How to add "Overwrite the content" in codedeploy via cloudformation template

Question

I template is fine and running but when i'm trying to deploy new version it's giving me different errors.

Such as below

The deployment failed because a specified file already exists at this location. I did deleted the whole folder.
Script at specified location: scripts/app_stop.sh run as user root failed with exit code 1

LifecycleEvent - ApplicationStop Script - scripts/app_stop.sh [stderr]Unknown operation 'httpd'.

I have the httpd up and running.

Edit- I have specified "IgnoreApplicationStopFailures: true" already in my DeploymentGroup Resources section.

Edit- My app_stop.sh looks like below -

if [ -d /var/www/html/scripts ]; then
    sudo rm -Rf /var/www/html/* /opt/codedeploy-agent/deployment-root/*
fi
isExistApp=`pgrep httpd`
if [[ -n  $isExistApp ]]; then
    sudo systemctl stop httpd         
fi

Edit - Added the template to be changed.

Group:
    Type: AWS::CodeDeploy::DeploymentGroup
    Properties:
      ApplicationName: !ImportValue DeployName
      Deployment:
        IgnoreApplicationStopFailures: true
        Description: 'Code Deploy to Train'  
        Revision:
          RevisionType: S3
          S3Location:
            Bucket: '<sample>'
            BundleType: 'zip'
            Key: '<test>.zip'   
      Ec2TagFilters:
        -
          Key: 'Type'
          Value: 'Train'
          Type: 'KEY_AND_VALUE'
      ServiceRoleArn: !GetAtt [PipeRole, Arn]

I would be needing the to use the below options with the Overwrite feature alongside this template.

Can you be more specific? Can you show your template and explain what's wrong with it or how you want to change it? — Marcin, Aug 26 '21 at 03:16
Hello @Marcin, I have added the requested details to the question, apologies for not adding it earlier. — Shourya Sharma, Aug 26 '21 at 03:47
Sorry, but its still not clear. What do you mean by " Overwrite feature" or ""Overwrite the content""? Which content? Overwrite how? — Marcin, Aug 26 '21 at 03:59
Okay i suppose this issue is addresses in below question. https://stackoverflow.com/questions/54587693/codedeploy-configuration-to-overwrite-files And it is resolved, I need to add according to the below link to overwrite the files present already in the folder. https://docs.aws.amazon.com/codedeploy/latest/userguide/reference-appspec-file-structure-files.html Thanks a lot for your help @Marcin — Shourya Sharma, Aug 26 '21 at 04:05

For quick reference here's the solution mentioned in the comments above.

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/site
    file_exists_behavior: OVERWRITE
