批量刪除正在運行的docker容器

docker rm -f $(docker ps -q)

#刪除正在運行的容器 -q是容器ID docker rm -f $(docker ps -q)docker run -it centos /bin/bash [root@c35acdee94f5 /]# pwd / [root@c35acdee94f5 /]# vim 1.txt bash: vim: command not found [root@c35acdee94f5 /]#

增強centos鏡像

Dockerfile腳本內容

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

自定義Dockerfile腳本名稱

docker build -f /workspace/docker/Dockerfile_mycentos -t mycentos:1.0 .

基于自定義centos鏡像運行容器

vim和ifconfig的命令都支持了。

docker run -it mycentos:1.0 /bin/bash[root@03dbfdb30935 local]# pwd /usr/local [root@03dbfdb30935 local]# vim 1.txt [root@03dbfdb30935 local]# ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500inet 172.17.0.2 netmask 255.255.0.0 broadcast 172.17.255.255ether 02:42:ac:11:00:02 txqueuelen 0 (Ethernet)RX packets 26 bytes 4558 (4.4 KiB)RX errors 0 dropped 0 overruns 0 frame 0TX packets 0 bytes 0 (0.0 B)TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536inet 127.0.0.1 netmask 255.0.0.0loop txqueuelen 1000 (Local Loopback)RX packets 0 bytes 0 (0.0 B)RX errors 0 dropped 0 overruns 0 frame 0TX packets 0 bytes 0 (0.0 B)TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0[root@03dbfdb30935 local]#
