I followed the https://www.elastic.co/en/blog/how-to-make-a-dockerfile-for-elasticsearch tutorial to create a Dockerfile and install elasticsearch on Heroku, but when I deploy I get the message from error:
Unable to locate package oracle-java8-installer
The command '/bin/sh -c apt-get install --no-install-recommends -y oracle-java8-installer' returned a non-zero code: 100
I understand that you are probably having trouble installing java 8, but I have already researched it and have not figured out how to do it in a way that works. Anyone who has ever gone through this and / or know how to solve this problem could give me some help?
