Docker-compose 使用数据和 nodejs 服务器设置 mongodb

Question

我想用 docker compose 启动整个 nodejs/mongodb 环境。我在 radcupDevSample.json 中创建了一个 mongodump，我想用 mongo 恢复一个新的 mongodb 容器。在此之后，我想要一个新的节点容器，我的 api 链接到带有示例数据的 mondodb 容器。

我有以下文件：

1. docker-compose.yml：

db:
  image: mongo
  ports: 
    - "27017:27017"`

mongo-importer:
      build: .

web: 
     build: web
     links:
            - db 
     ports:
            - "3000:3000"
      volumes: 
             - ./src:/home/env
      environment:
            NODE_ENV: development

2。网络 Dockerfile：

FROM node
RUN apt-get update -y
RUN apt-get install -y git
RUN apt-get install -y vim
RUN git clone https://sdsds-oauth-basic@github.com/jdklfj /home/app
WORKDIR /home/app/src
RUN npm install
CMD "npm start"
EXPOSE 3000

3. “。” dockerfile

FROM mongo
COPY radcupDevSample.json /radcupDevSample.json
CMD mongorestore -h db /radcupDevSample.json

我使用了这里提到的这个答案： How do I seed a mongo database using docker-compose?

我的问题是：如果我尝试docker-compose up 我得到这个错误：

docker-compose up
radcupbackend_db_1 is up-to-date
Building web
Traceback (most recent call last):
  File "<string>", line 3, in <module>
  File "/compose/compose/cli/main.py", line 54, in main
  File "/compose/compose/cli/docopt_command.py", line 23, in sys_dispatch
  File "/compose/compose/cli/docopt_command.py", line 26, in dispatch
  File "/compose/compose/cli/main.py", line 171, in perform_command
  File "/compose/compose/cli/main.py", line 587, in up
  File "/compose/compose/project.py", line 313, in up
  File "/compose/compose/service.py", line 404, in execute_convergence_plan
  File "/compose/compose/service.py", line 303, in create_container
  File "/compose/compose/service.py", line 326, in ensure_image_exists
  File "/compose/compose/service.py", line 723, in build
  File "/compose/venv/lib/python2.7/site-packages/docker/api/build.py", line 41, in build
TypeError: You must specify a directory to build in path
docker-compose returned -1

有人“提示”我为什么会收到此错误？或者也许有人可以帮我建立这个环境？

谢谢！

附言。分别构建 2 个 Dockerfile 不会引发任何错误...

看起来 docker 无法从您正在运行的当前目录中找到 web/ 目录 docker-compose up

你的结构是这样的吗？

anovil@ubuntu-anovil:~/tmp/docker-compose-mongo$ tree .
.
├── docker-compose.yml
├── Dockerfile
├── radcupDevSample.json
├── src
└── web
    └── Dockerfile

2 directories, 4 files
anovil@ubuntu-anovil:~/tmp/docker-compose-mongo$

我创建了这种结构，然后在运行构建时，

anovil@ubuntu-anovil:~/docker-compose-mongo$ docker-compose up
dockercomposemongo_db_1 is up-to-date
Starting dockercomposemongo_web_1
Building mongo-importer
Step 1 : FROM mongo
 ---> 94a166215fe3
...

为了确保一切正常，我建议您首先从同一目录运行docker-compose build --no-cache，这将确保您从头开始。

anovil@ubuntu-anovil:~/docker-compose-mongo$ docker-compose build --no-cache
db uses an image, skipping
Building web
Step 1 : FROM node
 ---> ac9b478bfbbd
...

然后运行docker-compose up

请告诉我进展如何。
