Java是基于GUN Standard C library(glibc)
Alpine是基于MUSL libc(mini libc)
所以Alpine跑Java需要安装glibc的库,以下是官方给出wiki
https://wiki.alpinelinux.org/wiki/Running_glibc_programs
至于如何安装,可以参考:
https://github.com/sgerrand/alpine-pkg-glibc
wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://alpine-pkgs.sgerrand.com/sgerrand.rsa.pub wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.32-r0/glibc-2.32-r0.apk apk add glibc-2.32-r0.apk
locals: 本地化，避免中文乱码
wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.32-r0/glibc-bin-2.32-r0.apk wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.32-r0/glibc-i18n-2.32-r0.apk apk add glibc-bin-2.32-r0.apk glibc-i18n-2.32-r0.apk /usr/glibc-compat/bin/localedef -i en_US -f UTF-8 en_US.UTF-8
制作java的dockerfile
