You have many syntax errors in this file, this should be a better start :

USER kafka

CMD /home/lucky/Desktop/script/run.sh

(I’m guessing you’re having a paste issue more than anything here)

But that wont be enough :

  • You should probably add that /home/lucky/Desktop/script/run.sh file inside the image (and probably at a better place).
  • K_TAR is always /tmp/kafka_2.11-0.11.0.0.tgz. You should probably try something like :
ENV KAFKA_VER 0.11.0.0
ENV KAFKA_FULLVER 2.11-$KAFKA_VER
ENV KAFKA_BIN http://www-eu.apache.org/dist/kafka/$KAFKA_VER/kafka_$KAFKA_FULLVER.tgz
ENV K_TAR /tmp/kafka_$KAFKA_FULLVER.tgz
  • Remplace that ugly ln -s $(ls) current with a better link using the versions ENV set ealier.
  • Your actual issue is the wget which return 8 in case of 404 error : the file $KAFKA_BIN is not available on the apache website. you should probably check for a valid version :stuck_out_tongue: (like : http://www-eu.apache.org/dist/kafka/2.2.1/kafka_2.11-2.2.1.tgz aka set KAFKA_VER to 2.2.1)

can you please help with the steps to remove that wget issue

As sebt3 already said:

So to solve your problem, you must change

to

ENV KAFKA_VER 2.2.1

So your wget will do

wget http://www-eu.apache.org/dist/kafka/2.2.1/kafka_2.11-2.2.1.tgz
