Small Docker image with Oracle Java based on OpenWrt

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)
• 7: Oracle Java 7 (Server JRE)

Usage

To just run it and see the java version:

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