Using UEC consists of creating and registering images with the Cloud Controller.
This page describes the process for Ubuntu 10.04 LTS.
There is more than one way to obtain a virtual image:
- Download an image from the network, bundle and upload it
- Create a custom image using VMBuilder
- Use the Image store to download and install and image
Here we will describe the process of downloading one of the daily builds that are built and published automatically. The process is similar for Official Released Images
Note: the shell variables that are set in the below code snippets are very useful for scripts or to reuse them when typing commands. |
- Download the UEC image for the architecture you want. You can do it from your browser or from the command line:
TIMESTAMP=$(date +%Y%m%d%H%M%S) RELEASE=lucid ARCH=amd64 # Or this might be i386 [ $ARCH = "amd64" ] && IARCH=x86_64 || IARCH=i386 UEC_IMG=$RELEASE-server-uec-$ARCH URL=http://uec-images.ubuntu.com/$RELEASE/current/ [ ! -e $UEC_IMG.tar.gz ] && wget $URL/$UEC_IMG.tar.gz uec-publish-tarball $UEC_IMG.tar.gz $RELEASE-$TIMESTAMP
- Now, your kernel and image will have been uploaded into Eucalyptus and should be ready to run. To confirm, run the following command:
euca-describe-images EMI=$(euca-describe-images | grep emi- | head -n1 | awk '{print $2}')You should see a registered kernel and image and they should be marked as 'available'.
