简介​

KnowStreaming 是一套云原生的Kafka管控平台，脱胎于众多互联网内部多年的Kafka运营实践经验，专注于Kafka运维管控、监控告警、资源治理、多活容灾等核心场景。在用户体验、监控、运维管控上进行了平台化、可视化、智能化的建设，提供一系列特色的功能，极大地方便了用户和运维人员的日常使用，让普通运维人员都能成为Kafka专家。

快速部署 KnowStreaming​

首先根据快速安装文档部署 Rainbond

KnowStreaming 已发布至 开源应用商店 ，用户可搜索 KnowStreaming，一键安装 KnowStreaming

安装后，访问 KnowStreaming-UI 进入控制台，默认密码：admin / admin

快速部署 Kafka 集群​

上面我们已经部署了 KnowStreaming，接下来我们也可通过 开源应用商店 安装Kafka集群并进行对接。

Kafka 已发布至 开源应用商店 ，用户可搜索 kafka，一键安装 Kafka-Zookeeper-Bitnami

安装完成后，我们进入 kafka1 和 kafka2 的组件 -> 环境变量

修改 KAFKA_CFG_ADVERTISED_LISTENERS 环境变量为组件9092端口的对外IP + 端口，例如：PLAINTEXT://192.168.3.162:10000

修改 JMX_PORT 环境变量为TCP对外端口地址供 Logikm 获取指标。例如：JMX_PORT为9999，组件对应的端口也要为9999，同时tcp对外端口也是9999

使用 KnowStreaming 对接并管理 Kafka 集群​

接下来我们通过 KnowStreaming 对接刚刚安装的 kafka集群。

访问 KnowStreaming，接入集群，根据页面提示填写对应信息。

对接完成后，我们就可通过 KnowStreaming 管理 kafka 集群啦。

:::info Rainbond is a product that has been committed to opening up the entire process of enterprise application delivery. An indispensable part of this process is the continuous upgrading and iteration of enterprise applications.The unique ability of Rainbond is to package enterprise application systems including multiple service components, and perform one-click installation, upgrade and rollback operations.The above only solves the versioning problem of the application itself.To fully automate the upgrade iteration process of enterprise applications, it is also necessary to automatically handle the version control of the database table structure (Schema).After continuous exploration, Rainbond first integrated the ability of database schema version management in the cloud native era with the industry-leading Liquibase in the field of source code construction. :::

Locust is an easy-to-use, scriptable and extensible performance testing tool.And there is a user-friendly web interface that displays test progress in real time.The load can even be changed while the test is running.It can also run without UI, making it easy to use for CI/CD testing.

Locust makes it easy to run load tests that are distributed across multiple machines.Locust is based on events (gevent), so it can support thousands of concurrent users on a single computer.In contrast to many other event-based applications, it does not use callbacks.Instead, it uses lightweight processes via gevent.Each Locust (locust) concurrently accessing the site is actually running in its own process (Greenlet).This allows users to write very expressive scenarios in Python without having to use callbacks or other mechanisms. :::

There are many existing ServiceMesh frameworks, such as Istio, linkerd, etc.For users, in the test environment, the effect that needs to be achieved is fast and out-of-the-box.However, in the production environment, there may be requirements such as fusing and delay injection.Then a single ServiceMesh framework cannot meet the different needs of users at the same time.

In previous Rainbond versions, Rainbond supported a variety of different application governance modes. As an application-level plug-in, it implemented the switching of Istio governance modes.

This article will analyze the principle of Rainbond's implementation of the Istio governance model. :::

:::info Rainbond , as a cloud native application management platform, is born with a distributed gateway rbd-gateway that guides north-south network traffic.Different from the general Ingress configuration, users need to define their own domain name experience. Rainbond's gateway policy can automatically generate a domain name access policy with one click, and users can immediately access the business system deployed on Rainbond through this domain name.This user experience is very friendly in development and testing scenarios. This article explains in detail how this mechanism is implemented. :::

Two years ago, Service Mesh (Service Mesh) became popular as soon as it came out. Many people think it is the final form of microservice architecture, because it can decouple business code from microservice architecture, that is, business The code does not need to be modified to implement the microservice architecture, but the decoupling is not thorough enough, and it is still inconvenient to use. Although the architecture is decoupled, the deployment has not been decoupled.
  • It is impossible to choose a suitable Service Mesh framework according to different environments or customer needs.
  • It is impossible to learn and use Service Mesh in the development environment, and enable the production environment on demand. :::

Rainbond is an integrated cloud-native application management platform. It provides an "application-centric" abstraction. Users do not need to learn K8s and containers. The platform encapsulates K8s and containers inside. It greatly improves the ease of use and the convenience of installation, but how to replace the internal components of the package is a problem. This article will explain how to use Harbor to replace the original default mirror warehouse of Rainbond.
