Apache操作符-如何覆盖码头入口点？

Question

我试图在Dockerfile中对Flink应用程序进行覆盖容器入口点，但看起来Apache Flink kubernetes算子忽略了它。

Dockerfile如下：

FROM flink:1.14.2-scala_2.12-java11

ENV FLINK_HOME=/opt/flink

COPY custom-docker-entrypoint.sh /
RUN chmod a+x /custom-docker-entrypoint.sh
COPY --chown=flink:flink --from=build /target/*.jar /opt/flink/flink-web-upload/

ENTRYPOINT ["/custom-docker-entrypoint.sh"]
EXPOSE 6123 8081
CMD ["help"]

FlinkDeployment的定义使用了新的映像：

apiVersion: flink.apache.org/v1beta1
kind: FlinkDeployment
metadata:
  name: flink-example
  namespace: default
spec:
  image: "flink-example:0.1.0"
#...

在豆荚的描述中

kubectl describe pod flink-example

我看到以下输出：

Containers:
  flink-main-container:
    Command:
      /docker-entrypoint.sh

我还试图在主容器的custom-docker-entrypoint.sh命令中定义

apiVersion: flink.apache.org/v1beta1
kind: FlinkDeployment
metadata:
  name: flink-example
  namespace: default
spec:
  flinkVersion: v1_14
  image: "flink-example:0.1.0"
  podTemplate:
    apiVersion: v1
    kind: Pod
    metadata:
      name: pod-template
    spec:
      containers:
        - name: flink-main-container
#          command: [ 'sh','-c','/custom-docker-entrypoint.sh' ]
          command: [ "/custom-docker-entrypoint.sh" ]

谢谢。

您可以通过以下方式覆盖它：

  flinkConfiguration:
    kubernetes.entry.path: "/custom-docker-entrypoint.sh"

运算符(默认情况下)使用Flink的本地Kubernetes集成。请参阅：https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/config/#kubernetes-entry-path
