运行docker容器

运行一个 centos 容器
The -i and -t flags can be passed to the exec command to keep an interactive shell open, and you can specify the shell you want to attach after the container ID.

[root@localhost ~]# docker run  -i -t centos /bin/bash
Unable to find image 'centos:latest' locally
latest: Pulling from library/centos

Status: Downloaded newer image for centos:latest

运行 docker 以 daemon 方式运行，host 开放端口 5001，对应容器内端口 5000
The -p means “publish ports”

docker run -d -p 5001:5000 python-flask

退出后的容器是 stopped 状态，现在根据名字 furious_leakey 启动它

docker start furious_leakey

通过 shell 进入到容器中

docker attach furious_leakey

上面运行的容器是交互式容器

docker工作目录在

容器存放在

/var/lib/docker/containers

删除所有 docker 容器

docker rm `docker ps -a -q`

进入到运行中的 docker

docker exec -i -t 82d98bdf2d77046ce52a61f2bab27465db868a97faebe94a83581fc0322e4c26 /bin/bash

docker ps 只显示容器名

docker ps -a --format '{{ .Names }}'

docker 及对应的所有 ip

docker inspect --format='{{.Name}} - {{range .NetworkSettings.Networks}} {{.IPAddress}} {{end}}' $(docker ps -aq)
