codedeploy on boto does not allow content overwrite

Question

I'm using boto3==1.20.42. Here is my code:

import boto3

client = boto3.client('codedeploy')

response = client.create_deployment(
    applicationName='MyWebsite',
    deploymentGroupName='MySiteDeploymentGroup',
    revision={
        'revisionType': 'S3',
        's3Location': {
            'bucket': 'my-code-deploy',
            'key': 'drupal-deploy2.zip',
            'bundleType': 'zip',
        },
    },
    description='Deploying updates',
    ignoreApplicationStopFailures=False,
    fileExistsBehavior='OVERWRITE'
)
print(response)

What I expect is that it overwrite the contents as I specified above but I observe that it is not overwriting files as you can see in the used deployment settings image below:

Can anyone help me figure out how to overwrite contents programmatically with boto?

Answer 1

fileExistsBehavior is per deployment setting. You can't set a default value for that. For each new deploymentyou have to explicitly specify that it should be OVERWRITE.

Answer 2

Actually the code above seems to work but if you open the settings of a previous deployment on the AWS console, it does not show the flag as selected which lead to me thinking that it did not overwrite.
