Canbin Zheng updated FLINK-17033:
---------------------------------
Description:
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.
