Support for Oracle Object Storage

[anhilash]

Hi All,

Is there any support for Oracle Object Storage, We have client who is insisting to host on oracle.

OCI Object Storage is full compatible with AWS S3 API.

You can check this https://medium.com/oracledevs/use-aws-python-sdk-to-upload-files-to-oracle-cloud-infrastructure-object-storage-b623e5681412
And this https://testdriven.io/blog/storing-django-static-and-media-files-on-amazon-s3/

After you apply that tutorials, the following snippet could be useful: pip install boto3 django-storages

# settings.py

ORACLE_BUCKET_NAME = 'myOciBucketName'
ORACLE_BUCKET_NAMESPACE = 'hsrt37fxm24t'
ORACLE_REGION = 'sa-saopaulo-1'

AWS_ACCESS_KEY_ID = os.environ.get('ORACLE_ACCESS_KEY')
AWS_SECRET_ACCESS_KEY = os.environ.get('ORACLE_CUSTOMER_SECRET_KEY')
AWS_STORAGE_BUCKET_NAME = ORACLE_BUCKET_NAME
AWS_S3_CUSTOM_DOMAIN = f"{ORACLE_BUCKET_NAMESPACE}.compat.objectstorage.{ORACLE_REGION}.oraclecloud.com"
AWS_S3_ENDPOINT_URL = f"https://{AWS_S3_CUSTOM_DOMAIN}"
AWS_S3_OBJECT_PARAMETERS = {
    'CacheControl': 'max-age=86400',
}

DEFAULT_FILE_STORAGE = 'core.storage_backends.PublicMediaStorage'
MEDIA_URL = f"https://{AWS_S3_CUSTOM_DOMAIN}/{ORACLE_BUCKET_NAME}/media"

STATICFILES_STORAGE = 'core.storage_backends.StaticStorage'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'upload/static'),
]
STATIC_URL = f"https://{AWS_S3_CUSTOM_DOMAIN}/{ORACLE_BUCKET_NAME}/static"

This is a example of custom backend

from datetime import datetime, timedelta
from urllib.parse import urlencode

from django.conf import settings
from django.utils.encoding import filepath_to_uri

from storages.backends.s3boto3 import S3Boto3Storage


class OracleStorage(S3Boto3Storage):

    def url(self, name, parameters=None, expire=None, http_method=None):
        # Preserve the trailing slash after normalizing the path.
        name = self._normalize_name(self._clean_name(name))
        params = parameters.copy() if parameters else {}
        if expire is None:
            expire = self.querystring_expire

        if not self.custom_domain:
            raise Exception('Must set AWS_S3_CUSTOM_DOMAIN')

        if not settings.ORACLE_BUCKET_NAME:
            raise Exception('Must set ORACLE_BUCKET_NAME')

        url = '{}//{}/{}/{}{}'.format(
            self.url_protocol,
            self.custom_domain,
            settings.ORACLE_BUCKET_NAME,
            filepath_to_uri(name),
            '?{}'.format(urlencode(params)) if params else '',
        )

        if self.querystring_auth and self.cloudfront_signer:
            expiration = datetime.utcnow() + timedelta(seconds=expire)
            return self.cloudfront_signer.generate_presigned_url(url, date_less_than=expiration)

        return url


class StaticStorage(OracleStorage):
    location = 'static'
    default_acl = 'public-read'


class PublicMediaStorage(OracleStorage):
    location = 'media'
    default_acl = 'public-read'
    file_overwrite = False

It is S3 compat and docs exists for it now!
