添加ssh服务构建新镜像-docker commit 方式01

添加ssh服务构建新镜像-docker commit 方式

１:docker commit构建自定义镜像---一般不推荐使用这种方式构建新镜像

1:ubuntu基础镜像下载

ubuntu@ubuntu:~$ docker pull ubuntu:18.04

2:运行镜像，启动一个容器

ubuntu@ubuntu:~$ docker run -it ubuntu:18.04 /bin/bash

root@92cf48876d4c:/# 

3:配置软件源

#1:更新

root@92cf48876d4c:/# apt-get update　　　　　

#2:备份

root@92cf48876d4c:/# cp /etc/apt/sources.list /etc/apt/sources.list.bak

#3:安装vim.net-tools

root@92cf48876d4c:/# apt-get install vim　net-tools

#4:将/etc/apt/sources.list下面的内容替换成阿里源

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

#5:更新

root@92cf48876d4c:/# apt-get update

4:安装和配置ssh服务

#1:服务端安装

root@92cf48876d4c:/# apt-get install openssh-server

#2:要正常启动SSH服务，所以手动创建/var/run/sshd目录

root@92cf48876d4c:/# mkdir -p /var/run/sshd

#3:启动sshd服务

root@92cf48876d4c:~# /usr/sbin/sshd -D &

[1] 4122

#4：取消pam登录限制

root@92cf48876d4c:~# sed -ri 's/session    required     pam_loginuid.so/#&/g' /etc/pam.d/sshd

root@92cf48876d4c:~# cat /etc/pam.d/sshd | grep pam_loginuid.so

#session    required     pam_loginuid.so

#5:配置登录秘钥

１:主机(client)生成公钥

ubuntu@ubuntu:~$ ssh-keygen -trsa

Generating public/private rsa key pair.

Enter file in which to save the key (/home/ubuntu/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /home/ubuntu/.ssh/id_rsa.

Your public key has been saved in /home/ubuntu/.ssh/id_rsa.pub.

The key fingerprint is:

SHA256:cCJNE3EeRpucmyTAN4tJ1diGO9TVuaNJ4LkPsJisMOE ubuntu@ubuntu

The key's randomart image is:

+---[RSA 3072]----+

|   ...*X=... .   |

|    o+***=  o    |

|   ..==*Oo   .   |

|.   o.=*oo. o    |

|.. . o +So o .   |

|oE  + . o o      |

| o .     o       |

|  .       .      |

|                 |

+----[SHA256]-----+

一直敲回车就行了

２：在容器中(server)中创建/root/.ssh目录

root@92cf48876d4c:~# mkdir /root/.ssh

３：将client的公钥复制到server的authorized_keys文件中

ubuntu@ubuntu:~$ cat  /home/ubuntu/.ssh/id_rsa.pub

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABgQCuqW0ncbixcQeCllHpudoguBjmxf9vf8GMdGkVrw25M0WlLbLj2gqR2MC6AdzGsPY5VThRkVeGG0UlOA382VeTj68HitC9GTS+goxl1QzPwfPWzgSJ7SNYvYRSnqx5uAuF6IUXiiv57o/CMJGJ/3JOc5jWOL+Kl3aUZExD7dxIkQd9C3BikjZLQa0IobFf5N0uZJNv+MPRwV5CH1+pNzWRo97jYJZ7aHoifT8NXyBN4Gug9Z4rYQWEMpa3B85V0nQRJLdJPiXtgAvlLmtqW8RfoHXXZlq05Oh71uRvhtHYjRi3oz9D/FxfwVBqQVipZuAb1wcYnhOW9xj8TEGDhe4QEK1Owc8spozMWPG4s0fhh3Zx6YsSwi4GAUncPKmPyHyh2MPcWpV0vRmo+Ro9L4jxZ0OCi3h/ALB9zmcVhuctin67mHSK/NX2jaKdXms+VlIJvQS0mDzY6Epr7wGZ+2mZUBq/5HCaZEfq2I68IGEQ3UjIDQ+MaZZ4mWlpesjhNIE= ubuntu@ubuntu

root@92cf48876d4c:~# vi /root/.ssh/authorized_keys

root@92cf48876d4c:~# cat /root/.ssh/authorized_keys

ssh-rsa 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 ubuntu@ubuntu

6:创建自启动的脚本文件

root@92cf48876d4c:~# vi /run.sh

root@92cf48876d4c:~# cat /run.sh

#! /bin/bash

/usr/sbin/sshd -D

root@92cf48876d4c:~# chmod a+x /run.sh 

7:最后退出容器

root@92cf48876d4c:~# exit

exit

8:docker commit 保存为一个新镜像

ubuntu@ubuntu:~$ docker ps -a

9:使用sshd:ubuntu镜像,添加端口映射10022-->22

ubuntu@ubuntu:~$ docker run -p 10022:22 -d sshd:ubuntu /run.sh

cb3b9c80c3b6049a20832a0772b9c9f5ab3815a5c18d7b1e57c66b2b1af8b45b

ubuntu@ubuntu:~$ docker ps -al
