進入容器內(nèi)部：
docker exec -t -i 容器名 /bin/bash
查看容器的語言環(huán)境：
[root@c50d94136d8c /]# locale
LANG=
LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_PAPER="POSIX"
LC_NAME="POSIX"
LC_ADDRESS="POSIX"
LC_TELEPHONE="POSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=
查看容器支持的語言：
[root@c50d94136d8c /]# locale -a
C
POSIX
en_US.utf8
zh_CN.utf8
設(shè)置字符集為zh.CN.utf8:
[root@c50d94136d8c zhai]# LANG=zh.CN.utf8
重新加載環(huán)境變量：
[root@c50d94136d8c zhai]# source /etc/profile
再次查看：
[root@security zhai]# locale
LANG=
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC="zh_CN.UTF-8"
LC_TIME="zh_CN.UTF-8"
LC_COLLATE="zh_CN.UTF-8"
LC_MONETARY="zh_CN.UTF-8"
LC_MESSAGES="zh_CN.UTF-8"
LC_PAPER="zh_CN.UTF-8"
LC_NAME="zh_CN.UTF-8"
LC_ADDRESS="zh_CN.UTF-8"
LC_TELEPHONE="zh_CN.UTF-8"
LC_MEASUREMENT="zh_CN.UTF-8"
LC_IDENTIFICATION="zh_CN.UTF-8"
LC_ALL=zh_CN.UTF-8
注意：這樣修改只是臨時修改屹电。要永久修改尔许，需要在創(chuàng)建容器時在dockerfile中設(shè)置。
DOCKER_FILE_CONTENT=$DOCKER_FILE_CONTENT'ENV LANG zh_CN.UTF-8\n'
DOCKER_FILE_CONTENT=$DOCKER_FILE_CONTENT'ENV LC_ALL zh_CN.UTF-8\n'
重建構(gòu)建容器后慎颗，進入容器，查看locale：
[root@f31a974e1710 /]# locale
LANG=zh_CN.UTF-8
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC="zh_CN.UTF-8"
LC_TIME="zh_CN.UTF-8"
LC_COLLATE="zh_CN.UTF-8"
LC_MONETARY="zh_CN.UTF-8"
LC_MESSAGES="zh_CN.UTF-8"
LC_PAPER="zh_CN.UTF-8"
LC_NAME="zh_CN.UTF-8"
LC_ADDRESS="zh_CN.UTF-8"
LC_TELEPHONE="zh_CN.UTF-8"
LC_MEASUREMENT="zh_CN.UTF-8"
LC_IDENTIFICATION="zh_CN.UTF-8"
LC_ALL=zh_CN.UTF-8
修改成功气嫁！
