Before setting ACL permissions, we recommend you read Managing S3 Access Control Lists (ACLs).
The put_object_acl() method sets the permissions on an object using access control lists (ACL).
Syntax Notes
To grant permission to a user, specify the grantee with the following parameters:
For users on external providers only (for example, Active Directory or LDAP) pass:
The EmailAddress parameter and provide the user's principal name in the format user@domain, where user is the user name and domain is configured for an external auth provider on the cluster (LDAP, NIS).
The Type parameter and provide AmazonCustomerByEmail as its value.
For any users (including users on the local provider), pass:
The ID parameter and provide the user's VID as its value.
Tip
A VID is a VAST ID used in the cluster's internal user database. A user VID is retrievable by running the
user queryVAST CLI command and specifying udb as the context of the query. The output includes the user's VID.The Type parameter and provide CanonicalUser as its value.
To grant permission to a predefined group, specify Group as the 'Type' and pass the group's URI as the 'URI':
For the All Users group: 'http://acs.amazonaws.com/groups/global/AllUsers'
For the Authenticated Users group: 'http://acs.amazonaws.com/groups/global/AuthenticatedUsers'
Examples
In this example, a user with VID 3 is granted full control permission to the object my_object in the bucket my_bucket owned by JDoe whose VID is 2.
response = client.put_object_acl(
AccessControlPolicy={
'Grants': [
{
'Grantee': {
'ID': '3',
'Type': 'CanonicalUser',
},
'Permission': 'FULL_CONTROL'
},
],
'Owner': {
'DisplayName': 'JDoe',
'ID': '2'
}
},
Bucket='my_bucket',
Key='my_object',
)
In this example, the predefined AUTHENTICATED_USERS group is granted WRITE permission to the object my_object in the bucket my_bucket owned by JDoe whose VID is 2..
response = client.put_object_acl(
AccessControlPolicy={
'Grants': [
{
'Grantee': {
'Type': 'Group',
'URI': 'http://acs.amazonaws.com/groups/global/AuthenticatedUsers'
},
'Permission': 'WRITE'
},
],
'Owner': {
'DisplayName': 'JDoe',
'ID': '2'
}
},
Bucket='my_bucket',
Key='my_object',
)
