如何以编程方式创建 ami 实例？

Question

lately I am doing some POC's in amazon elastic cloud. I created a sample instance and I uploaded my sample web application and finally saw my hello world jsp.

Now I am trying to create one more instance and want to send data from my first instance to second instance. I know that this can be achieved through zookeeper. But I want to create my second instance programmatically and not through the management console.

How to achieve this? I am thinking that this has something to do with the amazon s3 where we bundle our ami. But not sure about it. Can anyone give me guidelines?

Answer 1

This is a link to the Amazon documentation for creating an AMI. Amazon provide a set of command line tools so you should be able to call these from your script.

you may also find these 3rd party scripts useful for creating a bootable EBS from a running instance.

Or it may be more useful to invoke the AWS EC2 APIs more directly from your application.

You could also use Packer from Hashicorp to automate the creation of amazon AMIs. Check out the link below to find out how to create an AMI using packer :
