• JDK 16 부터는 나아졌다는 얘기가 있으나(JEP 386: Alpine Linux Port) alpine-musl 과 JDK간의 조합이 여러가지 문제를 일으키는 경우가 있다.
• glibc 기반인 centos, 혹은 debian 계열 docker 이미지를 사용하는게 나아보인다.
• temurin docker의 설명에서도 alpine 계열에 문제가 있을 수 있음이 나온다.(2022년 현재)

This variant is useful when final image size being as small as possible is your primary concern. The main caveat to note is that it does use musl libc instead of glibc and friends, so software will often run into issues depending on the depth of their libc requirements/assumptions. See this Hacker News comment thread for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.
