版本：2.3.8

Set Up with Kubernetes

This section provides a quick guide to use SeaTunnel with Kubernetes.

Prerequisites

We assume that you have one local installation as follow:

So that the kubectl and helm commands are available on your local system.

Take kubernetes minikube as an example, you can start a cluster with the following command:

minikube start --kubernetes-version=v1.23.3

Installation

SeaTunnel Docker Image

To run the image with SeaTunnel, first create a Dockerfile:

Flink
Zeta (local-mode)
Zeta (cluster-mode)

FROM flink:1.13

ENV SEATUNNEL_VERSION="2.3.8"
ENV SEATUNNEL_HOME="/opt/seatunnel"

RUN wget https://dlcdn.apache.org/seatunnel/${SEATUNNEL_VERSION}/apache-seatunnel-${SEATUNNEL_VERSION}-bin.tar.gz
RUN tar -xzvf apache-seatunnel-${SEATUNNEL_VERSION}-bin.tar.gz
RUN mv apache-seatunnel-${SEATUNNEL_VERSION} ${SEATUNNEL_HOME}

RUN cd ${SEATUNNEL_HOME} && sh bin/install-plugin.sh ${SEATUNNEL_VERSION}

Then run the following commands to build the image:

docker build -t seatunnel:2.3.8-flink-1.13 -f Dockerfile .

Image seatunnel:2.3.8-flink-1.13 needs to be present in the host (minikube) so that the deployment can take place.

Load image to minikube via:

minikube image load seatunnel:2.3.8-flink-1.13

FROM openjdk:8

ENV SEATUNNEL_VERSION="2.3.8"
ENV SEATUNNEL_HOME="/opt/seatunnel"

RUN wget https://dlcdn.apache.org/seatunnel/${SEATUNNEL_VERSION}/apache-seatunnel-${SEATUNNEL_VERSION}-bin.tar.gz
RUN tar -xzvf apache-seatunnel-${SEATUNNEL_VERSION}-bin.tar.gz
RUN mv apache-seatunnel-${SEATUNNEL_VERSION} ${SEATUNNEL_HOME}

RUN cd ${SEATUNNEL_HOME} && sh bin/install-plugin.sh ${SEATUNNEL_VERSION}

Then run the following commands to build the image:

docker build -t seatunnel:2.3.8 -f Dockerfile .

Image seatunnel:2.3.8 need to be present in the host (minikube) so that the deployment can take place.

Load image to minikube via:

minikube image load seatunnel:2.3.8

FROM openjdk:8

ENV SEATUNNEL_VERSION="2.3.8"
ENV SEATUNNEL_HOME="/opt/seatunnel"

RUN wget https://dlcdn.apache.org/seatunnel/${SEATUNNEL_VERSION}/apache-seatunnel-${SEATUNNEL_VERSION}-bin.tar.gz
RUN tar -xzvf apache-seatunnel-${SEATUNNEL_VERSION}-bin.tar.gz
RUN mv apache-seatunnel-${SEATUNNEL_VERSION} ${SEATUNNEL_HOME}
RUN mkdir -p $SEATUNNEL_HOME/logs
RUN cd ${SEATUNNEL_HOME} && sh bin/install-plugin.sh ${SEATUNNEL_VERSION}

Then run the following commands to build the image:

docker build -t seatunnel:2.3.8 -f Dockerfile .

Image seatunnel:2.3.8 needs to be present in the host (minikube) so that the deployment can take place.

Load image to minikube via:

minikube image load seatunnel:2.3.8

Deploying The Operator

Flink
Zeta (local-mode)
Zeta (cluster-mode)

The steps below provide a quick walk-through on setting up the Flink Kubernetes Operator. You can refer to Flink Kubernetes Operator - Quick Start for more details.

Notice: All the Kubernetes resources bellow are created in default namespace.

Install the certificate manager on your Kubernetes cluster to enable adding the webhook component (only needed once per Kubernetes cluster):

kubectl create -f https://github.com/jetstack/cert-manager/releases/download/v1.8.2/cert-manager.yaml

Now you can deploy the latest stable Flink Kubernetes Operator version using the included Helm chart:

helm repo add flink-operator-repo https://downloads.apache.org/flink/flink-kubernetes-operator-1.3.1/

helm install flink-kubernetes-operator flink-operator-repo/flink-kubernetes-operator \
--set image.repository=apache/flink-kubernetes-operator

You may verify your installation via kubectl:

kubectl get pods
NAME                                                   READY   STATUS    RESTARTS      AGE
flink-kubernetes-operator-5f466b8549-mgchb             1/1     Running   3 (23h ago)   16d

none

Run SeaTunnel Application

Run Application:: SeaTunnel already providers out-of-the-box configurations.

Flink
Zeta (local-mode)
Zeta (cluster-mode)

In this guide we will use seatunnel.streaming.conf:

env {
  parallelism = 1
  job.mode = "STREAMING"
  checkpoint.interval = 2000
}

source {
    FakeSource {
      result_table_name = "fake"
      row.num = 160000
      schema = {
        fields {
          name = "string"
          age = "int"
        }
      }
    }
}

transform {
  FieldMapper {
    source_table_name = "fake"
    result_table_name = "fake1"
    field_mapper = {
      age = age
      name = new_name
    }
  }
}

sink {
  Console {
    source_table_name = "fake1"
  }
}

Generate a configmap named seatunnel-config in Kubernetes for the seatunnel.streaming.conf so that we can mount the config content in pod.

kubectl create cm seatunnel-config \
--from-file=seatunnel.streaming.conf=seatunnel.streaming.conf

Once the Flink Kubernetes Operator is running as seen in the previous steps you are ready to submit a Flink (SeaTunnel) job:

Create seatunnel-flink.yaml FlinkDeployment manifest:

apiVersion: flink.apache.org/v1beta1
kind: FlinkDeployment
metadata:
  name: seatunnel-flink-streaming-example
spec:
  image: seatunnel:2.3.8-flink-1.13
  flinkVersion: v1_13
  flinkConfiguration:
    taskmanager.numberOfTaskSlots: "2"
  serviceAccount: flink
  jobManager:
    replicas: 1
    resource:
      memory: "1024m"
      cpu: 1
  taskManager:
    resource:
      memory: "1024m"
      cpu: 1
  podTemplate:
    spec:
      containers:
        - name: flink-main-container
          volumeMounts:
            - name: seatunnel-config
              mountPath: /data/seatunnel.streaming.conf
              subPath: seatunnel.streaming.conf
      volumes:
        - name: seatunnel-config
          configMap:
            name: seatunnel-config
            items:
            - key: seatunnel.streaming.conf
              path: seatunnel.streaming.conf
  job:
    jarURI: local:///opt/seatunnel/starter/seatunnel-flink-13-starter.jar
    entryClass: org.apache.seatunnel.core.starter.flink.SeaTunnelFlink
    args: ["--config", "/data/seatunnel.streaming.conf"]
    parallelism: 2
    upgradeMode: stateless

Run the example application:

kubectl apply -f seatunnel-flink.yaml

In this guide we will use seatunnel.streaming.conf:

env {
  parallelism = 2
  job.mode = "STREAMING"
  checkpoint.interval = 2000
}

source {
  FakeSource {
    parallelism = 2
    result_table_name = "fake"
    row.num = 16
    schema = {
      fields {
        name = "string"
        age = "int"
      }
    }
  }
}

sink {
  Console {
  }
}

Generate a configmap named seatunnel-config in Kubernetes for the seatunnel.streaming.conf so that we can mount the config content in pod.

kubectl create cm seatunnel-config \
--from-file=seatunnel.streaming.conf=seatunnel.streaming.conf

Create seatunnel.yaml:

apiVersion: v1
kind: Pod
metadata:
  name: seatunnel
spec:
  containers:
  - name: seatunnel
    image: seatunnel:2.3.8
    command: ["/bin/sh","-c","/opt/seatunnel/bin/seatunnel.sh --config /data/seatunnel.streaming.conf -e local"]
    resources:
      limits:
        cpu: "1"
        memory: 4G
      requests:
        cpu: "1"
        memory: 2G
    volumeMounts:
      - name: seatunnel-config
        mountPath: /data/seatunnel.streaming.conf
        subPath: seatunnel.streaming.conf
  volumes:
        - name: seatunnel-config
          configMap:
            name: seatunnel-config
            items:
            - key: seatunnel.streaming.conf
              path: seatunnel.streaming.conf

Run the example application:

kubectl apply -f seatunnel.yaml

In this guide we will use seatunnel.streaming.conf:

env {
  parallelism = 2
  job.mode = "STREAMING"
  checkpoint.interval = 2000
}

source {
  FakeSource {
    parallelism = 2
    result_table_name = "fake"
    row.num = 16
    schema = {
      fields {
        name = "string"
        age = "int"
      }
    }
  }
}

sink {
  Console {
  }
}

Generate a configmap named seatunnel-config in Kubernetes for the seatunnel.streaming.conf so that we can mount the config content in pod.

kubectl create cm seatunnel-config \
--from-file=seatunnel.streaming.conf=seatunnel.streaming.conf

Then, we use the following command to load some configuration files used by the seatunnel cluster into the configmap

Create the yaml file locally as follows

Create hazelcast-client.yaml:

hazelcast-client:
  cluster-name: seatunnel
  properties:
    hazelcast.logging.type: log4j2
  network:
    cluster-members:
      - localhost:5801

Create hazelcast.yaml:

hazelcast:
  cluster-name: seatunnel
  network:
    rest-api:
      enabled: true
      endpoint-groups:
        CLUSTER_WRITE:
          enabled: true
        DATA:
          enabled: true
    join:
      tcp-ip:
        enabled: true
        member-list:
          - localhost
    port:
      auto-increment: false
      port: 5801
  properties:
    hazelcast.invocation.max.retry.count: 20
    hazelcast.tcp.join.port.try.count: 30
    hazelcast.logging.type: log4j2
    hazelcast.operation.generic.thread.count: 50

Create seatunnel.yaml:

seatunnel:
  engine:
    history-job-expire-minutes: 1440
    backup-count: 1
    queue-type: blockingqueue
    print-execution-info-interval: 60
    print-job-metrics-info-interval: 60
    slot-service:
      dynamic-slot: true
    checkpoint:
      interval: 10000
      timeout: 60000
      storage:
        type: hdfs
        max-retained: 3
        plugin-config:
          namespace: /tmp/seatunnel/checkpoint_snapshot
          storage.type: hdfs
          fs.defaultFS: file:///tmp/ # Ensure that the directory has written permission

Create congfigmaps for the configuration file using the following command

kubectl create configmap hazelcast-client  --from-file=hazelcast-client.yaml
kubectl create configmap hazelcast  --from-file=hazelcast.yaml
kubectl create configmap seatunnelmap  --from-file=seatunnel.yaml

Deploy Reloader to achieve hot deployment We use the Reloader here to automatically restart the pod when the configuration file or other modifications are made. You can also directly give the value of the configuration file and do not use the Reloader

Reloader

wget https://raw.githubusercontent.com/stakater/Reloader/master/deployments/kubernetes/reloader.yaml
kubectl apply -f reloader.yaml

Create seatunnel-cluster.yml:

apiVersion: v1
kind: Service

    app: seatunnel
  ports:
  - port: 5801

            requests:
              cpu: "1"
              memory: 2G
          volumeMounts:
            - mountPath: "/opt/seatunnel/config/hazelcast.yaml"
              name: hazelcast
              subPath: hazelcast.yaml
            - mountPath: "/opt/seatunnel/config/hazelcast-client.yaml"
              name: hazelcast-client
              subPath: hazelcast-client.yaml
            - mountPath: "/opt/seatunnel/config/seatunnel.yaml"
              name: seatunnelmap
              subPath: seatunnel.yaml
            - mountPath: /data/seatunnel.streaming.conf
              name: seatunnel-config
              subPath: seatunnel.streaming.conf
      volumes:
        - name: hazelcast
          configMap:
            name: hazelcast
        - name: hazelcast-client
          configMap:
            name: hazelcast-client
        - name: seatunnelmap
          configMap:
            name: seatunnelmap
        - name: seatunnel-config
          configMap:
            name: seatunnel-config
            items:
            - key: seatunnel.streaming.conf
              path: seatunnel.streaming.conf

Starting a cluster:

kubectl apply -f seatunnel-cluster.yml

Then modify the seatunnel configuration in pod using the following command:

kubectl edit cm hazelcast

Change the member-list option to your cluster address

This uses the headless service access mode

The format for accessing between general pods is [pod-name].[service-name].[namespace].svc.cluster.local

for example:

- seatunnel-0.seatunnel.default.svc.cluster.local
- seatunnel-1.seatunnel.default.svc.cluster.local
- seatunnel-2.seatunnel.default.svc.cluster.local

kubectl edit cm hazelcast-client

Change the cluster-members option to your cluster address

for example:

- seatunnel-0.seatunnel.default.svc.cluster.local:5801
- seatunnel-1.seatunnel.default.svc.cluster.local:5801
- seatunnel-2.seatunnel.default.svc.cluster.local:5801

Later, you will see that the pod automatically restarts and updates the seatunnel configuration

kubectl edit cm hazelcast-client

After we wait for all pod updates to be completed, we can use the following command to check if the configuration inside the pod has been updated

kubectl exec -it  seatunnel-0  -- cat /opt/seatunnel/config/hazelcast-client.yaml

Afterwards, we can submit tasks to any pod

kubectl exec -it  seatunnel-0  -- /opt/seatunnel/bin/seatunnel.sh --config /data/seatunnel.streaming.conf

You may follow the logs of your job, after a successful startup (which can take on the order of a minute in a fresh environment, seconds afterwards) you can:

kubectl logs -f deploy/seatunnel-flink-streaming-example

looks like the below:

...

If OOM error accur in the log, you can decrease the row.num value in seatunnel.streaming.conf

To expose the Flink Dashboard you may add a port-forward rule:

kubectl port-forward svc/seatunnel-flink-streaming-example-rest 8081

Now the Flink Dashboard is accessible at localhost:8081.

Or launch minikube dashboard for a web-based Kubernetes user interface.

The content printed in the TaskManager Stdout log:

kubectl logs \
-l 'app in (seatunnel-flink-streaming-example), component in (taskmanager)' \
--tail=-1 \
-f

looks like the below (your content may be different since we use FakeSource to automatically generate random stream data):

...

To stop your job and delete your FlinkDeployment you can simply:

kubectl delete -f seatunnel-flink.yaml

You may follow the logs of your job, after a successful startup (which can take on the order of a minute in a fresh environment, seconds afterwards) you can:

kubectl logs -f  seatunnel

To stop your job and delete your FlinkDeployment you can simply:

kubectl delete -f seatunnel.yaml

You may follow the logs of your job, after a successful startup (which can take on the order of a minute in a fresh environment, seconds afterwards) you can:

kubectl exec -it  seatunnel-1  -- tail -f /opt/seatunnel/logs/seatunnel-engine-server.log | grep ConsoleSinkWriter

looks like the below (your content may be different since we use FakeSource to automatically generate random stream data):
