Canbin Zheng created FLINK-17033: ------------------------------------ Summary: Upgrade OpenJDK docker image for Kubernetes Key: FLINK-17033 URL: https://issues.apache.org/jira/browse/FLINK-17033 Project: Flink Issue Type: Improvement Components: Deployment / Kubernetes Reporter: Canbin Zheng Fix For: 1.11.0
The current docker image {{openjdk:8-jre-alpine}} used by Kubernetes has many problems, here is some of them: # There is no official support for this image since the commit [https://github.com/docker-library/openjdk/commit/3eb0351b208d739fac35345c85e3c6237c2114ec#diff-f95ffa3d1377774732c33f7b8368e099] # [DNS-lookup-5s-delay|https://k8s.imroc.io/troubleshooting/cases/dns-lookup-5s-delay] # [DNS resolver does not read /etc/hosts|https://github.com/golang/go/issues/22846] Therefore, this ticket proposes to investigate an alternative official JDK docker image; I think it's a good choice to use {{openjdk:8-jre-slim}}(184MB) instead, the reasons are as follows: # It has official support from openjdk: [https://github.com/docker-library/docs/blob/master/openjdk/README.md#supported-tags-and-respective-dockerfile-links] # It is based on debian and does not have many problems such as DNS lookup delay. # It's much smaller in size than other official docker images. -- This message was sent by Atlassian Jira (v8.3.4#803005)
