我目前正在尝试使用Botkit框架创建一个Messenger Bot！
由于我在不同的计算机上工作，我想使用docker来防止任何本地配置问题。
不幸的是，我是botkit和docker的新手。

我不明白docker如何找不到我的package.json文件，因为通过运行docker-compose build而它确实创建了该文件。我想退出代码0问题来自这里，但我真的不明白为什么。 也许我对docker的实际工作方式缺乏一些基本的了解。
我搜索了有关退出代码0的其他问题，但没有一个答案有用。
最后，我只想在我的app容器上运行bash，以便开始构建我的机器人。
感谢您提供进一步的帮助！
答案 0 :(得分：2)
您必须了解Docker在构建映像之前需要准备一个用于构建文件的上下文。你有你的package.json，但你从未真正将它添加到你的图像上下文中。
您应该从Dockerfile文档中了解final_list = []
lists = [Foo, Bar, Baz]
for lst in lists:
for dct in lst:
id_to_lookup = dct['_id']
found_duplicate_flag = 0
for final_dict in final_list:
if final_dict['_id'] == id_to_lookup:
found_duplicate_flag = 1
final_dict['count_enabled'] += dct['count_enabled']
final_dict['count_disabled'] += dct['count_disabled']
break
if found_duplicate_flag == 0:
final_list.append(dct)
。
COPY指令将从
中的容器文件系统COPY <src> <dest>复制新文件并将其添加到＆gt;路径<src>

尝试tty: true：
节点：
build: ./docker/node volumes_from: - "app" tty: true
这对我来说适用于PHP和MySQL容器。
