I have created an s3 bucket in aws and added the correct permissions and user group etc. I have added the below policy:

    "Version": "2012-10-17",
    "Statement": [
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
            "Resource": "*"
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": [
            "Resource": "arn:aws:s3:::bucketname"

I uploaded the assets from a local folder via ftp to the bucket using transmit ftp client which was fine. I have then set the bucket up on craft cms as an asset source. I can upload files to s3 via the cms fine with no issues and view the image fine but when I try to access an image on the front end that was uploaded via the ftp I get access denied error 403:

<Message>Access Denied</Message>

edit here

So after some research I found out that you needed to add the policy directly to the bucket. You used to have to create a policy away from the bucket page itself in the IAM area but now(I think) it needs to be in the bucket.

Is this a policy issue?



I'm not really an AWS expert, but I think if you want to allow public access to an S3 bucket, then it should look something like this:

    "Sid": "PublicReadGetObject",
    "Effect": "Allow",
    "Principal": "*",
    "Action": "s3:GetObject",
    "Resource": "arn:aws:s3:::bucketname/*"
  • Hey Brad, not sure if this works when you have moved files from dev onto the bucket via ftp. Funnily enough if I upload a file from Craft on the bucket I can view it no problem. Thats down to the fact that the policy must only work for that user when uploaded to the cns – M dunbavan May 18 '18 at 9:35
  • It should work for either? Did you try it? – Brad Bell May 18 '18 at 18:14
  • Does the Sid you have there hold importance? So is it important to have that particular Sid? – M dunbavan May 18 '18 at 18:17
  • Nah, that can be whatever you want to call it. – Brad Bell May 18 '18 at 18:17
  • Nah that still throws 403 error s3-us-west-1.amazonaws.com/viaduct.co.uk/M-D-C-Assets/… – M dunbavan May 18 '18 at 18:28
