Amazon Elastic Compute Cloud (EC2) Image Builder is a service that allows you to automate the creation of Amazon Machine Images (AMIs). AMIs are pre-configured virtual machine images that contain the operating system, application, and other software required to launch an instance. By using EC2 Image Builder, you can quickly and easily create custom AMIs that are optimized for your specific use case.
In this post, we will walk you through the process of creating AMIs with EC2 Image Builder from start to finish. We will cover the following topics:
- Setting up EC2 Image Builder
- Creating a pipeline for building AMIs
- Customizing AMIs with scripts and packages
- Testing and publishing your AMIs
By the end of this post, you should have a solid understanding of how to use EC2 Image Builder to create custom AMIs for your own projects.
Setting up EC2 Image Builder
Before you can start using EC2 Image Builder to create AMIs, you need to set up the service in your AWS account. Here’s how to do it:
- Go to the EC2 Image Builder page in the AWS Management Console.
- Click the “Create image pipeline” button.
- In the “Create image pipeline” page, give your pipeline a name and a description.
- Select the base image that you want to use as the starting point for your AMI. You can choose from a variety of popular operating systems, such as Amazon Linux, Ubuntu, and Windows.
- Choose a region for your pipeline. This is where the AMI will be stored and made available for use.
- Click the “Create pipeline” button to create your pipeline.
Creating a pipeline for building AMIs
Once you have set up Image Builder, you can start creating AMIs by building a pipeline. A pipeline is a series of steps that are executed in sequence to create an AMI. Here’s how to create a pipeline:
- Go to the EC2 Image Builder page in the AWS Management Console.
- Click the “Create image recipe” button.
- In the “Create image recipe” page, give your recipe a name and a description.
- Select the pipeline that you want to use for building the AMI.
- Choose a source for your recipe. This can be a local file or a URL to a file stored in an Amazon S3 bucket.
- Add any additional steps that you want to include in your recipe. These can include installing packages, running scripts, and customizing the operating system.
- Click the “Create recipe” button to create your recipe.
Customizing AMIs with scripts and packages
One of the benefits of using Image Builder is the ability to customize your AMIs with scripts and packages. This allows you to add specific software and configurations to your AMIs, making them more tailored to your needs.
To customize an AMI with scripts and packages, you can add the following types of steps to your recipe:
- Install packages: This step installs one or more packages from a package manager, such as apt or yum.
- Run scripts: This step runs a script that you specify. You can use this step to perform a wide range of tasks, such as installing software, modifying configuration files, and more.
- Execute commands: This step runs a command that you specify. This can be used to perform tasks such as creating users, setting permissions, and more.
Testing and publishing your AMIs
After you have created and customized your AMI with Image Builder, it’s important to test the AMI to make sure it works as expected. To test an AMI, you can use the “Create image” action in the Image Builder console. This will create a new instance based on your AMI, allowing you to test it in a live environment.
Once you have tested your AMI and are satisfied with the results, you can publish it to make it available for use. To publish an AMI, you can use the “Publish image” action in the Image Builder console. This will make the AMI available in the specified region, and it can be used to launch instances just like any other AMI.
