Minimal Docker image with Java

Basic Docker image to run Java applications. This is based on Alpine Linux to keep the size minimal (about 25% of an ubuntu-based image).

Tags

• latest or 8 or serverjre-8: Oracle Java 8 (Server JRE)
• jdk-8: Oracle Java 8 (JDK)
• jre-8: Oracle Java 8 (JRE)

Additionally, tags are created for each oracle release (e.g. 8u161, jdk-8u161 or jre-8u161).

Note: Sometimes Oracle releases two versions at the same time : a CPU (Critical Patch Update) with only critical bug fixes, and a PSU (Patch Set Update) with additional "non-critical fixes". In this case, the CPU will be the default, as recommended by oracle. If needed, PSU releases are still accessible, by using their specific release tag (e.g jdk-8u162)

Usage

Example:

docker run -it --rm zpaulo/java:8 java -version
