OpenWrt Docker image with Oracle Java

Basic Docker image to run Java applications. This is based off OpenWrt to keep the size minimal.

This is a version of jeanblanchard/docker-busybox-java with a small modification to base it on the OpenWrt docker image mcreations/openwrt-x64. Note that we only install the server JRE.

Tags

• latest or 8: Oracle Java 8 (Server JRE)

Usage

To just run it and see the java version:

docker run -it --rm mcreations/openwrt-java
