S3 Deployment Skill

Instructions

This skill handles uploading a local directory (e.g., generated slides) to an AWS S3 bucket or any S3-compatible object storage (e.g., MinIO, Aliyun OSS, Tencent COS) for static website hosting.

Prerequisites:
- Ensure the user has valid credentials in their environment:
  - S3_ACCESS_KEY_ID
  - S3_SECRET_ACCESS_KEY
  - S3_BUCKET (Optional if provided as an argument)
  - S3_REGION (Optional)
  - S3_ENDPOINT_URL (Required for non-AWS services like MinIO or Aliyun OSS)
  - S3_CUSTOM_DOMAIN (Optional, overrides the generated URL)
- Ensure boto3 is installed in the environment. If not, install it.
- Identify the source directory (e.g., slides/<ppt-name>/dist/) and the target S3 bucket name.
Implementation:
- Create a Python script using boto3 to walk through the source directory.
- Configure the S3 client with endpoint_url if provided, to support S3-compatible providers.
- Upload each file, maintaining the relative path structure.
- Crucial: specific ContentType must be set for each file based on its extension (e.g., text/html for .html, text/css for .css, image/png for .png) so that the browser renders it correctly.
- Make the objects public if the bucket policy allows or requires ACL (optional, based on bucket configuration).
- Print the final website URL.

Usage

Use the bundled script to upload files:

# Explicit bucket name
uv run {baseDir}/scripts/upload_to_s3.py "slides/my-presentation/dist" "my-bucket" --prefix "presentations/my-presentation"

# Using S3_BUCKET from environment
uv run {baseDir}/scripts/upload_to_s3.py "slides/my-presentation/dist" --prefix "presentations/my-presentation"

Usage Guidelines

Bucket Name: Check if S3_BUCKET is set in environment. If not, ask the user for the S3 Bucket name.
Endpoint URL: Check if the user is using a non-AWS provider (like MinIO or Aliyun). If so, request or verify the endpoint_url.
Source Path: Default to looking for dist folders in slides/ if not specified.
