【Docker】docker常用指令

开启docker，并设置开机自启动

老式写法：

新式写法：

systemctl start docker.servicesystemctl enable docker.service

Build an image from a Dockerfile

docker build -t friendlyhello .

tag一个image，并push

语法：

docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]docker push username/repository:tag

示例：

[root@localhost ~]# docker login //登录[root@localhost ~]# docker tag friendlyhello ssslinppp/get-started:part1 //tag[root@localhost ~]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEfriendlyhello latest 0a60bcfe3e8d 28 minutes ago 194MBssslinppp/get-started part1 0a60bcfe3e8d 28 minutes ago 194MBpython 2.7-slim d962f7a9f2f1 2 weeks ago 182MBhello-world latest 1815c82652c0 3 weeks ago 1.84kB[root@localhost ~]# docker push ssslinppp/get-started:part1 //上传[root@localhost ~]# docker run -p 4000:80 ssslinppp/get-started:part1 //运行测试 * Running on (Press CTRL+C to quit)

容器相关操作

在容器内运行进程

# 后台执行docker exec -d containerID CMDdocker exec -d containerID touch /etc/new_config_file # 示例# 交互式执行docker exec -t -i containerID /bin/bash

查看容器内进程

docker top containerID

查看容器详细信息

docker inspect containerID

查看容器的端口映射情况

docker port containerID

镜像相关操作

查看镜像是如何被构建出来

docker history imageID
