MinIO S3 in Alpine with instance-IAM-role credentials
# Using AWS instance IAM role to provide credentials to minio-client cli.
# Works in Alpine 3.18+ (the minio-client package is not available in 3.17)
# Should also work anywhere else minio, curl, and jq can run.
# Provides a very-lightweight way to access S3 from Alpine
apk add minio-client curl jq
