docker镜像打包及上传到harbor

背景

由于日常需要经常用到某个镜像，所以需要将已经比较稳定的容器生成镜像便于后续复用。
harbar：一个镜像上传的云端仓库，自己搭建即可，地址本文为docker.###.###.com，日常打包文件目录为abc

思路

1、dockerfile构建：后续便于一键构建，但是中间如果出错（如网络等等问题），可能需要清理镜像或容器
2、直接容器构建：不方便后续一键构建，但是过程便于调试清理问题，这里暂时采用该种思路（后续环境基本不变）

实操

1、本地运行容器并在容器中安装所需要的包，调试是否具备脚本运行的环境

 sudo docker run -it --name env_stability -d -v /dev/bus/usb:/dev/bus/usb -e TZ="Asia/Shanghai" --network host --privileged docker.###.###.com/abc/python3.9.5:v2 bash

确认容器运行无误后，进入容器安装所需的环境（各类包等，脚本用到的环境）

docker exec -it env_stability bash

接下来就是环境安装等，如

cat > /etc/apt/sources.list << EOF
# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye main contrib non-free
# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye main contrib non-free
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-updates main contrib non-free
# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-updates main contrib non-free

deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-backports main contrib non-free
# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-backports main contrib non-free

deb https://mirrors.tuna.tsinghua.edu.cn/debian-security bullseye-security main contrib non-free
# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian-security bullseye-security main contrib non-free
EOF

apt update
apt install -y adb

pip3 install -U uiautomator2
pip3 install -U requests

2、以上确认环境ok后，将容器打包成镜像

sudo docker commit 45c4fc07### env_stability:v2

其中45c4fc07###是容器对应的容器id
操作完，可以通过images看到里面已经存在

###@ubuntu:~$ sudo docker images
REPOSITORY                                                        TAG              IMAGE ID       CREATED         SIZE
env_stability                                                     v2               c87ae4f64041   5 seconds ago   1.54GB

3、由于需要上传到自己云端harbor,需要遵循一定的格式才能拉下来使用，所以给当前的镜像打个别名

sudo docker tag env_stability:v2 docker.###.###.com/abc/env_stability:v2

再看一下镜像

###@ubuntu:~$ sudo docker images
REPOSITORY                                                        TAG              IMAGE ID       CREATED              SIZE
env_stability                                                     v2               c87ae4f64041   About a minute ago   1.54GB
docker.###.###.com/abc/env_stability                    v2               c87ae4f64041   About a minute ago   1.54GB

4、通过docker连接上harbor所在仓库

###@ubuntu:~$ sudo docker login http://docker.###.###.com/
Authenticating with existing credentials...
Stored credentials invalid or expired
Username (admin): admin
Password: 
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

5、提交本地的镜像到云端仓库

###@ubuntu:~$ sudo docker push docker.###.###.com/adb/env_stability:v2
The push refers to repository [docker.###.###.com/abc/env_stability]
720eae20260d: Pushed 
c4c5017a38ab: Mounted from iottest/python3.9.5 
0d8eeeffc6a6: Mounted from iottest/python3.9.5 
巴拉巴拉.....

6、云端harbor仓库查看是否推送成功

7、jenkins拉取镜像对比速度
