Updated on 12Apr.2025 ver1.4
- added option 8. Watching container logs 10.
- added option 9. Create new image from container
注：已经从最早发布的 3 个菜单版本，改到 7 菜单版本。8.添加 Entry container shell 功能
前言：
当昨天在文章中，露出了 $2 域名 daven.us ， 这个域名是可以在公网上访问。 当初为了方便，但任何人都能在主页点 “编辑导航” 去编辑内容。刚添加了IP限制。还改了之前的保存会替换图片的错误，还有一个什么忘了。
修改文件后，要上传到 docker。每次都要敲几次键盘，用脚本替代这些重复操作。
然后想实现的功能，也随着越用也越多。最后是因为名字 docker file copy，增加了从 Container 上下载的功能，最后改为现在版本的样子。
都这么多了，添加第三选项：重启容器；
第四个选项：停止容器；
第五个选项：删除容器与关联 image
第 6 选项：返回选择另一个容器
脚本：
环境：QNAP NAS， QTS-5.x
一、使用方式：
直接运行脚本 dcokerfilescopy.sh :
updated picture on 12Apr.2025.
它猫的，SecureCRT 不能显示颜色。网上抄的这功能没在上图表现出来。大圆点是 绿/红 。
二、功能描述：
- 列出当前主机的所有 Containers 容器
- 容器 Containers 按运行与停止分为两部分，显示在屏幕的上部与下部
- 简化容器的显示信息，只显示：序号，Name，Image，ID，Ports 五个部分，并以此顺序显示
- 使用序号输入，或是 0 退出程序。
- 如果选择的容器是 停止的，会询问启动。
- 输入序号扣，会显示选择的 容器 Container 信息，来确认。 确认使用 Yes/No
- 提示“请选择操作”： 1. 上传文件到容器 2.从容器下载文件 3.重启容器 4.停止容器 5.删除容器与之关联 image 6.选择另一个容器 7.停止容器 .退出
- 当选择 1. 上传文件到容器
- 就会执行文件复制到 容器 Container 的操作。但排除 venv 目录，与所有 "点/dot/."开始的文件与目录
- 复制结束后，会询问 是否重启容器，并列出 容器的名字与ID。确认用 Yes/No
- 重启后会显示，成功。
- 判断容器是否运行。
- 显示运行结果：“文件复制完成” “操作完成，未重启容器” “容器重启成功" "容器正在运行" "操作成功完成” 这几个状态。
- 完成后返回 提示“请选择操作”： 1. 上传文件到容器 2.从容器下载文件 3.重启容器 4.停止容器 5.删除容器与之关联 image 6.选择另一个容器 7.进入容器Shell 8.退出
- 当选择 2.从容器下载文件
- 先会在脚本运行目录上，创建一个 download_from_docker.container 子目录
- 然后执行从 容器 Container 复制全部文件与目录 到 download_from_docker.container 目录下。
- 完成后返回 提示“请选择操作”： 1. 上传文件到容器 2.从容器下载文件 3.重启容器 4.停止容器 5.删除容器与之关联 image 6.选择另一个容器 7.进入容器Shell 8.退出
- 当选择 3.重启容器
- 会立即执行 Container 容器的重启操作。
- 重启后会显示，成功。
- 判断容器是否运行。
- 完成后返回 提示“请选择操作”： 1. 上传文件到容器 2.从容器下载文件 3.重启容器 4.停止容器 5.删除容器与之关联 image 6.选择另一个容器 7.进入容器Shell 8.退出
- 当选择 4.停止容器
- 会立即执行 Container 容器的停止操作
- 容器停止后会显示，成功
- 会判断容器是否运行。
- 完成后返回 提示“请选择操作”： 1. 上传文件到容器 2.从容器下载文件 3.重启容器 4.停止容器 5.删除容器与之关联 image 6.选择另一个容器 7.进入容器Shell 8.退出
- 选择 5. 删除容器与之关联 image
- 会询问是否继续 y/n
- （字面意思）
- 完成后返回 容器选择
- 选择 6. 选择另一个容器
- 选择 7.进入容器的shell
- 退出会返回 提示“请选择操作”： 1. 上传文件到容器 2.从容器下载文件 3.重启容器 4.停止容器 5.删除容器与之关联 image 6.选择另一个容器 7.进入容器Shell 8.退出
- added 选择 8. 监控 Container 日志输出。 按 ctrl+c 退出
- added 选择 9. 使用当前 Container 制作新镜像
- 选择
810 会退出脚本循环。- 返回 “程序结束”
- 列表格式，基于我 laptop 显示器调整的。
- 最后上传的是英文菜单版本。
- 看别人的脚本，加入了进度计数。
上传的版本使用中文提示语。

提示：
- 使用 chmod +x 给脚本执行权力 后运行
四、结束
这是写的并以文章发出的第4个 shell 批处理文件。个人的兴趣爱好，因为重复繁琐，所以编出的乱码。
- 我用的 bash shell
- 使用别人的脚本前，先查看脚本逻辑。
- 本人不承担因脚本运行造成的损失。
- 使用 AI 翻译成中文时，格式有错误，上传替换为英文菜单版本。
- 除非主菜单有变化，才会更新 脚本文件。
笑话：
拿到一台 Linux 系统。
第一件事：删除法语语言包。 一定要在 root 用户下操作~
rm -fr /别真做。再发一张美图。
