This will open the login page of Casdoor, upon successful login, STS credentials along with any buckets discovered using the credentials will be printed on the screen, for example:

```
{
  buckets: [ ],
  credentials: {
    AccessKeyID: "EJOLVY3K3G4BF37YD1A0",
    SecretAccessKey: "1b+w8LlDqMQOquKxIlZ2ggP+bgE51iwNG7SUVPJJ",

        val buckets =
            splitBucketsByScenarios(
                scenarios,
                testProjectToScenarioDurations,
                testProjectScenarioDurationsFallback,
                performanceTestCoverage.numberOfBuckets,
            )
        return buckets.mapIndexed { bucketIndex: Int, bucket: PerformanceTestBucket ->

and then click "Grant access"

On the browser now you shall see the list of buckets output, along with your temporary credentials obtained from MinIO.

## Features

- A pool in decommission still allows READ access to all its contents, newer WRITEs will automatically be scheduled to only pools not in decommission status.
- All versioned buckets maintain the same order for "versions" for each object after being decommissioned to the other pools.
- A pool interrupted during the decommission process, such as for a cluster restart, resumes from where it left off.
