Apache Flink | openEuler

Current Apache Flink docker images are built on the openEuler. This repository is free to use and exempted from per-user rate limits.

Apache Flink is a framework and distributed processing engine for stateful computations over unbounded and bounded data streams. Flink has been designed to run in all common cluster environments, perform computations at in-memory speed and at any scale.

Usage

In this usage, users can select the corresponding {Tag} based on their requirements.

• Starting a Session Cluster on Docker:

  A Flink Session cluster can be used to run multiple jobs. Each job needs to be submitted to the cluster after the cluster has been deployed. To deploy a Flink Session cluster with Docker, you need to start a JobManager container. To enable communication between the containers, we first set a required Flink configuration property and create a network:

  $ FLINK_PROPERTIES="jobmanager.rpc.address: jobmanager"
  $ docker network create flink-network
  

  Then we launch the JobManager:

  $ docker run \
      --rm \
      --name=jobmanager \
      --network flink-network \
      --publish 8081:8081 \
      --env FLINK_PROPERTIES="${FLINK_PROPERTIES}" \
      openeuler/flink:{Tag} jobmanager
  

  and one or more TaskManager containers:

  $ docker run \
      --rm \
      --name=taskmanager \
      --network flink-network \
      --env FLINK_PROPERTIES="${FLINK_PROPERTIES}" \
      openeuler/flink:{Tag} taskmanager
  

  The web interface is now available at localhost:8081.
