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
测试通过
参考
