1、使用以下命令发布任务：
./bin/flink run-application \
--target kubernetes-application \
-Dkubernetes.cluster-id=my-first-application-cluster \
-Dkubernetes.container.image=registry.cn-shenzhen.aliyuncs.com/syni_test/flink:v1
\
-Dkubernetes.container.image.pull-policy=Always \
-Dkubernetes.container-start-command-template="%java% %classpath%
%jvmmem% %jvmopts% %logging% %class% %args%" \
local:///opt/flink/usrlib/WordCount.jar
2、任务发布后，pod重启失败，用kubectl logs查看日志，出现以下错误：
/docker-entrypoint.sh: 125: exec: native-k8s: not found
3、检查了镜像的docker-entrypoint.sh脚本，没有navive-k8s的命令，镜像是基于flink最新的镜像进行构筑的，dockerfile如下：
FROM flink:latest
RUN mkdir -p /opt/flink/usrlib
COPY ./WordCount.jar /opt/flink/usrlib/WordCount.jar
3、pod的describe信息
