docker 容器中不支持中文的解决方法

最近的项目中[Docker][]容器中生成的日志文件是中文名字，但是文件名是????.txt

进入容器内部：

**docker exec -t -i 容器名 /bin/bash**

查看容器的语言环境：

\[root@12ec64254bc4 /\]\# **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=

查看容器支持的语言：

\[root@12ec64254bc4 /\]\#** locale -a**  
C  
POSIX  
en\_US.utf8  
zh\_CN.utf8

设置字符集为zh.CN.utf8:

\[root@12ec64254bc4 zhai\]\# **LANG=zh.CN.utf8**

重新加载环境变量：  
\[root@12ec64254bc4 zhai\]\# **source /etc/profile**

再次查看：

\[root@12ec64254bc4 zhai\]\# 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：这样修改只是临时修改。要永久修改，**需要在创建容器时在dockerfile中设置。**

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**'

重建构建容器后，进入容器，查看locale：

\[root@d18364b14af9 /\]\# **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！
