从tar文件中提取和加载图像的区别

我有一个使用docker编写的系统。

version: '3'
services:
  base:
    container_name: base
    image: <hub host>/base
    build:
      context: ..
      dockerfile: BaseDockerfile
    environment: 
      - PYTHONPATH=/usr/local/lib/python3.6/site-packages
    volumes:
      - data:/volumes/data/
  postgres:
    container_name: postgres
    image: "postgres:latest"
    ports:
      - 5432:5432

现在,我使用这个docker以两种不同的方式编写文件-在线和离线。

在联机模式下运行 docker-compose build 然后 docker-compose push 然后ssh到服务器,我要部署它,拉取映像并运行( docker-compose pull && docker-compose up ).

在我运行的脱机方法中 docker合成生成 (与第一个相同)然后 docker save 将每个图像加载到.tar文件中,然后使用 docker load -i <file name> 方法,然后运行 docker-compose up

出于某种原因,我在脱机方法中得到一个错误(与numpy包不匹配有关),但在服务器中没有。

我试过docker system prune && docker volume prune

关于这两种方法之间的区别有什么想法吗?

编辑: 保存码头工人:

#!/usr/bin/env bash
for image in $docker_hub/base redis postgres
do
    echo "Saving $image"
    docker save $image | gzip > $directory/${image//$docker_hub}.tar.gz
done

图像加载:

print "Loading images"
for file in ./*.tar.gz
do
    echo "Loading file: "$file
    docker load -i $file
done
