How to authenticate to Bluemix S3 Lite? - ibm-cloud

I'm trying to use S3 API with Bluemix object storage using the following code:
import boto3, pprint, sys;
s3 = boto3.Session().client(
service_name="s3",
region_name="us-geo",
endpoint_url="https://s3-api.us-geo.objectstorage.softlayer.net",
aws_access_key_id="auto-generated-apikey-<redacted>",
aws_secret_access_key="<redacted>");
pprint.pprint(s3.list_buckets());
but keep getting AccessDenied error:
<Error>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
<Resource></Resource>
<RequestId><redacted></RequestId>
<httpStatusCode>403</httpStatusCode>
</Error>
I took aws_access_key_id and aws_secret_access_key from the "Service Credentials" tab. I used similar code for AWS S3, and it worked. What am I missing?

The IAM-enabled cos uses a slightly different syntax for client creation that is supported by a fork of the boto3 library.
Here’s an example in the docs: https://console.bluemix.net/docs/services/cloud-object-storage/libraries/python.html

Operation failed: "This request is not authorized to perform this operation." in Synapse with a Pyspark Notebook

I try to execute the following command line:
mssparkutils.fs.ls("abfss://mycontainer#myadfs.dfs.core.windows.net/myfolder/")
I get the error:
Py4JJavaError: An error occurred while calling z:mssparkutils.fs.ls.
: java.nio.file.AccessDeniedException: Operation failed: "This request is not authorized to perform this operation.", 403, GET, https://myadfs.dfs.core.windows.net/mycontainer?upn=false&resource=filesystem&maxResults=5000&directory=myfolder&timeout=90&recursive=false, AuthorizationFailure, "This request is not authorized to perform this operation.
I followed the steps described in this link
by granting access to me and my Synapse workspace the role of "Storage Blob Data Contributor" in the container or file system level:
Even that, I still get this persistent error. Am I missing other steps?
I got the same kind of error in my environment. I just followed this official document and done the repro, now it's working fine for me. You can follow the below code it will solve your problem.
Sample code:
from pyspark.sql import SparkSession
account_name = 'your_blob_name'
container_name = 'your_container_name'
relative_path = 'your_folder path'
linked_service_name = 'Your_linked_service_name'
sas_token = mssparkutils.credentials.getConnectionStringOrCreds(linked_service_name)
Access to Blob Storage
path = 'wasbs://%s#%s.blob.core.windows.net/%s' % (container_name,account_name,relative_path)
spark.conf.set('fs.azure.sas.%s.%s.blob.core.windows.net' % (container_name,account_name),sas_token)
print('Remote blob path: ' + path)
Sample output:

Writing log to gcloud Vertex AI Endpoint using gcloud client fails with google.api_core.exceptions.MethodNotImplemented: 501

Trying to use google logging client library for writing logs into gcloud, specifically, i'm interested in writing logs that will be attached to a managed resource, in this case, a Vertex AI endpoint:
Code sample:
import logging
from google.api_core.client_options import ClientOptions
import google.cloud.logging_v2 as logging_v2
from google.oauth2 import service_account
def init_module_logger(module_name: str) -> logging.Logger:
module_logger = logging.getLogger(module_name)
module_logger.setLevel(settings.LOG_LEVEL)
credentials= service_account.Credentials.from_service_account_info(json.loads(SA_KEY_JSON))
client = logging_v2.client.Client(
credentials=credentials,
client_options=ClientOptions(api_endpoint="us-east1-aiplatform.googleapis.com"),
)
handler = client.get_default_handler(
resource=Resource(
type="aiplatform.googleapis.com/Endpoint",
labels={"endpoint_id": "ENDPOINT_NUMBER_ID",
"location": "us-east1"},
)
)
#Assume we have the formatter
handler.setFormatter(ENRICHED_FORMATTER)
module_logger.addHandler(handler)
return module_logger
logger = init_module_logger(__name__)
logger.info("This Fails with 501")
And i am getting:
google.api_core.exceptions.MethodNotImplemented: 501 The GRPC target
is not implemented on the server, host:
us-east1-aiplatform.googleapis.com, method:
/google.logging.v2.LoggingServiceV2/WriteLogEntries. Sent all pending
logs.
I thought we need to enable api and was told it's enabled, and that we have: https://www.googleapis.com/auth/logging.write
what could be causing the error?
As mentioned by #DazWilkin in the comment, the error is because the API endpoint us-east1-aiplatform.googleapis.com does not have a method called WriteLogEntries.
The above endpoint is used to send requests to Vertex AI services and not to Cloud Logging. The API endpoint to be used is the logging.googleapis.com as shown in the entries.write method. Refer to this documentation for more info.
The ClientOptions() function should have logging.googleapis.com as the api_endpoint parameter. If the client_options parameter is not specified, logging.googleapis.com is used by default.
After changing the api_endpoint parameter, I was able to successfully write the log entries. The ClientOptions() is as follows:
client = logging_v2.client.Client(
credentials=credentials,
client_options=ClientOptions(api_endpoint="logging.googleapis.com"),
)

How to create a bucket using the python SDK?

I'm trying to create a bucket in cloud object storage using python. I have followed the instructions in the API docs.
This is the code I'm using
COS_ENDPOINT = "https://control.cloud-object-storage.cloud.ibm.com/v2/endpoints"
# Create client
cos = ibm_boto3.client("s3",
ibm_api_key_id=COS_API_KEY_ID,
ibm_service_instance_id=COS_INSTANCE_CRN,
config=Config(signature_version="oauth"),
endpoint_url=COS_ENDPOINT
)
s3 = ibm_boto3.resource('s3')
def create_bucket(bucket_name):
print("Creating new bucket: {0}".format(bucket_name))
s3.Bucket(bucket_name).create()
return
bucket_name = 'test_bucket_442332'
create_bucket(bucket_name)
I'm getting this error - I tried setting CreateBucketConfiguration={"LocationConstraint":"us-south"}, but it doesnt seem to work
"ClientError: An error occurred (IllegalLocationConstraintException) when calling the CreateBucket operation: The unspecified location constraint is incompatible for the region specific endpoint this request was sent to."
Resolved by going to https://cloud.ibm.com/docs/cloud-object-storage?topic=cloud-object-storage-endpoints#endpoints
And choosing the endpoint specific to the region I need. The "Endpoint" provided with the credentials, is not the actual endpoint.

Google Cloud authorization keeps failing with Python 3 - Type is None, expected one of ('authorized_user', 'service_account')

I am trying to download a file for the first time from Google Cloud Storage.
I set the path to the googstruct.json service account key file that I downloaded from https://cloud.google.com/storage/docs/reference/libraries#client-libraries-usage-python
Do need to set the authorization to Google Cloud outside the code somehow? Or is there a better "How to use Google Cloud Storage" then the one on the google site?
It seems like I am passing the wrong type to the storage_client = storage.Client()
the exception string is below.
Exception has occurred: google.auth.exceptions.DefaultCredentialsError
The file C:\Users\Cary\Documents\Programming\Python\QGIS\GoogleCloud\googstruct.json does not have a valid type.
Type is None, expected one of ('authorized_user', 'service_account').
MY PYTHON 3.7 CODE
from google.cloud import storage
import os
os.environ["GOOGLE_APPLICATION_CREDENTIALS"]="C:\\GoogleCloud\\googstruct.json"
# Instantiates a client
storage_client = storage.Client()
bucket_name = 'structure_ssi'
destination_file_name = "C:\\Users\\18809_PIPEM.shp"
source_blob_name = '18809_PIPEM.shp'
download_blob(bucket_name, source_blob_name, destination_file_name)
def download_blob(bucket_name, source_blob_name, destination_file_name):
"""Downloads a blob from the bucket."""
storage_client = storage.Client()
bucket = storage_client.get_bucket(bucket_name)
blob = bucket.blob(source_blob_name)
blob.download_to_filename(destination_file_name)
print('Blob {} downloaded to {}.'.format(
source_blob_name,
destination_file_name
)
)
I did look at this but I cannot tell if this is my issue. I have tried both.
('Unexpected credentials type', None, 'Expected', 'service_account') with oauth2client (Python)
This error means that the Json Service Account Credentials that you are trying to use C:\\GoogleCloud\\googstruct.json are corrupt or the wrong type.
The first (or second) line in the file googstruct.json should be "type": "service_account".
Another few items to improve your code:
You do not need to use \\, just use / to make your code easier
and cleaner to read.
Load your credentials directly and do not modify environment
variables:
storage_client = storage.Client.from_service_account_json('C:/GoogleCloud/googstruct.json')
Wrap API calls in try / except. Stack traces do not impress customers. It is better to have clear, simple, easy to read error messages.

IBM - COS - SDK IAM token

I am trying to access my COS service using python.Referring IBM's Documentation was able to write the following code snippet
import ibm_boto3
from ibm_botocore.client import Config
api_key = 'key'
service_instance_id = 'resource-service-id'
auth_endpoint = 'http://iam.bluemix.net/'
service_endpoint = 'endpoint'
s3 = ibm_boto3.resource('s3',
ibm_api_key_id=api_key,
ibm_service_instance_id=service_instance_id,
ibm_auth_endpoint=auth_endpoint,
config=Config(signature_version='oauth'),
endpoint_url=service_endpoint)
s3.Bucket('bucket name').download_file('object name','location where the object must be saved')
Is this correct ? Also while trying to execute the above code the compiler is not able to retrieve the authentication token from auth_endpoint. Am i missing something?
Please to help
Thanks in advance!
I am including the output for your reference...
ibm_botocore.exceptions.CredentialRetrievalError: Error when retrieving credentials from https://iam.ng.bluemix.net/oidc/token: Retrieval of tokens from server failed
And I am using python 3.x
As instructed in README, the auth_endpoint should have /oidc/token at the end, for example, 'http://iam.bluemix.net/oidc/token'.
auth_endpoint = 'https://iam.bluemix.net/oidc/token'
The auth_endpoint should be https
See the example here
https://github.com/IBM/ibm-cos-sdk-python
To Connect with ibm cloud storage account we need api_key, service_instace_id,auth_endpoint and service_endpoint.
