简单的Mac版Docker封装
之前没有封装过docker文件，所以这个是一个尝试的记录。
我的目录文件如下：
这里面的这个 requirements.txt 是自动生成的。生成方法如下：
安装pipreqs：
pip install pipreqs
进入你的工程所在目录，然后输入下面的命令，等待命令运行结束后，就会生成requirements.txt文件了。
(playwright_tianmao) (base) kaka@KakadeMacBook-Pro playwright_tianmao % pipreqs --encoding=utf8 ./project INFO: Successfully saved requirements file in ./project/requirements.txt
编写Dockerfile
FROM python:3.10 WORKDIR ./project ADD . . RUN pip install -r requirements.txt CMD ["python", "./src/tian_mao.py"]
Dockerfile 文件这么写，具体参数看这Docker Dockerfile。
Docker命令行
好了，重头戏来了，先cd 到文件夹内部，当然需要把Docker这个程序运行起来。
现在执行docker images是没有我新打包的。
(base) kaka@KakadeMacBook-Pro ~ % docker images REPOSITORY TAG IMAGE ID CREATED SIZE clickhouse/clickhouse-server <none> 854810a3ea35 2 months ago 705MB redis alpine 7bf9ac7d3b84 3 months ago 28.1MB mysql/mysql-server 8.0 55af6abb77a6 4 months ago 527MB fp2_0-8.1/app latest 53b297f8c7a6 6 months ago 1.61GB clickhouse/clickhouse-server latest d846490c0466 14 months ago 794MB prom/prometheus latest ccf2871d6122 14 months ago 198MB grafana/grafana-enterprise latest 05048bc21afe 15 months ago 290MB prom/alertmanager latest 44a71f29f42b 18 months ago 55.3MB
我们执行命令：

再次执行docker images:
1 (base) kaka@KakadeMacBook-Pro project % docker images 2 REPOSITORY TAG IMAGE ID CREATED SIZE 3 python/playwright_tianmao latest 24afb40d4b24 5 seconds ago 1.01GB 4 clickhouse/clickhouse-server <none> 854810a3ea35 2 months ago 705MB 5 redis alpine 7bf9ac7d3b84 3 months ago 28.1MB 6 mysql/mysql-server 8.0 55af6abb77a6 4 months ago 527MB 7 fp2_0-8.1/app latest 53b297f8c7a6 7 months ago 1.61GB 8 clickhouse/clickhouse-server latest d846490c0466 14 months ago 794MB 9 prom/prometheus latest ccf2871d6122 14 months ago 198MB 10 grafana/grafana-enterprise latest 05048bc21afe 15 months ago 290MB 11 prom/alertmanager latest 44a71f29f42b 18 months ago 55.3MB 12 (base) kaka@KakadeMacBook-Pro project %
导出的命令:
docker save -o playwright_tianmao.tar python/playwright_tianmao
删除：
(base) kaka@KakadeMacBook-Pro ~ % docker rmi 24afb40d4b24
然后：
docker load -i playwright_tianmao.tar
查看结果：
(base) kaka@KakadeMacBook-Pro project % docker load -i playwright_tianmao.tar
