无法使用已安装的弹性文件系统部署 Elastic Beanstalk 应用程序

Question

I am in the process of migrating a Node.js application from the deprecated Amazon Linux 1 platform to an Amazon Linux 2 platform.

Everything works, up until I attempt to mount the EFS following the exact directions provided by Amazon . If I do not include this script (modified with the appropriate values), the Node app deploys (using eb deploy ) and all parts that are not dependent on the EFS work as expected.

Once I include the script, I receive the following error and the deployment fails -

[ERROR] An error occurred during execution of command [app-deploy] - [PreBuildEbExtension]. Stop running the command. Error: EbExtension build failed. Please refer to /var/log/cfn-init.log for more details. 

When running on the Linux 1 platform, I experienced no issues with this EFS script and variables. I have tried using a larger EC2 instance, and that has not worked (t2.small instead of a t2.micro).

Answer 1

The issue turned out to be incorrectly set security groups.
