Overview
This node operation checks if a specified bucket exists in the MinIO storage service. It is useful for workflows that need to verify the presence of a bucket before performing further actions such as uploading or managing files. For example, before uploading files, a workflow can use this operation to ensure the target bucket exists to avoid errors.
Use Case Examples
- Check if a bucket named 'my-bucket' exists before uploading files.
- Verify bucket existence as a conditional step in a data backup workflow.
Properties
| Name | Meaning |
|---|---|
| Bucket Name | The name of the bucket to check for existence. It can be selected from a list of existing buckets or provided directly by ID. |
Output
JSON
exists- Boolean indicating whether the specified bucket exists (true) or not (false).
Dependencies
- Requires connection to a MinIO storage service with appropriate credentials to access bucket information.
Troubleshooting
- If the node returns an error indicating the bucket cannot be found, verify that the bucket name is correct and that the credentials have permission to list or access buckets.
- Connection errors may occur if the MinIO service endpoint or credentials are misconfigured; ensure the API authentication token or key is valid and the service is reachable.
