docker中centos7 中文终结者,制作 docker 精简 jre8 基础镜像

一：默认的centos镜像中locale 显示的是POSIX 这种是不支持中文的

[root@localhost jettoloader]# docker run -it -d harbor.jettech.com/jettechtools/centos:7.9.2009 bash
bb9987d77c1bace9696c046c91dd649d84a27be468d7154bc3ce5c02776cd04d

[root@localhost jettoloader]# docker exec -it bb  bash
[root@f55d4fa11d5c work]# locale

LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MonETARY="POSIX"
LC_MESSAGES="POSIX"

LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=
[root@f55d4fa11d5c work]# cat /etc/locale.conf

[root@f55d4fa11d5c work]# ls /usr/share/locale/zh_CN/

[root@f55d4fa11d5c work]# rpm -qa | grep glibc-common

[root@f55d4fa11d5c work]# rpm -qa | grep kde-l10n-Chinese

二，操作支持

2.1 直接编写看下能否改变成识别中文字体，

写到你的~/.bashrc里吧，然后重启终端

[root@f55d4fa11d5c work]# cat  ~/.bashrc 
# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
	. /etc/bashrc
fi
export LC_ALL=zh_CN.UTF-8
export LANGUAGE=zh_CN.UTF-8
export LANG=zh_CN.UTF-8

[root@f55d4fa11d5c work]# source  ~/.bashrc 
bash: warning: setlocale: LC_ALL: cannot change locale (zh_CN.UTF-8): No such file or directory
bash: warning: setlocale: LC_ALL: cannot change locale (zh_CN.UTF-8)


[root@f55d4fa11d5c work]# locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
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

看效果此

[root@f55d4fa11d5c work]# vi a

执行一下，转化语言环境和字符集

[root@ef3d25d5714d work]# localedef -c -f UTF-8 -i zh_CN zh_CN.utf8

[root@ef3d25d5714d work]# localedef --list-archive

en_ZM

en_ZW

zh_CN.utf8
[root@ef3d25d5714d work]# 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

在测试：

[root@f55d4fa11d5c work]# vi a

方法二：进入docker里配置

#添加中文环境编码，安装两个包 如果有的话就不用装了 我的系统默认有glibc-common 就可以了不用安装kde-l10n-Chinese 
[root@d547146f3672 work]# yum install kde-l10n-Chinese  glibc-common -y

#转化语言环境和字符集 这个是主要的
[root@d547146f3672 work]# localedef -c -f UTF-8 -i zh_CN zh_CN.utf8

#添加定义到系统环境变量
[root@d547146f3672 work]# echo "export LC_ALL=zh_CN.utf8" >> /etc/profile

执行生效
[root@d547146f3672 work]# source /etc/profile

[root@d547146f3672 work]# localedef --list-archive
en_US.utf8
zh_CN.utf8
[root@d547146f3672 work]# locale
LANG=
LC_CTYPE="zh_CN.utf8"
LC_NUMERIC="zh_CN.utf8"
LC_TIME="zh_CN.utf8"
LC_COLLATE="zh_CN.utf8"
LC_MonETARY="zh_CN.utf8"
LC_MESSAGES="zh_CN.utf8"
LC_PAPER="zh_CN.utf8"
LC_NAME="zh_CN.utf8"
LC_ADDRESS="zh_CN.utf8"
LC_TELEPHONE="zh_CN.utf8"
LC_MEASUREMENT="zh_CN.utf8"
LC_IDENTIFICATION="zh_CN.utf8"
LC_ALL=zh_CN.utf8

测试:

[root@d547146f3672 work]# vi a

方法三：编写dockerfile文件

[root@localhost base]# cat Dockerfile 
FROM harbor.jettech.com/jettechtools/centos:7.9.2009
MAINTAINER wu_bo2@hoperun.com
RUN yum install -y wget  net-tools iproute bind-utils lrzsz 
    && rm -rf /var/cache /tmp/* 
    && ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime 
    && localedef -c -f UTF-8 -i zh_CN zh_CN.utf8

#RUN yum install kde-l10n-Chinese -y
#RUN yum install glibc-common -y
#RUN export LANG=zh_CN.UTF-8
#RUN echo "export LANG=zh_CN.UTF-8" >> /etc/locale.conf
#ENV LANG zh_CN.UTF-8
ADD jre-8u321-linux-x64-minimal.tar.gz /usr/java/jdk
ENV LC_ALL zh_CN.UTF-8
ENV JAVA_HOME /usr/java/jdk
ENV PATH ${PATH}:${JAVA_HOME}/bin
WORKDIR /jettech/work

官方jre下载地址：https://www.java.com/en/download/manual.jsp

然后解压JRE包，删除根目录下文本文件，然后删除其他不必要文件，命令如下：

# 解压
[root@localhost base]#tar -zxvf jre-8u321-linux-x64.tar.gz
# 进入目录
[root@localhost base]#cd jre1.8.0_321/
# 删除文本文件
[root@localhost base]#rm -rf COPYRIGHT LICENSE README release THIRDPARTYLICENSEREADME-JAVAFX.txt THIRDPARTYLICENSEREADME.txt Welcome.html
#删除其他无用文件
[root@localhost base]# rm -rf  lib/plugin.jar 
           lib/ext/jfxrt.jar 
           bin/javaws 
           lib/javaws.jar 
           lib/desktop 
           plugin 
           lib/deploy* 
           lib/*javafx* 
           lib/*jfx* 
           lib/amd64/libdecora_sse.so 
           lib/amd64/libprism_*.so 
           lib/amd64/libfxplugins.so 
           lib/amd64/libglass.so 
           lib/amd64/libgstreamer-lite.so 
           lib/amd64/libjavafx*.so 
           lib/amd64/libjfx*.so

重新打包

# 打包，包名增加 -minimal 和原始包名进行区分
[root@localhost base]# tar -zcvf jre-8u321-linux-x64-minimal.tar.gz *

构建镜像

[root@localhost base]# cp jre-8u321-linux-x64-minimal.tar.gz  work/
[root@localhost base]# docker build -t  harbor.jettech.com/jettechtools/centos-jre-8:7.9.2009  -f Dockerfile  work/
