Upgrade Guide

There are several changes in the configuration files and API.

1. Add environment tag in server.yml and default is disabled.

# environment tag that will be registered on consul to support multiple instances per env for testing.
# https://github.com/networknt/light-doc/blob/master/docs/content/design/env-segregation.md
# This tag should only be set for testing env, not production. The production certification process will enforce it.
# environment: test1

1. Add consulToken in secret.yml

# Consul service registry and discovery and default is disable.

# Consul Token for service registry and discovery
# consulToken: the_one_ring

    /**

     * the result is has been gone through the load balance with request key
     *
     * requestKey is used to control the behavior of load balance except
     * round robin and local first which this value is null. For consistent hash
     * load balance, normally client_id or user_id from JWT token should be passed
     * in to route the same client to the same server all the time or the same user
