Boto3 Error: botocore.exceptions.NoCredentialsError: Unable to locate credentials
Solution 1:
try specifying keys manually
s3 = boto3.resource('s3',
aws_access_key_id=ACCESS_ID,
aws_secret_access_key= ACCESS_KEY)
Make sure you don't include your ACCESS_ID
and ACCESS_KEY
in the code directly for security concerns.
Consider using environment configs and injecting them in the code as suggested by @Tiger_Mike.
For Prod environments consider using rotating access keys: https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html#Using_RotateAccessKey
Solution 2:
I had the same issue and found out that the format of my ~/.aws/credentials
file was wrong.
It worked with a file containing:
[default]
aws_access_key_id=XXXXXXXXXXXXXX
aws_secret_access_key=YYYYYYYYYYYYYYYYYYYYYYYYYYY
Note that there must be a profile name "[default]
". Some official documentation make reference to a profile named "[credentials]
", which did not work for me.
Solution 3:
If you are looking for an alternative way, try adding your credentials using AmazonCLI
from the terminal type:-
aws configure
then fill in your keys and region.
Solution 4:
Make sure your ~/.aws/credentials file in Unix looks like this:
[MyProfile1]
aws_access_key_id = yourAccessId
aws_secret_access_key = yourSecretKey
[MyProfile2]
aws_access_key_id = yourAccessId
aws_secret_access_key = yourSecretKey
Your Python script should look like this, and it'll work:
from __future__ import print_function
import boto3
import os
os.environ['AWS_PROFILE'] = "MyProfile1"
os.environ['AWS_DEFAULT_REGION'] = "us-east-1"
ec2 = boto3.client('ec2')
# Retrieves all regions/endpoints that work with EC2
response = ec2.describe_regions()
print('Regions:', response['Regions'])

Solution 5:
I also had the same issue,it can be solved by creating a config and credential file in the home directory. Below show the steps I did to solve this issue.
Create a config file :
touch ~/.aws/config
And in that file I entered the region
[default]
region = us-west-2
Then create the credential file:
touch ~/.aws/credentials
Then enter your credentials
[Profile1]
aws_access_key_id = XXXXXXXXXXXXXXXXXXXX
aws_secret_access_key = YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
After set all these, then my python file to connect bucket. Run this file will list all the contents.
import boto3
import os
os.environ['AWS_PROFILE'] = "Profile1"
os.environ['AWS_DEFAULT_REGION'] = "us-west-2"
s3 = boto3.client('s3', region_name='us-west-2')
print("[INFO:] Connecting to cloud")
# Retrieves all regions/endpoints that work with S3
response = s3.list_buckets()
print('Regions:', response)
