This image is based on Alpine Linux image, which is only a 5MB image, and contains OracleJDK 8.
You must accept the Oracle Binary Code License Agreement for Java SE to use this image (see #6 for details).
JDK bundle contains lots of unnecessary for Docker image stuff, so it was cleaned up. There are 3
tags: full
(only src tarballs get removed), cleaned
(desktop parts get cleaned), slim
(everything but compiler and jvm is removed). master
branch refers to slim
tag, but latest
tag points to cleaned
.

Consider using develar/java
image (~120MB) if you only need JRE (you can run
java applications, but cannot build/compile them).
$ echo 'public class Main { public static void main(String[] args) { System.out.println("Hello World"); } }' > Main.java
$ docker run --rm -v "$(pwd)":/mnt --workdir /mnt frolvlad/alpine-oraclejdk8:slim sh -c "javac Main.java && java Main"
Once you have run this command you will get printed 'Hello World' from Java!
