Answer 1

This is a very common error so AWS public docs has a section for the same.

• https://docs.aws.amazon.com/codedeploy/latest/userguide/troubleshooting-deployments.html#troubleshooting-same-files-different-app-name

Basically when creating the deployment, you need to select Overwrite the content option so the deployment does not fail (default behaviour). Details here:

• https://docs.aws.amazon.com/codedeploy/latest/userguide/deployments-rollback-and-redeploy.html#deployments-rollback-and-redeploy-content-options

The default behaviour prevents two Deployments from two different CodeDeploy "Applications" writing the same file and possibly causing some sort of conflict.

Answer 2

cd /var/www/your-directory/public/funnel_webhooks/test/

sudo rm -rf clickfunnel.txt

After removing this file please release the change in the code pipeline.

Now you can specify file_exists_behavior in your appspec file. Allowed values are DISALLOW, OVERWRITE, or RETAIN.

version: 0.0
    os: linux
    files:
      - source: /
        destination: /home/ubuntu/yello
    file_exists_behavior: OVERWRITE
