Flink 1.12 Native Kubernetes 演进 - Flink 1.10Flink 1.10 开始支持将 Native Kubernetes 作为其资源管理器。在该版本中，你可以使用以下命令在你的 Kubernetes 集群中创建一个 flink session。 ./bin/kubernetes-sess. Volcano. Kubernetes has rapidly established itself as the de facto standard for orchestrating containerized infrastructures. Flink Streaming comes with a built-in TwitterSource class for establishing a connection to this stream. flink 在 kubernetes 上的 部署 和原生 kubernetes 上的 部署 有什么不同？ kubernetes apache-flink flink-streaming Flink 5lwkijsr 10个月前 预览 (193) 10个月前 千呼万唤始出来，在 Kubernetes 如火如荼的今天，Flink 社区终于在 1.10 版本提供了对 Kubernetes 的原生支持，也就是 Native Kubernetes Integration 。. 下图描述了flink如何与kubernetes集成： 创建Flink Kubernetes Session集群时，Flink客户端将首先连接到Kubernetes ApiServer提交集群描述，包括ConfigMap规范，Job Manager服务规范，Job Manager Deployment规范和Owner Reference。然后，Kubernetes将创建JobManager Deployment . With the Pulsar Operator, Pulsar can run seamlessly in the Kubernetes clusters deployed on a public or private cloud. 结合官方给出的提交和部署流程图就更清晰了：kubernetes上部署了Flink Master，由Flink Client来提交session cluster和job的请求： Flink Kubernetes和Flink Native Kubernetes的区别. The flink-conf.yaml, log4j.properties, logback.xml in this path will be overwritten from config map. 2020 年 2 月 11 日，社区发布了 Flink 1.10.0 版本，该版本对性能和稳定性做了很大的提升，同时引入了 native Kubernetes 的特性。对于 Flink 的下一个稳定版本，社区在 2020 年 4 月底冻结新特性的合入，预计在 2020 年 5 月中旬会推出 Flink 1.11，在新版本中将重点引入新 . flink支持多种部署模式，比如standalone、sesson、per job、application，一般在生产环境我们都是将flink程序部署到k8s或者yarn等资源管理器上。. Flink followed up with 27 percent. The latest version of Apache Flink, v1.10.0, has arrived. Native模式下高可用.
