This testcase is to provide a reproducable testcase showing the implementation of s3 at IONOS does not work as expected. This same testcase works on other providers, we tested against AWS and our own WX-ONE.
create a file .ionosrc with the following content (adjust to your settings)
{
"s3": {
"bucket": "your bucket",
"endPoint": "s3.eu-central-3.ionoscloud.com",
"region": "eu-central-3",
"port": 443,
"useSSL": true,
"accessKey": "your accesskey",
"secretKey": "your secretkey"
}
}
