Elastic Beanstalk not executing hooks: "skipping hooks scripts under /opt/elasticbeanstalk/hook-CodePudding

I'm trying to get Elastic Beanstalk (Amazon Linux 2, Node.js 16) to run some pre-deploy hooks. I'm using .ebextensions to create a hook in /opt/elasticbeanstalk/hooks/.

In .ebextensions, I have a file, 04_use_yarn.config:

files:
    "/opt/elasticbeanstalk/hooks/appdeploy/pre/49yarn.sh":
        mode:    "000775"
        owner:   root
        group:   users
        content: |
            #!/bin/bash

            # <Contents of the script I'm trying to run>

When SSHing into the instance, I can see that the 49yarn.sh file in /opt/elasticbeanstalk/hooks/appdeploy/pre/ is generated correctly. But during the deploy, I see that it logs "[WARN] skipping hooks scripts under /opt/elasticbeanstalk/hooks/". I can't find any documentation about what would make it skip the hooks in that directory.

How can I make it not skip my hook?

Here are the relevant logs from eb-engine.log:

CodePudding user response：

As per documentation:

On Amazon Linux 2 platforms, custom platform hooks in the /opt/elasticbeanstalk/hooks/ folder are entirely discontinued. Elastic Beanstalk doesn't read or execute them.

This is why the script(s) are being skipped.

You will need to migrate over to platform hooks.
