No news really

I just want to tell Beco there is no news.

This place is not deserted

emilkrueper — Thu, 31 Mar 2011 11:24:21 +0000

Please come back someday soon. Right now I am very busy with some exciting developments at work and being with my family. So there is not much time for this place. Well, but I am still here. Take care!

From father to sons

Today I had the genuine opportunity to watch my sons at their first concert:

The boys

Finally another car

Well, today I finally bought another car and put an end to driving this Kangoo which was okay for some time but not what I consider to be a proper car. So now it’s an Audi Quattro Avant. Yeah. I feel like having a car again.

I was years ago already having an Audi Quatto and liked it very much. So after I decided it’s the time for a change I had the urgent need to have again a Quattro. Today I feel blissful, already drove 400km with the car.

Fun

Oh noes, we missed uptime anniversary

emilkrueper — Wed, 08 Sep 2010 21:38:16 +0000

Fsck, today I recognized we missed to celebrate something – we have several servers with two years+ of interruption-free uptime now. Sorry. May you continue to crunch numbers until the end of days! Yours sincerely!

Relocation from dedicated server to vserver accomplished

emilkrueper — Wed, 14 Jul 2010 11:17:53 +0000

Last evening I started relocation of all services from my old dedicated server to a vserver at another location. So I have to say bye bye old fellow, I am not going to miss you so much. But thanks anyways for (usually) being so reliable.

These days I can have better performance for less money. And I can spent the money in ~~things like pizza, beer and so on~~ in our family money socks. Yeah!

Something different – Amazon EC2 CentOS AMI

emilkrueper — Wed, 07 Jul 2010 14:58:08 +0000

I have successfully built some CentOS 5.5 AMI with EBS and with instance storage. First I had to create an openvz CentOS instance and then I started building the AMI in the openvz environment. Cool.

Amazon EC2 Gentoo AMIs and the Cloud

emilkrueper — Wed, 26 May 2010 20:12:34 +0000

Lately I have been very much traveling around and visiting different conferences related to cloud computing. I have been discussing a lot the assets and drawbacks for us at work to put some stuff into the cloud. Well, very soon I had to dig into the AWS. I had a look at all the available EC2 AMIs and I asked myself why there is no recent gentoo based x86_64 AMI for Amazons EC2. And in truth I needed a proper gentoo EC2 AMI asap to start testing.

So what’s wrong? Is it too much weird command line kung fu to create such an machine image? Or is there no demand for Gentoo x86_64 images? People don’t use Gentoo anymore since the Gentoo hype was over long before there was AWS? Gentoo people are unaware there is 64bit available and still stick to 32bit? AWS people don’t want Gentoo people to use Gentoo images since the Fedora machine images are much better for everyone? Yeah.

I deceided to roll out my own AMI. I did some research and read lots of articles about the different ways to create those machine images. Twenty minutes later I felt enlightened:

1. You can convert an existing xen image or
2. create your AMI with VMware and convert this or
3. you can use an existing AMI and base your AMI on it and so forth.

Sounds like crap. I like building things by my own and have more control on the inside of the result.
It took some time to figure out how to proceed and how to solve small emerging hurdles.

Working on a good build host it takes maybe twenty to thirty minutes from zero to have a basic AMI ready to go. Basically you need to create the AMI file, format it with some filesystem, mount the file as a loop device, extract an stage3 archive, install some requirements and modify some config files. The most time is wasted waiting for ec2-upload-bundle to complete. It’s enough time to get another cup of coffee, sit on the sofa and read some pages in the newspapers.

I think the result is pretty good already. I have completed different automations and have begun working on the details to create almost autonomous clusters, this is again funny stuff with crons, bash, sed, awk and perl.

EC2 is definitly very interesting. If you need some help with gentoo AMIs you can just sent me an email or put a line in the comments.

All the best, Emil
