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

	export MC_HOST_s3=$(curl -s http://169.254.169.254/latest/meta-data/iam/security-credentials/$(curl -s http://169.254.169.254/latest/meta-data/iam/security-credentials/ \| head -1) \| jq -r '"https://\(.AccessKeyId):\(.SecretAccessKey):\(.Token)@s3.amazonaws.com"')

	mcli ls s3/mybucket
