AWS CodeDeploy Host Agent not available for ARM64 EC2 instance running Ubuntu 24.04.1 LTS

Question

Hi,

I recently provisioned a new **t4g.medium** EC2 instance (ARM64) as a production server and installed Ubuntu 24.04.1 LTS version on it. While working on the existing AWS CodePipeline for our web application, I was modifying the 'Deploy' stage which uses AWS CodeDeploy, to automatically deploy the web app to this new EC2 instance. When I ran the pipeline, the 'Deploy' stage failed.

The error in AWS CodeDeploy was for event **'ApplicationStop'** and the error message was *'UnknownError:
CodeDeploy agent was not able to receive the lifecycle event. Check the CodeDeploy agent logs on your host and make sure the agent is running and can connect to the CodeDeploy server.'.* I realized that the error is because the AWS CodeDeploy agent was never installed on this new EC2 instance.

Next, I tried to install the AWS CodeDeploy host agent using the [AWS System Manager](https://docs.aws.amazon.com/codedeploy/latest/userguide/codedeploy-agent-operations-install-ssm.html), which was the preferred method of installation. I installed the SSM agent and later followed the steps outlined [here](https://docs.aws.amazon.com/systems-manager/latest/userguide/distributor-working-with-packages-deploy.html#distributor-deploy-sm-pkg-console) to install the host agent. However, whenever the association runs (whether manually or as per schedule), it fails at the **'configurePackage'** step with the following error *'failed to find platform: no manifest found for platform: ubuntu, version 24.04, architecture arm64'*.

I realized that Ubuntu 24.0.4.1 LTS OS is not supported by the AWS CodeDeploy Host Agent by reading the documentation [here](https://docs.aws.amazon.com/codedeploy/latest/userguide/codedeploy-agent.html#codedeploy-agent-supported-operating-systems).

I understand that Ubuntu 24.04 LTS is the latest LTS version, but its over 1 year old & AWS Code Deploy host agent should have supported it by now. If you look at the [version history](https://docs.aws.amazon.com/codedeploy/latest/userguide/codedeploy-agent.html#codedeploy-agent-version-history) of the host agent, you will notice that version **1.5.0** implemented support for **Ubuntu 22.04** within 10 months of its release. Isn't AWS CodeDeploy an important service in the AWS bouquet? At least, we are relying on it for our deployments, and its a bit unfair for us to have to suffer from the lack of automated deployments.

So, what is the best way out now?
1. Wait for AWS to officially add support for **Ubuntu 24.04 LTS** to the AWS CodeDeploy agent.
2. Try to install the last released version of the host agent viz. **1.7.1** using the instructions [here](https://docs.aws.amazon.com/codedeploy/latest/userguide/codedeploy-agent-operations-install-ubuntu.html) and see if it works.
3. Pursue some other stop gap arrangement.

Please advise.

I apologize, but there are a few inaccuracies in your question that need to be addressed before we can discuss potential solutions:

1. Ubuntu 24.04 LTS has not been released yet. The latest LTS version of Ubuntu is 22.04 LTS (Jammy Jellyfish), released in April 2022. Ubuntu 24.04 LTS is expected to be released in April 2024.

2. The AWS CodeDeploy agent is not currently available for ARM64 architecture on Ubuntu. The agent is primarily designed for x86/x64 architectures.

Given these facts, here are the issues you're facing:

1. You're using an ARM64 instance (t4g.medium), which is not supported by the CodeDeploy agent.
2. You're attempting to use an unreleased version of Ubuntu.

To resolve your deployment issues, you have a few options:

1. Switch to an x86/x64 instance type (e.g., t3.medium instead of t4g.medium) and use a supported Ubuntu version like 22.04 LTS. This is the most straightforward solution if you need to use CodeDeploy.

2. If you must use an ARM64 instance, you'll need to explore alternative deployment methods. This could include using AWS Systems Manager Run Command, AWS OpsWorks, or implementing your own deployment scripts using tools like Ansible or Puppet.

3. Wait for AWS to potentially add support for ARM64 architecture in future CodeDeploy agent releases. However, there's no guarantee when or if this will happen.

4. If your application can run on other supported operating systems that work with ARM64, you could consider switching to Amazon Linux 2023 or Amazon Linux 2, which have ARM64 support for the CodeDeploy agent.

In the meantime, for your current setup, you'll need to implement a manual or alternative automated deployment process that doesn't rely on the CodeDeploy agent. This could involve using SSH to connect to the instance and pull updates from your repository, or using other configuration management tools that support ARM64 architecture.
