I have setup AWS CloudFront and S3 as it's origin.
I have made the files I want to access in the bucket public, but I am getting a 403 Forbidden error/Access denied XML when I try to access these files.
A link is simply:
http://dd9rhibbjdy7s.cloudfront.net/assets123/app.js
I have Googled everywhere but still can't find the solution.
Does any one have a clue how to get this working?
The exact response when browsing to it is:
<Error>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
<RequestId>74E36027507DACD6</RequestId>

Add this bucket policy to your S3 Bucket, remember to change the bucket name.
{
"Version":"2008-10-17",
"Statement":[{
"Sid":"AllowPublicRead",
"Effect":"Allow",
"Principal": {
"AWS": "*"
},
"Action":["s3:GetObject"],
"Resource":["arn:aws:s3:::YOUR-BUCKET-NAME/*"
]
}
]
}
One of my collegues suggested I use the policy generator and came up with this:
{
"Id": "Policy1439469599074",
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmt1439469594186",
"Action": [
"s3:GetObject"
],
"Effect": "Allow",
"Resource": "arn:aws:s3:::assets123/*",
"Principal": "*"
}
]
}
Which has made it all work :)

I uploaded a pdf version file into the AWS s3 bucket bucket and then tried to open that object url using Google Chrome. The following error occurred. How to fix this issue?
This XML file does not appear to have any style information associated with it. The document tree is shown below.

Please make sure that your bucket is publically accessible in the Permissions tab
Use the following as your bucket policy: (please use your bucket name in the Resource field)
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "PublicReadGetObject",
"Effect": "Allow",
"Principal": "*",
"Action": [
"s3:GetObject"
],
"Resource": [
"arn:aws:s3:::Bucket-Name/*"
]
}
]
}
Now see if it works. Please let us know.

I use [django-s3direct][1] to upload file to S3 bucket.
Once file is uploaded there comes url appeares here.
https://s3.ap-northeast-1.amazonaws.com/cdk-sample-bk/line-assets/images/e236fc508939466a96df6b6066f418ec/1040
However when accessing from browser, the error comes.
<Error>
<script/>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
<RequestId>025WQBJQ5K2W5Z5W</RequestId>
<HostId>FF3VeIft8zSQ7mRK1a5e4l8jolxHBB40TEh6cPhW0qQtDqT7k3ptgCQt3/nusiehDIXkgvxXkcc=</HostId>
</Error>
Now I can use s3.ap-northeast-1.amazonaws.com url? or do I need to create access point ?
Access permission is public and bloc public access is off
Bucket policy is like this
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::678100228133:role/st-dev-base-stack-CustomS3AutoDeleteObjectsCustomR-MLBJDQF3OWFJ"
},
"Action": [
"s3:GetBucket*",
"s3:List*",
"s3:DeleteObject*"
],
"Resource": [
"arn:aws:s3:::cdk-st-dev-sample-bk",
"arn:aws:s3:::cdk-st-dev-sample-bk/*"
]
}
]
}
Is there any other things I need to check?
As #marcin said you bucket policy only allows the actions for the IAM role arn:aws:iam::678100228133:role/st-dev-base-stack-CustomS3AutoDeleteObjectsCustomR-MLBJDQF3OWFJ. If you want to have all your objects accessible to the public (would not recommend write) you need change your bucket policy as following -
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": "*",
"Action": [
"s3:GetBucket*",
"s3:GetObject",
"s3:List*",
"s3:DeleteObject*"
],
"Resource": [
"arn:aws:s3:::cdk-st-dev-sample-bk",
"arn:aws:s3:::cdk-st-dev-sample-bk/*"
]
}
]
}
The above policy makes all of your bucket objects accessible to the public (also allows the public to delete them!!). My recommendation will be using django-storages and presigned urls allow your users to access your bucket objects.
Consider the following policy in S3 :
{
"Version": "2012-10-17",
"Id": "AxelPolly12424242",
"Statement": [
{
"Sid": "Stmt242554354",
"Effect": "Allow",
"Principal": "*",
"Action": ["s3:ListBucket"],
"Resource": "arn:aws:s3:::mycoolbucketname/*",
"Condition":{"StringEquals":{"s3:prefix":["","examples"]}}
}
]
}
When I try to hit my bucket name https://mycoolbucketname.s3-us-east-2.amazonaws.com/examples:
we get:
<Error>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
<RequestId>KJLFSDHJJKGDFJKLGJDFKLGJLDF</RequestId>
<HostId>GLKSFDNGJKLFDJGKLDFJGKLFDJGFDGEOT89GJROIGIKDSFSDJSD</HostId>
</Error>
What's wrong with this policy and how can we list all subfolders of a bucket , when we've also unchecked
Block public access (bucket settings) under Permissions tab.
s3:prefix applies to bucket resources, not objects. So instead of:
"Resource": "arn:aws:s3:::mycoolbucketname/*",
you should have:
"Resource": "arn:aws:s3:::mycoolbucketname",
Amazon s3 I have created a bucket and set cloudwatch.Logs are being generated for audit and trace. But with s3, able to share individual file download links only. Any option to set complete bucket /folder to public and users can access that? I tried updating bucket policy but no use.
Policy I tried.
{
"Id": "Policy1397632521960",
"Statement": [
{
"Sid": "Stmt1397633323327",
"Action": [
"s3:GetObject"
],
"Effect": "Allow",
"Resource": "arn:aws:s3:::bucketnm/*",
"Principal": {
"AWS": [
"*"
]
}
}
]
}
But still below issue.

My goal is to upload a jpg file to s3 bucket and I've done using boto3 library.
When I was trying to open that file in s3 bucket using the displayed link I'm facing an error.

Edit1:
After following answer suggested by #CaffeinatedCod3r, I'm getting following error.
It looks like you are trying to view the image in browser.
For that, you need to
Open the S3 object in your AWS.
Go to properties of the S3 object.
Go to Metadata section.
There will be a property called Content-Type. It's initial value might be binary/stream. Change that to the type of image like image/jpeg, image/png
or application/pdf (if you are dealing with pdf files) etc.
Now you should be able to view the image or file in the browser tab instead of downloading.
Before you download a file using generated web URL, you need to apply public permissions using "bucket policy" tool.
In order to apply the bucket policy, perform the following steps:
Open S3 management console https://console.aws.amazon.com/s3/
Choose a bucket, click "Permissions", click "Bucket policy".
Apply the policy using AWS policy generator.
You have to apply policy for GetObject.
Note:This will give download permission to everyone who have got the link.
A sample policy would look like this
{
"Id": "PolicyID",
"Version": "2012-10-17",
"Statement": [
{
"Sid": "StmtID",
"Action": [
"s3:GetObject"
],
"Effect": "Allow",
"Resource": "arn:aws:s3:::<YOUR_BUCKET_NAME>",
"Principal": "*"
}
]
}
Edit after #mondyfy answer the policy would be
{
"Id": "PolicyID",
"Version": "2012-10-17",
"Statement": [
{
"Sid": "StmtID",
"Action": [
"s3:GetObject"
],
"Effect": "Allow",
"Resource": "arn:aws:s3:::<YOUR_BUCKET_NAME>/*",
"Principal": "*"
}
]
}
I have also got a similar issue following the answer suggested by #CaffeinatedCod3r, Here I have a slight update on the above answer and it's working, maybe it will be helpful for others:
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "PublicRead",
"Effect": "Allow",
"Principal": "*",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::<YOUR_BUCKET_NAME>/*"
}
]
}
Note: In order to view any bucket object in the browser we need to make sure that we have to set Content-Type of media that the browser needs to render as suggested by #Jarvis and object or bucket should have public read access.
