Cloud SIG/EC2 Creation
Creating your own custom images for EC2 is a quick and easy process. While there are many ways to create an EC2 image, this page will walk you through using boxgrinder. Boxgrinder is chosen here because the packages are in fedora, and it is a simple process that anyone can use. The Cloud SIG maintains basic appliance definition files in the cloud-kickstarts git repository on fedorahosted.org
Local creation or EC2 based creation
For boxgrinder to generate images, you will need to have boxgrinder installed somewhere. Simple enough, though you have a couple of options here. Boxgrinder can be installed on your fedora host by running:
'yum install rubygem-boxgrinder-core rubygem-boxgrinder-build'
Or, if you would rather have the image creation and publish happen on AMI hosts, you can run boxgrinder in one of the project supported meta-appliances.
Whichever route you choose, a little bit of configuration is required. First, you will need a config file with a little information about your Amazon AWS account. Put the following BoxGrinder config into a file named:
/root/.boxgrinder/config. Insert appropriate values, see: http://boxgrinder.org/tutorials/boxgrinder-build-plugins/#S3_Delivery_Plugin, for more information.
plugins: s3: access_key: AWS_ACCESS_KEY # (required) secret_access_key: AWS_SECRET_ACCESS_KEY # (required) bucket: stormgrind-test # (required) account_number: 0000-0000-0000 # (required) path: /images # default: / cert_file: /home/a/cert-ABCD.pem # required only for ami type key_file: /home/a/pk-ABCD.pem # required only for ami type ebs: access_key: AWS_ACCESS_KEY # required secret_access_key: AWS_SECRET_ACCESS_KEY # required account_number: AWS_ACCOUNT_NUMBER # required delete_on_termination: false # default: true
Actual image creation requires an appliance definition file to get started. The Cloud SIG maintains basic configuration files for current Fedora releases in cloud-kickstarts git repository on fedorahosted.org. You can grab the configuration file from here, and add packages as necessary for your application. Once you have the configuration file you want, it is as simple as running a single command:
For an S3 backed image:
boxgrinder-build /path/to/your/fedora.appl -p ec2 -d AMI
For an EBS backed image
boxgrinder-build /path/to/your/fedora.appl -p ec2 -d ebs
This will build your image, upload it, and register the AMI, though you will have to make it public yourself. Note that boxgrinder works through plugins, and everything is done in steps. If you want both S3 and EBS based images, run the commands in order, and the EBS image will use the output from the S3 backed to save considerable time. If you require any assistance, people are always willing to help on irc.freenode.net at #fedora-cloud, or on the fedora cloud sig email list.
