This is an obvious need. 22.04 is the current LTS release of Ubuntu.

Is there any instructions on how to build a custom base image that will work with Image Builder?

We need to move to Ubuntu 22.04 sooner than later to reap performance benefits over Ubuntu 20.04 without having to go to unsupported third-party repos. For example, Python 3.10 is tracked by 22.04 and offers 50-60% speedups over Python 3.8 which is the latest tracked by Ubuntu 20. We are considering working around this issue by adding the deadsnakes repo but the deadsnakes team themselves advise against it in a production setting because they have no mission to keep up with security updates. Our other alternative would be to build newer versions ourselves and maintain them solo, which is understandably quite messy.

Looks like Ubuntu 22 images are now available:

        {
            "arn": "arn:aws:imagebuilder:us-east-1:aws:image/ubuntu-server-22-lts-arm64/x.x.x",
            "name": "Ubuntu Server 22 LTS ARM64",
            "type": "AMI",
            "platform": "Linux",
            "osVersion": "Ubuntu 22",
            "owner": "Amazon",
            "dateCreated": "2023-03-03T03:49:16.708Z"
        },
        {
            "arn": "arn:aws:imagebuilder:us-east-1:aws:image/ubuntu-server-22-lts-x86/x.x.x",
            "name": "Ubuntu Server 22 LTS x86",
            "type": "AMI",
            "platform": "Linux",
            "osVersion": "Ubuntu 22",
            "owner": "Amazon",
            "dateCreated": "2023-03-03T03:49:16.062Z"
        },

I noticed Ubuntu 22.04 is still not a pulldown option in the Parallelcluster 3.5 GUI. Not sure if that's expected or not.

Hi @gns-build-server, yes this is expected, having Ubuntu 22 support on ImageBuilder is a required condition to enable it in ParallelCluster but it's not enough, we need to adapt ParallelCluster cookbook recipes and CLI code to fully enable it. Please continue to follow aws/aws-parallelcluster#4060 Thanks

This issue should be closed as Ubuntu 22.04 is shown as supported in the docs as well: https://docs.aws.amazon.com/imagebuilder/latest/userguide/what-is-image-builder.html#image-builder-os
