# Generates s3cmd config from rook.io CephObjectStoreUser secrets fetched from
# Kubernetes apiserver. Accepts extra K8S_INTERNAL=1 environment variable flag
# that generates config that connects to internal rgw service.
#
# Usage:
#   bazel run //cluster/tools:rook-s3cmd-config > config
#   s3cmd -c config --region "STORENAME:default-placement" mb s3://test/
