Create Your Own Operating System: Build, Deploy, And Test Your Very Own Operating Systems For The In ((INSTALL))

Programming your own operating system is more complicated than most other types of coding. With that in mind, you need a lot of knowledge and experience to take on this challenge. However, you can put yourself on the right track with three basic steps:

Learning OS development is one of the most challenging programming tasks you can undertake. However, succeeding in your effort to program your own operating system will mark you as a competent programmer and one who deeply understands how processors, hardware, and computer programs work together to create what the rest of the world takes for granted as a functioning computer.

Image Builder reduces the amount of work involved in creating and managing images at scale byautomating your build pipelines. You can automate your builds by providing your buildexecution schedule preference. Automation reduces the operational cost of maintainingyour software with the latest operating system patches.

Image Builder provides access to test components that you can use to test your images beforedeployment. You can also create custom test components with AWS Task Orchestrator and Executor (AWSTOE), and usethose. Image Builder distributes your image only if all of the configured tests havesucceeded.

The base image is the selected image and operating system used in your image orcontainer recipe document, along with the components. The base image and thecomponent definitions combined produce the desired configuration for the outputimage.

A component is created from a declarative, plain-text YAML or JSON document thatdescribes the runtime configuration for building and validating, or testing an instancethat is produced by your pipeline. Components run on the instance using a componentmanagement application. The component management application parses the documents andruns the desired steps.

After they are created, one or more components are grouped together using an imagerecipe or container recipe to define the plan for building and testing a virtual machineor container image. You can use public components that are owned and managed by AWS,or you can create your own. For more information about components, see AWS Task Orchestrator and Executor component manager.

There is no cost to use EC2 Image Builder to create custom AMI or container images. However,standard pricing applies for other services that are used in the process. The followinglist includes the usage of some AWS services that can incur costs when you create,build, store, and distribute your custom AMI or container images, depending on yourconfiguration.

Amazon EC2 allows you to set up and configure everything about your instances from your operating system up to your applications. An Amazon Machine Image (AMI) is simply a packaged-up environment that includes all the necessary bits to set up and boot your instance. Your AMIs are your unit of deployment. You might have just one AMI or you might compose your system out of several building block AMIs (e.g., webservers, appservers, and databases). Amazon EC2 provides a number of tools to make creating an AMI easy. Once you create a custom AMI, you will need to bundle it. If you are bundling an image with a root device backed by Amazon EBS, you can simply use the bundle command in the AWS Management Console. If you are bundling an image with a boot partition on the instance store, then you will need to use the AMI Tools to upload it to Amazon S3. Amazon EC2 uses Amazon EBS and Amazon S3 to provide reliable, scalable storage of your AMIs so that we can boot them when you ask us to do so.

The RunInstances call that initiates execution of your application stack will return a set of DNS names, one for each system that is being booted. This name can be used to access the system exactly as you would if it were in your own data center. You own that machine while your operating system stack is executing on it.

You can currently use Windows Server, SUSE Enterprise Linux, Ubuntu, and Amazon Linux AMIs on P2 and G3 instances. P3 instances only support HVM AMIs. If you want to launch AMIs with operating systems not listed here, contact AWS Customer Support with your request or reach out through EC2 Forums.
