s3 put json file access denied

Question

I am using linux s3cmd to upload files to AWS S3. I can upload a zip file successfully and this has been working for months now, no problems. I now need to also upload a json file. When I try to upload the json file to the same bucket, I get S3 error: Access Denied. I can't figure out why, please help.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:ListBucket"
            ],
            "Resource": [
                "arn:aws:s3:::mybucket"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:DeleteObject"
            ],
            "Resource": [
                "arn:aws:s3:::mybucket/*"
            ]
        }
    ]
}

s3cmd --mime-type=application/zip put myfile.zip s3://mybucket
SUCCESS

s3cmd --mime-type=application/json put myfile.json s3://mybucket
ERROR: S3 error: Access Denied

These days, it is recommended to use the AWS Command-Line Interface (CLI) rather than s3cmd.

The aws s3 cp command will try to automatically guess the mime type, so you might not need to specify it as in your example.

If your heart is set on figuring out why s3cmd doesn't work, try opening up permissions (eg allow s3:*) to see if this fixes things, then narrow-down the list of permitted API calls to figure out which one s3cmd is calling.

Thanks for the response. I had tried changing the allow action to all ("*") already with no change. – user3720435 Jun 22 '16 at 03:35

Alternatively you can use Minio client aka mc Using mc cp command this can be done.

$ mc cp myfile.json s3alias/mybucket

Hope it helps.
