Couldanyone help me investigate an issue with EC2 instance profile? I have create an EC2 instance and I put an IAM role.But, when I check on the instance I see: No roles attached to instance profile: xxx-instance-profile.

After attaching the AmazonSSMManagedInstanceCore policy to an existing EC2 role, I had to reboot the EC2 instance before it showed up in Systems Manager. Thanks to @Jason who mentioned this in a comment.


I am not sure what you mean by an issue with EC2 instance profile. Instance profiles are permission sets that you grant to an EC2 instance, by defining a policy that contains the permissions required and attaching that policy to a role. The role is attached to an EC2 instance. Because the role will be used by a service it must have a trust relationship to that service.


In this case, your instance has a route to the AWS Public Service for Systems Manager Session Manager. The instance must have the Systems Manager Session Manager agent installed. This agent is pre-installed on Amazon Linux 2, Amazon Linux and Ubuntu 16.04, 18.04, 20.04.


Assuming the agent is installed and there is a route to the service, then your instance as you mentioned need rights via IAM to access the service. This is done by granting a role to the EC2 instance.


If you instance is not visible, it could be that you do not have a route to the AWS Service Endpoints. For example the EC2 instance is not in a public subnet or does not have a route to the internet. In this case you need to add 3 VPC endpoints to your subnet. These endpoints are:


In this scenario even though the vm is in a private subnet it has outbound internet access via a public nat gateway which in turn has outbound access via the internet gateway. The nat gateway picutred here has a public ip. When a nat gw with a public ip sits infront of a private subnet those vms use that pubic ip for internet outbound, so ssm works.


Well I wonder what's going to happen here? If you guessed absolutely nothing, you'd be right. There's no public ip no route out of any kind and no way in. It's a completely isolated tenant. So how do you get ssm working this scenario? Next diagram.


In this instance, you need to add vpc endpoints - unsurprisingly to the vpc - and then associate them with the private subnet you want to connect into. Endpoints are created at vpc level and then "associated". The ssm endpoints are of type "interface" so an eni is created in that subnet for each endpoint and a private dns zone is set up so that the vm sends traffic to the local ssm enis and not to the aws fabric globally.


Answering "Systems Manager -> Session Manager, I don't see my instances" --Do you see your managed instances in Fleet Manager? One reason why Instances are not visible to the Systems manager is if the instance has no ssm agent installed. Eg: Ubuntu comes with ssm pre-installed but RHEL does not have ssm pre-installed. Check this out : -center/systems-manager-ec2-instance-not-appear/


Systems manager immediately showed my ubuntu instances, for RHEL instances I had to manually install ssm agent. -manager/latest/userguide/agent-install-rhel.htmlThis might be the reason why you cant see instances in session manager as well.


I had the same issue with all of my EC2 instances not showing up in Session Manager, even though they had the correct security/networking set up, turns out I had to go to Systems Manager -> Session Manager -> Preferences and Enable KMS encryption.


In my case, it took about 30 minutes for EC2 instance to appear in Fleet Manager. I had existing EC2 without any attached IAM service role. I created a new IAM role with AmazonSSMManagedInstanceCore and AmazonEC2RoleforSSM permission policies and in about 30 minutes my EC2 popped up in Fleet Manager. BTW, Windows platform EC2 instance also comes with preinstalled SSM Agent.


The following is an alphabetical list of the 47 service system managers (Consolidated Municipal Service Managers (CMSMs) and District Social Services Administration Boards (DSSABs)) and the municipalities they serve. Service system managers are designated under the Child Care and Early Years Act, to manage child care services and early years programs and services across the province.

AWS Systems Manager collects operational data from numerous AWS services and automates activities across your AWS resources. You can divide resources into logical groups like applications, application layers, or production vs development environments.


You can save information in the form of parameter values, including license codes, database strings, Amazon Machine Image (AMI) IDs, and passwords. Values can alternatively be stored as plain text or encrypted data.


Session Manager is an AWS Systems Manager feature that is completely managed. Session Manager allows you to manage your edge devices, Amazon Elastic Compute Cloud (Amazon EC2) instances, and on-premises servers and virtual machines (VMs).


This was everything about the AWS system manager and the major points. Now that you understand what AWS SSM is, why you should use it, and how to utilize it, I hope this helps you get started on your AWS SSM path. Start using it right away and share your thoughts in the comments area below.
