How to Fix CodeDeploy Not Copying Code from GitHub Properly: A Complete Guide

When deploying your application using AWS CodeDeploy, encountering deployment issues can be frustrating, especially when CodeDeploy fails to copy your code from GitHub as expected. One common scenario involves having specified the correct Commit ID in your deployment process, yet facing errors that indicate files are missing or scripts are failing to execute properly. In this guide, we'll explore the solution to the problem of CodeDeploy not copying code from GitHub, breaking down each step for clarity.

Understanding the Problem

In a typical setup, you should be able to pull your application code from a GitHub repository to your deployment server automatically. However, if the system fails to do this, it often leads to errors during the installation phase, as other scripts rely on files that are not present.

Code Structure

Here’s the assumed structure of your GitHub repository:

The appspec.yml Configuration

Your appspec.yml file, which guides the CodeDeploy process, should look something like this:

The hooks section dictates the order in which deployment scripts will run during the deployment lifecycle.

The Error Encountered

While executing the deployment, you may have encountered the following error message:

Upon reviewing the logs, you noticed this crucial output:

This indicates that the pm2.dev.json file is missing from the /home/ubuntu/my-service directory, likely because the files were not copied before the script attempted to reference them.

The Solution

The solution to this problem involves updating your deployment configuration, specifically altering the BeforeInstall phase.

Updating the Hook

Change the Hook: Modify the appspec.yml file by changing the hook from BeforeInstall to Install. This change ensures that your deployment script will run after the files have been copied to the destination directory, ensuring the needed files are available for the script.

Why This Works

Execution Order: By using the Install hook, you ensure that the content designated in the files section of your appspec.yml is copied to the specified destination before your deployment script executes.

Availability of Files: This adjustment removes the dependency conflict that arises when the deployment script tries to access files that have not yet been transferred to the server.

Conclusion

When facing issues with CodeDeploy not copying your code from GitHub, ensuring the correct lifecycle hooks are in place is crucial. Changing the deployment hook from BeforeInstall to Install resolves the common problem where scripts fail to find necessary files during execution. By following this guide, you should be able to execute successful deployments, allowing your application to run smoothly on deployment servers.

If you still encounter problems even after making these changes, consider checking your repository settings or permissions on your deployment server to ensure everything is set up correctly.
