导读:随着Kubernetes的普及和发展,越来越多的企业和团队开始使用Kubernetes来管理和部署应用程序。然而,Kubernetes的默认工作方式可能不是最佳的选择,尤其是在需要更高效、更可靠的应用程序部署和管理能力时。因此,SeaTunnel提供了一种运行Zeta引擎(local-mode模式)的方法,可以让Kubernetes在本地运行Zeta引擎,实现更高效的应用程序部署和管理。在本文中,我们将探索SeaTunnel k8s运行zeta引擎(local-mode模式)的更多信息,了解如何更好地利用Zeta引擎的优势。

运行

  1. 将SeaTunnel上传至服务器上。我之前已经解压并执行过install-plugin.sh,这里为了方便,我直接用的执行过install-plugin.sh脚本之后的seatunnel做演示。

执行过install-plugin后的lib目录包含如下

file

tar -zxvf apache-seatunnel-2.3.3-bin.tar.gz
sh apache-seatunnel-2.3.3/bin/install-plugin.sh
tar -czvf  apache-seatunnel-2.3.3-bin.tar.gz  apache-seatunnel-2.3.3
  1. 构建SeaTunnel镜像。在安装seatunnel的同级文件夹下创建Dockerfile。配置如下,可自行选择版本
FROM openjdk:8

ENV SEATUNNEL_VERSION="2.3.3"
COPY /apache-seatunnel-${SEATUNNEL_VERSION}-bin.tar.gz /opt/apache-seatunnel-${SEATUNNEL_VERSION}-bin.tar.gz
WORKDIR /opt
RUN tar -xzvf apache-seatunnel-${SEATUNNEL_VERSION}-bin.tar.gz
RUN mv apache-seatunnel-${SEATUNNEL_VERSION} seatunnel
RUN rm -f /opt/apache-seatunnel-${SEATUNNEL_VERSION}-bin.tar.gz
WORKDIR /opt/seatunnel

执行命令

docker build -t seatunnel:2.3.3 -f Dockerfile.
  1. 查看镜像
docker images

如下所示镜像

file

  1. 将镜像load进k8s,这里用的minikube做演示
minikube image load seatunnel:2.3.3

5.

minikube image ls 

查看镜像

file

  1. 创建seatunnel.streaming.conf 如下所示
env {
  execution.parallelism = 1
  job.mode = "STREAMING"
  checkpoint.interval = 2000
}

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

transform {

}

sink {
  Console {}
}
  1. 创建configmap
kubectl create cm seatunnel-config \
--from-file=seatunnel.streaming.conf=seatunnel.streaming.conf
  1. 创建seatunnel.yaml如下示例
    apiVersion: v1
    kind: Pod
    metadata:
    name: seatunneltest
    spec:
    containers:
    - name: seatunnel
     image: seatunnel:2.3.3
     command: ["/bin/sh","-c","/opt/seatunnel/bin/seatunnel.sh --config /data/seatunnel.streaming.conf -e local"]
     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
    ~                                                  

执行

kubectl apply -f seatunnel.yaml

查看pod结果如下 file file
