strapi-provider-upload-s3-saycustom

*Added isPublic and baseUrl options on top of the existing configurations. *Added one more option - ACL to pass exact ACL access as a string. Please check here for the list of access possible with ACL. Possible values are : private, public-read, public-read-write, aws-exec-read, authenticated-read, bucket-owner-read, bucket-owner-full-control & log-delivery-write *if #####isPublic is true, ACL will be set to ######public-read and by default its false it will be ######private. *if both #####isPublic and ACL mentioned priority will be for ACL and if incorrect ACL added, it depends on how AWS throws error. *Added #####isBaseUrlHttps for deciding if the URL is https, by default its http

i have used the below code,

\app\config\plugins.js (as per strapi documentation)

module.exports = ({ env }) => ({
    upload: {
        provider: 's3-saycustom',
        providerOptions: {
            accessKeyId: env('AWS_ACCESS_KEY_ID'),
            secretAccessKey: env('AWS_ACCESS_SECRET'),
            region: env('AWS_REGION'),
            baseUrl: env('STATIC_DOMAIN_NAME'),
            isBaseUrlHttps: env('IS_HTTPS_ENABLED_FOR_DOMAIN'),
            params: {
                Bucket: env('AWS_BUCKET_NAME'),
            },
            isPublic: env('AWS_IS_PUBLIC'),
            ACL: env('AWS_ACL'),
            baseFolder: env('AWS_URL_FOLDER')
        },
    },
});

.env file

AWS_ACCESS_KEY_ID='YOUR AWS ACCESS KEY'
AWS_ACCESS_SECRET='YORU AWS ACCESS SECRET'
AWS_REGION='us-east-1' //add your region
AWS_BUCKET_NAME='ADD YOUR BUCKET NAME'
STATIC_DOMAIN_NAME='addyourdomain.com'//Add your domain or CDN, if this is not set it will use AWS S3 url by default.
//AWS_IS_PUBLIC=true //add this to true if you want to make your file publicly available. //commented this in my code as am using ACL option and priority will be for the ACL option.
AWS_ACL= 'public-read' //if you are totally clueless and not sure how to set this then use AWS_IS_PUBLIC to true dont worry about anything else.
IS_HTTPS_ENABLED_FOR_DOMAIN=true //if you want to enable https, by default its http so this is an optional field
AWS_URL_FOLDER = 'asset' //naming folder or add this in url for ALB redirection, optional parameter

Few tips to note when you are implementing this,

Bucket has to be public, if dont want the bucket to be public create custom controller to access the image via URL and add the code. Refer asset.js file in repo for details.
Added bucket policy to not to make it directly accessible, added AWS OAI policy.

{
    "Version": "2008-10-17",
    "Id": "PolicyForCloudFrontPrivateContent",
    "Statement": [
        {
            "Sid": "1",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::cloudfront:user/CloudFront Origin Access Identity XXXXXXXXX"
            },
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::BUCKETNAME/*"
        }
    ]
}

Created CDN in AWS for better performance.
We can also create custom domain in R53 or outside domain provider using CNAME entry and map into S3 endpoint.
