The Apache Software Foundation (ASF) Flink development team has released version 1.0.0 of the Apache Flink Kubernetes Operator. Only around two months after the first preview, the first production-ready major release of the operator is now available, with which developers can manage their Flink clusters on Kubernetes.
Integrated into the cloud-native tooling for Kubernetes, the operator provides all the important functions for the automated management of Flink deployments – from applications to sessions to Flink jobs. The preview already provided, monitor, update, stop or delete deployments, and the production-ready major release will add further functions for restoring and session job management. While FlinkDeployment is limited to managing application and session clusters, developers with FlinkSessionJob now also have direct access to their Flink jobs in a running session.
With version 1.0.0 of the Apache Flink Kubernetes Operator, the development team is also providing a new API v1beta1 – and in the announcement explicitly points out that the presumed beta version has nevertheless been tested and released for use in production environments. Detailed information is available for help with upgrading to the new versions.
The announcement article summarizes further details about the innovations in the major release. The Apache Flink Kubernetes Operator version 1.0.0 is now available for download and can be used with Flink versions 1.13, 1.14 and 1.15 (recommended).
