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

Additional Libraries

JNA

This imaged has a preinstalled JNA library from here. JNA_VERSION environment varibale chooses which release of JNA should install on build.

Test

Test JVM

The script list-system-properties.sh shows how to pass a classpath with -v to the container.

Test JNA

The script jna-c-printf-test.sh tests JNA by mapping the printf function from the standard C library and calling it.
