 # docker-alpine-java-rpi
 Docker image using alpine linux supporting Oracle Java JRE 8
+
+Built for use with resin.io -- I found that the OpenJDK versions were way too slow.
+
+This is jre only -- to get full jdk, edit the Dockerfile to extract the full tarball in /opt, rather than extracting in /tmp and moving the jre to /opt.
+
+You can find the Docker image at docker.io/dpsmyth/docker-alpine-java-raspberrypi3
