@sparrc @chienhanlin Hi, is there any chance you could take a look at this PR?

Hello @dali546, thanks for reaching out to ECS.

As we have not supported this on ECS-optimized AL2023 AMIs, please create a feature request with more details in https://github.com/aws/amazon-ecs-ami/issues or https://github.com/aws/containers-roadmap/issues for us to work on this request. Thanks.

Hi @chienhanlin, I have created the issue below. Thank you

@chienhanlin There is an already existing issue here: aws/containers-roadmap#1300

[dali546]

Hi @chienhanlin is there any update on this? I would very much like this to be baked in as installing it in userdata is flaky. sometimes the package fails to install, or hangs and never actually gets installed.
When used as part of an EC2 Autoscaling Group, it leads to misconfigured machines being provisioned
