docker - 我的docker-compose从另一个文件夹中拾取文件，而不是从我运行命令的位置

标签 docker docker-compose meanjs

进入容器后，由于某种原因，它会从该位置读取代码，我不知道代码在哪里以及从哪里加载:
/ home /平均值

但是所需的(实际代码)内容正在此处上传:
/ opt / ltg /

这是我的docker-compose文件的内容，我认为问题在于VOLUMES参数。

当我尝试进入容器并查找html View 时，结果发现它与我以前使用的另一个文件夹链接。

我正在使用https://github.com/meanjs/mean meanjs来构建我的项目，所以我在使用他们的docker文件，也就是他们在使用docker的方式。

version: '2'
services:
  web:
    restart: always
    build: .
    container_name: ltg
    ports:
     - "3000:3000"
     - "5858:5858"
     - "8080:8080"
     - "35729:35729"
    environment:
     - NODE_ENV=development
     - DB_1_PORT_27017_TCP_ADDR=db
    depends_on:
     - db
    volumes_from:
     - web-data
  web-data:
    build: .
    entrypoint: /bin/true
    volumes:
     - ./:/opt/ltg
     - /opt/ltg/node_modules
     - /opt/ltg/public
     - /opt/ltg/uploads
  db:
    image: mongo:3.2
    restart: always
    ports:
     - "27017:27017"
    volumes_from:
      - db-data
  db-data:
    image: mongo:3.2
    volumes:
      - /data/db
      - /var/lib/mongodb
      - /var/log/mongodb
    entrypoint: /bin/true

Dockerfile。 (我认为问题就在这里)，但是即使我将/ home / mean更改为/ opt / ltg，它似乎也不起作用。
 FROM node:0.12

# Install gem sass for  grunt-contrib-sass
RUN apt-get update -qq && apt-get install -y build-essential
RUN apt-get install -y ruby
RUN gem install sass

WORKDIR /opt/ltg

# Install Mean.JS Prerequisites
RUN npm install -g grunt-cli
RUN npm install -g bower

# Install Mean.JS packages
ADD package.json /opt/ltg/package.json
RUN npm install

# Manually trigger bower. Why doesnt this work via npm install?
ADD .bowerrc /opt/ltg/.bowerrc
ADD bower.json /opt/ltg/bower.json
RUN bower install --config.interactive=false --allow-root

# Make everything available for start
ADD . /opt/ltg

# Set development environment as default
ENV NODE_ENV development

# Port 3000 for server
# Port 35729 for livereload
EXPOSE 3000 35729
CMD ["grunt"]

当我进入docker机器时，我可以看到它里面确实有代码，但是我不知道为什么要从另一个地方拾取它。

我不知道这个/ home / mean来自哪里
    "WorkingDir": "/home/mean",

最佳答案

我认为我们需要更多信息才能正确回答该问题。所以我会假设一些事情。

  • opt/ltg目录指向docker-compose.yml所在的目录，而不是您运行docker-compose的目录。通常是同一目录。尝试对您的docker-compose.yml进行修改，例如添加评论。转到带有docker exec的容器，并检查docker-compose.yml的内容，添加的注释应该在那里。
  • 我假设您将html文件声明为卷时也将其转到/opt/ltg/public。 Docker将为此在主机中创建另一个目录，该目录与当前目录不同。使用docker inspect查看它们在哪里。如果运行docker-compose down -v，则应删除这些文件。
  • 除非确实需要，否则不要重叠卷。我建议改用以下docker-compose.yml:

    • docker-compose.yml
    version: '2'
services:
  web:
    restart: always
    build: .
    container_name: ltg
    ports:
     - "3000:3000"
     - "5858:5858"
     - "8080:8080"
     - "35729:35729"
    environment:
     - NODE_ENV=development
     - DB_1_PORT_27017_TCP_ADDR=db
    depends_on:
     - db
    volumes_from:
     - web-data
  web-data:
    build: .
    entrypoint: /bin/true
    volumes:
     - ./:/opt/ltg
  db:
    image: mongo:3.2
    restart: always
    ports:
     - "27017:27017"
    volumes_from:
      - db-data
  db-data:
    image: mongo:3.2
    volumes:
      - /data/db
      - /var/lib/mongodb
      - /var/log/mongodb
    entrypoint: /bin/true
