kubernetes - 使用 Redis 处理程序在 Istio 中进行速率限制

Question

我正在尝试使用 Redis Handler ISTIO 使用 Redis 处理程序应用 ISTIO 速率限制
但是混合器无法找到 redis 处理程序。以下来自混音器日志:

2019-05-27T11:59:23.910183Z warn Unable to find a handler for action. rule[action]='quota.rule.istio-system[0]', handler='redishandler.istio-system'

• redisquota: could not create a connection to redis server: NOAUTH Authentication required.''. Also, how to provide Redis credential for the template?

Answer 1

redis 配额不支持 Authentication

    // test redis connection
    option := redis.Options{
        Addr: b.adapterConfig.RedisServerUrl,
    }

    if b.adapterConfig.ConnectionPoolSize > 0 {
        option.PoolSize = int(b.adapterConfig.ConnectionPoolSize)
    }
