Docker环境搭建

Docker概念

镜像(images) 镜像就是环境包容器(Container) 容器就是镜像的实例, 一个镜像可以启动多个容器

Windows docker环境搭建:

VirtualBox官网:

https://www.virtualbox.org/

下载boot2docker.iso

https://github.com/boot2docker/boot2docker/releases

虚拟机搭建

打开VirtualBox，新建虚拟机

网络和共享文件夹配置

Ctrl+S进入设置
配置docker环境

启动boot2docker虚拟机

$ ifconfig 找到网卡2(eth1)ip地址为192.168.56.101

使用ssh工具连接到docker(这里演示MobaXterm_Personal) ip:192.168.56.101 user:docker password:tcuser

配置docker镜像加速

docker@boot2docker:~$ sudo su
root@boot2docker:/home/docker# cd /etc/docker
root@boot2docker:/etc/docker# vi dameon.json
root@boot2docker:/etc/docker# touch dameon.json
{
 "registry-mirrors": ["http://hub-mirror.c.163.com"]
}
root@boot2docker:/etc/docker# /etc/init.d/docker restart
root@boot2docker:/etc/docker# exit
docker@boot2docker:~$

dameon.json:

{
 "registry-mirrors": ["http://hub-mirror.c.163.com"]
}

Ubuntu docker环境搭建(Ubuntu版本建议大于16.04):

国内 daocloud 一键安装命令：

$ curl -sSL https://get.daocloud.io/docker | sh
更新最新软件包:

$ sudo apt-get update
安装 apt 依赖包，用于通过HTTPS来获取仓库:

$ sudo apt-get install \ apt-transport-https \ ca-certificates \ curl \ gnupg-agent \ software-properties-common
添加 Docker 的官方 GPG 密钥：

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 通过搜索指纹的后8个字符，验证您现在是否拥有带有指纹的密钥。
$ sudo apt-key fingerprint 0EBFCD88

pub rsa4096 2017-02-22 [SCEA]
```
 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
```
uid [ unknown] Docker Release (CE deb) docker@docker.com sub rsa4096 2017-02-22 [S]
使用以下指令设置稳定版仓库

$ sudo add-apt-repository \ “deb [arch=amd64] https://download.docker.com/linux/ubuntu \ $(lsb_release -cs) \ stable”
安装最新版本的 Docker Engine-Community 和 containerd ，或者转到下一步安装特定版本：

$ sudo apt-get update $ sudo apt-get install docker-ce docker-ce-cli containerd.io
要安装特定版本的 Docker Engine-Community，请在仓库中列出可用版本，然后选择一种安装。列出您的仓库中可用的版本：

$ apt-cache madison docker-ce docker-ce | 5:18.09.1~3-0~ubuntu-xenial | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 5:18.09.0~3-0~ubuntu-xenial | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 18.06.1~ce~3-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 18.06.0~ce~3-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages …
使用第二列中的版本字符串安装特定版本，例如 5:18.09.1~3-0~ubuntu-xenial

$ sudo apt-get install docker-ce= docker-ce-cli= containerd.io
测试 Docker 是否安装成功，输入以下指令，打印出以下信息则安装成功:

sudo docker info
如果要使用 Docker 作为非 root 用户，则应考虑使用类似以下方式将用户添加到 docker 组：

$ sudo usermod -aG docker your-user

Docker常用命令

下载镜像

docker pull xxxxOS

上传镜像

docker push xxxxOS:v1

删除容器

docker rm -f centos7

创建容器

docker run —privileged —name centos7 -v /mnt/sda1:/work -p 24:22 -itd centos7 :v1 /usr/sbin/init

运行容器

docker start centos7

停止容器

docker stop centos7

在终端以交互模式进入容器

docker exec -it centos7 /bin/bash

QEMU环境搭建

软件环境准备

windows qemu环境下载：

https://gitee.com/DAI_David/qemu_imx6ull_windows/repository/archive/master.zip

ComEmu终端官网：

https://conemu.github.io/

SSH工具下载：

根据个人爱好下载自己ssh工具，本文演示的是MobaXterm_Personal

环境部署

使用ComEmu运行qemu

解压DAI_David-qemu_imx6ull_windows-master.zip到本地电脑

打开ComEmu：

$ cd d:\Download\DAI_David-qemu_imx6ull_windows-master\qemu_imx6ull_windows
$ QEMU_WIN.bat nogui
显示qemu_imx6ul login:，输入用户名:root 密码:123456
[root@qemu_imx6ul:~]#

ssh工具远程连接Qemu

配置ssh: ip:127.0.0.1 user:root password:123456

容器环境搭建

Ubuntu docker镜像

方法一：通过网络下载Ubuntu docker镜像 docker@boot2docker:~$ docker pull silencedai/ubuntu16.04:cross_v1.0 docker@boot2docker:~$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE silencedai/ubuntu16.04 cross_v1.0 477e1767707c 1 minutes ago 351MB docker@boot2docker:~$ docker tag silencedai/ubuntu16.04:cross_v1.0 ubuntu16.04:cross_v1.0 #修改镜像名称为ubuntu16.04:cross_v1.0 docker@boot2docker:~$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE ubuntu16.04 cross_v1.0 477e1767707c 1 minutes ago 351MB silencedai/ubuntu16.04 cross_v1.0 477e1767707c 1 minutes ago 351MB docker@boot2docker:~$ cd /share/ docker@boot2docker:/share$ docker save -o ubuntu16.04_cross.tar ubuntu16.04:cross_v1.0 #保存镜像为tar包方法二：下载镜像压缩包导入 docker@boot2docker:~$ cd /share docker@boot2docker:/share$ docker load < ubuntu16.04_cross.tar.bz2 Loaded image: ubuntu16.04:cross_v1.0 docker@boot2docker:/share$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE ubuntu16.04 cross_v1.0 477e1767707c 1 minutes ago 351MB
启动Ubuntu docker镜像

docker@boot2docker:~$ ubuntu.sh run ubuntu16.04:cross_v1.0 PS：如果提示：”docker: Error response from daemon: cgroups: cannot find cgroup mount destination: unknown.” 解决办法： docker@boot2docker:~$ sudo cgroup.sh docker@boot2docker:~$ docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 2110559d37fb ubuntu16.04:cross_v1.0 “systemd” 5 minutes ago Created 0.0.0.0:24->22/tcp ubuntu16.04 docker@boot2docker:~$ docker rm -f ubuntu16.04 docker@boot2docker:~$ ubuntu.sh run ubuntu16.04:cross_v1.0 docker@boot2docker:~$ docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 07b86898f1f3 ubuntu16.04:cross_v1.0 “systemd” 10 seconds ago Up 9 seconds 0.0.0.0:24->22/tcp ubuntu16.04
进入ubuntu16.04容器
方法一：使用exec进入容器 docker@boot2docker:~$ docker exec -it ubuntu16.04 bash root@07b86898f1f3:/# 方法二：使用SSH连接容器配置ssh: ip:192.168.56.101
```
  port:24
```
user:work password:123456 work@07b86898f1f3:~$
虚拟机重启后，使用docker start启动容器

此时容器属于Exited状态 docker@boot2docker:~$ docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 07b86898f1f3 ubuntu16.04:cross_v1.0 “systemd” 7 minutes ago Exited (137) 2 seconds ago ubuntu16.04 docker@boot2docker:~$ docker start ubuntu16.04 #启动容器 docker@boot2docker:~$ docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 07b86898f1f3 ubuntu16.04:cross_v1.0 “systemd” 9 minutes ago Up 5 seconds 0.0.0.0:24->22/tcp ubuntu16.04
