Gateway Service Configuration

Introduction

The Infinite Scale Gateway service is responsible for passing requests to the storage providers. Other services never talk to storage providers directly but will always send their requests via this service.

Default Values

  • Gateway listens on port 9142 by default.

Caching

The gateway service can use a configured store via the global OCIS_CACHE_STORE environment variable.

Note that for each global environment variable, a service-based one might be available additionally. For precedences see Environment Variable Notes. Check the configuration section below. Supported stores are:



Store Type Description

memory

Basic in-memory store and the default.

redis-sentinel

Stores data in a configured Redis Sentinel cluster.

nats-js-kv

Stores data using key-value-store feature of NATS JetStream.

noop

Stores nothing. Useful for testing. Not recommended in production environments.

ocmem

(deprecated) Advanced in-memory store allowing max size.

redis

(deprecated) Stores data in a configured Redis cluster.

etcd

(deprecated) Stores data in a configured etcd cluster.

nats-js

(deprecated) Stores data using the key-value-store feature of NATS JetStream.

Other store types may work but are currently not supported.

The gateway service can only be scaled if not using the memory store and the stores are configured identically over all instances!
If you have used one of the deprecated stores of a former version, you should reconfigure to use one of the supported ones as the deprecated stores will be removed in a later version.
Store specific notes

  • When using redis-sentinel:
    The Redis master to use is configured via e.g. OCIS_CACHE_STORE_NODES in the form of <sentinel-host>:<sentinel-port>/<redis-master> like 10.10.0.200:26379/mymaster.

  • When using nats-js-kv:

    • It is recommended to set OCIS_CACHE_STORE_NODES to the same value as OCIS_EVENTS_ENDPOINT. That way the cache uses the same nats instance as the event bus.

    • Authentication can be added, if configured, via OCIS_CACHE_AUTH_USERNAME and OCIS_CACHE_AUTH_PASSWORD.

    • It is possible to set OCIS_CACHE_DISABLE_PERSISTENCE to instruct nats to not persist cache data on disc.

Configuration

Environment Variables

The gateway service is configured via the following environment variables. Read the Environment Variable Types documentation for important details.

OCIS_GRPC_CLIENT_TLS_MODE

string

TLS mode for grpc connection to the go-micro based grpc services. Possible values are 'off', 'insecure' and 'on'. 'off': disables transport security for the clients. 'insecure' allows using transport security, but disables certificate verification (to be used with the autogenerated self-signed certificates). 'on' enables transport security, including server certificate verification.
