Docker Hub 中 99% 鏡像都是從這個(gè)基礎(chǔ)鏡像過來的 FROM scratch,然后配置需要的軟件和配置來進(jìn)行的構(gòu)建
創(chuàng)建自己的centos
# 1、編寫Dockerfile的文件
[root@iZwz9gcg5lpw0sp5r86b4dZ dockerfile]# cat mydockerfile-centos
FROM centos
MAINTAINER young<123456789@qq.com>
ENV MYPATH /usr/local
WORKDIR $MYPATH
RUN yum -y install vim
RUN yum -y install net-tools
EXPOSE 80
CMD echo $MYPATH
CMD echo "----end----"
CMD /bin/bash
# 2求泰、通過這個(gè)文件構(gòu)建鏡像
# 命令 docker build -f dockerfile文件路徑 -t 鏡像名:[tag]
[root@iZwz9gcg5lpw0sp5r86b4dZ dockerfile]# docker build -f mydockerfile-centos -t mycentos:0.1 .
# 3涛舍、測(cè)試運(yùn)行
我們可以列出本地運(yùn)行的變更歷史
