Yang Wang updated FLINK-17033: ------------------------------ Fix Version/s: 1.12.0 > 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 > Priority: Major > Fix For: 1.11.0, 1.12.0 > > > 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] > # It uses musl libc instead of glibc. This could cause a problem if we want > to run native library like intel MKL for native BLAS support > 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)
