AWS Fargate Task scenarios to Access S3 Bucket with '403 Forbidden' scenarios Despite Role Permissions
I'm reviewing some code and I've hit a wall trying to I'm attempting to set up Hey everyone, I'm running into an issue that's driving me crazy... I'm trying to deploy a microservice on AWS Fargate that needs to access an S3 bucket. I've created an IAM role with the following policy allowing access to the specific S3 bucket: ```json { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": ["s3:GetObject", "s3:PutObject"], "Resource": "arn:aws:s3:::my-bucket/*" } ] } ``` I've attached this role to my Fargate task definition. However, when the task runs, I receive a `403 Forbidden` behavior when trying to perform operations on S3. I confirmed that the bucket policy allows access from the IAM role's ARN: ```json { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": {"AWS": "arn:aws:iam::123456789012:role/my-fargate-role"}, "Action": "s3:*", "Resource": "arn:aws:s3:::my-bucket/*" } ] } ``` I've checked that the task is indeed using the correct role and also confirmed that the VPC configuration allows the task to access the S3 endpoint. I even tried using the AWS CLI inside a shell in the Fargate task to list the objects in the bucket, but I still get the same `403 Forbidden` behavior. I've also looked through the CloudTrail logs, but there’s no indication of what’s going wrong. Could someone point me in the right direction? Is there something I'm missing in the permissions or configuration that could be causing this scenario? Any advice would be greatly appreciated. I'm working on a web app that needs to handle this. Any ideas what could be causing this? For reference, this is a production microservice. How would you solve this? My team is using Json for this desktop app.
