Connecting Selectel

This guide walks you through connecting a Selectel Object Storage destination to Pluton.

Prerequisites​

Before connecting Selectel, you need:

  1. A Selectel account - Sign up here
  2. An S3-compatible Access Key ID and Secret Access Key

Getting Your Selectel Credentials​

Step 1: Create S3 Keys​

  1. Log into the Selectel Control Panel
  2. Navigate to Object Storage in the left sidebar
  3. Go to the S3 Keys section
  4. Click Create Key
  5. Copy the Access Key ID and Secret Access Key
  6. Important: Save both credentials immediately - the Secret Access Key is shown only once

Step 2: Create a Container​

  1. In the Object Storage section, click Create Container
  2. Enter a name for your container (bucket)
  3. Select your preferred region and storage type
  4. Configure access settings and create the container

Connecting to Pluton​

Pluton Selectel

Step 1: Add Storage​

  1. In Pluton, navigate to Storages
  2. Click Add Storage button
  3. Select Selectel from the provider list

Step 2: Configure Connection​

Fill in the required fields:

  • Storage Name: A friendly name (e.g., "Selectel Backups")
  • Access Key ID: Paste your Selectel S3 Access Key ID
  • Secret Access Key: Paste your Selectel S3 Secret Access Key

Step 3: Advanced Options (Optional)​

Additional settings available:

  • Server-side Encryption: Choose AES256 or KMS encryption for data at rest
  • Storage Class: Select the storage class for new objects
  • Bucket ACL: Set access control for bucket operations
  • Upload Cutoff: Threshold for switching to chunked uploads (default: 200 MiB)
  • Chunk Size: Size of chunks for multipart uploads (default: 5 MiB)
  • Force Path Style: Enabled by default; use path-style access for S3 requests
  • V2 Authentication: Enable if your setup requires v2 auth signatures

Step 4: Test and Save​

  1. Click Test Connection to verify credentials
  2. If successful, click Save
  3. Your Selectel storage is now ready for backup plans

Common Issues​

Authentication Failure: Verify your S3 Access Key ID and Secret Access Key are correct. Ensure the key has not been revoked in the Selectel control panel.

Container Not Found: Confirm the container (bucket) name is correct and that it exists in your Selectel account.

Permission Denied: Check that your S3 credentials have read and write permissions on the target container.

Best Practices​

  • Create dedicated S3 keys for Pluton with minimum required permissions
  • Use Selectel's storage classes to optimize cost for backup data
  • Monitor storage usage through the Selectel control panel
  • Enable server-side encryption for sensitive backup data
