DNS resolution issues in K8 environment due to Alpine base image

[YordanPavlov]

We are running the 'kafka-docker' image as an init container in our AWS clusters, for creating needed topics. Very often we have a DNS resolution issue like this:

java.nio.channels.UnresolvedAddressException
	at sun.nio.ch.Net.checkAddress(Net.java:101)
	at sun.nio.ch.SocketChannelImpl.connect(SocketChannelImpl.java:622)
	at org.apache.zookeeper.ClientCnxnSocketNIO.registerAndConnect(ClientCnxnSocketNIO.java:277)
	at org.apache.zookeeper.ClientCnxnSocketNIO.connect(ClientCnxnSocketNIO.java:287)
	at org.apache.zookeeper.ClientCnxn$SendThread.startConnect(ClientCnxn.java:1021)
	at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1064)

this goes on for quite some time bringing the whole deploy into a Crash Loop. Resolving the same DNS from another container works. From our experience and various threads online this is related to DNS issues on Alpine Linux images. Where possible we replace such images with Ubuntu based ones and have such issues resolved immediately and for good. Is anyone also having such problems, and if so is an Ubuntu based image considered?

Thank you!
