Docker-compose setup mongodb with data和nodejs server

Question

我想用docker compose.i創建一個mongodump到radcupDevSample.json，我希望mongo恢復一個新的mongodb容器，從而啟動整個nodejs / mongodb環境。 在此之后，我想要一個新的節點容器，我的api鏈接到帶有示例數據的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. web 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

“。” dockerfile

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

我使用了這里提到的答案： 如何使用docker-compose為mongo數據庫播種？

我的問題是：如果我嘗試docker-compose up我得到這個錯誤：

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”為什么我會收到這個錯誤？ 或者也許有人可以幫我設置這個環境？

謝謝！

PS。 分別構建2個Dockerfiles不會拋出任何錯誤......

看起來docker無法從您運行docker-compose up當前目錄中找到web /目錄

你的結構看起來像這樣嗎？

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$

我創建了這種結構然后當我運行我的構建時，

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
...

為了確保一切正常，我建議您首先從同一目錄運行docker-compose build --no-cache ，這樣可以確保從一個干凈的平板開始。

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

然后運行一個docker-compose up

請讓我知道它是怎么回事。
