Can I automatically share files from Object Storage publicly<\/strong>?
<\/strong><\/h4>\n

Yes this is possible with the S3 API<\/strong>, you can find the steps on how to set this up below. <\/p>\n


<\/p>\n

How do <\/strong>I automatically share files from Object Storage publicly<\/strong>?<\/strong><\/h4>\n
    \n
  1. Setup <\/strong>your S3 tool. The easiest way is to use aws cli<\/a><\/u>. Please make sure to have it installed and configured properly. <\/li>\n
  2. Create a file public-sharing-policy.json with the following content:
    {
    “Id”: “your-fancy-name”,
    “Version”: “2012-10-17”,
    “Statement”: [
    {
    “Action”: [
    “s3:GetObject”
    ],
    “Effect”: “Allow”,
    “Resource”: [
    “arn:aws:s3:::foldername\/file”
    ],
    “Principal”: “*”
    }
    ]
    }
    <\/strong><\/li>\n
  3. Next you need to enable public Sharing for a folder an all its sub items. To do this Create a file public-sharing-policy.json with following content:

    \n
    {
     \"Id\": \"your-fancy-name\",
     \"Version\": \"2012-10-17\",
     \"Statement\": [
     {
     \"Action\": [
     \"s3:GetObject\"
     ],
     \"Effect\": \"Allow\",
     \"Resource\": [
     \"arn:aws:s3:::foldername\/*\"
     ],
     \"Principal\": \"*\"
     }
     ]
    }<\/code><\/pre>\n<\/li>\n
  4. Please be aware that the S3 Object Storage doesn’t support file listing in browser. The s3TenantId can be retrieved via the Contabo API<\/u><\/a><\/u>.

    The only difference is that you use “*”as a wildcard \/ placeholder for the file name. Of course you can have constructs like “arn:aws:s3:::foldername1\/foldername2\/*”.<\/li>\n<\/ol>\n
    How do I disable public sharing via the S3 API?<\/strong><\/h4>\n
    To disable the Public Sharing for a file or folder you need first to get the current policy via:<\/p>\n

    <\/p>\n
    aws --profile eu2 --endpoint-url https:\/\/eu2.contabostorage.com s3api get-bucket-policy --bucket foo<\/pre>\n
    Then remove the parts you would like to remove and do the put-bucket-policy again with the modified file. If it is the last entry in there you could also delete it completely via:

    <\/p>\n
    aws --profile eu2 --endpoint-url https:\/\/eu2.contabostorage.com s3api delete-bucket-policy --bucket foo<\/code><\/pre>\n
    But be cautious as this will delete all policies on that bucket.<\/p>\n<\/p>\n
