntu-virt and asking whether
they have, or can publish, a kernel with, at the least:

CONFIG_CGROUP_DEVICE=y
CONFIG_CGROUP_FREEZER=y
CONFIG_NAMESPACES=y
CONFIG_UTS_NS=y
CONFIG_IPC_NS=y
CONFIG_USER_NS=y
CONFIG_PID_NS=y
CONFIG_NET_NS=y
CONFIG_VETH=y
CONFIG_MACVLAN=y
CONFIG_BRIDGE=y
CONFIG_DEVPTS_MULTIPLE_INSTANCES=y

Those should be sufficient to start using lxc very nicely

Oh I assume in your zone you have different ami's?  But the latest
lucid testing ami has a good kernel!  In US east zone my ami was
ami-071ff36e

Re: Container for Amazon EC2?

[Jun OKAJIMA]

My zone is this.
Zone: us-east-1d
I think this is US East, Virginia iDC.
