CLI command

Create the file bucket-policy.json with the following content:

{
    "Version": "2023-04-17",
    "Id": "MyBucketPolicy",
    "Statement": [
        {
            "Sid": "DelegateAccess",
            "Effect": "Allow",
            "Principal": {
                "SCW": "application_id:<APPLICATION_ID>"
            },
            "Action": [
                "s3:ListBucket",
                "s3:GetObject"
            ],
            "Resource": [
                "<BUCKET_NAME>",
                "<BUCKET_NAME>/*"
            ]
        }
    ]
}

Then, run the command:

aws s3api put-bucket-policy --bucket <BUCKET_NAME> --policy file://bucket-policy.json

PutBucketWebsite

This operation enables the bucket website feature and sets the basic configuration for the website.

PUT /my-bucket?website HTTP/1.1
{
    "IndexDocument" : {
        "Suffix": "index.html"
    },
    "ErrorDocument": {
        "Key": "error.html"
    }
}

To enable the bucket website feature via the CLI, you can create a file called bucket-website.json with the index and error page names.

{
    "IndexDocument" : {
        "Suffix": "index.html"
    },
    "ErrorDocument": {
        "Key": "error.html"
    }
}

Then, upload it using the following command:

aws s3api put-bucket-website --bucket <BUCKET_NAME> --website-configuration file://bucket-website.json
