Hi Simon,
The error "An error occurred (access denied) when calling the ListBuckets operation: Access Denied" would occur if your user does not have permission to view all the S3 buckets in your account. "ListBuckets" is the name of the API call that is made to list all S3 buckets. The corresponding permission to request this API is "s3:ListAllMyBuckets". Therefore, if your user requires access to view all buckets in your account, or they are accessing the S3 console, you will have to add the "s3:ListAllMyBuckets" to the IAM user's policy.
While framing a policy, it is also important to note that some actions support resource-level permissions and some do not. For example, "s3:ListAllMyBuckets" does not support resource-level permissions and you must specify all resources ("*") for this permission. On the other hand, "s3:ListBucket" which is the permission required to list the contents in your bucket, requires you to specify a bucket as the resource. Permissions like "s3:PutObject" and "s3:GetObject" are object-level permissions, and therefore, you must specify an object as the resource. To get a better understanding of which S3 action supports which resource, you can refer to the following link (It also acts as a handy guide while framing policies):
//docs.aws.amazon.com/service-authorization/latest/reference/list_amazons3.html
So in this case, the correct policy would look as follows:
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "ObjectPermissions",
"Effect": "Allow",
"Action": [
"s3:PutObject",
"s3:GetObject",
"s3:DeleteObjectVersion",
"s3:PutObjectVersionAcl",
"s3:DeleteObject",
"s3:PutObjectAcl"
],
"Resource": "arn:aws:s3:::Bucketname/"
},
{
"Sid": "ListBucketContents",
"Effect": "Allow",
"Action": "s3:ListBucket",
"Resource": "arn:aws:s3:::Bucketname"
},
{
"Sid": "ListAllBuckets",
"Effect": "Allow",
"Action": "s3:ListAllMyBuckets",
"Resource": ""
}
]
}
With this policy attached, the user will have access to list all S3 buckets in your account but will be able to list the contents of only the specified bucket. The user will also be able to upload, download and delete objects from the specified bucket.
Hope this helps :)
Recibo este error en la terminal cuando trato de enumerar todos los cubos usando boto3: Ocurrió An error occurred (AccessDenied) when calling the ListBuckets operation: Access Denied .
Aquí está el código:
for bucket in s3.buckets.all(): print(bucket.name)Encontré una pregunta de desbordamiento de pila ( ¿Por qué mi terminal devuelve este error s3? ) y debajo está la solución propuesta. No estoy muy familiarizado con AWS, así que necesito un poco de orientación.
¿Dónde puedo encontrar el diccionario dentro como el que se muestra a continuación dentro de la consola de AWS?
{ "Sid": "AllowListingOfAllBuckets", "Effect": "Allow", "Action": [ "s3:ListAllMyBuckets" ], "Resource": [ "arn:aws:s3:::*" ] }An error occurred (AccessDenied) when calling the ListBuckets operation: Access Denied

Im working in python, I've set all my anycodings_api credentials in the prompt : aws configure.
In my python file when i'm try the code to anycodings_api list all my bucket :
import boto3 s3 = boto3.resource('s3') for bucket in s3.buckets.all(): print (bucket.name)I'm getting this error :
Traceback (most recent call last): anycodings_api File "C:\Users\bakpovo\testAmazon.py", line anycodings_api 3, in for bucket in anycodings_api s3.buckets.all(): File anycodings_api "C:\Users\bakpovo\AppData\Local\Programs\Python\Python38\lib\site-packages\boto3\resources\collection.py", anycodings_api line 83, in iter for page in anycodings_api self.pages(): File anycodings_api "C:\Users\bakpovo\AppData\Local\Programs\Python\Python38\lib\site-packages\boto3\resources\collection.py", anycodings_api line 161, in pages pages = anycodings_api [getattr(client, anycodings_api self._py_operation_name)(**params)] anycodings_api File anycodings_api "C:\Users\bakpovo\AppData\Local\Programs\Python\Python38\lib\site-packages\botocore\client.py", anycodings_api line 276, in _api_call return anycodings_api self._make_api_call(operation_name, kwargs) anycodings_api File anycodings_api "C:\Users\bakpovo\AppData\Local\Programs\Python\Python38\lib\site-packages\botocore\client.py", anycodings_api line 586, in _make_api_call raise anycodings_api error_class(parsed_response, anycodings_api operation_name) anycodings_api botocore.exceptions.ClientError: An error anycodings_api occurred (AccessDenied) when calling the anycodings_api ListBuckets operation: Access Denied
