Access s3 bucket from other region using java aws-java-sdk - spring-boot

I have s3 bucket from ap-south-1 which I have accessing using aws java sdk
AmazonS3 amazonS3 = AmazonS3ClientBuilder.standard(). withRegion(Regions.AP_SOUTH_1).defaultClient();
awazonS3.putObject(putObjectRequest);
It was working fine when my service is running in "ap-south-1". Now, when I move the service moved to "ap-south-2" reason same code is giving error.
The ap-south-1 location constraint is incompatible for the region specific endpoint this request was sent to. (Service: Amazon S3; Status Code: 400; Error Code: IllegalLocationConstraintException; Request ID: TTTTDW5T2GF0J28S8; S3 Extended Request ID: l3djAuSl5RXWgSLn12gTnyXyF1P7Q60OAMxTNhyrnmIJxIZ2MjRRzmOMT1hsEW6+KjqA=; Proxy: null)
currently i m using
`<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk</artifactId>
<version>1.12.145</version>
</dependency>`
I want to access same bucket of ap-south-1 in ap-south-2

The problem is you are using .defaultClient() which I think ignores the Region you set
Try using .build() instead which Builds a client with the configure properties.
so
AmazonS3 amazonS3 = AmazonS3ClientBuilder
.standard()
.withRegion(Regions.AP_SOUTH_1)
.build();
Note, you can also specify the S3 endpoint explicitly, as follows (but the above code is simpler):
AmazonS3 amazonS3 = AmazonS3ClientBuilder
.standard()
.withEndpointConfiguration(
new EndpointConfiguration("https://s3.ap-south-1.amazonaws.com", "ap-south-1"))
.build();

Lambda Layers not installing with Serverless

Currently getting the following error with MongoDB:
no saslprep library specified. Passwords will not be sanitized
We are using Webpack so simply installing the module doesn't work (Webpack just ignores it). I found this thread which talks about how to exclude it from Webpack compilations, but then I have to manually load it into every Lambda function which led me to Lambda Layers.
Following the Serverless guide on using Lambda layers allowed me to get my layer published to AWS and included in all of my functions, but for some reason, it doesn't install the modules. If I download the layer using the AWS GUI, I get a folder with just the package.json and package-lock.json files.
My file structure is:
my-project
|_ layers
|_ saslprep
|_ package.json
and my serverless.yml is:
layers:
saslprep:
path: layers/saslprep
compatibleRuntimes:
- nodejs14.x
This is not my preferred solution as I'd like to use 256, but the way I got around this error/warning was by changing the authMechanism from SCRAM-SHA-256 to SCRAM-SHA-1 in the connection string. The serverless-bundle most likely needs to add this dependency into their package to enable support for Mongo 4.0 SHA256 (my best guess!).
You can specify this authentication mechanism by setting the authMechanism parameter to the value SCRAM-SHA-1 in the connection string as shown in the following sample code.
const { MongoClient } = require("mongodb");
// Replace the following with values for your environment.
const username = encodeURIComponent("<username>");
const password = encodeURIComponent("<password>");
const clusterUrl = "<MongoDB cluster url>";
const authMechanism = "SCRAM-SHA-1";
// Replace the following with your MongoDB deployment's connection string.
const uri =
`mongodb+srv://${username}:${password}#${clusterUrl}/?authMechanism=${authMechanism}`;
// Create a new MongoClient
const client = new MongoClient(uri);
// Function to connect to the server
async function run() {
try {
// Connect the client to the server
await client.connect();
// Establish and verify connection
await client.db("admin").command({ ping: 1 });
console.log("Connected successfully to server");
} finally {
// Ensures that the client will close when you finish/error
await client.close();
}
}
run().catch(console.dir);

Configure Resource "aws_cloud_distribution" with ec2 as the origin with Terraform

I am setting up a "aws_cloud_distribution" with Terraform and attempting to set an ec2 as my origin.
In my module I have:
origin {
domain_name = var.domain_name
origin_id = var.origin_id
}
In the main file I call this module and use the output of the ec2 public dns.
module "cloudfront" {
source = "./modules/cloudfront"
domain_name = module.ec2.ec2_public_dns
origin_id = "myid"
target_origin_id = "myid"
}
When I run plan, I have no issues. However when I run apply and begin the build process I get the following error:
error creating CloudFront Distribution: InvalidArgument: The parameter
Origin DomainName does not refer to a valid S3 bucket.
status code: 400
I am using terraform 0.13.6 out of some company restrictions to other infra in the company. Is this a Terraform version issue or am I missing something in my configuration steps?
So, I figured out this issue by adding the custom_origin_config argument within the origin argument. The solution looks like the following:
origin {
domain_name = var.domain_name
origin_id = var.origin_id
custom_origin_config {
http_port = 80
https_port = 443
origin_protocol_policy = "match-viewer"
origin_ssl_protocols = ["TLSv1"]
}
}
Terraform defaults to S3 origin if you don't define the custom_origin_config argument. The AWS plugin for Terraform is searching for an s3 bucket and not an AWS FQDN to resolve.

Fog/aws gem for IBM Cloud Object Storage is not working

As Softlayer or IBM Cloud has moved from Swift based Object Storage to S3 based Cloud Object Storage. I am using fog/aws instead of fog/softlayer.
The below is the code:
require 'fog/aws'
fog_properties = {
provider: 'AWS',
aws_access_key_id: username,
aws_secret_access_key: api_key
}
#client = Fog::Storage.new(fog_properties)
#client.directories
But it failed even with valid key and id.
<Error><Code>InvalidAccessKeyId</Code><Message>The AWS Access Key Id you provided does not exist in our records.\</Message><AWSAccessKeyId>####</AWSAccessKeyId><RequestId>####</RequestId><HostId>##</HostId></Error>
End Point IBM COS uses is "https://control.cloud-object-storage.cloud.ibm.com/v2/endpoints"
When I tried to use fog alone(require 'fog'). It throws the below error:
Unable to activate google-api-client-0.23.9, because mime-types-2.99.3 conflicts with mime-types (~> 3.0) (Gem::ConflictError)
Please suggest how to resolve these issues.
https://control.cloud-object-storage.cloud.ibm.com/v2/endpoints"
This is not an endpoint but a list of endpoints in JSON.
Choose the endpoint for your bucket location.
For example if your bucket is in us-south the public endpoint is
https://s3.us-south.cloud-object-storage.appdomain.cloud
The following code worked for IBM Cloud Objects Storage
properties = {
region: region,
endpoint: URI('https://s3.us-south.cloud-object-storage.appdomain.cloud'),
credentials: Aws::Credentials.new(access_key_id, secret_access_key)
}
Aws.config.update(properties)
#client = Aws::S3::Client.new
Properties for the config can also be set as ENV variables.
Below are few basic operations performed on COS.
List all the bucker names
#client.list_buckets.buckets.map(&:name)
Create Bucket
#client.create_bucket(bucket: )
Upload a file
#client.put_object(bucket: , key: , body: )
Download a file
#client.get_object(bucket: , key: )
Delete a file
#client.delete_object(bucket: , key: )
Delete a Bucket
#client.delete_bucket(bucket: )

Postman AWS S3 snapshot request Elasticsearch

Hello I need some help with sending a PUT request to my ElasticSearch on AWS to create a snapshot in a S3 bucket, with POSTMAN.
I have created a S3 bucket called cb-search-es-backup.
I've created a role, and a policy for S3 (see:this post of mine for the steps I've taken).
REQUEST URL https://myelasticsearchendpoint.eu-west-1.es.amazonaws.com/
REQUEST METHOD: PUT
BODY : RAW / json
{
"type": "s3",
"settings": {
"bucket": "cb-search-es-backup", // my bucketname
"region": "eu-west-1", // region
"role_arn": "arn:aws:iam::12345676890:role/Role_ES_TO_S3" // my role arn
}
}
I've also tried the authorization type: 'AWS Signature', with access and secret key filled in.
It looks like you are not passing AWS credentials with this request.
There is a detailed guide how to make a Postman request with AWS authentication here: Use Postman to Call an API.
Your Postman window might look like this:
To do the same from python please check out Sample python client section of this documentation page, note that AWS4Auth object is created and it's passed as auth parameter to requests.put():
credentials = boto3.Session().get_credentials()
awsauth = AWS4Auth(credentials.access_key, credentials.secret_key, region, service, session_token=credentials.token)
# Register repository
path = '_snapshot/my-snapshot-repo' # the Elasticsearch API endpoint
url = host + path
payload = {
...
}
headers = {"Content-Type": "application/json"}
r = requests.put(url, auth=awsauth, json=payload, headers=headers)

The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256

I get an error AWS::S3::Errors::InvalidRequest The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256. when I try upload file to S3 bucket in new Frankfurt region. All works properly with US Standard region.
Script:
backup_file = '/media/db-backup_for_dev/2014-10-23_02-00-07/slave_dump.sql.gz'
s3 = AWS::S3.new(
access_key_id: AMAZONS3['access_key_id'],
secret_access_key: AMAZONS3['secret_access_key']
)
s3_bucket = s3.buckets['test-frankfurt']
# Folder and file name
s3_name = "database-backups-last20days/#{File.basename(File.dirname(backup_file))}_#{File.basename(backup_file)}"
file_obj = s3_bucket.objects[s3_name]
file_obj.write(file: backup_file)
aws-sdk (1.56.0)
How to fix it?
Thank you.
AWS4-HMAC-SHA256, also known as Signature Version 4, ("V4") is one of two authentication schemes supported by S3.
All regions support V4, but US-Standard¹, and many -- but not all -- other regions, also support the other, older scheme, Signature Version 2 ("V2").
According to http://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html ... new S3 regions deployed after January, 2014 will only support V4.
Since Frankfurt was introduced late in 2014, it does not support V2, which is what this error suggests you are using.
http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingAWSSDK.html explains how to enable V4 in the various SDKs, assuming you are using an SDK that has that capability.
I would speculate that some older versions of the SDKs might not support this option, so if the above doesn't help, you may need a newer release of the SDK you are using.
¹US Standard is the former name for the S3 regional deployment that is based in the us-east-1 region. Since the time this answer was originally written,
"Amazon S3 renamed the US Standard Region to the US East (N. Virginia) Region to be consistent with AWS regional naming conventions." For all practical purposes, it's only a change in naming.
With node, try
var s3 = new AWS.S3( {
endpoint: 's3-eu-central-1.amazonaws.com',
signatureVersion: 'v4',
region: 'eu-central-1'
} );
You should set signatureVersion: 'v4' in config to use new sign version:
AWS.config.update({
signatureVersion: 'v4'
});
Works for JS sdk.
For people using boto3 (Python SDK) use the below code
from botocore.client import Config
s3 = boto3.resource(
's3',
aws_access_key_id='xxxxxx',
aws_secret_access_key='xxxxxx',
config=Config(signature_version='s3v4')
)
I have been using Django, and I had to add these extra config variables to make this work. (in addition to settings mentioned in https://simpleisbetterthancomplex.com/tutorial/2017/08/01/how-to-setup-amazon-s3-in-a-django-project.html).
AWS_S3_REGION_NAME = "ap-south-1"
Or previous to boto3 version 1.4.4:
AWS_S3_REGION_NAME = "ap-south-1"
AWS_S3_SIGNATURE_VERSION = "s3v4"
Similar issue with the PHP SDK, this works:
$s3Client = S3Client::factory(array('key'=>YOUR_AWS_KEY, 'secret'=>YOUR_AWS_SECRET, 'signature' => 'v4', 'region'=>'eu-central-1'));
The important bit is the signature and the region
AWS_S3_REGION_NAME = "ap-south-1"
AWS_S3_SIGNATURE_VERSION = "s3v4"
this also saved my time after surfing for 24Hours..
Code for Flask (boto3)
Don't forget to import Config. Also If you have your own config class, then change its name.
from botocore.client import Config
s3 = boto3.client('s3',config=Config(signature_version='s3v4'),region_name=app.config["AWS_REGION"],aws_access_key_id=app.config['AWS_ACCESS_KEY'], aws_secret_access_key=app.config['AWS_SECRET_KEY'])
s3.upload_fileobj(file,app.config["AWS_BUCKET_NAME"],file.filename)
url = s3.generate_presigned_url('get_object', Params = {'Bucket':app.config["AWS_BUCKET_NAME"] , 'Key': file.filename}, ExpiresIn = 10000)
In Java I had to set a property
System.setProperty(SDKGlobalConfiguration.ENFORCE_S3_SIGV4_SYSTEM_PROPERTY, "true")
and add the region to the s3Client instance.
s3Client.setRegion(Region.getRegion(Regions.EU_CENTRAL_1))
With boto3, this is the code :
s3_client = boto3.resource('s3', region_name='eu-central-1')
or
s3_client = boto3.client('s3', region_name='eu-central-1')
For thumbor-aws, that used boto config, i needed to put this to the $AWS_CONFIG_FILE
[default]
aws_access_key_id = (your ID)
aws_secret_access_key = (your secret key)
s3 =
signature_version = s3
So anything that used boto directly without changes, this may be useful
Supernova answer for django/boto3/django-storages worked with me:
AWS_S3_REGION_NAME = "ap-south-1"
Or previous to boto3 version 1.4.4:
AWS_S3_REGION_NAME = "ap-south-1"
AWS_S3_SIGNATURE_VERSION = "s3v4"
just add them to your settings.py and change region code accordingly
you can check aws regions from:
enter link description here
For Android SDK, setEndpoint solves the problem, although it's been deprecated.
CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
context, "identityPoolId", Regions.US_EAST_1);
AmazonS3 s3 = new AmazonS3Client(credentialsProvider);
s3.setEndpoint("s3.us-east-2.amazonaws.com");
Basically the error was because I was using old version of aws-sdk and I updated the version so this error occured.
in my case with node js i was using signatureVersion in parmas object like this :
const AWS_S3 = new AWS.S3({
params: {
Bucket: process.env.AWS_S3_BUCKET,
signatureVersion: 'v4',
region: process.env.AWS_S3_REGION
}
});
Then I put signature out of params object and worked like charm :
const AWS_S3 = new AWS.S3({
params: {
Bucket: process.env.AWS_S3_BUCKET,
region: process.env.AWS_S3_REGION
},
signatureVersion: 'v4'
});
Check your AWS S3 Bucket Region and Pass proper Region in Connection Request.
In My Senario I have set 'APSouth1' for Asia Pacific (Mumbai)
using (var client = new AmazonS3Client(awsAccessKeyId, awsSecretAccessKey, RegionEndpoint.APSouth1))
{
GetPreSignedUrlRequest request1 = new GetPreSignedUrlRequest
{
BucketName = bucketName,
Key = keyName,
Expires = DateTime.Now.AddMinutes(50),
};
urlString = client.GetPreSignedURL(request1);
}
In my case, the request type was wrong. I was using GET(dumb) It must be PUT.
Here is the function I used with Python
def uploadFileToS3(filePath, s3FileName):
s3 = boto3.client('s3',
endpoint_url=settings.BUCKET_ENDPOINT_URL,
aws_access_key_id=settings.BUCKET_ACCESS_KEY_ID,
aws_secret_access_key=settings.BUCKET_SECRET_KEY,
region_name=settings.BUCKET_REGION_NAME
)
try:
s3.upload_file(
filePath,
settings.BUCKET_NAME,
s3FileName
)
# remove file from local to free up space
os.remove(filePath)
return True
except Exception as e:
logger.error('uploadFileToS3#Error')
logger.error(e)
return False
Sometime the default version will not update. Add this command
AWS_S3_SIGNATURE_VERSION = "s3v4"
in settings.py
For Boto3 , use this code.
import boto3
from botocore.client import Config
s3 = boto3.resource('s3',
aws_access_key_id='xxxxxx',
aws_secret_access_key='xxxxxx',
region_name='us-south-1',
config=Config(signature_version='s3v4')
)
Try this combination.
const s3 = new AWS.S3({
endpoint: 's3-ap-south-1.amazonaws.com', // Bucket region
accessKeyId: 'A-----------------U',
secretAccessKey: 'k------ja----------------soGp',
Bucket: 'bucket_name',
useAccelerateEndpoint: true,
signatureVersion: 'v4',
region: 'ap-south-1' // Bucket region
});
I was stuck for 3 days and finally, after reading a ton of blogs and answers I was able to configure Amazon AWS S3 Bucket.
On the AWS Side
I am assuming you have already
Created an s3-bucket
Created a user in IAM
Steps
Configure CORS settings
you bucket > permissions > CORS configuration
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
<AllowedOrigin>*</AllowedOrigin>
<AllowedMethod>GET</AllowedMethod>
<AllowedMethod>POST</AllowedMethod>
<AllowedMethod>PUT</AllowedMethod>
<AllowedHeader>*</AllowedHeader>
</CORSRule>
</CORSConfiguration>```
Generate A bucket policy
your bucket > permissions > bucket policy
It should be similar to this one
{
"Version": "2012-10-17",
"Id": "Policy1602480700663",
"Statement": [
{
"Sid": "Stmt1602480694902",
"Effect": "Allow",
"Principal": "*",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::harshit-portfolio-bucket/*"
}
]
}
PS: Bucket policy should say `public` after this
Configure Access Control List
your bucket > permissions > acces control list
give public access
PS: Access Control List should say public after this
Unblock public Access
your bucket > permissions > Block Public Access
Edit and turn all options Off
**On a side note if you are working on django
add the following lines to you settings.py file of your project
**
#S3 BUCKETS CONFIG
AWS_ACCESS_KEY_ID = '****not to be shared*****'
AWS_SECRET_ACCESS_KEY = '*****not to be shared******'
AWS_STORAGE_BUCKET_NAME = 'your-bucket-name'
AWS_S3_FILE_OVERWRITE = False
AWS_DEFAULT_ACL = None
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'
# look for files first in aws
STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'
# In India these settings work
AWS_S3_REGION_NAME = "ap-south-1"
AWS_S3_SIGNATURE_VERSION = "s3v4"
Also coming from: https://simpleisbetterthancomplex.com/tutorial/2017/08/01/how-to-setup-amazon-s3-in-a-django-project.html
For me this was the solution:
AWS_S3_REGION_NAME = "eu-central-1"
AWS_S3_ADDRESSING_STYLE = 'virtual'
This needs to be added to settings.py in your Django project
Using PHP SDK Follow Below.
require 'vendor/autoload.php';
use Aws\S3\S3Client;
use Aws\S3\Exception\S3Exception;
$client = S3Client::factory(
array(
'signature' => 'v4',
'region' => 'me-south-1',
'key' => YOUR_AWS_KEY,
'secret' => YOUR_AWS_SECRET
)
);
Nodejs
var aws = require("aws-sdk");
aws.config.update({
region: process.env.AWS_REGION,
secretAccessKey: process.env.AWS_S3_SECRET_ACCESS_KEY,
accessKeyId: process.env.AWS_S3_ACCESS_KEY_ID,
});
var s3 = new aws.S3({
signatureVersion: "v4",
});
let data = await s3.getSignedUrl("putObject", {
ContentType: mimeType, //image mime type from request
Bucket: "MybucketName",
Key: folder_name + "/" + uuidv4() + "." + mime.extension(mimeType),
Expires: 300,
});
console.log(data);
AWS S3 Bucket Permission Configuration
Deselect Block All Public Access
Add Below Policy
{
"Version":"2012-10-17",
"Statement":[{
"Sid":"PublicReadGetObject",
"Effect":"Allow",
"Principal": "*",
"Action":["s3:GetObject"],
"Resource":["arn:aws:s3:::MybucketName/*"
]
}
]
}
Then Paste the returned URL and make PUT request on the URL with binary file of image
Full working nodejs version:
const AWS = require('aws-sdk');
var s3 = new AWS.S3( {
endpoint: 's3.eu-west-2.amazonaws.com',
