flink作业部署

我试图在kubernetes集群（azureaks）中部署一个flink作业。作业群集刚启动就被中止，但任务管理器运行正常。
docker映像创建成功，没有任何异常。我能够运行docker映像以及ssh到docker映像。
我遵循了以下链接中提到的步骤：
https://github.com/apache/flink/tree/release-1.9/flink-container/kubernetes
在创建图像时，我提供了jobjar，它被复制到图像中的“/opt/artifacts”上。但仍然不明白为什么在作业集群pod日志中出现以下异常。

Caused by: org.apache.flink.util.FlinkException: Failed to find job JAR on class path. Please provide the job class name explicitly.

我是kubernetes的新手，你能给我一些线索来调试这个问题吗。
请查看以下完整日志：

develk@ACIDLAELKV01:~/cntx_eng$

现在，我在“job cluster job.yaml.template”文件的参数部分添加了作业类名。
如下所示：

args: ["job-cluster", 
               "--job-classname", "com.flink.wordCountSimple",
               "-Djobmanager.rpc.address=flink-job-cluster",

但在那之后我得到了以下例外：

Caused by: org.apache.flink.util.FlinkException: Could not load the provided entrypoint class.

docker文件

FROM flink:1.9

ARG JAR_FILE=""

ENV APP_OPTS ""
ENV JAVA_OPTS ""
ENV JOB_MANAGER=""

# Build arg allows passing the version at runtime

ARG VERSION=unset-version

COPY flink-conf.yml $FLINK_HOME/conf/flink-conf.yaml

COPY  target/$JAR_FILE $FLINK_HOME/lib/event-tracker.jar

COPY docker-cluster-entrypoint.sh /docker-cluster-entrypoint.sh

RUN apt-get update && apt-get install procps -y && apt-get install curl -y
RUN echo "root:root" | chpasswd

RUN chmod 777 /docker-cluster-entrypoint.sh
RUN chmod 777 $FLINK_HOME/lib/event-tracker.jar

ENTRYPOINT [ "bash","/docker-cluster-entrypoint.sh" ]

docker-cluster-entrypoint.sh文件

FLINK_HOME=${FLINK_HOME:-"/opt/flink/bin"}

JOB_CLUSTER="job-cluster"
TASK_MANAGER="task-manager"

CMD="$1"
shift;

if [ "${CMD}" = "--help" -o "${CMD}" = "-h" ]; then
    echo "Usage: $(basename $0) (${JOB_CLUSTER}|${TASK_MANAGER})"
    exit 0
elif [ "${CMD}" = "${JOB_CLUSTER}" -o "${CMD}" = "${TASK_MANAGER}" ]; then
    echo "Starting the ${CMD}"

    if [ "${CMD}" = "${TASK_MANAGER}" ]; then
        exec $FLINK_HOME/bin/taskmanager.sh start-foreground "$@"
    else
        exec $FLINK_HOME/bin/standalone-job.sh start-foreground "$@"
    fi
fi

如何run:-

mvn clean install

docker-compose -f docker-compose.local.yml up --scale taskmanager=2 >  exceptionlog.log

docker-compose -f docker-compose.local.yml build

这是运行docker的整个conf。但是如果您想在kube中运行，只需将docker compose文件转换为相应的kube文件…其余文件可以保持不变。。可能是这样做一个 Helm 库比维修更好。

这里有一个完整的工作示例，说明如何在中的kubernetes上创建和运行flink作业集群https://github.com/alpinegizmo/flink-containers-example. 也许这会有帮助。另请参见https://www.youtube.com/watch?v=ceztudgh2te.
