AWS FIPS: Create an Image

Learn how to build a custom AMI for use with DKP

This procedure describes how to use the Konvoy Image Builder (KIB) to create a Cluster API compliant Amazon Machine Image (AMI). KIB uses variable overrides to specify base image and container images to use in your new AMI.

The default AWS image is not recommended for use in production. We suggest using Konvoy Image Builder to create a custom AMI to take advantage of enhanced cluster operations. Explore the KIB with AWS topics for more options.

Prerequisites

Before you begin, you must:

Check the DKP Supported Kubernetes Versions.
Check the Supported Infrastructure Operating Systems
Download the KIB bundle for your version of DKP prefixed with konvoy-image-bundle for your OS.
Create a working Docker setup.
Ensure you have met the minimal set of permissions from the AWS Image Builder Book.
A Minimal IAM Permissions for KIB to create an Image for an AWS account using Konvoy Image Builder.

Extract KIB Bundle

Extract the bundle and cd into the extracted konvoy-image-bundle-$VERSION folder. The bundled version of konvoy-image contains an embedded docker image that contains all the requirements for building.

The konvoy-image binary and all supporting folders are also extracted. When run, konvoy-image bind mounts the current working directory (${PWD}) into the container to be used.

Set environment variables for AWS access. The following variables must be set using your credentials including required IAM:
CODE
```
export AWS_ACCESS_KEY_ID
export AWS_SECRET_ACCESS_KEY
export AWS_DEFAULT_REGION
```
If you have an override file to configure specific attributes of your AMI file, add it.

Non-air-gapped Environment Create FIPS-140 images

KIB can produce images containing FIPS-140 compliant binaries. Use the fips.yaml override file provided with the image bundles.

You can also find these override files in the Konvoy Image Builder repo.

A non-air-gapped example of override file use is the command below, which produces a FIPS-compliant image on RHEL 8.4 for AWS:
Replace ami with your infrastructure provisioner

CODE

konvoy-image build --overrides overrides/fips.yaml images/ami/rhel-84.yaml
