本文详细介绍了如何使用Docker从镜像创建容器，更新软件源，生成新的镜像，并验证更新后的软件源。通过具体步骤，展示了如何在容器内增加阿里云的软件源，然后将修改后的容器保存为新的镜像。

1. 通过镜像创建一个新容器

sudo docker run -i -t huawei-ec-iot/osc-sdk:1.0.0 /bin/bash

说明：

huawei-ec-iot/osc-sdk:1.0.0：为镜像文件

/bin/bash：shell交互环境

2. 在容器内更新源

vi /etc/apt/sources.list
比如增加阿里源：

#添加阿里源
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

3. 在容器内生成镜像

root@b526a8bc923d:/# docker commit b526a8bc923d docker-my-huawei-esdk
sha256:47be42a9f7227cec1c08a2a6d8992e733e996e29fe14494d7c812fee800bbcb4

说明：

docker commit：由容器生成镜像的命令

b526a8bc923d ：当前的容器ID，对应root@b526a8bc923d

docker-my-huawei-esdk：待生成的新的镜像文件

4. 在容器内查看新生成的镜像

root@b526a8bc923d:/# sudo docker images
REPOSITORY              TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
docker-my-huawei-esdk   latest              sha256:47be4        20 seconds ago      1.104 GB

5. 退出当前容器

root@b526a8bc923d:/# exit
exit

6. 启动新的镜像文件

root@ubuntu:~# sudo docker run -i -t docker-my-huawei-esdk:latest /bin/bash

7. 查看第2步骤中是否增加了阿里源

root@8fd945c5b285:/# cat /etc/apt/sources.list
#deb http://ftp.cn.debian.org/debian/ jessie main non-free contrib
#deb http://ftp.cn.debian.org/debian/ jessie-updates main non-free contrib
#deb http://ftp.cn.debian.org/debian-security/ oldoldstable/updates main non-free contrib
#deb http://ftp.cn.debian.org/debian/ jessie-backports main non-free contrib
#deb http://emdebian.org/tools/debian jessie main extra
#deb-src http://emdebian.org/tools/debian jessie main extra


#添加阿里源
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

确实添加成功了，完美收工！！！
