MinIO S3 in Alpine with instance-IAM-role credentials
Raw
minio-client.sh
# 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
