docker官方镜像下载及使用Dockerfile创建镜像

FROM centos:7.2.1511MAINTAINER wanghongwei(wanghongwei@4paradigm.com)RUN yum install -y expect /       && yum install -y openssh-clients openssh-server sudo rsync vim libaio strace wget telnet lsof lvm2 psmisc net-tools /           && /usr/bin/ssh-keygen -A /              && yum clean all RUN useradd workRUN echo 123456 | passwd --stdin rootRUN echo work123 | passwd --stdin workADD jdk-8u121-linux-x64.tar.gz /home/work#ENTRYPOINT ["/root/docker/images/centos7.2"]5、创建docker镜像：Dockerfile文件在当前路径时用. 标示就可以，如果不在使用绝对路径docker build -t 4paradigm/centos:7.2 .6、启动容器脚本：[root@vmhost PRophet2.0]# cat prophet-3.sh
#!/bin/bash -xvHOST_NAME=prophet-3HOST_ip=172.27.4.5GATEWAY=172.27.0.1ISO_PATH=/root/isoVOLUME_PATH=/home/whwstar/volume/prophet3image=4paradigm/centos:7.2if [ `docker ps -a | grep $HOST_NAME | wc -l` -eq 0 ];then    mkdir -p $VOLUME_PATH    docker run -itd -h $HOST_NAME --name=$HOST_NAME --net=none -v $ISO_PATH:$ISO_PATH -v  $VOLUME_PATH:/home/work $image /bin/bash    pipework br0 $HOST_NAME $HOST_IP/20@$GATEWAY    docker exec -d $HOST_NAME /usr/sbin/sshd -Delif [ `docker ps -a | grep prophet-01 | wc -l` -eq 1 ];then    docker start $HOST_NAME    pipework br0 $HOST_NAME $HOST_IP/20@$GATEWAY    docker exec -d $HOST_NAME /usr/sbin/sshd -Delse    echo "docker start exception"fi
