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。

文件结构

bot
├── README.md
├── docker
│   ├── botkit
│   │   └── Dockerfile
│   └── node
│       └── Dockerfile
├── docker-compose.yml

└── package.json

4 directories, 5 files

码头工人-compose.yml

version: "2"
services:
    node:
        build: ./docker/node
        volumes_from:
            - "app"
    botkit:
        build: ./docker/botkit
        links:
            - "node"
        volumes_from:
            - "app"
    app:
        image: "node:8"
        working_dir: /home/nook_bot
        environment:
            - NODE_ENV=production
        volumes:
            - .:/home/nook_bot
            - /home/nook_bot/node_modules
        command: "npm init --yes && npm start"

docker/botkit/Dockerfile

FROM node:8
RUN npm install botkit

码头工人/节点/Dockerfile

FROM node:8
EXPOSE 8888

重现错误的步骤

当我跑

docker-compose build

我有

然后我做

我明白了

如果我跑

docker exec -ti nook_bot_app_1 bash

我明白了

Error response from daemon: Container a4c9724bc954c6bab19a5953c2fea315b95caf64f26c8ca0b036ca3f037fd398 is not running

日志

我跑了

docker logs nook_bot_app_1

我明白了

  "version": "1.0.0",
  "description": "",

}

我不明白为什么 docker 找不到我的 package.json 文件,因为通过运行 docker-compose build 和 up 它确实创建了文件。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,但没有一个答案有帮助。

最后,我只想在我的应用程序容器上运行 bash 以开始构建我的机器人。

感谢您的进一步帮助!

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。

您必须了解 Docker 在构建映像之前需要准备一个上下文来构建您的文件。你有你的 package.json,但你从来没有真正将它添加到你的图像上下文中。

您应该阅读COPY <src> <dest>Dockerfile 文档。

COPY 指令将从<src>路径复制新文件并将它们添加到 > 容器的文件系统中<dest>
