An early access is available as part of java 13. This is the goal of OpenJDK (, that aims to provide a port of the JDK to Alpine Linux, and in-particular the musl C library. If you take a look at the OpenJDK repository, you notice the presence of many C/C++ code (around 19%)! The JVM has been already ported to glibc, but in order to ensure a transparent run of the JVM (and its C/C++ code) on musl, an effort should be made to port the JVM to it as well. The problem is when applications are compiled, they are compiled against a specific libc for the most part and if you want to use them with another libc you have to recompile them. This comparison chart gives a very detailed picture of the differences between the libc implementations available for Linux. Although both are implementation of the same abstraction library, they expose slightly different APIs. However, you won't be surprised to know that the most widely used C library on all major Linux distributions is the GNU C Library, referred to as glibc. This is basically the standardized interface between the kernel and userland, doing such things string handling, mathematical computations, input/output processing, memory management, and several other operating system services. Musl libc is an implementation of libc, the standard library for the C programming language. it provides the core functionalities for dozens of standard programs, such as awk, cp, grep, gzip, sh and top. It combines tiny versions of many common UNIX utilities into a single small executable. Alpine is built around musl libc and busy busybox.īusybox is, as stated by its creator Bruce Perens, "The Swiss Army Knife of Embedded Linux". The official alpine 3.10 docker image has a size of ~3M, compared to 28M for the ubuntu eoan Image, which makes it the favorite distro to use as the base image, where small size is highly desirable. Please use the early-access JDK 13 Alpine Linux build in its place.Īlpine is a security focused, general purpose, lightweight linux distribution. It’s not production-ready because it hasn’t been tested thoroughly enough to be considered a GA build. The Alpine Linux build previously available on this page was removed as of JDK 12.0.1 GA. However, Java developers might find issues while running their containerized applications on alpine as stated on the OpenJdk 12 page: ), and when it comes to lightweight distributions, Alpine Linux is by far the favorite choice. There are considerable benefits of using, building and deploying small container images (small attack surface, faster updates, less network costs.
