Host parameter for AWS S3 Storage Options is not being respected

[voiddragon]

I've set the host parameter here but the request URL is still being directed to https://bucket-name.s3.amazonaws.com

DBBACKUP_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'
DBBACKUP_STORAGE_OPTIONS = {
    'access_key': "",
    'secret_key': "",
    'bucket_name': "bucket-name",
    'host': "s3-eu-west-1.amazonaws.com",
    'location': 'database-backups/'
}

Hello @voiddragon
As DBBackup uses storage backends, your issue seems directly related to storages.backends.s3boto3.S3Boto3Storage

Isn't it ?

[voiddragon]

@ZuluPro The documentation states that the host setting in the storage options can be used to change the default boto3 hostname, do I have to override the boto3 settings instead for this to work?

[ZuluPro]

@voiddragon The documentation primarly states that the storage is a third package and you should read its doc to understand it.

[voiddragon]

@ZuluPro Yes I managed to get it to work by modifying the settings for storages, I think the documentation should be updated to reflect that the host setting does not actually work and that it should be updated on the storages settings level to avoid future confusion.

I've had this very same issue and fixed it before finding what other people wrote about it on github. I give a +1 for having this issue fixed by the developers.

I spent quite some time to figure out the solution. The only problem with the documentation, currently, is that the 'host' option doesn't exist anymore with django-storages. Instead, we now need to use the 'endpoint_url', e.g.

DBBACKUP_STORAGE_OPTIONS = {
    'endpoint_url': 'https://s3-compatible-service.example.com',
    'access_key': '*************',
    'secret_key': '*************',
    'bucket_name': 'my-backup',
    'default_acl': 'private',  # WARNING: this option will soon be removed
}

You can look up the available options from get_default_settings() in storages/backends/s3boto3.py.

NOTE: The ''default_acl' option will be removed with the next release of django-storages according to their CHANGELOG.
