docker初体验:docker 自己定制镜像

centos7

[root@chaols ~]#  sudo yum remove docker \
>                   docker-client \
>                   docker-client-latest \
>                   docker-common \
>                   docker-latest \
>                   docker-latest-logrotate \
>                   docker-logrotate \
>                   docker-engine

[root@chaols ~]# yum install -y yum-utils

[root@chaols ~]# yum install docker-ce docker-ce-cli containerd.io

[root@chaols ~]# systemctl start docker

刚刚安装docker是没有镜像的

[root@chaols ~]# docker images
REPOSITORY   TAG       IMAGE ID   CREATED   SIZE

[root@chaols ~]# docker pull centos

默认centos镜像没有ifconfig

FROM centos
ENV MYPATH /usr/local
WORKDIR $MYPATH
RUN yum install -y net-tools
RUN yum install -y vim
EXPOSE 80
CMD echo $MYPATH
CMD echo "-----end-----"
CMD /bin/bash"

docker build -f ./dockerfile_chao_centos -t chao.centos:0.1 .

root@chaols ~]# docker run -it --name test chao.centos:0.1 /bin/bash

[root@f5be14eebc1e local]# ifconfig
