Flink On K8s, build docker image very slowly, is there some way to make it faster?

Hi community , when I run the flink task on k8s , the first thing is that to build the flink task jar to 

Docker Image . I find that It would spend much time to build docker image. Is there some way to makr it faster.
Thank your replay.

Hi Lake,

Usually building a docker image should not take much time (typically less than 2 minutes).

It is probably the network issue that causes the long time for image building. Of course we will need more information (e.g., logs) to confirm that, but according to our experience pulling the base image (based on which the Flink on K8s image will be built) from DockerHub could take quite some time from mainland China (where I assume you are since you're also writing to user-zh).

If this is indeed the case that you met, you can try to modify the "flink-container/docker/Dockerfile", change the line "FROM openjdk:8-jre-alpine" to point to a domestic or local image source.

Hi Lake,

Can you clearly count or identify which steps are taking a long time?

Best,

Vino
