How to use localstack as S3 in Magento 2 in development env?

Question

I am trying to mock S3 on my local machine, for which I have used localstack. I am using localstack via docker image, which is running successfully on my local machine.

I have followed below URL to setup localstack in my system:

https://onexlab-io.medium.com/localstack-s3-e28ad393c09

I can create S3 bucket and upload and list files from my local machine after setup.

But how to use localstack in Magento 2 in development env. After setting up Magento and localstack whenever I am trying to enable remote storage via below command:

bin/magento setup:config:set --remote-storage-driver aws-s3 --remote-storage-bucket m242_bucket --remote-storage-region us-east-1

it is returning with below error message:

Adapter error: Unable to write file at location: storage.flag. In ConfigSetCommand.php line 151:
            Parameter validation failed

I think this error is due to endpoint URL of S3. We need to set localstack's S3 endpoint here in order to enable remote storage. But I am unable to get any help on google regarding this.

Please someone help me in this.

Add this to the end of your env.php file just before the closing ];. This assumes

,
'remote_storage' => [
        'driver' => 'aws-s3',
        'config' => [
            'bucket' => 'm242_bucket',
            'bucket_endpoint' => false,
            'region' => 'east-1',
            'scheme' => 'http',
            'endpoint' => 'http://localstack:4566',
            'use_path_style_endpoint' => true,
            'credentials' => [
                'key' => 'C****************C',
                'secret' => 'R****************2',
            ],
            'debug' => true,
