阿里云镜像加速器

删除默认的虚拟主机

docker-machine ls
docker-machine rm default

创建一台安装有 Docker 环境的 Linux 虚拟机，指定机器名称为 default，同时配置 Docker 加速器地址。

docker-machine create --engine-registry-mirror=替换url地址 -d virtualbox default

查看机器的环境配置，并配置到本地。然后通过 Docker 客户端访问 Docker 服务。

docker-machine env default
eval "$(docker-machine env default)"
docker info

Oracle VirtualBox

DaoCloud 镜像加速器

DaoCloud 接入自有主机

下载镜像

搜索镜像，组织名或用户名/镜像名称，如果是官方镜像则只有镜像名称 docker search centos

下载镜像 docker pull centos

查看已下载镜像 docker images

容器

运行容器 docker run centos /bin/echo 'Hello World'

查看正在运行的容器 docker ps

查看所有的容器 docker ps --all docker ps -a

删除容器 docker rm 7bb410a19a8d docker rm determined_hamilton

运行容器，并指定容器名称 docker run --name bga centos /bin/echo 'hello bga'

查看最近创建的一个容器 docker ps --all --latest docker ps -a -l docker ps -al

查看容器日志 docker logs bga docker logs e200d7dbb94f

容器的停止与运行 docker stop bga docker restart bga docker start bga

带互动的容器 docker run --interactive --tty centos /bin/bash docker run -i -t centos /bin/bash docker run -it centos /bin/bash

创建一个后台运行的容器 ➜ ~ docker run --detach centos ping github.com 67adab0abebb1c4c6b96faf257e5c8052769f510017d7e6c0be4653cb086df07 ➜ ~ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 67adab0abebb centos "ping github.com" 5 seconds ago Up 4 seconds evil_hugle ➜ ~ ➜ ~ docker run -d centos ping github.com 268cff96ab1e20158cc094551dee2d1b738ee13bf7ab4a6acfe9ebf635909b75 ➜ ~ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 268cff96ab1e centos "ping github.com" About a minute ago Up About a minute mad_mcclintock ➜ ~ ➜ ~ docker logs --follow 268cff96ab1e

51f5af98eba6        bridge              bridge      桥接网络，如果创建的时候不手动指定网络，不然默认就是bridge，容器相互之间可以通信，不过外界想要访问这种网络下的容器的话需要桥接网络，就像容器和主机之间的一座桥，对容器有一个隔离的作用，可以通过绑定端口号的方法让外界和主机之间使用某一个指定的端口进行通信
5b3a9e3a6c9e        host                host        主机网络，跟主机使用的是同样的网络，对外界完全开放的，能够访问到主机就能够到使用host这种网络的容器
8060a77be0f9        none                null         无网络，完全隔离
