Eclipse Temurin for Alpine Linux With musl libc
Alpine Linux is a popular Linux distribution for container workloads because of its small footprint. Contrary to most other Linux distributions, Alpine Linux is not based on the C library created by the GNU project (usually referred to as “glibc”) but uses musl libc instead. So far, OpenJDK has not supported musl libc but only glibc. With Eclipse Temurin 17, this is no longer necessary. We now have separate variants of Eclipse Temurin 17 that are purpose-built for musl libc that can be downloaded as a tarball and are also available as ready-made container images.adoptiumtemurin
