What I am trying to do:
Use Eventbridge to schedule an AWS Batch job to run daily.
The problem:
I've created a rule in Eventbridge for a working AWS batch job., but it's is not being kicked off at the scheduled time.
The only thing that I can think of that is going wrong is maybe I don't have the correct role type, trust relationship and policy for the rule? Any help provided would be greatly appreciated, thank you!
Role Information
Role use case type: Allows EC2 instances to call aws services on your behalf

I am using active storage (on s3) for saving resources of my app (rails). i need generate url for existing images with changed size - i used for it - Rails.application.routes.url_helpers.rails_representation_url(column.variant(resize: '250x250').processed, only_path: true, disposition: :inline)
But in this peace of code - column.variant(resize: '250x250').processed returns
Aws::S3::Errors::Forbidden (Aws::S3::Errors::Forbidden)
backet policy
{
"Version": "2012-10-17",
"Id": "Policy*****4140",
"Statement": [
{
"Sid": "Stmt*******38628",
"Effect": "Allow",
"Principal": {
"AWS": "*"
},
"Action": "s3:GetObject",
"Resource": [
"arn:aws:s3:::my_project/*"
]
}
]
}
How can i fix it?
I try to allow one of our Devs (myapp-dev1) the access to one explicit S3-Bucket.
I created a policy which should allow CRUD options (he should be able to write and read image files into that bucket, and only into this.
"s3:PutObject",
"s3:GetObject",
"s3:DeleteObject",
"s3:ListObjects"
I created a User named dev1 and assigned him to that new policy (the user is not in a Group nor has a Role)
I created a Bucket named accordingly ARN: arn:aws:s3:::myapp-dev1-bucket
Then in this bucket I switched to "Bucket Policy" and used the "Policy Generator" and allowed every action for that moment. All other settings failed so far, this one too. It looks like this:
{
"Id": "Policy123456789",
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmt123456789",
"Action": "s3:*",
"Effect": "Allow",
"Resource": "arn:aws:s3:::myapp-dev1-bucket",
"Principal": {
"AWS": [
"arn:aws:iam::1234567890:user/myapp-dev1"
]
}
}
]
}
But I still get an
Excon::Error::Forbidden: Expected(200) <=> Actual(403 Forbidden)
What I have done wrong?
What I am missing?
Does the User must also be allowed to list buckets?
Please help!
Try this,
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"s3:ListBucket"
],
"Resource": [
"arn:aws:s3:::Bucket_Name"
]
},
{
"Effect": "Allow",
"Action": [
"s3:PutObject",
"s3:GetObject",
"s3:DeleteObject",
"s3:ListObject"
],
"Resource": [
"arn:aws:s3:::Bucket_Name/*"
]
}
]
}
For the last month, I've been successfully using Cognito with the iOS SDK to upload and download files from an s3 bucket in my app. I recently created a new bucket in which to store the files instead, and I suddenly can't download anything (although uploads continue to work). I get this error:
Error downloading from S3: Error Domain=com.amazonaws.AWSS3ErrorDomain
Code=1 "The operation couldn’t be completed.
(com.amazonaws.AWSS3ErrorDomain error 1.)" UserInfo=0x157da330
{HostId=xlPbd8nAQvYPesh0JZ5yH7LFuV562FK85qd5MEgg3DNXn9U0m1K6e8kji
CsC4NXf, Code=AccessDenied, Message=Access Denied,
RequestId=EF39DF70A50540EA}
I'm using exactly the same configuration as I was with the old bucket, with the name of the new bucket changed where it needs to be.
Here's the Unauth IAM policy I've been using:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"mobileanalytics:PutEvent",
"cognito-sync:*"
],
"Resource": [
"*"
]
},
{
"Action": [
"s3:GetObject",
"s3:PutObject"
],
"Effect": "Allow",
"Resource": [
"*"
]
}
]
}
And here's my bucket policy:
{
"Version": "2008-10-17",
"Statement": [
{
"Sid": "AllowPublicRead",
"Effect": "Allow",
"Principal": {
"AWS": "*"
},
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::bucket_name/*"
}
]
}
The new bucket is the same region as the old. Right now, I'm at a complete loss as to what simply changing to a new bucket changed (and why uploads work, but downloads don't). If it's relevant, my files are now being stored in a subdirectory of the bucket, but I've updated all the key strings on the client. Thank you very much for your help.
I see your resource in the IAM policy is set to *. Try being explicit about the resource in your IAM policy
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"s3:ListBucket"
],
"Resource": [
"arn:aws:s3:::mybucketname"
]
},
{
"Effect": "Allow",
"Action": [
"s3:PutObject",
"s3:GetObject",
"s3:DeleteObject"
]
}
]
}
I have a paperclip text file attachment (in Rails).
My bucket policy is:
{
"Version": "2008-10-17",
"Id": "Policy123",
"Statement": [
{
"Sid": "Stmt123",
"Effect": "Allow",
"Principal": {
"AWS": "*"
},
"Action": [
"s3:GetObjectVersion",
"s3:DeleteObject",
"s3:DeleteObjectVersion",
"s3:GetObject",
"s3:PutObject"
],
"Resource": "arn:aws:s3:::my_bucket/*"
}
]
}
I want to restrict access to these actions to only be allowed when the request comes from my website. Is it simply a case of updating this to: "Principal": {"AWS": "mywebsite.com"} ?
You can check some examples in S3 Documentations
To restrict the access from your web site, you can use the condition on Referrer:
{
"Version":"2008-10-17",
"Id":"http referer policy example",
"Statement":[
{
"Sid":"Allow get requests referred by www.mysite.com and mysite.com",
"Effect":"Allow",
"Principal":"*",
"Action":"s3:GetObject",
"Resource":"arn:aws:s3:::example-bucket/*",
"Condition":{
"StringLike":{
"aws:Referer":[
" http://www.mysite.com/*",
" http://mysite.com/*"
]
}
}
}
]
}
Bucket policy :
{
"Version": "2012-10-17",
"Id": "http referer policy example",
"Statement": [
{
"Sid": "Allow get requests originating from www.example.com and example.com.",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::00000000:user/example-user" // IAM User ARN
},
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::bucket-example/*", // bucket ARN
"Condition": {
"StringLike": {
"aws:Referer": [
"http://example.com/*" // Website link
]
}
}
}
]
}
