[FEATURE] Feature Request: Elastic Cloud ID Authentication Support

[Blankll]

Summary

Add support for Elastic Cloud ID authentication to simplify connections to Elastic Cloud hosted clusters.

Background

Currently, DocKit supports Elasticsearch connections via:

• Direct host URL with username/password (Basic Auth)
• API Key authentication

Elastic Cloud provides a Cloud ID — a base64-encoded string containing the cluster endpoint, region, and deployment configuration. Supporting Cloud ID would streamline the connection process for Elastic Cloud users.

Proposed Feature

Connection Method

Add a "Cloud ID" connection option alongside existing authentication methods:

Connection Type: Elastic Cloud
Cloud ID: production:dXMtZWFzdC0xLmF3cy5mb3VuZC5pbyQ...
Username: elastic
Password: ••••••••

or with API Key:

Connection Type: Elastic Cloud
Cloud ID: production:dXMtZWFzdC0xLmF3cy5mb3VuZC5pbyQ...
API Key: VnVhQ2ZHY0JDZGJrU...

Technical Implementation

1. Cloud ID Parser: Decode the base64 Cloud ID to extract:

   • Elasticsearch endpoint URL
   • Kibana endpoint (optional)
   • Region information

2. UI Changes:

   • Add "Cloud ID" field in connection form
   • Auto-detect and pre-fill when Cloud ID is provided
   • Optionally hide the host URL field when using Cloud ID

3. Validation:

   • Validate Cloud ID format before attempting connection
   • Provide clear error messages for invalid Cloud IDs

User Benefits

• Simplified Setup: Copy-paste Cloud ID from Elastic Cloud console
• Fewer Errors: No need to manually type long host URLs
• Better UX: Aligns with Elastic Cloud's recommended connection method
• Consistency: Matches how official Elastic clients handle Cloud connections

Reference

• Elastic Cloud ID Format
• Elasticsearch JavaScript Client Cloud ID Support

Priority

Medium - Nice to have for Elastic Cloud users, but direct URL connections still work

Additional Notes

• Consider making this available for both Elasticsearch and OpenSearch (if OpenSearch Cloud IDs have similar format)
• Should maintain backward compatibility with existing connection profiles
• May want to add a "Test Connection" button to validate before saving
