Spring Cloud Dataflow/SCDF 2.8.0 in OKD fails

 原文  2021-06-22 14:47:36  2   1    java/ openshift/ spring-cloud-dataflow/ okd

Question

I need to deploy SCDF 2.8.0 version in OKD. I also made changes to SCDF Code to add the Oracle Driver dependency. When I scale up the POD after adding all configurations of SCDF as given in the documentation I get the below error. I tried changing the port but It's of no use.

There are other Rest applications deployed in the same environment and they have no issues in exposing the service via the port 80 or 81. Kindly let me know your inputs.

DockerFile I use to build SCDF Image. I build SCDF jar separately with Oracle driver and just use the below docker file to convert into Dockerimage. This is just to reduce the build time.

DockerFile: 

FROM openjdk:8-jre-alpine

WORKDIR /app
COPY src/main/resources/spring-cloud-dataflow-server-2.8.0.jar /app/

ENTRYPOINT ["java", "-jar", "spring-cloud-dataflow-server-2.8.0.jar"]

Thanks.

After a bit of a research, I found the answer for this question. I get the Caused by: java.net.SocketException: Permission denied error. This denotes that the port I'm using which is 80 for SCDF server is not permitted for use in the particular environment. Hence I changed the port to 8081 (Just to have the usual one) and it's started working fine.
