upstream-seaweedfs/test/s3/proxy_signature/test.sh

#!/usr/bin/env bash
#
# Integration test for S3 signature verification behind a reverse proxy.
#
# Usage:
#   # With aws CLI installed locally:
#   docker compose up -d --build && ./test.sh && docker compose down
#
#   # Without aws CLI (runs test inside a container):
#   docker compose up -d --build
#   docker run --rm --network host --entrypoint "" amazon/aws-cli:latest \
#       bash < test.sh
#   docker compose down
#
# This script tests S3 operations through an nginx reverse proxy to verify
# that signature verification works correctly when SeaweedFS is configured
# with -s3.externalUrl=http://localhost:9000.
