# Amazon S3

The `robomotion amazons3` CLI connects to Amazon S3 for object storage operations. It uploads, downloads, lists, copies, and deletes objects; manages buckets; generates presigned URLs; and handles file operations across S3 buckets.

## When to use
- Upload or download files between local filesystem and S3
- List, copy, or delete objects in S3 buckets
- Create or manage S3 buckets
- Generate presigned URLs for temporary access

## Prerequisites
- `robomotion` CLI installed
- Package installed: `robomotion install amazons3`
- AWS access key and secret key configured via Robomotion vault

## IMPORTANT: Session Mode Required for Multi-Step Operations
Each CLI command runs as a **separate process** — connection IDs from `connect` do NOT persist across calls.
You MUST use `--session` on `connect` and pass `--session-id` to all subsequent commands.

## Workflow
1. Install (once): `robomotion install amazons3`
2. Connect with session:
   ```
   robomotion amazons3 connect --session --output json
   # → {"outClientId":"<client-id>","session_id":"<session-id>"}
   ```
3. Use the returned `client-id` and `session-id` in all subsequent commands:
   ```
   robomotion amazons3 upload_file --client-id "<client-id>" --bucket <bucket> --key <key> --file-path <file> --session-id "<session-id>" --output json
   ```
4. Disconnect when done:
   ```
   robomotion amazons3 disconnect --client-id "<client-id>" --session-id "<session-id>" --output json
   ```

**Always** append `--output json` to get structured JSON results.
