Why doesn't the container_commands, commands, files of config file under .ebextensions work?

Question

Ok, I have been struck on this problem for almost a week.

THis is how my config files look.

01touch.config

container_commands:
  01_mov_file:
    command: "touch /home/createdByContainerCommands.txt"
    cwd: /home/

08movehttpdconf.config

Resources:
  AWSEBAutoScalingGroup:
    Metadata:
      AWS::CloudFormation::Authentication:
        S3Auth:
          type: "s3"
          buckets: ["elasticbeanstalk-us-west-1-11111111111"]
          roleName:
            "Fn::GetOptionSetting":
              Namespace: "aws:autoscaling:launchconfiguration"
              OptionName: "IamInstanceProfile"
              DefaultValue: "aws-elasticbeanstalk-ec2-role"

commands:
  01_gethttpdconf:
    command: aws s3 cp s3://elasticbeanstalk-us-west-1-11111111111/resources/environments/httpd.conf /home/

container_commands:
  01_mov_file:
    command: "cp -f /home/httpd.conf /etc/httpd/conf/httpd.conf"

#files:

The commented out files command was also once tried out.

Both these config files are located in .ebextensions folder and .ebextensions folder is like this

https://i.sstatic.net/AC7VM.png

But the qqd.war would be as follows

myWebApp.zip
  |__ qqd.war
  |__ ROOT.war

where ROOT.war is created using touch command. Hence it is empty file. ROOT.war doesn't contain .ebextensions

None of the config files under .ebextensions of qqd.war seems to be running. 1) Why? 2) Should I include sudo in my commands in .config files?

I read most of the top answers here and tried this as well https://medium.com/trisfera/getting-to-know-and-love-aws-elastic-beanstalk-configuration-files-ebextensions-9a4502a26e3c

No luck. Please help me.

Answer 1

In a multiple .war project, your .ebxtensions folder needs to be at the root as it applies to the machine (EC2 instance), not an individual webapp.

MyApplication.zip
├── .ebextensions
├── foo.war
├── bar.war
└── ROOT.war

This is explained here for further reading:
