# Nodes configuration
# This configuration makes the gateway use the first node (grpc://s01.neofs.devenv:8080)
# while it's healthy. Otherwise, gateway uses the second node (grpc://s01.neofs.devenv:8080)
# for 10% of requests and the third node (grpc://s03.neofs.devenv:8080) for 90% of requests.
# Until nodes with the same priority level are healthy
# nodes with other priority are not used.
# The lower the value, the higher the priority.

# Default policy of placing containers in NeoFS
# If a user sends a request `CreateBucket` and doesn't define policy for placing of a container in NeoFS, the S3 Gateway
# will put the container with default policy. It can be specified via environment variable, e.g.:
default_policy: REP 3

# CORS
# value of Access-Control-Max-Age header if this value is not set in a rule. Has an int type.
