今天客户提了个问题过来，说是日志显示中文乱码

查看了客户的基础镜像是alpine的，经度娘出来了一个方案:  
重新打镜像，设置默认的编码格式是中文

dockerfile信息

FROM base-alpine #这里写你的基础镜像
    ENV LANG=C.UTF-8
    
    # Here we install GNU libc (aka glibc) and set C.UTF-8 locale as default.

重新build镜像

进到容器里面查看环境变量会找到这个环境变量`LANG=C.UTF-8`

/ # env
    HOSTNAME=dec5fc33fbe3
    SHLVL=1
    HOME=/root
    TERM=xterm
    PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/java/default/bin
    LANG=C.UTF-8
    GLIBC_VERSION=2.25-r0
    PWD=/
    JAVA_HOME=/usr/java/default
    
    / # /usr/glibc-compat/bin/locale -a 
    C
    C.utf8
    POSIX
