Why is SSM Agent version 3.2.582.0 not yet available on Amazon Linux 2?

Question

As mentioned in https://docs.aws.amazon.com/systems-manager/latest/userguide/managed-instances-default-host-management.html, SSM Agent version 3.2.582.0 or above have to be used in order to make use of Default Host Management Configuration.  However, the latest version on Amazon Linux 2 is 3.1.1732.0 when I use yum update.  Do we need to build from source code in order to use it at this moment?  Thanks.

Answer

If you install the agent manually with 
```
sudo yum install -y https://s3.amazonaws.com/ec2-downloads-windows/SSMAgent/latest/linux_amd64/amazon-ssm-agent.rpm
```
you'll get the required agent version or higher, and the node will register with Systems Manager.  I was also surprised the latest Amazon LInux 2 AMI had a version that didn't work, and your question pointed me to that, thank you.  Hopefully they will update the AMI soon.
