BellSoft has launched Alpaquita Linux, an working system based mostly upon Alpine Linux, optimized for containerized Java functions. A plain Docker picture is accessible, in addition to Docker pictures with Liberica JDK or JRE or a Native Picture Package based mostly upon GraalVM.
Alternatively, Alpaquita Linux will be put in through Home windows Subsystem for Linux (WSL), Linux repositories or an ISO file.
Alpaquita Linux presents some extra advantages reminiscent of LTS releases, help for the musl and glibc C normal libraries and fashionable security measures with quick safety patches for each the working system and the Java runtime. Safety choices embody the kernel lockdown function which makes it not possible to instantly or not directly entry a working kernel picture. The kernel module signing is an alternative choice and works with SHA-512 to disallow loading modules with invalid keys and unsigned modules. The small variety of working system elements reduces the assault floor. Hardening is supported with userspace compilation choices such because the -Wformat-security argument which points a warning for format features which can trigger safety points.
The working system helps kernel module compression, and accommodates the malloc implementations mimalloc, jemalloc and rpmalloc.
That is the one Linux working system optimized for Java functions with a TCK-verified runtime and optimized reminiscence consumption.
BellSoft gives 4 years help for Lengthy Time period Assist (LTS) releases, two years greater than Alpine Linux. The present LTS is launched this yr and the subsequent one shall be launched in 2024. BellSoft presents numerous industrial help plans.
The Alpaquita Linux Docker picture based mostly on musl is 3.22 MB and the picture based mostly on glibc is 7.8 MB. That is only a bit greater than the Alpine Docker pictures which begin at lower than 2.5 MB. Further Docker pictures with Python or GCC can be found as properly.
Alternatively, the Liberica Runtime Container, based mostly on Alpaquita Linux, could also be used for Java functions. Docker pictures can be found for Java 8, 11 and 17 the place the smallest JRE and JDK pictures for Java 17 are lower than 75MB. The photographs are based mostly upon Liberica Lite which is optimized for measurement, efficiency and cloud deployments.
The final different based mostly on Alpaquita Linux is the Liberica Native Picture Package (NIK) which makes use of GraalVM. Docker pictures can be found for Java 11 and 17, the place the Java 17 pictures begin at a bit greater than 308 MB. The equipment could also be used to compile JVM functions into forward of time compiled native executables that provide sooner startup occasions and decrease reminiscence consumption in comparison with conventional functions. The executable binary file accommodates the applying, dependencies and runtime elements together with the Java Digital Machine (JVM). Purposes written in JVM languages reminiscent of Java, Kotlin, Scala and Groovy could also be transformed into executables. The Native Picture Package works on Home windows, Linux and macOS on machines with x86, x64 or ARM processors (Linux solely).
Alpaquita Linux is a part of the Alpaquita Cloud Native Platform along with Liberica JDK Lite and Liberica Native Picture Package (NIK).
