【Docker】docker常用指令

开启docker，并设置开机自启动

老式写法：

service docker start
chkconfig docker on

新式写法：

systemctl  start docker.service
systemctl  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 images
REPOSITORY              TAG                 IMAGE ID            CREATED             SIZE
friendlyhello           latest              0a60bcfe3e8d        28 minutes ago      194MB
ssslinppp/get-started   part1               0a60bcfe3e8d        28 minutes ago      194MB

[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

容器相关操作

在容器内运行进程

# 后台执行
docker exec -d containerID CMD
docker 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

官方提供的常用命令

docker build -t friendlyname .  # Create image using this directory's Dockerfile
docker run -p 4000:80 friendlyname  # Run "friendlyname" mapping port 4000 to 80
docker run -d -p 4000:80 friendlyname         # Same thing, but in detached mode
docker ps                                 # See a list of all running containers
docker stop <hash>                     # Gracefully stop the specified container
docker ps -a           # See a list of all containers, even the ones not running
docker kill <hash>                   # Force shutdown of the specified container
docker rm <hash>              # Remove the specified container from this machine
docker rm $(docker ps -a -q)           # Remove all containers from this machine
docker images -a                               # Show all images on this machine
docker rmi <imagename>            # Remove the specified image from this machine
docker rmi $(docker images -q)             # Remove all images from this machine
docker login             # Log in this CLI session using your Docker credentials
docker tag <image> username/repository:tag  # Tag <image> for upload to registry
docker push username/repository:tag            # Upload tagged image to registry
docker run username/repository:tag                   # Run image from a registry

docker stack ls              # List all running applications on this Docker host

docker stack ps <appname>   # List the running containers associated with an app
docker stack rm <appname>                             # Tear down an application
