Johannes Weißl 89a2389586 Correct documentation of S3 bucket
Documentation added in aaf034b on Nov 17th 2016 says the S3 bucket can
be specified with `s3.bucket`, but commit c8bcc4c (#285) on Dec 18th
2016 used `s3bucket`. Instead of fixing the code (#552) to match the
documentation this commit changes just the documentation so that
existing configurations are not broken. Also, the `s3` object is passed
as is to `AWS.S3()`, which does not know the option `bucket` (but
silently ignores it in my test).

http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html#constructor-property

Following the old documentation leads to this exception:

    bucket-property

  3. Enter the following policy, replace bucket_name with your bucket name:

    bucket-policy-editor

    {
        "Version": "2012-10-17",
        "Statement": [
            {
                "Effect": "Allow",
                "Principal": "*",
                "Action": "s3:GetObject",
                "Resource": "arn:aws:s3:::bucket_name/uploads/*"
            }
        ]
    }
    
  4. Go to IAM console and create a new IAM user. Remember your user credentials(key/access token)

  5. Enter user page, select Permission tab, look at Inline Policies section, and click Create User Policy

    iam-user

  6. Select Custom Policy

    custom-policy

  7. Enter the following policy, replace bucket_name with your bucket name:

    review-policy

    {
        "Version": "2012-10-17",
        "Statement": [
            {
                "Effect": "Allow",
                "Action": [
                    "s3:*"
                ],
                "Resource": [
                    "arn:aws:s3:::bucket_name/uploads/*"
                ]
            }
        ]
    }
    
  8. Edit config.json and set following keys:

    {
        "production": {
            ...
            "imageUploadType": "s3",
            "s3": {
                "accessKeyId": "YOUR_S3_ACCESS_KEY_ID",
                "secretAccessKey": "YOUR_S3_ACCESS_KEY",
                "region": "YOUR_S3_REGION" // example: ap-northeast-1
            },
            "s3bucket": "YOUR_S3_BUCKET_NAME"
        }
    }
    
  9. In additional to edit config.json directly, you could also try environment variable.
